Getting just 10 fragments from MPD

[vidownlod]

Hi All,

I know that I'm almost there... so far and so close at the same time .
I'm trying to get the manifest from the following mpd: https://dvr-d-01-dynmedia-ea.akamaized.net/Content/DASH/LLCU/92177b25-a6cd-4eae-ad44-c...3/manifest.mpd

yt-dlp --force-ipv4 --allow-u --downloader aria2c -f bv,ba "https://dvr-d-01-dynmedia-ea.akamaized.net/Content/DASH/LLCU/92177b25-a6cd-4eae-ad44-c8810db8e573/manifest.mpd"

This is the output I got from that:

It should be a 2h stream, but its just 3MB... When I was finally able to decrypt it I could see that they were just 1 or 2 seconds of the beggining of the video.
I would really appreciate if someone could help here, as I couldn't find any solution to this.

Hello All,

After trying several things I noticed what was wrong and I was able to solve this, so I'm going to share with you what happened.

I run this command:

yt-dlp --force-ipv4 --allow-u --downloader aria2c --list-formats "https://dvr-d-01-dynmedia-ea.akamaized.net/Content/DASH/LLCU/92177b25-a6cd-4eae-ad44-c8810db8e573/manifest.mpd"

Basically the --list-formats will show all available media in different resolutions:

As you can see, there are four different mp4 files per each resolution, where three out of those four were videos that lasted a second. Same thing happens with the audio. So what I did was to download one by one until I got the "real" one, which was stream_7-2 in this case:

yt-dlp --force-ipv4 --allow-u --downloader aria2c -f stream_7-2 "https://dvr-d-01-dynmedia-ea.akamaized.net/Content/DASH/LLCU/f713c730-ee47-44d0-b1ce-2c693ddc471e/manifest.mpd"

With the "-f" argument you can specify which audio/video ID you want to download. Then I downloaded the audio file:

yt-dlp --force-ipv4 --allow-u --downloader aria2c -f stream_9-2 "https://dvr-d-01-dynmedia-ea.akamaized.net/Content/DASH/LLCU/f713c730-ee47-44d0-b1ce-2c693ddc471e/manifest.mpd"

Hope this helps someone!

N_m3u8DL-RE only shows one 1080p stream, seeming able to discern the right one, so you might want to use that next time (since you're using --allow-u)
