After Ubuntu upgrade from 16.04 то 18.04 & 20.04 i have troubles with connecting to a part of MJPEG monitors by FFMPEG.
From monitor log:
In VM clone of ZM server, saved before upgrade, i have ffmpeg -version, where everything's working fine:zmc_m19[4048090].ERR-zmc.cpp/300 [Failed to capture image from monitor 19 BD4680DRZ-186882901903 (1/1)]
