  • why ffmpeg only combines first 390 images when combining very large amount ( about 9k) images into video ?

    4 juillet 2021, par Siwei

    I have a VCD, and I split it into nearly 10,000 images, named like :

    


    $ ls tmp_enlarged_image_folder

vcd3_00000001.png
vcd3_00000002.png
vcd3_00000003.png
vcd3_00000004.png
...
vcd3_00089998.png
vcd3_00089999.png
vcd3_00090000.png


    


    and the following command doen't work for me :

    


    ffmpeg -loglevel trace -f image2 -r 25 -pattern_type sequence -i 'tmp_enlarged_image_folder/vcd3-%08d.png' -vcodec libx264 test.mp4

  • ffmpeg performance on raspberry pi

    20 août 2021, par Rudi

    I'm running ffmpeg on a rasperry pi 4. I'm capturing the signal of an usb device.

    


    ffprobes output is :

Input #0, video4linux2,v4l2, from '/dev/video0':
  Duration: N/A, start: 1230.660915, bitrate: 1990656 kb/s
    Stream #0:0: Video: rawvideo (YUY2 / 0x32595559), yuyv422, 1920x1080, 1990656 kb/s, 60 fps, 60 tbr, 1000k tbn, 1000k tbc


    


    the ffmpeg call i'm using is :

    


    bin/ffmpeg -loglevel quiet -re -f v4l2 -i /dev/video0 -tune zerolatency -preset ultrafast -pix_fmt yuv420p out.mkv


    


    put the framerate starts at around 20 and increases slowly to 36. Also when reviewing the output videos i feel like i see a bit of a framedrop so the video is not as smooth as the input.

    


    Is this due to a lack of power of the raspberry or are there any tweaks i could use to improve performance ? I don't care about the output format, framerate or resolution

    


    thank you very much
