  • How do I fix the "Packet mismatch -92141241 11 214124" error in FFmpeg ?

    25 octobre 2024, par Sacher

    How do I fix the "Packet mismatch -92141241 11 214124" error .
    
I'm going to answer my own question, because the phrase packet size mismatch comes up regularly in posts relating to ffmpeg, but I've nowhere seen a satisfactory solution to it.
    
My command is :

    



    ffmpeg -rw_timeout 1000000 -i rtmp://ip/appName/StreamName -vn -ar 16000 -ac 1 -f segment -segment_format wav -segment_time 3 %d.wav


    



    The error is :

  • FFmpeg Error "No such filter : 'libvmaf' Mac

    4 janvier 2021, par ringola27

    I want to use FFmpeg to calculate PSNR for video sequences.
At first I installed libvmaf with the instruction from here and here. I installed ffmpeg like here. I tried for a test :

    



    ffmpeg -i output4.mpg -i output1.mpg -lavfi libvmaf -f null -


    



    But I get an Error (below). I think I could solve it with ./configure --enable-libvmaf --enable-version3 or ./configure --enable-libvmaf but unfortunately I can not run it (I don't know how).

    



    I hope anyone can help me to solve this problem.
