Screen tearing on video playback with mplayer and radeon driver

I use a old Radeon 9200 video card with the open source radeon driver, and after I configured the radeon driver to fix the screen tearing, it still has screen tearing
this is the xorg.conf:
Section "Device"
Identifier "My Graphics Card"
Driver "radeon"
Option "DRI" "on"
Option "DynamicPM" "on"
Option "ClockGating" "on"
Option "AccelMethod" "EXA"
Option "EXAVSync" "on"
Option "DMAForXv" "on"
Option "ScalerWidth" "2048"
Option "EnablePageFlip" "on"
Option "RenderAccel" "on"
Option "AccelDFS" "on"
Option "AGPMode" "4"
Option "ColorTiling" "on"
Option "AGPFastWrite" "yes"
BusID "PCI:1:0:0"
EndSection
and this is the ~/.mplayer/conf:
vo=xv
ao=alsa
mixer-channel=Master
nolirc=yes
nojoystick=yes
font=Arial
subcp=latin2
subpos=95
and I know that this video card is capable of playback without screen tearing, because if I boot windows xp and open any video file with VLC, there is no screen tearing

I have a Radeon 9250. Here is my setup:
Section "Device"
Identifier "Radeon 9250"

Option "EXAVSync" "false"
Option "ColorTiling" "true"
Option "EXAPixmaps" "true"
Option "MigrationHeuristic" "greedy"
Option "SwapBuffersWait" "true"
Option "TripleBuffer" "true"
Option "EnablePageFlip" "true"
Option "AGPMode" "8"
Option "AGPFastWrite" "false"
Option "BusType" "AGP"
Option "DisplayPriority" "AUTO"
Option "IgnoreEDID" "false"
Option "RenderAccel" "true"
Option "AccelMethod" "EXA"
Option "AccelDFS" "true"
Option "FBTexPercent" "0"
Option "DMSForXv" "true"
Option "SubPixelOrder" "NONE"
Option "VGAAccess" "false"
Option "DRI" "true"
Option "XV_VSYNC" "true"
Option "XV_CRTC" "auto"
Option "XV_BICUBIC" "false"
EndSection
I'm glad with the video quality, however, I do experience little tearing sometimes, especially in the scenes involving panning.
The XV_VSYNC option is supposed to eliminate tearing (due to the radeon manual), but it is ignored if KMS is enabled. Try disabling KMS if you don't mind some performance reduction. The Radeon driver generally has some annoying bugs and glitches in KMS mode.

Problem with video playback with iTunes

Several problems :
Problem with video playback with iTunes -
Since about a week, When I launch a video, it takes a long time to get started, then only the sound starts with no pictures - If I press pause then play the video is played normally. Did anyone face or heard about same kind of issue .
Problem with permission disk errors
After re-installing White Tiger and After I installed the last OSX 10.6.5 update
I found the following problem
Group differs on "Applications / Utilities / AirPort Utility.app / Contents / Resources / wanArrow.png", should be 0 instead of 80.
Last but not least :
My computer seems slow - I have 60gig free on My hard drive and I test my hard drive and everything seems all good .

What was the fix for this? Everything has sucked for my itunes video playback since the last major revision release.

Yes, I am having this problem too (although I was sharing via a "copy link" command, not via email). My workaround fix was to log into iCloud.com via Safari and get the share link there.

Tearing video playback with radeon open source

Hi all, I'm pretty new to Arch. I've got almost everything set up and working nicely, except video playback.
I get a lot of tearing using the open source drivers. It happens both with mPlayer(no matter which output is chosen) and VLC. Happened in Ubuntu and happens in Arch. In Ubuntu the only thing that solved it was enabling Tear Free Desktop from CCC(which enable VSYNC and Tripple Buffering), but I wanna stick to open source drivers in Arch(that's the prefered choice according to the Wiki).
Can I enable VSYNC in these drivers? Please help.
Not sure if it matters, but I'm running GNOME 3.
Thanks!

I am not currently using ATI hardware to tell you exactly what's needed. Using a compositor such as Compiz might make the difference.

Corrupt video playback in Kodi and black screen when emulating.

Hi!
I have a problem most likely related to each other. When I try to play back videos in Kodi the video just gets scrambled, it fast forwards very fast and looks generally corrupted and when I try to start a game in some emulator (for example mupen64plus) the screen just turns black.
Kodi seems to work really well otherwise, it got sounds in the menus and the menus are smooth when navigating. Same with emulators, the GUI (mupen64plus doesn't have one) works well and I can navigate the menus and everything but as soon as I start a game the screen turns black with no sound.
I tried OpenELEC (which is a distribution that has the main purpose of running Kodi) and the video playback works just fine. Sadly it's not very emulator friendly.
The packages I have installed are: "xf86-video-ati" (dependence: "mesa"), "xorg-server" (dependence: "mesa-libgl") and "xorg-xinit".
And the way that I the programs are usually from .xinitrc (example: exec kodi-standalone) and then xinit.
Hardware:
Motherboard: ASRock FM2A78M-ITX+ mITX
APU: AMD A10-7800 (the GPU part is GCN 1.1 aka Sea Islands)
All connected through HDMI
Any help would really be appreciated!

If you use windows (havent checked on mac but it might work)
Disable Direct3D acceleration in the player you are using.
If you use VLC media player, Go to preferences, Video, And under output, change from default to "Direct 2D video output"
If you use Quicktime, Downgrade to Quicktime 7.6 or upgrade to quicktime 7.7.3 and Go to
Edit --> Preferences -->Quicktime preferences.
Under that, go to advanced tab, and uncheck "Enable Direct3d acceleration" (3'rd box)
Fixed the problem for me
You're welcome

Variable Speed and/or Frame-by-Frame Video playback with Waveform synchronization

I'm using Diadem 2011 to view data recorded in a LabVIEW Module that we have written. The function of our LabVIEW module is to simultaneously capture video from two infrared cameras and 8 channels of waveform data from a DAQ and record this data to disk. Data is recorded as two separate AVI files (compressed) and a TDMS file (using TDMS logging). Using Diadem, I use the video synchronization function to view the TDMS data and video files. I can scroll a cursor in the waveform data panel and view the video corresponding to the time selected.
I am looking for two features from Diadem that I am not sure are present: 1) A way to vary the playback speed from real-time. 2) A way to advance the video in a frame-by-frame manner. If anyone has any suggestions on how I might implement this in Diadem 2011 or can verify that these features are present, I would very much like to know.
Thanks in advance.
Solved!
Go to Solution.

Hello Resaebiunne,
All the functions you are looking for are available in the VIEW toolbar.
For the frame reverse/forward functions, please make sure that the section with the video inside is highlighted and then use these two buttons. The "Cursor Parameters" icon let's you change the playback speed.
Hope that helps,

it said deinterlace is available, or am i wrong? someone has an idea?

mplayer man page wrote:deint=<0-4>
Select the deinterlacer (default: 0). All modes > 0 respect -field-dominance.
0 no deinterlacing
1 Show only first field, similar to -vf field.
2 Bob deinterlacing, similar to -vf tfields=1.
3 motion adaptive temporal deinterlacing May lead to A/V desync with slow video hardware and/or high resolu‐
tion. This is the default if "D" is used to enable deinterlacing.
4 motion adaptive temporal deinterlacing with edge-guided spatial interpolation Needs fast video hardware.
It seems that your card may not be fast enough to handle such an option.

Portege R700 - Issues with video playback with resolution over 360p

I've got this video playback issue from day one. While for instance on YouTube, videos with resolution above 360p freeze up while the sound is ok.
I've contacted Toshiba through which I got a linke to the latest bios and drivers. After the upgrade issue persists. I sometimes get a green screen while watching flash video as well. I'm guessing this is a graphic card hardware issue. Any ideas? Thanks! (Portege R700 19L, win7 pro 64)

Hello
Have you tried watching videos in high performance mode and tested different Internet browsers?

Choppy Video Playback with new update 7.5.0.20

Well, here we go again. This latest itunes update is not up to snuff. My video playback has hit rock bottom.. And worst of all, my cpu usage is thru the roof. What the heck dude. You know, I talk to my buddies that own MACS, and of course they never have a problem with their freakin itunes. This has happened before, about a year ago. You can check the video reviews on Battlestar Galactica. I uninstalled and reinstalled, and NADA!!! Same ol' crappy playback. This was not an issue with the previous version. I even performed a system maintenace on my laptop just to make sure the CPU vents weren't clogged with dust. I know that Apple would prefer that the whole world owned a freakin MAC; but for Pete's sake, I am paying them to download content!!!!Paying!!!!!!! Give me something I can look forward to. Dread is what I feel everytime they announce one of their cute updates.

Me too. All I get is audio and a green screen when i try to play a video(that i *paid for* in some cases). I asked a question here a year ago and have yet to get an answer to!

Poor video playback from movies and DVD in Quicktime and DVD player

Hello.
I have just taken delivery of a smashing Intel iMac C2D 20".
I appear to be having problems playing back video and DVD. let me explain:
When entering full screen on a DVD, the picture is very blocky (pixilated). This happens on all DVD discs I have used.
The same happens if I playback a MPEG or AVI, and also when I use Eye TV to playback TV.
I have run the Apple Hardware test, and it returned no faults.
The Video Card is the ATI Radeon X1600 with 256mb
I am sure that there is a problem because I have just compared playback using my old G5 iMac and G4 Powerbook using the same media files and DVD's and they playback fine.
Does anyone have any suggestions (other than calling Tech Support at this stage as I will blow a fuse after being on the phone for 1.5 hours getting nowhere, and with agents not knowing which keypresses to initiate stuff - sorry - Rant over - I just want to get this resolved)
As a side note: I have just installed Windoze XP on a partition, and the playback of DVD and MPEGS are fine - so it leads me to think maybe its software??
Not one to let things get the better of me - I installed Real Player and VLC.
BOTH of these play back the media correctly.
So I guess it is Software for sure, and I guess its Quicktime. Does Quicktime run DVD Player as well?
I did a roll back to a previous version of Quicktime, and it screwed up the mac. It would book, but would not load the Finder.
So I archived and reinstalled, and I had 7.1.2 QT, and the problem was still there. So up again to 7.1.3 and problem still persists.
I have come to the conclusion that this is to do with Quicktime on a C2D processor iMac.
Can anyone shed any light on this or suggest a solution?
Manythanks
Glenn

Problems with mplayer and the framebuffer

I am having trouble running mplayer in the framebuffer using
mplayer -vo fbdev
or
mplayer -vo fbdev2
fbdev plays sound but says that I was unable to open the requisite video device (I am in the video group). fbdev2 spits error messages to the screen, and plays no sound. Currently, I do not have access to the computer with this problem, and cannot post the error messages.
I did, however get mplayer in the framebuffer to work by installing directfb and recompiling mplayer. This time, even though I am in the video group, I am still not allowed to access directfb unless I run as root (it runs perfectly as root).
I'm sure I've missed something simple, but I cant see it. I've read through what I believe is all of the requisite documentation.
Thanks!
edit: More descriptive title.

There's also the "sdl" video output to try. And mplayer and mplayer2 seem to have slightly different behaviour for me. Out of curiosity, what framebuffer driver are you using?

Tearing during video playback

Whenever I'm running any moving image on my iMac, a horizontal line tears the image in two, rising to the top of the screen, to re-appear at the bottom and rise again. I have this in Quicktime, DVD player, Front Row, Safari, games, etc... The tear is also visible when I'm moving windows around.
A second screen connected to the mini-DVI port doesn't have this problem. Running video on Windows XP (Bootcamp) on the same iMac doesn't show the tear either. This makes me assume it's not a hardware issue.
I've read reports that OS X 10.4.5 should have solved this issue, but it didn't work for me. My SMC version is 1.1f5, which is the most recent one I can find.
How can I solve this problem?

I found out what's causing this. I only have the problem when my external LCD TV is connected to my mini-DVI port. When nothing's in the mini-DVI port, my internal display works perfectly under OSX!
Now I like to keep the TV cable conveniently connected to my iMac, wether I'm using the LCD TV or not (it's not on all the time). So I still like to solve this problem.
I'm pretty sure it's software. I wonder if there's a way to alter my graphics card settings so I can run some tests.

Re: Satelite M70 - Video playback really slow and dtrange metalic noise

Hi
I have a Satelite M70 laptop and a few days now I realise that the video (youtube and any sort of videos) playback speed is really slow, slow motion (my interenet speed is fine)
and there is a really creepy kind metal noise when the video is playing.... u cant hear anything just that noise.
Also when i open a file or a menu in windows u get theis king of metalic noise
I have checked the video and audio codecs and are the latest
btw: I can hear audio files from media player just fine. It seems this happens only with videos
Any suggestions cause i cant see any videos!!!!!

I was 100% sure you will post this.
Online playback speed is always different. I have fastest 16000 DSL line and I have noticed the same on my M70 and brand new Satellite P300. Sometimes is youtube or some livestream video perfect and sometimes audio and video don't match together or the video playback is like in slow-motion.
I have also latest drivers and codecs preinstalled on both machines. There is one interesting thing-this slow-motion happen when the HDD led is blinking and when the HDD is running. Please play a little bit with this stuff and watch carefully how it works.
About sound and speakers is not easy to say if they are defective or not. The fact is that sound on headphones works perfectly is evidence that sound card or sound driver is not the problem.
I really don't know what to say but I believe the speakers don't work properly.
What do you think?

CHOPPY FLASH VIDEO PLAYBACK WITH ADOBE FLASH VERSION 10-11

I'm having a problem as described in a previous post re: Choppy flash videos, pictures, etc.. Youtube, megavideo any videos viewed online appear fine at first and then after 10-15 mins, start showing choppy. The audio was not a problem before, but I have noticed that it is being affected as well. I saw some posts on another forum a few days ago that recommended disabling flash player 11 in my chrome browser plugins and enabling verion 10 (which was available, but has since upgraded) and version 10 was working fine until it upgraded to 11 again. Now I have no options to revert to version 10 again.
My system info is below:
Sony:
OS - Windows 7
64 bit
Browser Chrome 16.0.912.77
Browser FireFox 9.0.1
Browser IE 9
Browser Safari 5.1.2
Flash Player 11,1,102,55
McAfee (came with the upgrade of flash player)
This is very frustrating. I've tried uninstalling and re-installing, rebooting the browser, my pc, deleting cache files and cookies...NOTHING IS WORKING. CPU usage is between 20-35% when a video is active in my browser. I think that is normal, but I know that the choppy playback is not and it's only getting worse. Please HELP!
I hope this NEW POST will suffice as per your requirements.

When the video is choppy, how much CPU and RAM usage is occurring? Do you have a graphics control panel that shows how much video RAM is in use when the video is choppy?
Do you have a list of sites and videos where the video is choppy?
If you don't want the McAffee add-on, remove it.

Corrupted DVd playback with VLC and dvdnav

When I play dvds with VLC I get corrupted playback like this:
http://img89.imageshack.us/img89/4964/v … 903ul9.png
Every other type of video i've tried plays just fine. Also if I play the vobs directly the playback is ok. So I'am assuming that the problem is releated to libdvdnav.
I have Acer Aspire 1350 -laptop with KM400 chipset. I've tried the default VIA-driver that comes with X and I also compiled the OpenChrome 0.3.0 RC -driver, but it didn't solve the problem.
I don't know if this problem is caused by OpenChrome-driver, VLC or libdvdnav. Currently I'am using ArchLinux. The problem happens also in all Debian/Ubuntu-variants and OpenSuse. PCLinuxOS is the only distribution I've tried that plays the dvds without corruption.
I also tried Ogle player and it's playback is also similarly corrupted.
Does anyone know what could cause this?

I've the same issue and I don't know how to fix it (my card is an nvidia go5200 32mb which is supported only by nvidia legacy driver which are no more available in arch).
