It's very normal, e.g. for session IDs or so.

Perhaps we can expand the rtsp.c for that, as another option to AVContext?

About 2nd one, is this supported from command line?
I get "460 Only Aggregate Option Allowed" when trying the following form:
ffmpeg -i "rtsp://192.168.0.150/loadtest.sdp/trackID=1?a=1"
ffmpeg -i "rtsp://192.168.0.150/loadtest.sdp/trackID=1?a=1&tcp"
