  • 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.

  • The SSIM values calculated using FFMPEG are not what I expected

    18 mai 2020, par fd-alexer

    I'm trying to encode an m2ts (MPEG-2 Transport Stream) file to mp4 (H.264) and get the ssim value.
    
I did get some SSIM values, but the results were contrary to my expectations.

    



    Are there wrong command options for ffmpeg ?

    



    Encoding and SSIM calculation commands

    



    # encode&#xA;$ ffmpeg -hide_banner -fflags &#x2B;discardcorrupt -i input.m2ts \&#xA;  -c:v libx264 -crf <crf> -preset:v medium \&#xA;  -c:a copy -bsf:a aac_adtstoasc \&#xA;  output_ff_crf-<crf>.mp4&#xA;&#xA;# calculate ssim&#xA;$ ffmpeg -hide_banner -i <a> -i <b> \&#xA;  -lavfi  "[0:v]settb=AVTB,setpts=PTS-STARTPTS[main];[1:v]settb=AVTB,setpts=PTS-STARTPTS[ref];[main][ref]ssim" \&#xA;  -f null -&#xA;</b></a></crf></crf>

    &#xA;&#xA;

    The results of the SSIM

    &#xA;&#xA;

    (a) A=input.m2ts,          B=input.m2ts,           ssim=0.973266&#xA;(b) A=input.m2ts,          B=output_ff_crf-0.mp4,  ssim=0.813347&#xA;(c) A=input.m2ts,          B=output_ff_crf-30.mp4, ssim=0.819897&#xA;(d) A=output_ff_crf-0.mp4, B=output_ff_crf-0.mp4,  ssim=1.000000&#xA;(e) A=output_ff_crf-0.mp4, B=output_ff_crf-30.mp4, ssim=0.972911&#xA;

    &#xA;&#xA;

      &#xA;
    • (d)(e) : These are what I expected.
    • &#xA;

    • (a) : The files are the same, but ssim≠1.
    • &#xA;

    • (b)(c) : SSIMs with CRF=0 and CRF=30 have almost the same value, although the image quality is different.
    • &#xA;

    &#xA;&#xA;

    In the case of HandBrakeCLI

    &#xA;&#xA;

    To determine if there was a problem with input.m2ts, I ran HandBrakeCLI with almost the same parameters as ffmpeg.

    &#xA;&#xA;

    # encode&#xA;HandBrakeCLI --verbose --format av_mp4 --encoder x264 --quality <crf> --x264-preset medium \&#xA;  --aencoder copy \&#xA;  --input input.m2ts --output output_hb_crf-<crf>.mp4&#xA;&#xA;# calculate ssim (same as ffmpeg)&#xA;$ ffmpeg -hide_banner -i <a> -i <b> \&#xA;  -lavfi  "[0:v]settb=AVTB,setpts=PTS-STARTPTS[main];[1:v]settb=AVTB,setpts=PTS-STARTPTS[ref];[main][ref]ssim" \&#xA;  -f null -&#xA;</b></a></crf></crf>

    &#xA;&#xA;

    (b&#x27;) A=input.m2ts,          B=output_hb_crf-0.mp4,  ssim=0.999999&#xA;(c&#x27;) A=input.m2ts,          B=output_hb_crf-30.mp4, ssim=0.972886&#xA;(d&#x27;) A=output_hb_crf-0.mp4, B=output_hb_crf-0.mp4,  ssim=1.000000&#xA;(e&#x27;) A=output_hb_crf-0.mp4, B=output_hb_crf-30.mp4, ssim=0.972886&#xA;

    &#xA;&#xA;

    It's all as I expected. (although A is not ssim=1.0) &#xA;Therefore, I don't see a problem with input.m2ts.

  • FFMPEG Add thumbnail to video [duplicate]

    18 mai 2020, par james-norman

    add a thumbnail to my video file. I have the code that I have compiled with the help of other people from StackOverflow and I have one bit left to finish it off and that is to add a line of code to add video thumbnail.

    you will see some weird text in command like targggget these are words that get replaced by the software so ignore it.

    &#xA;app.path\ffmpeg gets replaced with file-path/ffmpeg
