Describe the problem you are having

New error in 0.15 dev.

I have a camera mounted upside down with no ability to rotate the image in-camera, so I use ffmpeg to rotate the image, once for recording, and once with a downsized stream for detection.

Since upgrading I get continuous (every 4s) errors from go2rtc on the rotated and downsized feed:

2024-10-21 16:56:26.247967946 [vf#0:0 @ 0x5573ded67380] Error while filtering: Cannot allocate memory

There's 32GB on this machine and 16GB limit on the Frigate container, which it isn't close to. It's an Intel I7-10700t using the built-in GPU so possibly there is a shared memory limit yet, but I can't get memory stats from the iGPU.

I did have a go at making the downsized feed base itself off the rotated feed (to avoid two sets of rotations) but couldn't get that to work.

This is most likely just related to using a newer ffmpeg, you could try some different things:

1. add manual input args to go2rtc to set the filter_threads 1 -filter_complex_threads 1 and see if that helps
2. set the path to 5.0 so it uses the same ffmpeg build as previous versions of frigate
3. try a different ffmpeg 7.0 build and see if the issue persists

Thanks for the fast response. I can confirm 2) fixes it; will try 1) and 3) at some point as well.
