Video Decode Sample

This sample illustrates the FFMPEG demuxer to get the individual frames which are then decoded on AMD hardware using VAAPI.

This sample supports both YUV420 8-bit and 10-bit streams.

This sample uses multiple threads to decode the same input video parallely.

Prerequisites:

Linux distribution
- Ubuntu - 20.04 / 22.04
ROCm supported hardware
Install ROCm 5.5 or later with --usecase=graphics,rocm --no-32
rocDecode
CMake 3.5 or later

FFMPEG

sudo apt install ffmpeg libavcodec-dev libavformat-dev libswscale-dev

Build

mkdir build
cd build
cmake ../
make -j

Run

./videodecodeperf -i <input video file [required]> 
                  -t <number of threads [optional - default:4]>
