So I found that I can set parameters through the AVDictionary, however I
don't know which entry to use in order to modify the udp buffer size.
Anyone knows if this is how to set this parameter?

Hi there,

I'm using very high resolution cameras via rtsp. Initially I had several
broken frames and an unstable connection. I ended up finding out that
this is due the UDP max buffer size.
By changing libavformat/udp.c and setting UDP_MAX_PKT_SIZE to be a lot
bigger. This did solve the issue completely and everything works just fine.
However I know there must be some way to do this via the API. In the
link #2 above I read:

And I'm not sure what that means. There must be some way to access these
parameters once I get my AVCodecCtx after opening the stream. Any idea how?
Thanks!
