mkv with --tomp4 ffmpeg options

I find that I need --ffmpeg-acodec aac --ffmpeg-movflags frag_keyframe+empty_moov+faststart to get the video to play on my chromecast.

Thanks @stevenao . This helped me play some files!

--ffmpeg-acodec mp3 also works, and I expect any codec listed at https://developers.google.com/cast/docs/media will work as well. Lots of MKV media files out there have codecs like AC3, which the Chromecast won't play.

empty_moov was the piece I was missing. Without it, the device would play audio with no video.

Yeah, had to do the same thing with stream2chromecast as well.
