  • Capturing frames from an h264 stream with gst/ffmpeg

    17 août 2016, par Yuval.Sightec

    I want to save (as jpegs) or reach the data of the frames streaming from my usb camera.
    Meaning that I want to use the h.264 hardware encoding (I running it on nvdia jetson) in order to get a sequence of compressed files (I prefer not save it on the disc and get an array, if possible).
    Can I do that ?

    So far I tried this :

    gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-h264,framerate=30/1,stream-format=byte-stream ! decodebin ! videorate ! video/x-raw,framerate=30/1 ! videoconvert ! jpegenc ! multifilesink location=img_%04d.jpg

    but I get an internal data flow error from v4l2src0 element, and an error from gst_base_src_loop() after the pipeline was set to PLAYING.

    Can anybody please help me ?

    b.t.w- It doesnt have to be neccecerly h.264 encoding, it also can be mpeg encoding or something else : I want to use the fact that it is pictures of a video, frames, in order to get smaller size frames.

    Thank you so much !

  • How to make WebM video file seekable using ffmpeg while keeping video format same ? [closed]

    4 janvier 2023, par Alok

    I downlaod video using chrome extension in WebM format but these videos are not seekable (meaning the seekbar does not work as expected).

    


    What I've tried :

    


    I have used a tool called MKclean, which can fix it by using this command :

    


    mkclean --doctype 4 --keep-cues --optimize original.webm optimized.webm


    


    How can I achieve this same result by using ffmpeg so I can make my WebM videos seekable ?
