Is there way to combine video and audio stream without remuxing?

[Lirk]

I want to play dash stream in old MPlayer version, without yt-dlp support. I use the "-audiofile" option for playing separate audio stream, e.g. "mplayer videostream_url -audiofile audiostream_url". But this doesn't work for MPlayer GUIs, so need to play from one file, maybe m3u8 or something else. Does m3u8 support playback video and separated audio stream? I tried to use this examples (https://datatracker.ietf.org/doc/html/rfc8216#section-8.6), but without results.

Both MPC-HC and MPC-BE can do this.

I tried it, but it worse, than MPlayer, maybe you talk about new versions, but I need to use old versions for Windows XP. Old versions of MPC-HC/BE works very slowly with network streams. The best way is to use MPlayer based players and just need solution to play separated video and audio from network streams.

Good luck finding something for Win XP!

But I use now yt-dlp with MPlayer and it works, the main problem - it works with dash streams only without GUI. Would be better to use GUI, but it doesn't support MPlayer parameters from command prompt.
