Did you try to reboot the RPi?
Just to keep this alive, here's my config: v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=YU12 -c video_bitrate=4000000,auto_exposure=0,scene_mode=8,exposure_dynamic_framerate=1,compression_quality=100 exec hkcam --min_video_bitrate=1536 --data_dir=/var/lib/hkcam/data --verbose=true
and here's the error: [video4linux2,v4l2 @ 0x21aee60] ioctl(VIDIOC_STREAMON): Operation not permitted /dev/video0: Operation not permitted video4linux2,v4l2 @ 0x170e020] ioctl(VIDIOC_G_FMT): Invalid argument /dev/video1: Invalid argument
It works correctly just changing the resolution down to 1080x720
Can this be the explanation? https://raspberrypi.stackexchange.com/questions/81589/problems-using-bcm2835-v4l2-module-w-ffmpeg
I already have gpu_mem=128
Hi, this is happening to me too. Is it possible to switch to 1920 x 1080?
I've found that with some tweaks it is possible to get to 1920 x 1080. The key that I found was necessary was to set _gpumem=256 in /boot/config.txt along with setting the width and height using v4l2-ctl before calling the hkcam executable. With the hardware offload for encoding even the pi zero has enough memory for a basic OS installation, and htop shows roughly 20% total CPU usage while outputting a stream of 1080p @ 30 fps.
Note that it is the calling Apple device that determines the output resolution. My iPad Pro requests a stream at 720p resolution. I've had to modify stream.go's calling of ffmpeg in order to force the higher resolution of 1080p, but it does work.
I'm planning to submit a pull request that will include additional command line arguments and a change in the call to ffmpeg, but I need to do some more experimentation.
Thanks Eduard!
Thanks for your work on this @edwardhughes - looking forward to your PR.
I am running the Raspberry Pi Zero. I am been messing around with the settings in the run
file to optimise this but not really having any luck. I can't get the frame rate above 5fps. Would you recommend changing anything? Also maybbe changing the pixelformat=YU12
?
v4l2-ctl --set-fmt-video=width=1280,height=720,pixelformat=YU12 -c sharpness=30,video_bitrate=30000000,auto_exposure=0,scene_mode=8,exposure_dynamic_framerate=1,compression_quality=100
exec hkcam --min_video_bitrate=1536 --data_dir=/var/lib/hkcam/data --verbose=true
Is this still an issue?
In the hkcam start script setting the resolution to 720p allows the camera to start up and work.
However setting to 1080p does not allow the camera to start.
