getting error whenever trying to stream through raspberry pi

ERROR:root:V4L2Camera: can't read SPS and PPS from the first frame

Does your camera support h264 format? You can check with: $ v4l2-ctl --list-formats

[yogii786]

here I attached screenshot of listed formats could you please check and let me know sugggested camera which support H264 format?

[yogii786]

using usb camera IMX291

[soyersoyer]

It works with the pi camera boards (with the old camera stack) or any usb uvc camera which supports the h264 format. You can find some here: https://en.everybodywiki.com/List_of_cameras_with_onboard_video_compression

I have already started working on encoding the YUYV format with the V4L2 m2m encoder on the pi. Stay tuned!

Not sure if related, but I am getting this:

Traceback (most recent call last): File "/home/pi/fmp4streamer/fmp4streamer.py", line 271, in camera = V4L2Camera(device, dict(config.items(device))) File "/home/pi/fmp4streamer/v4l2camera.py", line 35, in init self.init_fps(int(params.get('fps'))) File "/home/pi/fmp4streamer/v4l2camera.py", line 66, in init_fps ioctl(self.fd, v4l2.VIDIOC_S_PARM, parm) OSError: [Errno 25] Inappropriate ioctl for device

I can stream fine using gst-launch-1.0.

After removing a couple of ioctl calls I am left with the same error:

ERROR:root:V4L2Camera: can't read SPS and PPS from the first frame

I would also be interested on the YUYV format.

Hi @fcoury could you please share your Gstreamer pipeline so that I can use that

[yogii786]

Imx291 usb camera supports H264 format hence I checked by printing sps and pps there values are 2 and 2 respectively

[soyersoyer]

Try the 3.1.0 version and read the Readme for the configuration.

[soyersoyer]

@yogii786 Please try the v3.2.0 with the capture_format = MJPGH264 configuration option.

Feel free to open, if you have any other questions.
