In case your question is related to a piece of media:

video from camera cant cant provide

Don't forget to check supported formats and devices nothing to do with devices

I have the same issue. Why we can't ignore the field "timing"? Why this field is necessary if in original sdp timing may not exist?

I also met what to do

[NicolasGodfather]

We waiting for expert answers!

[claincly]

If you look at RFC2327 Section 6, those fields are mandatory. That said, we don't use these fields in the RTSP logic, so it's safe to remove the check.

We'll have a change to remove this check.

Thanks! Will be perfect if you remove this check.
