Problems playing HTML 5 Video on FF 37.0.1

Click for full size
This is a weird one. When watching videos at YouTube I am seeing really weird behavior when html 5 is enabled. Videos will not fill the screen in the standard player. I see a black border often times to the right and on the bottom of the video. If I enable full screen video, the same behavior occurs. Sometimes the video player's controls at the bottom of the video window disappear also. Any thoughts on this ? When I use the flash player everything works fine. When viewing the same videos in Chrome, everything works fine also.

Hmm.. I don't have that problem with 314.22 or 347.88 version NVidia drivers (just updated). Also using 37.0.1 in Windows 7 Pro 64bit.

What if you disable Hardware Acceleration in Firefox?

I have an HTML5 video here: »www.markheadrick.com/dvd ··· on.shtml

is it also messed up there?

I disabled hardware acceleration and it had no affect. I do have the latest Nvidia drivers. But as I said, in Chrome , all is well. I went to your video and played it in full screen and the video was in the upper left hand side of the screen and the rest was black. Also, I have the latest Nvidia drivers. 350.05.

Disabled all extensions and still have the playback issues. Start in safe mode ? No problems at all.

do you have "hardware acceleration" disabled? maybe that is the difference.. "hardware acceleration" isn't used when FF is running in "safe mode"..

I have tried it disabled when running non-safe mode and I am still seeing the same thing. Tempted to start running the FF 38 version to see if the same thing happens.

OK...disabled hardware acceleration, then rebooted the computer. Now it works. Sometimes it is the little things that need to be done.

glad you got it worked out..

i have HTML5 video disabled on my computer so that "adobe flash player" is used instead, for watching videos at "youtube"..

here is an article about how to disable HTML5 video, if you want to:

»www.trishtech.com/2012/0 ··· firefox/

here is all of the settings that i use, to try to disable HTML5 video-and other related things:

disable "loop.enabled" = "false" (disables FF's "hello" feature)
disable "media.autoplay.enabled" = "false"
disable "media.directshow.enabled" = "false"
disable "media.gmp-gmpopenh264.enabled" = "false"
disable "media.gmp-gmpopenh264.provider.enabled" = "false"
disable "media.gmp-provider.enabled" = "false"
disable "media.mediasource.enabled" = "false"
disable "media.mediasource.mp4.enabled" = "false"
disable "media.mediasource.webm.enabled" = "false" (already set to false)
disable "media.ogg.enabled" = "false" (trishtech.com)
disable "media.opus.enabled" = "false" (FF's "hello"?)
disable "media.peerconnection.enabled" = "false"
disable "media.wave.enabled" = "false" (trishtech.com)
disable "media.webm.enabled" = "false"
disable "media.windows-media-foundation.enabled" = "false" (trishtech.com)
-------------------------
i am not sure about all of those settings..
