  • FFMpeg - Save JPGs From Stream

    14 janvier 2018, par user1149620

    I have a multicast UDP video stream. I am trying to write an FFMPEG script that will capture that to JPGs, ideally at the framerate the video is broadcast at (25fps).

    Would someone be able to help let me know the kind of command I need to do this. (I can find commands to update a single JPG, but I would like a continuous stream of JPGs to be saved).

    Thanks

  • ffmpeg - Continuously stream webcam to single .jpg file (overwrite)

    8 octobre 2016, par Germanunkol

    I have installed ffmpeg and mjpeg-streamer. The latter reads a .jpg file from /tmp/stream and outputs it via http onto a website, so I can stream whatever is in that folder through a web browser.

    I wrote a bash script that continuously captures a frame from the webcam and puts it in /tmp/stream :

    while true
    
do
    
    ffmpeg -f video4linux2 -i /dev/v4l/by-id/usb-Microsoft_Microsoft_LifeCam_VX-5000-video-index0 -vframes 1 /tmp/stream/pic.jpg
    
done

    This works great, but is very slow ( 1 fps). In the hopes of speeding it up, I want to use a single ffmpeg command which continuously updates the .jpg at, let’s say 10 fps. What I tried was the following :

    ffmpeg -f video4linux2 -r 10 -i /dev/v4l/by-id/usb-Microsoft_Microsoft_LifeCam_VX-5000-video-index0 /tmp/stream/pic.jpg

    However this - understandably - results in the error message :

    [image2 @ 0x1f6c0c0] Could not get frame filename number 2 from pattern '/tmp/stream/pic.jpg'
    
av_interleaved_write_frame(): Input/output error

    ...because the output pattern is bad for a continuous stream of images.

    Is it possible to stream to just one jpg with ffmpeg ?

    Thanks...
