Error messages related to HEVC transcoding filling log

polyventures · June 3, 2025, 12:00am

I am using a M1 mac mini as a my DVR server hardware and have enabled HEVC for remote transcoding. Sources are HDHomeRun Primes and OTA duos. These error messages are totally filling my server log. Is there a way to suppress them or make a software change so they are not reported in the first place?

Your logs show ch54.. is that from one of the PRIMEs? Is it only happening for channels from that source?

If you view that channel without transcoding what does Show Stats say for the video codec?

The channel is from one of my two primes. If I tune it locally with an appletv the codec shown with "show stats" turned on is "mpeg2video"

The programming is HGTV

This issue is not exclusive to HEVC -- I turned it off and the issue remains with h.264 transcoding. The logs are saturated with these messages. Can they be suppressed somehow?
