Hi all, This patch can support hardware-accelerated decode in ffmpeg on Jetson platforms.
ffmpeg application can use accelerated decode to read video files in the following elementary/container formats and dump them in YUV 420 format: H.264, H.265, VP8, VP9. MPEG2, MPEG4 (NOTE: The ffmpeg package does not support MPEG4 container files). Steps to apply the patch: 1) Clone the ffmpeg master branch: git clone git://source.ffmpeg.org/ffmpeg 2) cd ffmpeg 3) Apply the patch 0001-ffmpeg-Accelerated-hardware-decode-support-on-Jetson.patch Command to apply the patch: git apply 0001-ffmpeg-Accelerated-hardware-decode-support-on-Jetson.patch Steps to compile: 1) Install "jetson_multimedia_api" package from latest Jetpack release. Follow link to install jetpack on jetson: https://developer.nvidia.com/embedded/jetpack 2) Install below dependent packages on target using the command (if not already installed by jetpack): sudo apt install libv4l-dev sudo apt install gcc sudo apt install pkg-config sudo apt install libegl1-mesa-dev 3) Run following commands to build and install: ./configure --enable-nvv4l2dec --enable-libv4l2 --enable-shared --extra-libs="-L/usr/lib/aarch64-linux-gnu/tegra -lnvbuf_utils" --extra-cflags="-I /usr/src/jetson_multimedia_api/include/" make sudo make install export LD_LIBRARY_PATH=/usr/local/lib/ 4) Run following commands to decode: H264: ffmpeg -c:v h264_nvv4l2dec -i <input file> <output file> H265: ffmpeg -c:v hevc_nvv4l2dec -i <input file> <output file> MPEG2: ffmpeg -c:v mpeg2_nvv4l2dec -i <input file> <output file> MPEG4: ffmpeg -c:v mpeg4_nvv4l2dec -i <input file> <output file> VP8: ffmpeg -c:v vp8_nvv4l2dec -i <input file> <output file> VP9: ffmpeg -c:v vp9_nvv4l2dec -i <input file> <output file> Example command: ffmpeg -c:v mpeg2_nvv4l2dec -i libmpeg2bug.ts output_420.yuv (Input file is referenced from https://samples.ffmpeg.org/MPEG2/) -Regards, Amit Pandya
