Media sections in answer do not match offer #5

Closed markblumenau closed 1 year ago

markblumenau commented 2 years ago

Hello! Trying to run the example code I get the following error from aiortc: ValueError: Media sections in answer do not match offer Not sure what exactly causes this problem, but maybe it is possible to find what is wrong. Thanks in advance!

I ran into the same issue, which might not be one for you anymore. I came across this, when I subscribed to an audio stream, unsubscribed and later subscribed to a video stream. I could narrow down this to some point, but it seems, that the consumer joins a stale RTP stream, that's why it forms an answer, which doesn't match the offered media...

But I couldn't solve this. If I always stick with the same media type, that problem doesn't happen

Oh, a second after my first post I think I found the answer. The reason is the attempt to recycle some old "closedMediaSections".

See, if you can comment 170 to 173 and if this solves your problem.

Thanks! However, it has been a while since I moved from that project, so I guess it's best to close this issue.

May I ask what you did choose in replacement?

markblumenau commented 1 year ago

In my case Jitsi with some minor changes worked just fine

So you dropped MediaSoup, I guess? I'm pretty happy with that (replaced Kurento Media Server). Having clients for Web, Android and now for Python. Thanks for the details. Have a nice weekend.

BTW: This lib is pretty good, though

Yep, dropped mediasoup. This lib is good, that's true. Have a nice weekend.
