Let me explain...
There are also various flags to the err_detect option [1] which could be tried; and -max_error_rate, but that only lets you set a threshold for detection after the fact [2]. I haven't seen a way to get ffmpeg to exit on a specific error, or to ignore a specific error. If the monotonic DTS error is i) the sole other error reported and ii) you definitely don't care about it: it would be possible to modify the source and recompile ffmpeg to stop it doing so. I am no expert in either C or the ffmpeg source so I would welcome correction, but the conditional on line 188 of ffmpeg_mux.c [3] looks like the one you would need to remove. Alternatively, you could go the other way: find "corrupt decoded frame" and add a line there to cause ffmpeg to always exit if so.
