[SOLVED]bad video performance in mplayer

I have dual-core 1.4 ghz core duo on my laptop and 32 bit system.
When I try to play h264 encoded files mplayer says:"Your system is too SLOW to play this!".
I noticed that only one core is loaded during playback.
That's why I want to play video on both cores.
This option
-lavdopts threads=2
does not help(it's supposed to make more threads for h264 and mpeg1,2).
CPU load is still mostly on one core.
And when cpu load is high framedropping starts.
Is there someone who tested mplayer on multicore system ?

Read the latest news item (2009-02-20) on MPlayerHQ. ffmpeg-mt works pretty well on my lowly Intel Atom.

[SOLVED] streaming videos directly to mplayer?

basically what i want to do is watching online videos from the shell via mplayer and elinks w/o downloading them, but not to be limited to youtube, so youtube-viewer is not an option. problem is that mplayer doesn't seem to do the job. some claim you only have to pass an url as an arg for it and that's it.

but that's not it, alas. i passed in different cache sizes as well, but that didn't help either. the funny thing is that youtube-viewer uses mplayer as well and worked perfectly out of the box. i looked at the script and mostly additional args are there as extras.

return $smplayer; # Windows MPlayer
else {
my $mplayer_path = '/usr/bin/mplayer';
return -x $mplayer_path ? $mplayer_path : q{mplayer} # *NIX MPlayer
anyone had this issue before? i really could use some ideas. thanks in advance

[SOLVED]Terrible Video Performance on ATI Rage Mobility Card

Hello everyone, I just recently picked up an older Dell Latitude C800 from Craigslist and have installed Arch on it. My problem is 3D performance is really bad.

Installed Radeon 6870 - bad video performance in VLC

I've added a Radeon GPU to my i3-530 which used to handle video. I installed the opensource drivers and I get occasional lags, choppy parts during video playback using VLC. I tried adding the following to my radeon conf as per wiki but that caused tearing:
Section "Device"

Driver "radeon"
Option "AccelMethod" "EXA"
EndSection
I assume KMS is enabled, since that's the default. I don't know how to check though. What could be going wrong?
Thanks

I tried. The way I understand he's simply telling me to install the packages he has listed, correct? I did that via AUR and yaourt. As I said, I could install most of them but not mesa-full. I'm trying again now so I can post the error I get....
Didn't do anything different than the last two times and this time mesa-full installed successfully. Some packages still don't want to cooperate but I'll reboot and see where I stand.
Problem persists. I get an error installing lib32-libdrm-git:
error: target not found: gcc-multilib
and I think that x86_64 doesn't apply to me on my intel CPU so now I've installed everything and the videos still have their stutter moments. Makes me want to cry. I should be studying for exams but this is such a nice excuse not to...

My Many Irritations (story) and a New Solved Problem (video playback)

This topic is just going to ramble through the many things that have irritated me about my iPod since the purchase only three weeks ago. Don't get me wrong, though, I still love the thing. For the most serious problems, check out Numbers 3 and 11.
Lets see... where to begin...
I originally had no interest in the iPod, but some time after the unveiling of the fifth generation's new capabilities a friend of mine started talking about it quite a lot. And so, some time in early November, my hype for the video iPod had grown greatly. I downloaded Videora iPod converter and started converting music videos like crazy.
By the time December rolled in I had successfully converted almost all of my 150 or so music videos and imported them into iTunes. With Christmas coming up I was wondering if I should just ask for it as a gift, but impatience set in and I bought it on the fifth of December, and have greatly enjoyed it since.
Sounds peachy, but there's a fair bit that I left out.
Number 1. I love viewing movie trailers on Apple's website. But with the recent update to the quicktime software, it was required to get the updated version. With that came iTunes, a program that was at the time unwanted and an irratation.
Number 2. Videora iPod Converter has it's fair share of bugs. While I successfully converted many a video with it, I found it would 100% of the time fail to convert files of the .wmv format (Windows Media). As well, I would later find a more serious problem.
Number 3. On the first day of using the iPod I had a serious error. I had been watching videos just fine all day, and the iPod was working perfectly. I then chose a video to play and inexplicably the iPod froze. These are the symptoms: black screen, backlight on, no responce from controls.
Tired, as it was the end of the day, I was unwilling to go to the computer room and attempt to find a solution online. And so, I gambled that the backlight would drain the battery and hoped that upon a recharge, everything would be fine. As the backlight was illuminating my bedroom, I put the iPod in it's sleeve to dim it a bit and went to sleep.
As you can imagine, this was kind of scary. I was afraid that I had bricked my iPod on it's first day.
In the morning, the battery had died and I was able to recharge it by syncing it with my computer. After charging, I tried a few videos and then tried the offending video. Again it froze, but this time I was confident that the backlight would drain the battery and it would be fine.
I then looked at the folder wherin I had saved the converted video. Among all my other videos was the offending one. I played it in Quicktime 7, and everything was fine until I realized the length of the video was double what it should be. After what should be the end of the music video came two minutes of a white screen. The file size was also abnormally large, compared to the other videos.
It turns out that Videora iPod Converter can sometimes produce corrupt files, and these corrupt files will not be detected by iTunes as corrupt. Such files can be trasferred to iTunes and to your iPod without any error or problem, but will lock up your iPod when played. Now, when converting batches of videos with Videora, I scan the file-sizes to see if any are abnormally large; after all, using the same settings on a batch of similar in length videos should produce files of similar size.
It occurs to me now that the method for resetting the iPod might have worked as an alternative to draining the battery.
Number 4. I should mention that the battery life on this thing was (for me) unexpectedly low when playing videos. I'm not saying that mine is defective or anything, but I just found that the battery runs down pretty quick when playing videos; quicker than I had thought it might. Not a big problem, though.
Number 5. In a search to find something to convert my .wmv videos to an iPod compatible format I found the ImToo converter. It works quite well, but the trial version is limited to videos of five minutes or less in length. I'm considering paying for the full version, but if someone knows of another reliable .wmv converter, I'd be glad to try that. For now, ImToo is good enough as most music videos are less than five minutes long, but I do have some other videos in the .wmv format that I would like to transcode.
Number 6. In mid December I went out of town for three days. Of course, I brought along my new favorite portable media player. Not surprisingly, the battery soon ran low and I was without my computer to recharge it. So I went out to a store and bought Apple's official USB Power Adapter. I thought it was kind of expensive, especially considering that they used to be BUNDLED with the older iPod models, but I was happy to find I would now be able to charge my iPod. Wrong. Something that was not made obvious to me by the package description (if it is even mentioned there) is that the darn thing needs the USB cable that came with the iPod. It does not come with one, and so if all you have is a wall socket, the USB Power Adapter, and an iPod, you're screwed. Unless it's the iPod shuffle, which apparantly is the only thing that works with the USB Power Adapter out of the box. As far as portability goes, I feel this hurts. I would have liked to keep my USB cable attached to my computer. After all, it is a pain to get to the back of my computer and keep plugging it in or unplugging it.
Number 7. I'm rather irritated with certain aspects of the iPod's interface considering music videos and regular song files. I spent a good amount of time adding artist and album tags to all of my music videos. These tags make sorting the videos in iTunes much easier.
First, the iPod's interface does not allow for the search of videos through album tags, but does through artist tags.
Second, going to Music>Albums> gives a long, cluttered list of Albums because of all of my music videos and one-hit songs that belong to only one album each.
I suppose there is a workaround.
Number 8. I recently bought another accessory for my iPod. The LOGiiX Amplified Fold-Up Speakers. A very attractive and portable set of speakers for the iPod. It comes with a little stand that holds the iPod in place, and works off of either 4 AAA Batteries or AC Power. Yet again, this is a product that DOES NOT come with the power adapter. Now, I think I MAY have one somewhere in my house... perhaps the power adapter that CAME WITH my SONY MD that is being replaced with the iPod will work....
Oh, and that little clip-on stand I mentioned? I expect it to be lost soon because when I fold up my portable speakers there is no way to clip the stand onto the outside of the speakers.
Now, as far as portability goes, I have to carry with me (at the most) seven things: the iPod, the headphones, the USB connector, the USB power adapter, the fold-up speakers, the little stand, and an AC power adapter.
Number 9. Minor irritation in my control of the clickwheel. After this long, I still accidentally select the wrong thing, and often take a fair time to get the highlight where I want. Meh, this one I'll figure out eventually.
Number 10. There was something irritating about entirely forgetting my login for my Apple ID and having to create this brand new one for today.
Number 11. Just today, I have come across a problem with the video not playing. I watched one video just fine, went to the Videos>Movies> tab and, as mentioned above, accidentally highlighted a video I did not wish to play and hit the Select button. Normally when this happens I wait until the video has loaded - when the screen goes black and the white Play symbol appears in the top left. But this time, I immediately hit the Menu button to go back to the Movies tab. The video's loading was interrupted and I went back to the Movies tab.
Now, when I select and play ANY video, after a noticable but short wait the screen goes black, another noticably longer wait and the play symbol appears, and then a black screen for a few seconds and the iPod skips ahead to the next video, which behaves in the exact same way.
I have powered down the iPod using the method of holding the pause button, but the problem persits.
My music videos can be played as songs by finding them under the Music tab, but no videos play as videos.
I am not at my home computer, and so running iPod updater or just trying to sync is not an option right now.
I will soon try to reset the iPod using the method described on Apple's support website.
EDIT Okay, the reset did the trick. Videos are playing fine now. I still want to share my iPod story, so I'll leave this here, but have changed it from being a question. Below are the instructions I followed for the reset.
RESETTING THE IPOD
1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
2. Press and hold the Menu and Select buttons until the Apple logo appears, about 6 to 10 seconds. You may need to repeat this step.

Nice Rant session:
"It turns out that Videora iPod Converter can sometimes produce corrupt files, and these corrupt files will not be detected by iTunes as corrupt. Such files can be trasferred to iTunes and to your iPod without any error or problem, but will lock up your iPod when played.

What did you expect for freeware? Nice effort but because it's free everyone thinks it's a gem. It's not. This web site has been flooded with questions that should be directed at the authors website. Video conversion and editing is not for the beginner. Sounds to me that you have a bunch of badly converted videos that are causing a lot of problems. Videora problems:
Known Bugs
Audio/Video sync
Problem - Output files can be out-of-sync. While no set pattern has been established, it seems to be more frequent with input files of 23.976 fps, non-DVD rips, and WMV/MPG filetypes.
Workaround solutions - Try the custom option '-async 1'. If the disconnect gradually increases over time, setting 29.97 fps sometimes gets rid of the problem regardless of the input fps. You can also use AviSynth to assume the FPS and have the audio sync to that. If it's a sudden disconnect, check your VOB Cell settings in DVD Decrypter settings per this thread. Otherwise, test with an AviSynth script per the DaProphecy's method in the FAQ. For non-DVD files, PSPVideo 9 may be a good short-term solution until the converter stabilizes some more or try something like AviDemux.
Audio track not getting picked up
Problem - The IFO stream rip is fine, but the converted file has no sound. The debug info showed to audio track getting picked up. The most obvious case with this is the Madagascar DVD.
Workaround solution ideas - Test with an AviSynth script per the DaProphecy's method in the FAQ (untested). Use a different DVD ripper.
Program doesn't start (.NET issue?)
Problem - Converter errors upon starting with an extended dump.
Solution ideas - Update .NET framework (in all languages you're using!) to most recent solution. Clean out registry. Neither of these have worked for some.
Progress meter incorrect
Problem - During transcodes, the progress meter can be incorrect; thus, transcoding continues after the meter hits 100% and time remaining is zero. People have been seeing this more often with VOB files and/or the H.264 codec.
Workaround - Figure out the length of your movie in seconds and compare that to the 'Processed' field. A 2-hour movie will not finish until Processed hits 7200 seconds.
Artifacts (bad video quality) in darker scenes
Problem - Scenes with darker background colors tend to have more artifacts (blocked video). It's much more obvious on the iPod, so this may be an Apple firmware problem.
Workaround ideas - Use a VBR setting (FQ->VBR, two-pass A->VBR) to improve video quality. The custom option '-mbd 2' might help.
Desktop icon
Problem - When installing, the desktop icon does not appear/stick when using lower color setups.
Workarounds - Select a 32-bit color scheme in your desktop settings, or change the icon in the shortcut.
Profile changes don't always stick
Problem - If you make a change to a profile, click apply, and immediately trancdoe with that profile, the transcode might not use the new settings.
Workarounds - Once you click apply, swtich to another profile and back again to make sure the change is still there. If that doesn't work, create a new profile.
Can only install/use with admin rights
Problem - There have been reports of non-admin users not being able to use the converter.
Workarounds - Separate installs or give all users admin rights.
Who in their right mind would use a program that has these many critical bugs to convert files for the IPOD. People who are cheap, kids with no money and people who are just plain gullably.
A little research and downloading a trial from this site would have solved your video problems early on;
http://www.divmm.com/
The 5th Gen IPOD was designed to support video content that was purchased on the ITunes web site. For everything else, you are on your own.

SOLVED: Low 3D performance with Intel X3100 on Arch64?

Hello,
I installed Arch x86-64 on my Acer 7720-6902 laptop, which uses X3100 video (i965 chipset). It works nice, except that I am getting VERY bad 3D performance. glxgears gives only ~400fps and I can barely get 30fps on games like ActionCube.
The other distros I tested here, openSUSE and Mandriva, were 32-bits and 3D worked normally.
Any ideas on how to fix it? This is not a work blocker, just an annoyance, as I don't use this machine for 3D gaming but still would like it working properly.
Thanks!

Get xorg-server and xf86-video-intel from testing. For more information consult this topic.

Regarding video performance.

Hi,
I bought a MSI P7N SLI Platinum 750i chipset based motherboard Sn. 010B0807485693. After 8 months the board would not post, i.e. no display on the monitor even though the Harddisk LED and the CPU fans would run.
Handed over the motherboard to Microport, they sent it to Smartlink Network Systems Limited RMA Center N.R. Road Bangalore, I had to call up about 25 times to Smartlink and they took one month to give a replacement with the MSI P7N SLI Sn. 601-7380-010B0803214616. Got it on 18/9/2009.
The motherboard which I got from Smartlink is much older, as can be seen from the serial numbers. The video quality, i.e. clarity, color as well as frame rates are very bad compared to the original motherboard that I had.
I now know that the original motherboard never had a problem, only the technician at the Microport, Bangalore shop had delibrately not plugged in the power cord for the 9600 gt graphics card and unnecessarily made me RMA my motherboard.
I want to know if the older boards (of the same model i.e. MSI P7N SLI 750i platinum) used a different technology than the new motherboards have?
Is there a way to improve the video performance on my computer with this older motherboard.
Thanks.

All I can say about it is that, as far as I know, the P7N you got back, shouldnt be slower then the one you send in, they should be identical in setup/build.
I have the P6N platinum and the only difference between your and my board is that yours is able to run 45nm C2Q and has 2, I believe, PCIe 2.0 slots, where as I have 2 PCIe 1.1 slots.
But that doesnt make mine a slow board either, with current setup, see my sig, I have 0 issues or performance problems.
If you can, first try different videodrivers, be sure to delete old ones with drivercleaner or such.
If that doesnt work, might try a fresh install on seperate disk/partition and see if that helps.
But if performance still is bad, I would take it back, in my opinion you should not get an older/slower board back if you rma your new one.

Flash video performance poor in Firefox 3 and other newer Gecko-based browsers; fails to detect mouse movement in full-s

Regardless of configuration, I have found Flash video
performance on Firefox 3 to be severely sub-par. Numerous visual
lags occur throughout a typical Youtube video as it cannot seem to
manage to maintain a steady frame rate. When in full-screen, mouse
movement is not detected, forcing me to click in a full-screen
Vimeo video in order to display its controls when I should have
only needed to move the mouse. I was informed that the technical
explanation for this is that Flash isn't triggering MouseEvents
other than MouseEVENT.CLICK.
In my tests, this behavior also occurred in Flashplayers 9
and 10 as well as with recent versions of other browsers that also
use the Gecko rendering engine, namely Camino, Flock and Songbird,
but not in Firefox 2. I was told by a Mozilla employee that this
issue can only be solved by Adobe.
This has forced me to use the Safari browser as my only
available work-around. I implore that these issues get resolved as
quickly as possible.

guys, im exactly experience the same issue here.. any
solution guys? tks in advantage..

Bad Desktop Performance with Dell P2715Q

Hi everybody,
I'm using a 15" Mid 2010 Macbook Pro with the following specs:
- 2.4GHz i5
- 8GB 1067 MHz DDR3
- Samsung Evo 850 (250GB) as Startup Disk
- GeForce GT330M 256 MB
- External Dell P2715Q with MiniDP to DP cable at 2560x1440
- Yosemite 10.10.2
- External Keyboard and Mouse, both wired
Unfortunately (apart from my Graphics Card being unable to output 4K but I accept that, this machine is almost 5 years old) the performance when using normal desktop operations is really bad on the Dell monitor. Some things like scrolling in Finder and Safari work fluently, but most not. Here's a list:
- Minimizing and maximizing, moving and opening windows is lagging
- Horrible video performance when watching Youtube HD videos, especially in fullscreen. Sometimes nothing happens for more than 5 seconds, screen simply freezes
- Lags when using some third-party apps even when only scrolling through text (for example Matlab)
When the issues above appear, the process WindowServer has a very high CPU usage, my computer starts to heat up and burn enormous amounts of energy, gets unusable. I googled the issue with the WindowServer and followed the advice, reducing the transparency helped a little but especially the issue with Youtube videos is unchanged. Even when doing nothing, the CPU usage of the WindowServer never drops below 0.5%. In general, the experience when working on the external monitor is kind of slow and really unsatisfying, different then what I'm used to from the Macbook. From the 8 GB of RAM I have, 5.7GB are used when simply typing this text in Safari apart from having Outlook and a terminal open (plus some background apps like Dropbox).
Things are a little better when working in closed-clamshell mode (mostly the issues with handling windows, HD video in fullscreen still *****).
The only things I haven't tried is resetting the SMC & PRAM since users reported that doing so doesn't help at all.
Any help would be highly appreciated.
Edit: My Yosemite Installation is a fresh and clean installation, nothing was transferred/proted from an older Mac OS installation, apart from some documents of course

Well it obviously supports the resolution (also according to the datasheet) and playing HD video at lower resolutions works fine.. I just saw this:
2014 Macbook Pro 15" doesn't work well with 4k @ 60hz, obvious lag due to high WindowServer CPU utilization
which makes me think that it's not really a performance thing but more a bug in Yosemite.

Conky affects video performance while refreshig itself?

Hi,
today I've installed conky and configured it to run with some basic configuration fond here http://conky.sourceforge.net/screenshots.html.
Happy with new fancy stuff installed on my system I've ran VLC to watch some movie. Unfortunately it came out that conky - while refreshing itself - affects video performance really badly. So badly that some stuttering on VLC is visible. In other words playback is no more smooth.
But just to have a proof I checked glxgears. Having conky turned on I had something like 40 FPS less (lack of smooth animation every time conky was refreshing its status was also easy to notice).
So - is just mine configuration broken or it's conky's fault? I don't believe that no one noticed this problem before.
I have nVidia Quadro NVS 140M and using nvidia-304xx drivers.
Last edited by jakub (2014-11-03 23:58:30)

that shouldn't happen, unless maybe if you ran it on really slow system with no gfx acceleration whatsoever.
Or if you were running some heavy script every time conky refreshes.
It might be a good idea to post the actual config you're using..

Recent ML upgrade leads to widespread video performance issues.

Hello,
I recently took the leap to Mountain Lion and I'm starting to regret my decision. I have noticed a real drop off in video performance across the entire system.
Firstly, I came across a well documented issue with Final Cut Pro 7 video playback in the canvas. Playback is almost unusable due to introduced artifacts and tearing. However the video performance issues seem more wide spread than "unsupported software". I notice extremely rough image switching when I switch between workspaces, particularly on the second monitor. Also, when the screen saver kicks in and it swaps images, the same very klunky image swap is noticed on the second monitor. Also when the Reading List display is toggled in Safari, the remaining window slide left or right is not smooth at all, irrespective of what monitor it is on. There are other Safari rendering issues too, involving flickers, and other general video issues.
My machine is a mid-2010 Mac Pro, 6 core, 3.3GHz with 24GB of RAM and a 5870 graphics card. None of these issues were present in Lion.
I was wondering whether anyone else had noticed similar issues and if so, what if anything can be done about it.
Thanks in advance.
Regards,
Scott

This problem is not restricted to Leopard, 10.4.10 with QuickTime 7.3 is affected too. 10.4.11 doesn't show any improvements either. Yes, we need a fix for this... but one that solves this problem on Tiger as well, please.

Satellite P100 PSPAD: Unable to update BIOS 3.8 and poor video performance

Hello,
I have absolute shoddy video performance on my machine as well as the fan on/off issues.
To add to my frustrations the WinPhlash programme included in BIOS version 3.8 dumps out when trying to flash giving a PHLASHNT.SYS unable to load message with various error codes associated with it (codes 5 and 147 depending on if I run the exe as it is extracted from the ZIP, or run the extracted files independantly).
I have checked all permissionings on the folder and I definately have full control - but still a generic "check your accounts, if you have no permissions please log in again!" message is displayed.
any help with my BIOS issue would be apreciated.

Hi,
I have had the same error message on P100 PSPADE and furthermore the laptop was no longer under control, neither by keyboard or by menu impossible to switch off. I have had to unplug and to remove the battery. Then impossible to switch on.
According to the local ASP the motherboard is KO (??) and the safest way to upgrade the bios was to boot from an USB floppy in DOS mode?
Sounds strange but be careful.

Bad INSERT performance when using GUIDs for indexes

Hi,
we use Ora 9.2.0.6 db on Win XP Pro. The application (DOT.NET v1.1) is using ODP.NET. All PKs of the tables are GUIDs represented in Oracle as RAW(16) columns.
When testing with mass data we see more and more a problem with bad INSERT performance on some tables that contain many rows (~10M). Those tables have an RAW(16) PK and an additional non-unique index which is also set on a RAW(16) column (both are standard B*tree). An PerfStat reports tells that there is much activity on the Index tablespace.
When I analyze the related table and its indexes I see a very very high clustering factor.
Is there a way how to improve the insert performance in that case? Use another type of index? Generally avoid indexed RAW columns?
Please help.

Hi
After my last tests I conclude at the followings:
The query returns 1-30 records
Test 1: Using Form Builder
- Execution time 7-8 seconds
Test 2: Using Jdeveloper/Toplink/EJB 3.0/ADF and Oracle AS 10.1.3.0
- Execution time 25-27 seconds
Test 3: Using JDBC/ADF and Oracle AS 10.1.3.0
- Execution time 17-18 seconds
When I use:
session.setLogLevel(SessionLog.FINE) and
session.setProfiler(new PerformanceProfiler())
I don’t see any improvement in the execution time of the query.
Thank you

Still bad video quality

even is catalyst cs 5.5 two of my problems do not resolve.
bad video quality in fullscreen. i have some videos for offline view (768x576 @ 2600 kbps) but still fullscreen view is messed up, all blocky, not proper video interpolation. in vlc or any other player the flv file looks fine!
the videos also have a 4:3 ratio and show white borders in fullscreen on a 16:9 screen in letterbox, how can make the borders black?
is there any solution?

Hi
as example
Creating a PAL movie in iMovie HD 6 then import this into a NTSC iDVD project
• Works but with a losy quality
I do use JESDeinterlacer3.2.2 and let this do the PAL to NTSC conversion
Now burned as an NTSC iDVD project
• Best result possibly without buying PRO-applications for $$$$$$$
This way should work the other way around too.
Most modern PAL DVD-players can playback NTSC (if TV is old in Bl/W)
Most modern NTSC DVD-players can't playback PAL
If playbacked on a Mac PAL or NTSC is of no interest.

Improving bad video ?

Somebody knows out there an app that is able to enhance a bad video like a 3GP for instance ?
Something smart enough that is able to do the trick and add quality by extrapolating between 2 frames or 2 lines for instance ?

You can use sharpening tools like Unsharp Mask. You can use third party up-rezzing tools to increase size with better quality.
But, realistically, given you only have a camera recording of a video screen of the CCTV, it's very unlikely you'll ever extract much meaningful detail from it. Don't believe TV shows, image enhancement is not really so advanced.
Personally, I'd just extract the best still frame of their faces you can find, then use Photoshop to zoom and enhance as much as you can with Unsharp Mask.
