[FFmpeg-user] convert mkv to mp4

[KoSza]

Hello,

Thank you for the tip.

It seems that attached files made some problem, and the mail was not
delivered.

The container change was done, but the file is not good.

The access rights are different from the original file, but this is the
smallest problem, I can set it easily
The end of message was:
...

And as I expected there are more problem with the new file:
- it is not DolbyVision just HDR . The goal is to see DV video, but LG does
not play MKVs as DV, only HDR... Instead it plays mp4s well.
- it is not played well by my LG with Plex,
- the audio channels are gone, I have only one

It is like I used ffmpeg - file.mkv -codec copy file.mp4 (I believe it is
better with the subs)

Is there a way to keep audio tracks also?

Thank you,
K
