we are trying to connect GoPro Hero 5 black to raspberri pi-4 using HDMI to CSI2 convertor. but we are facing a problem, like whenever we try to stream using ffmpeg or any live video software we are unable to connect the device and it give the following error
[video4linux2, v4l2 @ 0x15ce430] ioctl(VIDIOC_STREAMON):Invalid argument /dev/video0: Invalid argument
we tried
cat /dev/video0 throws the same error.
on the other hand we have the another camera which works perfectly!
Any inputs will be appreciable.
