X265 log spam in home assistant core logs

Configuration
1

I’m at a loss here. My logs are being completely flooded by the following repeating block of text. nothing else around it, this is the entire thing:

This repeats approximately every 2 seconds. It does not show up in the condensed logs, only in the full logs. it’s level of “info” and I have logger set to a level of “warning” so it shouldn’t even be logging it as far as I can tell, yet here it is.
I have tried disabling every integration that has a camera, and the log spam continues, I have no idea where this is coming from, or how to stop it.

I tried asking Claude, Grok, Gemini, and ChatGPT. All of them were completely clueless on this one, they all asked me to log in to the machine and try to find this process with ps, a watch loop, proc, etc. None of those found an ffmpeg, go2rtc, stream, or other process that could cause this.

My configuration.yaml file does not contain any “camera” “stream” etc. everything camera related is gui config only.
Integrations that I have that have a camera:

  • frigate
  • moonraker
  • environment canada

additionaly on the front-end I have the custom camera card. but this message appears in the log even when no browser/app/etc is open to that dashboard.

Anyone have any ideas?

Boot HA in safe mode.
This strips all custom and apps stuff.
Is it still there?
Assuming not, begin starting apps and/or custom integrations a couple at a time until it starts.
That’s what I would do. “HEVC encoder version” tells me start with anything video related first. ffmpeg is a core integration, and could also be related.

The Environment Canada integration doesn’t use x265 (or any video encoding really) so it’s unlikely to be the culprit.

Well I proved that it was in fact related to the Frigate Integration, so I created a bug report over there: x265 HEVC encoder spamming HA core logs. · Issue #1081 · blakeblackshear/frigate-hass-integration · GitHub
Only to be told that it’s not them because it’s not tagged as frigate, so I created a bug report over at core: x265 HEVC encoder spamming HA core logs · Issue #169764 · home-assistant/core · GitHub

2 things going wrong:

  • Whatever the log message itself is complaining of (appears to be a failing attempt to transcode)
  • The fact that it’s logging “info” level messages when logger is set to “warning”.
