User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:34.0) Gecko/20100101 Firefox/34.0 (Beta/Release)
Build ID: 20140801030201

Steps to reproduce:

I set to true, restarted firefox and visited youtube. I started to play a video there.

Actual results:

Firefox crashes.

Expected results:

The video should play.
It's important to mention that I'm on the yosemite beta. Sorry for not mentioning it in the beginning.
Perhaps this console information helps:

Can you got to about:crashes and paste a link to the corresponding backtrace?
Thanks. These all crash in the ReorderQueue::Push call from AppleVTDecoder::OutputFrame().

I can't reproduce with youtube and a debug build; it serves me vp9 and aac so the video decoder isn't active. Can you share a specific url that crashes for you?
I don't think it matters what video I select. It just happened here: It instantly crashes so I can't find out which codecs it uses.
I hit this same crash on any MP4 video, local or remote. And I'm also running the Yosemite beta.

I still can't reproduce on Nightly or my own debug builds, MacOS X 10.8.5.

I can get youtube to serve me (non-dash) mp4 if I set

  media.mediasource.enabled = false
  media.fragmented-mp4.enabled = true

But it doesn't crash for me. This will be hard to debug without a video which reproduces.
@Ralph Giles
The keys/values you mention are the default values for me. I additionally have set to "true". And I guess it might have sth. to do with Yosemite.
Oops, yes. I also tested with = true. Otherwise I get webm from youtube.

I also tried Nightly on a 10.9.4 iMac and couldn't reproduce. Maybe it's specific to 10.10.
Reproduced on OSX 10.10 DP5 with Nightly 34.0a1 (2014-08-05).  After crashing once, it was necessary to clear browser history to reproduce the issue a second time.
Thanks, kip. I guess we can conclude it's specific to 10.10.
Summary: youtube makes firefox crash on OS X with platform decoder exposed → youtube makes firefox crash on OS X 10.10 with platform decoder exposed
I've been able to reproduce on a loaner Mid 201 11-inch MacBook Air running 10.10.
Depends on: 1044497
It's not the same stack, but I have been able to get a crash on 10.9.4 just by setting to true and attempting to watch a youtube video: (and it seems others have with the same stack as me, too:*%29#tab-reports)
That looks like a different bug, unless there's memory corruption involved. Can you share a specific youtube url which reliably crashes?
Sadly... no, it seems I can not. Every one I try now works just fine (of course). No changes to my profile or build or anything, everything "just works". I'll file a new bug if I find something reproduceable.
So the good news is that the JSConf video is crashing on 10.8 for me today. The bad news is it's a different backtrace, so we probably have memory corruption.

nsAutoPtr<MoofParser>::mRawPtr is 40.

ConvertByteRangesToTime() is being called on a null MP4Demuxer::mPrivate::mVideoIndex. I suspect this is a new bug shadowing the 10.10-only one.
I can no longer reproduce with today's tree or Nightly build now that bug 1050060 is fixed. Maybe that was the problem all along?

Beingalink, can you confirm with a 2014-08-14 or later Nightly?

I'm on 2014-08-14 Nightly and I still get this crash instantly.
Flags: needinfo?(beingalink)
Still crashes for me as well, trying to play a video off my drive.

This doesn't fix playback, but should at least avoid the crash.

I can confirm that the crashing is fixed. Audio on youtube plays fine but the video stays black. There seems to be some issue with timing (see attachment).

> There seems to be some issue with timing (see attachment).

The incorrect duration is unrelated to this bug. See bug 1050814.
Thanks for confirming. The duration issue is bug 1050814.

I've filed bug 1054789 to follow up on the decoding issue.
