I want use Raspberry Pi with my webcam, but confronted with errors.
Camshot says "streaming_on (VIDIOC_STREAMON): Protocol error"
Some apps (if i use LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so") says "libv4l2: error turning on stream: Protocol error"
Motion in setup mode says:
$this->bbcode_second_pass_code('', '[1] Retrying until successful connection with camera

ffmpeg from sources also dont want work.
Webcam: Genius iLook 1321 V2. Driver - uvcvideo, automatically loaded.
I try with different webcam (Creative Chat IM), but faced with the same error.
Once I was able to get video from webcam. I use ffmpeg-legacy. But there was a low FPS and resolution, setting ignored.
