• WebM Encoded file plays in Chrome but not FFv6 HTML5-Video

  21 novembre 2011, par Austin S

  I'm trying to use the new fancy html5 video player element and I was wondering: I encoded a high resolution .mov container in VLC v1.1.9 to WebM format (although an FFMPEG command line would be extremely valuable if you have one handy) and it plays just fine in Chrome, but it won't open in Firefox. Would anyone have any ideas or in what direction I should be looking?

• ffmpeg assert - throw exception instead of abort

  21 novembre 2011, par ronag

  I'm using ffmpeg in my C++ application.

  When trying to play certain files an assertion inside of ffmpeg fails, which causes it to call abort() which terminates my application. I do not want this behavior, rather I want to get the chance to recover, preferably through an exception.

  Anyone got any ideas as to how I can get around the problem with ffmpeg/assert potentially terminating my application?

  EDIT:

  The only way I can think of right now is to change the ffmpeg assert macro so that it causes an access violation which I can catch through SEH exceptions. Ugly and potentially bad solution?
