Download video with multiple audio tracks using yt-dlp

[Pavel_47]

Hello,
Is it possible to download video with multiple audio streams and then merge it with video.
For example, if video has ENGLISH and FRENCH, can they be downloaded together in single yt-dlp request, then merged with video.
Thanks

Yes, read the manual. Use the -f flag to select the audio streams

yt-dlp --allow-u -f <audio track> -f <otheraudio id> -f <video id> -o <name of download> <mpd.url>

Hello Sorenb,
Did you understand my question ?
I asked to select TWO audiotracks, NOT just ONE track.
Sincerely,

did you read the manual though?

Did you not understand my answer? Pay attention, I mentioned a selection flag and output filename flag. Think it through, and read the damn manual

[Pavel_47]

I had read the manual and couldn't find how to capture 2 audio streams.
Tried 2 options:

(1) using --audio-multistreams
(2) specifying 2 audiostreams after -F

Doesn't work in both cases - only one audiotrack is kept.
Sincerely

It's going to grab the streams individually no matter what you wish. So, script it to grab one audio then the other. Or use n-m3u8

 -f "audioID1+audioID2+videoID" --audio-multistreams

[Pavel_47]

 -f "audioID1+audioID2+videoID" --audio-multistreams

The Best !!!
Thanks !

I had a warning message because of option "--allowed-u" and audio files were downloaded separately. This is the code used:

yt-dlp  --allow-u  -f "audioID1+audioID2+videoID"  --audio-multistreams  -o  <name> <mpd url>

Is there an option to skip the warning? I really want to get video+audios downloaded in the same file. Thanks.

Yes It's normal

Decrypt audio and video separately with your key.

Merge them with ffmpeg.

ffmpeg -i videodecrypt.mp4 -i audiodecrypt.m4a -c copy new.mp4

Ok, thank you for your reply.

This is "a little bit longer" way...

1- List the content of MPD:

yt-dlp --list-formats --allow-unplayable-formats mpdlink

All video and audio formats will be listed with their special Stream IDs (changes on each site)


2- Write down the Stream IDs for audio/video files to be downloaded:

yt-dlp -f streamID --allow-unplayable-formats mpdlink


3- After all downloads and decryptions, merge the video and audio files with MKVToolnix.


If you also want subtitles (if available):

yt-dlp --skip-download --write-subs --sub-langs "en, fr," --allow-unplayable-formats mpdlink


You can also use "Encrypted Video Downloader" batch file, but you will have to download the audio files seperately again. Only one audio and one video will be downloaded, decrypted and merged. You will need yt-dlp, mp4decrypt, aria2c, and ffmpeg in the same folder.
