  • Convert set of PNGs into rawvideo .raw FFMPEG

    13 août 2020, par Wire

    Recently, I have been trying to modify the boot animation of a little robot. It is a .raw file and it contains every RGB565 frame one after the other. I have been able to get all of the frames using

    


    ffmpeg -f rawvideo  -pixel_format rgb565 -video_size 184x96 -framerate 10 -i "boot_anim.raw" -r 1/1 boot_anim%02d.png

    


    But if I try to repack it with

    


    ffmpeg -i boot_anim%02d.png -f rawvideo -pix_fmt rgb565 -framerate 10 -video_size 184x96 -r 1/1 "boot_anim.raw"

    


    it only puts in the first two frames and nothing else. I have also tried libx264 and putting in vcodecs manually. Same result. I'm new to ffmpeg and Linux overall.

    


    Here is the full output :

  • ffmpeg can not open video file while PotPlayer and VLCPlayer can

    13 décembre 2020, par popova-ksiusha912

    Win10

    


    Video file(21.83MB) :https://www.mediafire.com/file/7b7w8ssio32qo2p/sample.flv/file

    


    Pot Player and VLC Player can open this file without any problem.

    


    But ffmpeg,ffplay,ffprobe can not open it.

    


    Is there any way to make ffmpeg recognize this video file ?
