 Summary of the bug:
 As of kernel 5.15.61+, HW accelerated decoding of H.264 via the
 h264_v4l2m2m option no longer returns frames (software decoding works
 fine) There is a patch at https://github.com/jc-kynesim/rpi-
 ffmpeg/commits/test/4.3.4/rpi_main but it doesn't target the latest
 versions, and the author appears to be AWOL after having promised to
 submit it upstream.

 This issue was identified on the Frigate project, as running Frigate on a
 Raspberry Pi 4 is quite a common use case. I've confirmed the patched
 4.3.4 version resolves the issue, but a proper fix requires this to be
 merged upstream.
