I've encounetered a couple of challenges:
The 'master' mode camera won't take configuration by 'media-ctl'. Discussion thread here: viewtopic.php?t=361712
For this post, I'm having trouble with the "--circular" option in rpicam-vid. It does not appear to work for h264/libav in rpicam-vid anymore. I used this extensively on my rpi4 with libcamera-vid and it worked well.
Using this config:I run and see this:And you can see the file size is much bigger than the 1meg requested (it just continuously grows):I did a little light digging in the source for output.cpp (https://github.com/raspberrypi/rpicam-a ... output.cpp in the create it seems like if the codec is libav or h264 on rpi5, you'll never get the circular buffer?
