This happens since version zoneminder:amd64 (1.37.61~20240611171544-jammy).
A downgrade to version zoneminder=1.37.61~20240611.106-jammy fixes the problem.

The crash does only happen for 2 of my 5 cameras. The 2 are very old Supra IPC 10A cams that use MJPEG:

Input #0, mpjpeg, from 'http://192.168.0.244/videostream.cgi?us ... n&pwd=1234':
Duration: N/A, bitrate: N/A
Stream #0:0: Video: mjpeg (Baseline), yuvj422p(pc, bt470bg/unknown/unknown), 640x480, 25 tbr, 25 tbn, 25 tbc

I believe I fixed this on the 28th. Please confirm that it is still affecting you with latest build.
