I can only find the audio mpd link in this video, help?

[Ninjachado]

Hi everyone. First post, please be gentle.

So I recently got into the whole youtube-dl business. I'm on a Mac (using High Sierra) and so I used macports to get youtube-dl on my machine. And it is working great! I've gotten a few videos to download just fine, so I know my youtube-dl is working normally.

Normally, however, I would use Stream Detector on Firefox to get the mpds and download them with the software. But I'm trying to get this specific show, "Hoogvliegers" from either NPOStart OR Stan.com.au. I can provide links to both of those here:

Stan is a pay service based in Australia, so you might not be able to access it.
Website:

https://play.stan.com.au/programs/2954081/play

When I use stream detector, I get the mpd:
MPD:

https://api.stan.com.au/manifest/v1/dash/web.mpd?url=https%3A%2F%2F707-stan.akamaized.net%2F07%2Fdash%2Flive%2F2954081A-1%2Fsd%2Fsdr%2Fmaster_h264-6a03cd15.mpd

And this MPD seems to work fine, but I only get an audio recording of the episode. It is the full episode's audio, but there's no video.


NPO start, however, is completely free to access. We might have better luck pulling it from here. When I stream detect, I get the following mpd:

This MPD returns an error right away: "ERROR: No video formats found; please report this issue on https://yt-dl.org/bug . Make sure you are using the latest version; see https://yt-dl.org/update on how to update. Be sure to call youtube-dl with the --verbose flag and include its complete output."
I have run all the updates and upgrades and it says there are no issues.


In browsing the forum, I see a lot of people mentioning encryption, and mp4decrypt, but I don't know how to find the encryption key, and also yt-dl never prompts me to input a key for decryption, so if that's the issue, I'd love some guidance.

TL;DR Stream Detector is ONLY finding the mpd that leads to the audio, or possibly, when I'm putting the mpd into yt-dl, it's only downloading the audio half, not the video half. I need help understanding what I'm missing.

it's better to use yt-dlp instead yt-dl. more feature. download this:

https://www.videohelp.com/download/yt-dlp_macos.zip

your first link need a fresh mpd and work fine. when add -F you have all list of available formats

this is an example with yt-dl (audio only):

yt-dl -F https://api.stan.com.au/manifest/v1/dash/web.mpd?url=https%3A%2F%2F707-stan.akamaized.net%2F07%2Fdash%2Flive%2F2954081A-1%2Fsd%2Fsdr%2Fmaster_h264-6a03cd15.mpd

this is the same but with yt-dlp

yt-dlp --allow-u -F https://api.stan.com.au/manifest/v1/dash/web.mpd?url=https%3A%2F%2F707-stan.akamaized.net%2F07%2Fdash%2Flive%2F2954081A-1%2Fsd%2Fsdr%2Fmaster_h264-6a03cd15.mpd

same for your second link (now is expired, need fresh mpd):

yt-dlp --allow-u -F https://start-player.npo.nl https://nl-ams-p14-am5.cdn.streamgate.nl/eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJleHAiOjE2NDEyODMzODcsInVyaSI6Ilwvdm9kXC9ucG9cL3VzcFwvVEVTVFwvbnBvXC9kYXNoX2NlbmNcL1ZQV09OXzEyOTA1NzZcL1ZQV09OXzEyOTA1NzZfdjE2MzI5MDY0ODcuaXNtIiwiY2xpZW50X2lwIjoiNS45MC4yLjEyOCIsInZpZXdlciI6ImNkMGYwOTk3NTEzOGY3M2NjNjg1YjA4OTlhMDM2YTQ1OGNhNDU0NmYiLCJyaWQiOiIzYmQxNzdhIn0.rFol5BmIwhzNk69xDWWk0rNGe5wQih6LNGOasskIkEM/vod/npo/usp/TEST/npo/dash_cenc/VPWON_1290576/VPWON_1290576_v1632906487.ism/stream.mpd

when you choose your format use (example only for first link):

yt-dlp --allow-u -f video_avc_360000 https://api.stan.com.au/manifest/v1/dash/web.mpd?url=https%3A%2F%2F707-stan.akamaized.net%2F07%2Fdash%2Flive%2F2954081A-1%2Fsd%2Fsdr%2Fmaster_h264-6a03cd15.mpd
