Juliusz Chroboczek 5a2dbf36b9 Signal new tracks explicitly. 2020-05-20 23:43:46 +02:00
Juliusz Chroboczek 5916028edd Split the main up loop into two threads. 
The reader and the writer now communicate through a channel and the packet
cache.  If the writer thread drops behind, we drop packets after inserting in
the packet cache, which avoids building a backlog.

Juliusz Chroboczek b26a8cad78 Label tracks explicitly. 
For now, this is only used to request screen sharing as opposed to normal
videos.  In the future, it will be used for simulcasting.
