H.264 played with Flash - must it be in measurements divisible by 4?

I remembered that flash, before H.264, needed to have the height and width divisible by 4.
I asked Squeeze tech support if this was still the case with H.S64, and they said YES.
I've got a 1920 x 1080 that I want to compress to fix a width of 558 pixels.
Compressor sets the height to 313 (if I tell it to use 16x9 ratio).
Should I use this, or go with maybe 316 which is divisible, to get the best possible quality?

It's never been necessary to encode video with a measurement that is divisible by 4. Sorenson was skewing the facts.
The reason it's recommended is that the previous Squeeze codec used a macroblock encoding that was 4 square. The On2 VP6 used a 8 macroblock I believe. The H.264 codec compresses best using a macroblock of size 16. The compression can suffer by not using a frame size that is divisible by these numbers.
That said, it's not necessary to do so. If the quality of the video looks fine after encoding, then you'll be fine.

Can't play with Flash

Hi All,
Does anyone know how to use Flash plugin in Netscape 6 for Solar8 X86. As I know Flash 5 only support SPARC machine and I also try to install it. Anyway I still haven't play with Flash.
CK

There are two different versions of Flash, one version for IE (ActiveX) and another version for all other browsers (Plugin version). You need to install the Plugin version,
1.Download the Flash setup file from here: 
[http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe Adobe Flash - Plugin version]. 
Save it to your Desktop. 
2. Close Firefox using File > Exit 
then check the Task Manager > Processes tab to make sure '''firefox.exe''' is closed, 
{XP: Ctrl+Alt+Del, Vista: Shift+Ctrl+ESC = Processes tab}
3. Then run the Flash setup file from your Desktop.
* On Vista and Windows 7 you may need to run the plugin installer as Administrator by starting the installer via the right-click context menu if you do not get an UAC prompt to ask for permission to continue (i.e nothing seems to happen).

Why am I getting a "QT PLAYER" logo on media files I used to be able to play with Flash and Silverlight?

When I try to download a video file I am getting a "QT PLAYER" logo and it wont allow me to open in Quicktime mor any other media player. Why is this happening? I think it happened after I tried to download plug-ins for Elmedia player? thanks

I dont need you to respond but I found out the answer and I thought I might share it so that if anyone else has the same problem you will know the answer. This what I did before the problem started:
1. I am running MAC OSX 10.8.2 (Mountain Lion)
2. I down/loaded (d/l) ADOBE FLASH player
3. I d/l Adobe AIR SKX including SHOCKWAVE (thought that MORE is better!)
4. Saw that SAFARI had some NEW EXTENSIONS so D/L a few including:
    -Adware Blocker
    -Facebook Ad blocker
   - Facebook page cleanup
   - "CLICK-TO- FLASH blocker (this is the culprit!)
"ClickToFlash prevents the Flash plug-in from running. It replaces any Flash element on a webpage with a placeholder; simply click the placeholder to load the Flash content. ClickToFlash also lets you replace Flash videos from select websites (such as YouTube) with H.264 video. Other optional features include advanced whitelisting". Quote from Safari extensions page.
and a few other unimportant ones in my opinion.
REMEDY:
1. I checked everything about SILVERLIGHT as was suggested and UNINSTALLED SILVERLIGHT.
    WENT TO UTILITIES IN APPLICATIONS AND IN SPOTLIGHT WROTE "SILVERLIGHT" and then "MOVED TO TRASH" anything to do with
    Silverlight
2. did the same for ADOBE FLASHPLAYER and Went to UTILITIES and removed anything to do with Adobe, including the LOCKED ADOBE FILES
    AIR, SHOCKWAVE, AND A PLUG-IN CALLED "DIRECTOR.SHOCKWAVE"
3. THEN UNINSTALLED ALL THE SAFARI EXTENSIONS - especially the "CLICK To FLASH extension.
4. Went to SAFARI PREFERENCES, and under the SECURITY TAB made sure "enable plug-ins" was checked.
THEN:
1. RE-INSTALL SILVERLIGHT
RESTART
2.RE-INSTALL ADOBE FLASH PLAYER (LATEST) 11.2.502.146 here;
http://get2.adobe.com/flashplayer/
RE-START
AND THIS SOLVED THE PROBLEM. NOW WORKING PERFECTLY
MANY THANKS

Hi all new here. Newb question...can this be done with flash?

Hi everyone hoping you can help a newb like me out. Thanks in advance for your time. I am trying to make a video exactly like this.
http://www.youtube.com/watch?v=UbMOTNI8tcE
I know in the video it implies he uses a light control thing but I think he is really just animating the cartoon. I just want to animate a "line cartoon" like this one. Can I do this in flash? Its not for a website just like a movie type thing. I have access to pretty much all the other adobe software at my school so if I need to use a different program I can do that. Just looking for someone to point me in the right direction and maybe give some tips on how to go about it. Thanks.

open flash and you'll see a timeline with frames (that are all empty when you start). draw something on the stage. that will be in frame 1. right click on frame 10 and click insert keyframe. your drawing will be in frame 10 now. double click your drawing to select all of it, move your mouse off and then over the select drawing and then drag it to the right and release. right click between frame 1 and frame 10 and click motion tween. test your movie.
now start playing with flash to see what you can do. you're not going to learn how to create your animation by asking questions.
you can get help getting started but you now have enough info to get started. you can get more help if and when you encounter problems.

MP4 H.264 video won't play in Flash Player

I am using a Mac Book, OS X 10.8.5; FireFox 32.0.1; Flash Player 16.0.0.305. I am trying to play video (MP4 H.264 format) that works on VLC, Quicktime Player & Real Player but won't play through Flash Player. Why?

I'll take a look at the GPL sources to see how the firmware encodes the video output, I think the mpeg encoder might be built into the firmware's Linux kernel (instead of a stand-alone encoder program), I see references to the IBM mpeg2 headers but I'm not sure. But honestly addressing this possible bug is not the first thing on my todo list, but I do fidn this report interesting enough to merit investigation.
May I ask what you are using for the Samba server (aka windows shares)? Do you use your desktop PC, or perhaps a NAS server?
As an interim thing to try, I advice you install VLC media player to view the files, or to use VLC to examine the media files properties to see what you can findout.
IF you must use Windows media player, then I suggest you look into the combine community codex package.

QT H.264 files with two audio tracks. Quicktime plays 2nd track first. ***?

I've been experimenting with H.264 (AVC) and my DVDs. Using Handbrake, I ripped a DVD to MP4 (H.264) and including the director's commentary as the second track.
When I play the MP4 with Quicktime Player, it plays the director's commentary instead of the main soundtrack. VLC, however, correctly plays the first track (main movie audio track) and it allows me to select the second track via a menu.
To get Quicktime to play the proper track, I have to open "Movie Properties" and manually uncheck the second track. This was never a problem with DivX/XviD encoded files with two audio tracks; Quicktime Player correctly played the first track.
Why does Quicktime ignore the first audio track in MP4s (but not AVIs) and is there a way to correct this?

I do have QT Pro.
H.264 files are usually saved in a MP4 container. That's what Handbrake, ffpegX, and D-Vision create, anyway.
The "Choose Language" option is greyed out (unavailable) when I open this H.264 MP4 in Quicktime. If I try to change the settings in "Movie Properties," it says that I must save it with the .MOV file suffix.
It makes no sense to me that Quicktime Player can correctly identify the main audio soundtrack in a XviD file with an AVI container but not in a H.264 video with a MP4 container which Apple has been touting as the latest, greatest thing. Even VLC, an open source product still in beta, gets it right.

Videos will no longer play with firefox but will still play with explorer. I reinstalled flash player. tried resetting nothing seems to help

I have tried everything I know and nothing has worked. Yesterday everything was fine and today I can't get videos to play. I have tried Youtube and various news sites as well as Yahoo news. All I get is a blank screen. I tried it with Internet Explorer and all work. Anyone have any ideas?

There are a number of active threads concerning the latest Flash player plugin (11.3) and the latest Firefox (13). Not all users are experiencing the same issues, but things to check include the following:
- Conflict with Realplayer Browser Record plugin (to disable this, open Add-ons from the orange Firefox button or the classic Tools menu and look under the Extensions and Plugins categories)
- Conflict with Flash 11.3 Protected Mode (see [http://forums.adobe.com/thread/1018071?tstart=0 Adobe Forums: How do I disable Flash Player's protected mode for Firefox?])
Scanning down the front of the forums probably will yield additional suggestions: https://support.mozilla.org/en-US/questions

Click to play doesn't work with flash

I've "click to play" for plugins enabled (plugins.click_to_play is set to true in about:config) in Firefox (v16.0.1) and it works with all plugins (as far as I can tell) except with flash. Every time I enter a site with flash, like Youtube for example, the "lego" icon doesn't show up and it starts playing the videos automatically.
I've tried enabling and disabling the plugin, and reseted firefox but it didn't worked.
I would appreciate any help on solving this issue.

Click to play is a very experimental feature, and shouldn't be used unless you are a developer working on the feature. You should immediately disable click to play until it is fully developed.

Firefox crashes after Flash videos play with black screen

Whenever I'm playing a video with Flash, the screen is black although the sound is playing. Then Firefox is crashing.
I'm using the newest Firefox Version (28.0) on Mac OS 10.9.2 (newer Macbook Air) and the newest Flash version. I tried Safe mode and deactivated my plug-ins to make sure it's Flash.
I re-installed Flash and installed but it didn't help.
My Firefox crash reports say "hang | libsystem_kernel.dylib@0x15a3a" under signature and "EXC_BREAKPOINT / 0x00000002" under crash reason.

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

Flash videos playing with audio echo on initial load.

I have been having issues playing Flash videos in the current version of Firefox (10.0) as well as the previous version (unknown) over the past few months.
When I open a page with a video it will begin playing with an echo as if two videos are playing at the same time with a slight delay on the second video causing an audio echo effect. So basically one video with echoing audio. The websites that I experience this the most are yahoo sports (happens practically every time) and gamespot (happens occasionally). If I refresh the page the echoing effect goes away.
I am running Windows 7 64-bit.
I have updated video drivers on my ATI Radeon HD 5800 series.
My flash player / shockwave is 11,1,102,55 (updated) but I know I have experienced the same problem with previous versions.
I have the following plug-ins enabled:
1. Adobe Acrobat 10.1.2.45
2. Current version of Ad-Block
3. Divx Plus Web Player 2.2.0.52
4. Divx VOD Helper Plug-In 1.1.0.6
5. Microsoft Windows Media Player Firefox Plug-In 1.0.0.8
6. Quicktime Plug-In 7.7.1 / 7.7.1.0
7. Real Player 32 Bit Plug-Ins (4 total plug ins) 15.0.0.198
8. Veetle Plug-Ins (3 total plug ins) 0.9.17.0
I have some others as well but I thought these were the only relevant ones.
Can anyone help me with my problem?

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

Help with Flash Player- Not Playing

I recently went to a website where it said that i needed to
download the latest version of Flash Player. I followed the
directions and installed it, and the movie came up after
installation, but on the website it still said i needed to install
flash player again. I went through the other forum posts and tried
everything, but it still wouldn't show up. Then today i was on the
website and finally the video came up, but then when i refreshed
the page the video was gone and it again said i needed to install
the latest version of Flash Player. The video has shown up twice in
the past day, then says i need to reinstall again. I've tried
everything, but the videos just wont show up. Does anyone know how
to fix this for good?

JDB... your problems and solutions are different (and much
more complex). Read this CAREFULLY.
Printable, lovingly formatted versions of these steps, valid
as of 9/15/2007 are available. I recommend printing them and
following along with the print version:
.doc:
http://www.supportflash.com/bent/flash_player_ocx_troubleshooting.doc
.pdf:
http://www.supportflash.com/bent/flash_player_ocx_troubleshooting.pdf
The issue is this: You have multiple accounts on your XP
machine. One account plays Flash no problem, the other doesn't,
although both are Administrator accounts. Or possibly you have only
one account, and that account fails to play any Flash content. In
any case if you have ANY odd trouble with the Flash Player ActiveX
control for Windows as of September 2007, these should be your
steps. And yes, you need to do both sets of steps, in order!
The cause: This is usually caused by either or BOTH of the
following problems:
1. Leftover locked bits of an old Flash Player installation
2. Registry permission errors (aka 'ACL's)
OK so what do you do about this?
ONE: Identify possibly leftover Flash player bits
a. Open C:\WINDOWS\system32\Macromed\Flash folder.
b. Download the latest FP uninstaller from
http://www.adobe.com/go/tn_14157.
c. Run the uninstaller. If you get a notice saying you need
to reboot, then reboot.
d. Look at C:\WINDOWS\system32\Macromed\Flash folder.
e. Does any file ending in .ocx remain? (flash.ocx,
flasha.ocs, flash9d.ocx etc...)
e1. If no, then you don't usually have any leftover locked
bits.
You're done with this part of the problem, proceed to TWO.
e2. If yes, then that remaining .ocx file may be locked.
Right click it
and select properties and look at the version tab.
What is the version number?
f. Is the version number Flash Player 9.0.16.0 or earlier?
f1. Use the uninstaller instructions from this technote:
http://www.adobe.com/go/4da116d3
-- section "Flash Player 9.0.16.0 and earlier"
-- DO NOT re-register the uninstaller. ONLY do this
UninstFl.exe part.
Yes, you'll need to know how to use the command line to do
this. If you're not
comfortable with that then take your machine to someone who
is!
g. Is the version number Flash Player 9.0.28.0 or higher?
g1. Use the uninstaller instructions from this technote:
http://www.adobe.com/go/4da116d3
-- section "Flash Player 9 (9.0.28.0) and later"
-- DO NOT re-register the uninstaller. ONLY do this
UninstFl.exe part.
In both the D and E sections above you'll need to use the
specific name of the control that remains
in the C:\WINDOWS\system32\Macromed\Flash. So if you had a
stuck flash9b.ocx[DJM1] in the folder
and version was 9.0.28.0, your uninstall command would look
like this:
UninstFl.exe -u
c:\windows\system32\Macromed\Flash\Flash9b.ocx
That said, if you have trouble running these commands it
really is necessary to find someone who knows how
to use the command line, either a friend or a local
professional. Or spend some time learning about the
command line yourself.
h. RERUN the uninstaller you downloaded earlier. This should
get rid of the remaining (now unlocked) .ocx file and fix any
registry keys associated with it.
ALL of section "ONE: Identify possibly leftover Flash player
bits" is important. BUT this locked bit problem only happens on
maybe one out of 50 machines. So most people with installation
problems such as this are not going to have locked bits.
AND even after reinstalling you may still have continued
problems with Flash Player not being recognized.
Then we have to move on to section two..
TWO: Registry Permission Problems
We have been working on Flash Player failures caused by
Windows System Registry issues. We have not been able to determine
what’s causing these permissions to change. But that change
prevents the successful installation of Flash Player ActiveX
control (used by IE Windows).
Registry permission problems can be resolved using a tool
called SubInACL, built by Microsoft to correct system registry
issues.
Symptoms: What to look for:
1. If you install Flash Player on IE and are unable to see
Flash content on any webpage
2. After installation C:\WINDOWS\system32\Macromed\Flash
will have flash 9c.ocx in it but it failed to register
3. It appears that Flash Player installed correctly, but
unable to view Flash content
4. Flash Player works on other browsers, but NOT Internet
Explorer
5. If you are missing groups in HKEY_CLASSES_ROOT Advanced
Permissions
6. If you have run registry cleaners in the past, this may
have corrupted your system
Warning: The following solution involves the Windows System
Registry. Editing or manipulating the registry incorrectly can
result in serious system damage which may require re-installation
of the operating system. If you are not comfortable editing the
registry, then take your system to a professional. If you choose to
proceed, then it is essential that you create a complete system
backup and a Windows System Restore Point before proceeding. Adobe
Systems cannot be held responsible for damage resulting from this
information.
1. Select Start > Run
2. Type in “regedit”
3. Right click on HKEY_CLASSES_ROOT
4. Select Permissions
5. Select Advanced
For Vista
Compare your permissions with the ones in this screenshot.
http://www.supportflash.com/vista_key.png
For Window XP Pro or other flavors of XP
Compare your permissions with the ones in this document
“Troubleshooting system registry issues that prevent Flash
Player installation” (scroll down to the bottom of page).
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=kb400116
Notice any major differences, missing groups, incorrect
permissions?
How can you repair the System Registry, what's the fix
Download SubInACL from Microsoft to fix permission issues
that prevent the Flash Player Installation.
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=fb1634cb
NOTE: The Microsoft version of the .cmd script run by
SubInACL is not be run on any XP version other than Pro. HOWEVER,
the Adobe .cmd script in the above technote is tested safe for ALL
VERSIONS OF XP!!!
If you have a Windows System Registry permission issue that
sounds like the one described above, SubINACL may be the solution.
Please note that if you have this issue on multiple accounts on one
machine you’ll need to fix each machine individually.

RAM usage by Adobe Flash Player spikes when playing online flash games with 3D graphics

Hi. I have recently noticed a spike in RAM usage by my flash player plug-in whenever I play online flash games that use a 3D graphics engine (for example, Farmville 2 and Chefville by Zynga). Apart from the numerous times I receive an error message that the plug-in has failed, my RAM usage goes above 70% from the regular 40% with the plug-in consuming more than 1Gb. I have experienced the problem with the updated version of Adobe Flash Player on the newest releases of Firefox, Chrome and RockMelt. This spike in usage usually leads to a crash of my GPU (ATI Mobility Rabeon 4650 - 2Gb) My specs are as follows:
OS - Windows 7 Home Premium 64-bit
Processor - Core i5
Speed - 2.27 GHz
RAM - 4.00Gb (3.86 Gb usable)
HDD - 500 Gb (465 Gb usable)
I should also note that the required specifications for the latest version of Flash Player (11.7.700.202) requires processing speeds of 2.33Ghz. Could that be the issue? I am still to attempt downgrading of my Flash version to see if that could help reduce the RAM usage. Are there any other suggestions out there?

Hmmm... Win 7 will run faster than Mavericks with 8Gb. Even my Vm of 7 runs faster once I get it past all the startup processes.
It may or may not be a connectivity problen since Windows uses a different protocol, even though it's on the same hardware. Usually though, what affects OS X will affect BootCamp too.
What browser?

High CPU usage when playing flv files with flash

As more and more FLV videos are moving to HD, I'm noticing
high CPU usage and lots of dropped frames when playing FLV video in
web browser with Flash 10. This is true even if the video isn't
full screen. I've tried a variety of browsers (Firefox, I.E.,
Chrome) and the problem occurs on all of them so it's pretty clear
it's a limitation in Flash.
Now my PC isn't high end (it has a Pentium M 1.86 GHz
processor), but I can take those same FLV files and load them in
something like Media Player Classic or Windows Media Player (when
using ffdshow) and play the FLV files full screen with little or no
drop in frames and an acceptable CPU rate.
This is especially annoying on sites like YouTube where I
actually have to save the video and play it back in something other
than Flash to have it play back at an acceptable rate. This doesn't
work for other sites like Amazon.
Why is the CPU usage so high when decoding and displaying
videos when compared to other media players?

I've been doing research about this excessively high CPU usage problem (100%!) for weeks because I have also experienced it with my vista home premium laptop. Just recently, I have finally found the solution. The problem is not your browser or your OS or your pc's memory. The problem is caused by authorization for flash player.
Read the link (posted below) carefully and follow the steps accordingly. If you have already done steps 1 through 6 with your computer, you can go straight to step 7.

Please let me know also if the link solves your problem. I am sharing this because Adobe seems unable to provide solutions to this, and I don't want to hear people suffer.
