#ffmpeg twitter: I'm trying to stream some video from stdin to a v4l2 sink, and I'm using
ffmpeg -i - -vcodec rawvideo -pix_fmt yuvj420p -threads 0 -f v4l2 /dev/video0
which works and all, but only at 640x424. I can't find a highres pix_fmt setting tho. what am i doing wrong?
pix_fmt is the colorspace encoding, nothing to do with resolution, it's possible the v4l2 device exposes multiple video streams at different resolutions. can you ffprobe it?

i think you just need to specify -video_size 1920x1080

Hmm, no that still outputs at the low resolution :(
