• Inappropriate ioctl for device in zoneminder - zmc_dvideo0

  9 juin 2024, par Adam

  I recently needed to rebuild my zoneminder local camera system, running on an RPi. I switched OS from Debian to Ubuntu and now I'm struggling to get video4linux to decode the video input. The result is either a black or green screen depending on the compression palette I select.

  


  I'm using /dev/video0 as my input.

  


  v4l2-ctl --list-devices

unicam (platform:fe801000.csi):
        /dev/video0
        /dev/media3


  


  In the logs I'm getting :

  


  zmc_dvideo0 10907   ERR Unable to query control: Inappropriate ioctl for device 


  


  I don't understand the function of the /dev/media3 device, presumably created by the bcm2835-v4l2 module. This site suggests that /dev/video0 needs to extract the ioctl from or link in some way to /dev/media3. Perhaps a red herring.

  


  If I select /dev/media3 as the source, I get :

  


  : FAT [zmc_dmedia3] [Failed to query video device: Inappropriate ioctl for device]
: ERR ['zmc -d /dev/media3' exited abnormally, exit status 255]


  


  I'm using

  


  

  • PAL60 encoding

  


  • YUV422p compression

  


  • 1280 x 720 Capture Resolution

  Using ffmpeg from the cli, I get a similar output, resulting in a green display. This happens both with and without the hardware acceleration flag.

  


  sudo -u www-data ffmpeg -f v4l2 -pix_fmt yuyv422 -framerate 30 -video_size 1280x720 -i /dev/video0 -codec:v h264_v4l2m2m video0_out.mp4


  


  I've set debug to 6 in the ZM options - Any clues on troublshooting steps I can take to further understand why the camera stream is not being shown and how to fix it ?

• Generation thumbnail from video using ffmpeg [closed]

  23 avril 2024, par godvlpr

  Try to create thumbnail from video using ffmpeg
This command work perfectly :

  


  ffmpeg -i test.mp4 -ss 00:00:00 -vframes 1 thumbnail.jpg

  


  But I need to push video to ffmpeg from stdin, and find solution with pipe :

  


  cat test.mp4 | ffmpeg -f mp4 -i pipe:0  -ss 00:00:00 -vframes 1 thumbnail.jpg

  


  But it's not work for me. Error :

  Tried on macos and ubuntu. What can be wrong here and how to fix this issue ? Maybe exists other solutions without pipes, or something else..
