  • FFMPEG command works on Mac but not on Windows [duplicate]

    24 décembre 2019, par Arthur

    This question is an exact duplicate of :

    Hi I’m working on a project which needs to create animations by playing 2000 charts in 50 fps using FFMPEG, the command is :

    ffmpeg -y -framerate 50 -i img-%04d.png -vb 40M -vcodec h264 esez.mp4

    charts are located in the same folder with name as img-0001.png img-2000.png

    It worked well on my Mac. On Windows, the command can run and generate a mp4 file. But the animation is just black screen on Windows media player. I also tried open with VLC, it has some image, but not proper at all.

  • FFMPEG - Not finding codec parameters

    9 septembre 2024, par Tanner Smith

    I'm trying to convert a sequence of images into a mpeg movie via FFMPEG, although I keep getting an error saying that it could not find the code parameters (Video : mjpeg). A Google search did not bring much up that was useful.

    The images reside in the /tmp directory with names such as img001.jpg and img002.jpg.

    



    Any ideas ?

    



    Thanks

  • avcodec/lcldec : Check mthread_inlen instead of cliping

    27 juillet 2019, par Michael Niedermayer
    avcodec/lcldec : Check mthread_inlen instead of cliping

    Clipping was added in 2009 to avoid crashes.
    
The clipped case would produce a 2nd slice with 0 input
    
thus also producing 0 output.
    
Subsequent checks will cause decoder failure unless both
    
slices have the same output length. thus the only way this
    
would not already fail is if the output from both slices
    
was 0 bytes.
    

    Fixes : Timeout (134sec -> 241ms)
    
Fixes : 15599/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_MSZH_fuzzer-5658127116009472
