unable to decode frame at frame 0

[fips]

Hi,

for some reason my working cam stopped.

Log says:
.) Starting Capture version 1.30.4
.) Priming capture from rtsp://admin:admin@192.168.1.210:554/rtsp_live0
.) Unable to decode frame at frame 0
.) 'zmc -m 2' exited abnormally, exit status 255

in VLC the URL works fine, on Zoneminder server that command works fine too:
ffmpeg -i rtsp://admin:admin@192.168.1.210:554/rtsp_live0 ./test.avi

How can solve this problem?

EDIT:
when I execute ffmpeg -i rtsp://admin:admin@192.168.1.210:554/rtsp_live0 ./test.avi
on shell I get those messages:

Camera resolution in Zoneminder does not match camera output. Use VLC (Tools, Media Information, Codec) to check camera Display Resolution.
