Thanks for the clue, video0 at uvideo0 is detected again
(dmesg below; NB: a different macbook with the same symptom).
video(1) crashes though, after a few seconds of a black window:
video: ioctl VIDIOC_DQBUF: Invalid argument.
Looking at ktrace, I just spot
27453 video CALL ioctl(4,VIDIOC_DQBUF,0x7f7ffffd96b8)
27453 video RET ioctl -1 errno 22 Invalid argument
(I can send the whole trace if someone cares.)
'video -g -o video.out' does not crash,
but just sits there, producing empty output,
and does not exit on `q', needs to be killed.
I have no idea why one crashes with VIDIOC_DQBUF
and the other doesn't. Nothing in the postsequent commits
(i.e. after the 1.203 which I reversed) seems to touch that.
What else should I test?
