[Live-devel] Always dropping the first frame?

[Alex Agranovsky]

Server-side: using stock live555MediaServer running on macOS.

Client-side:

- The problem occurs regardless of transport (both TCP and UDP)
- The problem is seen with our code using RTSPClient API
- The problem doesn't occur with testRTSPClient. Currently looking at 
possible implementation differences (not finding a whole lot, yet)

Clearly, all the packets that comprise the first frame are received over 
the wire (I check the size of the discarded packets, and it adds up to 
the total of the first frame size). However, the content of the first 
packet is different, somehow. Not sure what could cause it -- still looking.
