Unable to receive frame messages with ffmpeg

[blauter]

I have new Reolink RLC-420 with latest firmware added via onvif using ffmpeg passthrough (audio enable) with major smearing. Searching for this does return a lot of people experiencing similar issue with this camera so I tried a bunch of ideas offered including disabling all enhancements, dropping to 1080p, dropped framerate and throughput, tried different encoding profiles, all with no major improvement. Seems to happen more at night.

Maybe below is just related to this cameras poor performance with ffmpeg passthrough but any other suggestions? Based on the code where it seems this log entry is coming from, I am hitting hw acceleration. Is there any way to disable it just as a test? I didnt see option in UI and didnt see command line option either. I thought of maybe compiling a test version of ffmpeg without hardware acceleration just as a test but does anyone think its worth the trouble?

Unless you are on a raspberry pi using my custom ffmpeg builds, you are not using hw acceleration.

Those messages mean that ffmpeg has not been able to receive a full image yet.
