  • What encoders/decoders/muxers/demuxers/parsers/filters do I need to enable in FFMpeg for converting an mp4 video to a gif ?

    21 juin 2020, par kostik

    I am building FFmpeg with custom options to reduce the final size of apk file on android. I want just convert a mp4 file to a gif.
Following is my options specified

    


     --disable-everything
 --enable-decoder=mpeg4,mpegvideo,aac,gif,h264
 --enable-parser=aac,mpeg4video,mpegaudio,mpegvideo,gif,h264
 --enable-demuxer=mpegvideo,aac,mov,gif,h264
 --enable-muxer=mp4,gif,mov,h264
 --enable-protocol=file
 --enable-encoder=mpeg4,mov,gif,h264
 --enable-filter=scale,fps,copy,palettegen,vflip,paletteuse,crop


    


    What other options do i need to add to successfully run this command ?

    


    ffmpeg -y -i input.mp4 -vf "fps=15,scale=320:-1:flags=lanczos" -pix_fmt rgb24 output.gif


    


    or this command

    


    ffmpeg -y -i input.mp4 output.gif


    


    After I added module into Android Studio I run FFmpeg command.
Iam getting this error :

    I also tried to include FULL library and it that case everything worked as expected.

    


    Thanks for your help.

    


  • How to concat videos that have different colour spaces ?

    17 avril 2023, par Ham789

    enter image description hereI writing a Python program that uses subprocess to automate ffmpeg. The program concatenates many videos together with the concat filter. The problem I have is that the colour of some of the videos is very washed out in the final output. I believe this is because the videos have different colour spaces. Some are B.709 and some are B.2020. The B.2020 videos are washed out.

    


    I have tried converting the B.2020 videos to B.709 before concatenating by using the following command on each video but the outputs are still washed out :

    


    ffmpeg -i input.mov -vf colorspace=all=bt709:iall=bt2020:fast=1 output.mov


    


    It wasn't clear to me which way round the arguments should go so I also tried switching the bt2020 and bt709 terms but they still look washed out but with more saturation.

    


    Is this the right approach ? Am I missing some other arguments in order to convert the B.2020 videos to B.709 while preserving their colour ?

    


    I have attached a side by side of the original and converted video.

    


    The metadata of the videos I am trying to concat are :

    


    Video 1

    


      

    • color_range=tv

      • 


    • color_space=bt709

      • 


    • color_transfer=bt709

      • 


    • color_primaries=bt709

      • 


    


    Video 2

    


      

    • color_range=tv

      • 


    • color_space=bt2020nc

      • 


    • color_transfer=arib-std-b67

      • 


    • color_primaries=bt2020

  • How to use FFmpeg and GeForce Hardware to decode and encode 4K MKV movie to 1080p [closed]

    27 janvier 2023, par slyfox1186

    I am struggling with the instruction provided to convert a 4k Movie to 1080p so I can run it easier on my plex server.

    


    I have a Geforce 1080Ti and have enable cuda and all the necessary options when building ffmpeg.

    


    I keep getting a weird error and I am stuck at the below point.

    


    Here is my code that I am working on currently

    


    REM @ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
COLOR 0A
TITLE CONVERT 4K TO 1080P USING GEFORCE HW

PUSHD "%~dp0"

SET "FF=C:\MAB\local64\bin-video\ffmpeg.exe"

    "%FF%" -hide_banner -hwaccel cuda -y -i "%%~dpnG.mkv" -c:v h264_nvenc -preset slow -pix_fmts yuv420p10le -vf scale='1920:-1' -c:a copy "%%~dpnG(1080p).mkv"
    )

ECHO.
PAUSE
EXIT



    


    below is the error output I get when running the above command
