  • Take webcam picture with minimal delay [on hold]

    20 septembre 2017, par x-ray

    I would like to take a picture from a webcam and send that as an http server’s response. I know how to do the http server part, but I need a command that takes the picture and writes it to stdout. I tried this with ffmpeg :

    ffmpeg -f video4linux2 -video_size 1920x1080 -input_format yuyv422 -i /dev/video0 -f image2 -frames:v 1 -qscale:v 1 pipe:1

    This is working, the only drawback is that it takes about 3 seconds to get the picture. The delay comes from ffmpeg (not from the server/network), probably because it needs to wait for the webcam to initialize. I found that out by replacing pipe:1 with out.jpeg and running the ffmpeg command on the console.

    So now my idea is to have one ffmpeg process running all the time and stream the webcams raw video data somewhere, and then start a second ffmpeg process on each http request to get the current video frame as jpeg from that somewhere. However I do not know if it can work that way, and I do not know how to implement it. There might also be a better way for the whole task (send current picture from webcam on http request with minimal delay).

    Appreciate any help with this !
