Yes.

Let an LLM help you with the commands 👍

"Use this command to include all streams:

ffmpeg -i input.mkv -c copy -map 0 output.mp4

Explanation of the added parts:

* -map 0: This option tells ffmpeg to include all streams (video, audio, and subtitles) from the input file (indicated by '0') in the output.

Important Note about Subtitles:

* MP4 has limited support for subtitle formats compared to MKV.

* If your MKV has advanced subtitle formats (like PGS or ASS), they might not be displayed correctly in some MP4 players.

* You can convert subtitles to a more compatible format (like MOV_text) if needed, but that's a more complex command."
