  • How to accelerate minterpolate in ffmpeg ? [closed]

    24 août 2020, par Ken

    I'm using minterpolate of ffmpeg(version git-2020-08-21) with this command on Windows 10 :

    


    ffmpeg -i $file -filter:v "minterpolate=mi_mode=mci:me_mode=bidir:mc_mode=aobmc:vsbmc=1:fps=60" -c:a copy "$file_60fps.mp4"


    


    But the CPU load is only about 15% to 20% while working.

    


    My CPU is AMD 4800H with 8 cores and 16 threads. And I have a NVIDIA GTX1650 with CUDA.

    


    But I cannot find any document about GPU acceleration or multithread methods of minterpolate.

    


    Have tried -threads 16 but nothing changed.

    


    So how to accelerate the process ?

    


  • Not getting required audio codec in ffmpeg

    5 juin 2020, par user13546893

    I am using Colab to run the code.

    



    import os, sys, re

video_file_path = "/content/drive/My Drive/1111/Mrs.Serial Killer 2020 1080p 10bit NF WEBRip Hindi DD+5.1 Atmos x265 HEVC ESub - MoviePirate - Telly.mkv" #@param {type:"string"}
os.environ['fileName'] = filename_raw
os.environ['fileExtension'] = file_extension_raw

!ffmpeg -hide_banner -i "$inputFile" -c copy -strict -2 "$outputPath"/"$fileName".mp4


    



    But the problem is after conversion of mkv video in mp4 format my html5 player can't play the audio. Video is running fine.
Output :

    What changes should I do in the Code ?

    


  • ffmpeg ignores every framerate option, locking the result to 25 fps

    1er août 2023, par Goury

    ffmpeg version 3.4.8-0ubuntu0.2 Copyright (c) 2000-2020 the FFmpeg developers

    


    No matter what I do, ffmpeg just ignores everything and encodes it as if it's 25fps.
    
-framerate 60 does nothing
    
-t 60 does nothing
    
-r 60 makes it to interpolate frames
    
-r:v 60 does the same
    
-vf "fps=60" does the same
    &#xA;-vframes <actual number="number" of="of" frames="frames"></actual> makes it to end the encoding prematurely

    &#xA;

    Everything google shows seems to be outdated, including ffmpegs own documentation
