I looked at the tests and yes I can write one that fails, maybe need to extend rtspd a bit, sequence would be like:

- start N interleaved-rtp rtsp sessions using multi interface
- for all of them:
   - get the SSRC from from the SETUP response and convert to int
   - set the SSRC as INTERLEAVEDATA
   - In the interleave function compare the SSRC in the rtp payload with userdata
   - If it differs --> stop with failure
- terminate after X seconds --> success

So far it’s a bit 'random' when the mixup will occur so I hope the timing will match reality
It may take a while before I get to it, will live with the limitation in the meantime..
