I have a image sensor that streams 640x480 in RAW8 format. A USB controller is receiving this data, packing two pixels of 8-bits each and sending to USB as a 16-bits per pixel YUV422 format (this is because currently UVC does not support RAW8 format).

I was checking if I can use ffmpeg to receive the UVC stream and decode it as RAW8 video.

Has anyone tried this before?

With

ffmpeg -f video4linux2 -list_formats all -i /dev/video0

you can query all available formats and resolutions

With

ffplay -f video4linux2 -input_format raw -i /dev/video0

you can access the raw video stream of the UVC device

  • Thanks for your reply! I am using Windows and was able to stream RAW8 video by reporting the pixel_format as gray. ( I used ffmpeg -f dshow -pix_fmt gray -video_size 1280x720 -i video="UVC" -f nut - | fplay -flags low_delay - ) However, I do not see any way to stream RAW10. I am not sure which pixel_format to use in this case. Do you know? Thanks!

  • What output do -pix_fmts and -list_formats show?
