These are the two input files, I want to mux using ffmpeg.
- input.mkv
- input.srt
'input.mkv' has the following streams
- Stream 0:0 video
- Stream 0:1 audio
- Stream 0:2 subtitle (ass)
- Stream 0:3 attachment ttf (font)
I want all streams of 'input.mkv' and also 'input.srt' as default subtitle stream in 'output.mkv'
Note: I know I can use 'mkvmerge' but I need 'ffmpeg' commands.
