ffmpeg - error processing files generated by premier pro 2022
23 mai 2022, par QRrabbitPlease help with the error, trying to re-encode the source file produced with prores 4444+alpha. Alpha channel is required in my case.


I've tried two separate options, both are erroring out :


$ ffmpeg -i Input.mxf -vcodec prores_ks -profile:v 4 -y Output.mxf 



I'm getting this output

Above I can't even fully see the error since the red text over black background covers the screen :



I have also tried the following encoding options :


-c:v qtrle -pix_fmt argb 



to which, I'm getting the following error :


track 0: could not find essence container ul, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted

Conversion failed!



In case this is helpful, I'm displaying MediaInfo for the source file :

Trouble building ffmpeg with cuda for windows 32 with visual studio 2022
27 juillet 2022, par manouHere is my building process


I open mingw32 from the x64 Native Tools Command Prompt for VS 2022


then in the mingw32 shell :


# cd /
# ./c/Program\ Files/Microsoft\ Visual\ Studio/2022/Community/VC/Auxiliary/Build/vcvars32.bat
# cd ~
# pacman -Sy diffutils git make gcc yasm pkg-config --noconfirm
# git clone --depth 1 https://git.ffmpeg.org/ffmpeg.git ffmpeg 
# git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git nv-codec-headers 
# cd nv-codec-headers/
# make PREFIX=/usr/local
# make install PREFIX=/usr/local
# cd ..
# mkdir nv_sdk
# cp -r /c/Program\ Files/NVIDIA\ GPU\ Computing\ Toolkit/CUDA/v11.7/lib/Win32/* nv_sdk
# cp -r /c/Program\ Files/NVIDIA\ GPU\ Computing\ Toolkit/CUDA/v11.7/include/* nv_sdk

# make -j8
# make install



first I have a bunch of warnings during the making looking like that :

libavutil/opt.c(1075): warning C4133: 'fonction' : types incompatibles - de 'AVPixelFormat *' à 'int *'


And finally the make install returns :

make: *** [ffbuild/library.mak:118: libavutil/avutil-57.dll] Error 1



What am I doing wrong ?
shall I install others packets from pacman ?
