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

Don't forget to check supported formats and 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?

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.
