Which camera do you use?

jdfalk commented 2 years ago

Same here. I am using a Razor Kiyo Pro.

I've tried: ustreamer -s 0.0.0.0 -p 10008 -d /dev/v4l/by-id/usb-Razer_Inc_Razer_Kiyo_Pro-video-index0 -f 60 -m MJPEG -q 100 -c HW -n -- and every variation of this, leaving off -c -q -n ustreamer -s 0.0.0.0 -p 10008 -d /dev/v4l/by-id/usb-Razer_Inc_Razer_Kiyo_Pro-video-index0 -f 30 -m YUYV ustreamer -s 0.0.0.0 -p 10008 -d /dev/v4l/by-id/usb-Razer_Inc_Razer_Kiyo_Pro-video-index0 -f 30 -m JPEG

Same issue here with a Logitech Brio 4K, similar to the Razor camera Tried many options, including increasing device timeout -m mjpeg / MJPEG. The strange part is that ffmpeg and stream also fail.

A driver issue maybe?

charlesrg commented 2 years ago

Sure, it's a problem on the SOC side. After moving from the USB3 to the USB2 port it worked. Not sure if others tried this. I posted the streamer and ffmpeg so others could try before blaming on ustreamer directly.

jdfalk commented 2 years ago

Well that's incredibly frustrating as I got it explicitly for it's USB 3 capabilities as I'm currently flooding the usb2 bus when I use it. Guess I'm just going to have to setup a pi to host this single camera. Thanks anyways I appreciate you looking into it. If you happen to know any USB3 cameras that do work well with ustreamer I'd appreciate the info. Thanks again.

mdevaev commented 2 years ago

I think you should report about this problem to the kernel/drvier developers. Just demonstrate that ffmpeg is not working too and they will fix it.

Ustreamer just implements V4L2 API so if it's not working, this is a fault of V4L2 subsystem. I can't fix it anyway.
