Audio not succesfully intergraded whit video

[Timtta]

this is cause there are 16 video segments
16 subtitle segments
and
17 audio segments

[emarsden]

I don't think I've ever seen that. It's probably allowed, if the audio segments are shorten than the video segments and the total audio duration is the same as the total video duration, but I expect the muxers would work in that situation.

You can try with another muxer helper (see the --muxer-preference commandline argument).

If you can share the MPD URL or MPD contents I can take a look.

[Timtta]

whell i can share it but i cant asure you you can directly watch the livestream (geo-restricted)

error: a value is required for '--muxer-preference CONTAINER:ORDERING' but none was supplied
sorry that im dumb what what needs to be in CONTAINER and ORDENING

[emarsden]

Make sure you have mkvmerge (from the MKVToolnix suite) installed and try

--muxer-preference mkv:mkvmerge -o mydownload.mkv

(this will download to a file called mydownload.mkv in Matroska format).

I can't currently test that manifest.

[Timtta]

ok im now waiting for download to fetch DASH manifest

then when i opened those files manualy i notised the little delay in audio video

[emarsden]

You don't seem to have installed mkvmerge, or at least it's not in your PATH. But that's probably not the real problem if you see a delay when loading the two streams manually, I'll try to access this MPD.

[Timtta]

thanks the delay is the problem like you first see a big BOOM! schreen and then 1 sec later you hear BOOM! like that

[emarsden]

This is a "live" / "dynamic" manifest, and dash-mpd-rs doesn't currently have very good support for downloading content from these. In fact it hardly downloads any segments when I tried the channel you showed. I might try to improve that support one day, but probably not soon. You might have more luck with VLC.

[Timtta]

whell for me it allready whould help if a feature exists that whould (mayby expirimental) allow you to manualy set a delay of segments from audio, video or subtitles
PS: im using vlc and there are free vpn's to Netherlands that work
on mobile you can get a lad an pc not that many but still some

[Timtta]

i got it convertering directly with ffmpeg was sollution
