Html FFmpeg转换文件在firefox上不起作用

当我使用ffmpeg转换文件并在firefox中播放视频时，会出现以下错误：

"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." }

在其他浏览器中，它工作得非常好。 这是我的ffmpeg convert命令：

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}

有人能告诉我为什么这些视频不能在firefox中播放吗？

似乎错误解释了-\video使用的功能您的浏览器不支持查看此帖子-@Coffee是的，但是哪些功能？因为这样我就可以更改命令了。@Coffee它在chrome和opera中工作，所以只有Firefox可能尝试-pix_fmt yuv420p？
