Good day,

were the technical things (changes into standard network code) resolved in the mean time? I've the feeling that it is looking at the patch.

On https://github.com/Haivision/srt/pull/140, there is at least a PR to make a debian package for it.

I think the name is a minor problem which is solveable - this shouldn't be a blocker. What about "osrt" - adding the o for open? ;-)

Regarding the usage: Is there any other option with pure ffmpeg to stream videos over a lossy packet-based network (like the Internet) with 
UDP+fault tolerance without having the hassles of TCP, which is unusable for at least "real" live transmissions? A 1:1 solution would be enough.

Best regards,
Michael Fritscher
