[Camera FFmpeg] [Predsoba] [hevc @ 0x43a1310] [error] Could not find ref with POC 34
Hi, I get this problem using China A9 camera which sends HEVC not h.264. On error picture disappear and comes back, i set force FPS to 15 and it is little better but still error comes and picture disappears. link is the same: 
-i rtsp://admin:admin@192.168.0.180:554/onvif1 as for other YooSee camera which has h.264 and is working normally.

Can you help, should I add some FFmpeg option in link ?

Thank you
