Help with ffmpeg and mpd please

[Chris91]

Hi. I am able to connect to a mpd server with ffmpeg using the correct header.
Now I am connected I am getting this error, over and over...

[http @ 00000285f73f2780] HTTP error 400 Bad Request
[dash @ 00000285f73db400] Failed to open fragment of playlist
Failed to parse format-tag beginning with %08x$.m4s. Expected either a closing '$' character or a format-string like '%0[width]d', where width must be a single digit

Does anyone know what this means?

Here is the command I am using

ffmpeg -headers "Host: *hidden*" -i "*hidden*.mpd" -c copy -f mpegts pipe:

I have tried adding the -re option, but that didn't do anything.

Any help is apreciated,

Quote the original page URL then.........or no one can help.

Plus your ffmpeg 'command' looks like garbage to me.

And to DL an mpd, ffmpeg would be in the list of possibilities, but not the favourite to get the job done.

Here is the site https://freefeds.com/video/67196/Discovery-Channel:US-TV-Channels.html

Maybe it is "garbage" but I am having success with other sites that use m3u links with a similar command.
I am not actually trying to download streams in the regular sense... I have created a little python app that finds the source stream on a web page and then streams back the video.

Thanks.

EDIT: It doesn't have to be with ffmpeg, but it would need to be with a command line utility that is available on linux and capeable of piping the output.

You will not download Live MPEG-DASH Stream.

If I run with debugging enabled I can see this...

Surely the "$Number%08x$" part is incorrect? Shouldn't that be, for example...

Are the key looking strings in the manifest not the ones needed to decrypt the stream?

Unfortunately, no. You need a license server url to decrypt in real time, but ffmpeg doesn't support that.

[Chris91]

Are there any utilities that do support that?

[lfer94]

I'm not sure. Or at least I don't know any.

[Sviests]

Are there any utilities that do support that?

No. License url is only for realtime playback in a browser using dash.js , to play a file locally on e.g. desktop,you will need to obtain decryption key.
