  • 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"

FOR /R %%G IN (*.mkv) DO (
    "%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

  • cuda invalid resource handle when using h264_cuvid decoder to decode video in my C program

    29 juillet 2021, par ChrisFisher

    I try to use GPU acceleration in my ffmpeg decode program, and I check the codecs of ffmpeg by command :ffmpeg -codecs | grep nv, and it shows that I can use h264_cuvid decoder(In fact, I have already used ffmpeg command line to encode and decode a test video with hardware acceleration and it turned out everything was all fine), but when I use the decoder in my program

    after compiling, I ran the program, and the decoder throw me a error :

    


    ctx->cvdl->cuvidDecodePicture(ctx->cudecoder, picparams) failed -> CUDA_ERROR_INVALID_HANDLE: invalid resource handle
when calling the function avcodec_decode_video2

    


    I don't know why this error occurred, by the way, I use a GTX1060 6G(Sorry I'm not a native English speaker)

    after compiling, I ran the program, and the decoder throw me a error :

    


    ctx->cvdl->cuvidDecodePicture(ctx->cudecoder, picparams) failed -> CUDA_ERROR_INVALID_HANDLE: invalid resource handle
when calling the function avcodec_decode_video2

    


    I don't know why this error occurred, by the way, I use a GTX1060 6G(Sorry I'm not a native English speaker)
