[Live-devel] waiting for SPS/PPS

Mon Jul 6 11:38:51 PDT 2020

Ok, so I am now using openRTSP to receive the video, and it is creating the
video file ok, but when I actually go to play it.. no video plays. I tried
VLC and MPV, is there an official video player you'd like me to use for
testing playing them?

I'm using a new version of live555, is it possible there is some bug newly
introduced? I could've sworn this was working before.. though it's
certainly possible I'm doing something different.

Thanks again Ross

I see these errors in VLC's log:
