First working version (removed AV1)
cd ~/ffmpeg_sources && wget -O ffmpeg-snapshot.tar.bz2 https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 && tar xjvf ffmpeg-snapshot.tar.bz2 && cd ffmpeg && PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --prefix="$HOME/ffmpeg_build" --pkg-config-flags="--static" --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" --extra-libs="-lpthread -lm" --bindir="$HOME/bin" --enable-gpl --enable-gnutls --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --disable-libaom --enable-nonfree && PATH="$HOME/bin:$PATH" make && make install && hash -r
First Attempt at nvenc
git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git
cd nv-codec-headers
make
sudo make install
- ffmpeg configured with --enable-nvenc (default if the drivers are detected while configuring)
Even after this ffmpeg failed to use because nvidia drivers need to be versos > 440
Had to use buster-backports in source.lst
Failed again with cuda error
Discovered there is no /usr/local/cuda
Following guide from nvidia site
Add-apt-repository is a not a command
Following .run instructiosn
Finally worked
Nvidia-smi worked after I check primary gpu in Proxmox
Ffmpeg worked right after
Full nvdecode and nvenc transcode
ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i input -c:v h264_nvenc -preset slow out.mp4
ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i letsplay.mp4 -c:v hevc_nvenc -preset slow -cq 32 -c:a aac -b:a 128k -tag:v hvc1 -y lets-layout.mp4
Appears 100x faster than libx265 software only encoder speed=5-10x vs speed=0.074x (single core)
Bitrate was around 1Kb/s
