  • 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

    )

ECHO.
PAUSE
EXIT

  • FFMPEG cannot encode .MP4 to usable .Y4M RAW video : "Operation not permitted"

    26 janvier 2020, par Ham789

    I am running ffmpeg version 4.2.2 on macOS Sierra and I cannot decode a RAW video.

    First I create the .Y4M video :

    ffmpeg -y -i inputfolder/GH012088.MP4 temp_raw_video.Y4M

    Then I try to input it to ffmpeg :

    ffmpeg -i temp_raw_video.Y4M

    However I get the following error in the terminal : temp_raw_video.Y4M: Operation not permitted

    I have checked the permissions for the ’temp_raw_video.Y4M’ file and I have both read and write permissions.

    I have tried the above with .MOV videos from an iPhone and it works fine.

    The problem seems to be with the .MP4 videos I am trying to convert. These videos were taken with a GoPro camera.

    What is going on here ? Please see the GH012088.MP4 file info below :
