  • Can´t convert .mp4 file to .mjpeg file with ffmpeg

    19 février 2018, par Herr HupfDohle

    I use ffmpeg to convert a .mp4 file to a .mjpeg file and I fail doing so.
    What i tried so far :
    Converting directly from .mp4 to .mjpeg with one of these :

        "ffmpeg -i input.mp4 output.mjpeg"
    
    "ffmpeg -i input.mp4 -framerate 25 output.mjpeg"

    Getting all the individual images of my video (which worked fine) and put them together to a .mjpeg file did not work as well.

        "ffmpeg -i input.mp4 image%d.jpeg"
    
    "ffmpeg -f image2 -i image%d.jpeg output.mjpeg", or
    
    "ffmpeg -f image2 -i image%d.jpeg -framerate 25 output.mjpeg"

    "Solutions" like the following one did not work, cause I need a file extension .mjpeg so -c:v mjpeg is not enough cause I end up with sth. like .mov !

    "ffmpeg -i input.mov -c:v mjpeg -q:v 3 -huffman optimal -an output.mov"

    To view my files I use vlc player.

    I always end up with a .mjpeg file which has the length of 10 seconds and only shows the very first image of my 4000 pictures.
