Hey all,

New here so sorry if this is in the wrong section.

I've had some success streaming screen to RTSP but it's showing quite a few errors and there is considerable lag. Wondering if anyone else has tried this and managed to find the best parameters to fine tune the encoder?

The command I use is:
VLC -I dummy screen:// :screen-fps=10 :screen-caching 100 --sout=#transcode{vcodec=h264,vb=5000,fps=10}:duplicate{dst=rtp{sdp=rtsp://192.168.1.200:8080/},dst=display}

The errors being shown are:

[0000000002bb49d0] avcodec decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)
[h264 @ 00000000047737e0] co located POCs unavailable
[h264 @ 0000000004770e60] mmco: unref short failure
[h264 @ 00000000047712c0] co located POCs unavailable

Ideally I'd like a higher fps but I reduced this to see if that would reduce the errors (it didn't).

Thanks in advance.

Hi,

For the sake of testing, does it works without the duplicate module after waiting a little ? Something like this :
