ffmpeg setting not working for x264 compatibility in television I'm having some files in MKV format (x264). Some files work flawlessly in my non-smart TV, but others are not even opened at all or crashing.

I tried the following command in FFmpeg to convert it to the mp4 format since it has wide platform compatibility in TVs.

ffmpeg -i input.mkv out.mp4


But its still not playing in my TV, please help me with the correct ffmpeg parameters.
notworking.mkv is 10-bit H.264 (yuv420p10le). I'm guessing the TV can't play that. You'll have to re-encode to the more common yuv420p for the TV to be able to play it. Basic example:

ffmpeg -i notworking.mkv -map 0 -c copy -c:v libx264 -vf format=yuv420p output.mkv
