FFmpeg Arquivos convertidos que não funcionam no firefox

Question

Quando eu converto um arquivo com ffmpeg e reproduzo o vídeo no firefox, recebo este erro:

"VIDEOJS:" "ERROR:" "(CODE:3 MEDIA_ERR_DECODE)" "The video playback was aborted due to a     corruption problem or because the video used features your browser did not support." Object { code: 3, message: "The video playback was aborted due to a corruption problem or because the video used features your browser did not support." }

Em outros navegadores, ele está funcionando perfeitamente. Este é o meu comando ffmpeg convert:

ffmpeg -i {input} -b 5500k -minrate 5500k -maxrate 5500k -bufsize 5500k -ab 384k -vcodec libx264 -acodec aac -strict -2 -ac 2 -ar 96000 -s 1280x720 -y {output}

Alguém pode me dizer por que os vídeos não são reproduzidos no Firefox?

O suporte a H.264 no Firefox depende do sistema operacional. De acordo com aqui , este é o suporte da plataforma:

Platform        Gecko (Firefox) version
Windows 7+      21.0
Windows Vista   22.0
Android         20.0
Firefox OS      15.0
Linux           26.0 (relies on GStreamer codecs being installed)
OS X 10.7       Not yet

[...] Since H.264 is currently not a royalty free format, it is unfit for the open web platform, according to Mozilla, Google and Opera. However, since royalty free formats are not supported by Internet Explorer and Safari, Mozilla has decided to support the format anyway [...]

Firefox/Firefox for Android/Firefox OS supports the format in some cases, but only when a third-party decoder is available, and the device hardware can handle the profile used to encode the MP4.
