Description

Hey there, well I was trying to download some videos being run on azure media player. Well what I do is open chrome debugger and find the manifest link and input it in the yt-dl executable. Some links work, others return no video formats found.

For example:

• When I input this in yt-dl executable, it returns no video formats found:

D:\Azure\youtube-dl.exe --merge-output-format mp4 "https://elvideoservices-aase.streaming.media.azure.net/0d9798d8-6096-431a-af95-81117aa5ea6b/MDcatOrientationofSubjectsFinal.ism/manifest(format=mpd-time-csf)"

• When I input this in yt-dl executable, it starts downloading 1920x1080 video for me

D:\Azure\youtube-dl.exe --merge-output-format mp4 "https://elvideoservices-aase.streaming.media.azure.net/31865afb-2080-4ba2-a5b9-44a87711e61d/StepMDCATChemistryTest16.ism/manifest(format=mpd-time-csf)"

Now the fact is that both of these links are working and have video sources in them. It can be proved by entering these links in Azure Media Player demo by Microsoft.
Here is the link for player:

https://ampdemo.azureedge.net/azuremediaplayer.html

There, you can input both URLs and can watch both videos. Both videos have no type of encryption but it is very weird that one can be downloaded and other can't. I was looking for a solution and I want the issue to be solved, maybe through some update or something because I want to download more of these videos. Thanks. If you need I have also downloaded the manifest files of both the working URL in yt-dl and non-working one.

They are given below

I am not a programmer or a coder otherwise I would have tried my best to help you out in the solution for this. I think it can be solved by trying to code the grabber to find links in the manifest or some similar way like that.

Looking for solutions eagerly. Peace out.
