extra-ldflags="-L$HOME/ffmpeg_build/lib" \īut I get the error ERROR: amf requested but not foundĪnd the instructions for how to include AMF are vague. extra-cflags="-I$HOME/ffmpeg_build/include" \ ffmpeg -f concat -i join.txt -c copy concatenate.mov. The following command appends file2.mov to the end of file1.mov and saves the resulting file as concatenate.mov. Then I tried to compile ffmpeg from the source with: PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig". Specify the join.txt file as the input file. I will get this error: Unknown encoder 'h264_amf'Īlso, the different are installed from here: When I install normall ffmpeg or use the ffmpeg from ppa:savoury1/ffmpeg4, these not have the amf codec enabled (even though 4.3 is suppose to the code enable by default). I am trying to get my ffmpeg to use the GPU when doing conversion as such: ffmpeg -i input.avi -c:v h264_amf output.mp4 I'm on the AWS g4ad server instance that has AMD Radeon Pro V520 GPU.
