Video Decode Sample
This sample illustrates the FFMPEG demuxer to get the individual frames which are then decoded on AMD hardware using rocDecode library.
This sample uses multiple threads to decode the same input video parallely.
Prerequisites:
-
Linux distribution
- Ubuntu -
20.04/22.04
- Ubuntu -
-
Install ROCm 5.5 or later with
--usecase=graphics,rocm --no-32 -
rocDecode
-
CMake
3.5or later -
sudo apt install ffmpeg
Build
mkdir build
cd build
cmake ../
make -j
Run
./videodecodeperf -i <input video file [required]>
-t <number of threads [optional - default:4]>
-d <Device ID (>= 0) [optional - default:0]>
-z <force_zero_latency - Decoded frames will be flushed out for display immediately [optional]>
-m <output_surface_memory_type - decoded surface memory [optional - default: 0][0 : OUT_SURFACE_MEM_DEV_INTERNAL/ 1 : OUT_SURFACE_MEM_DEV_COPIED/ 2 : OUT_SURFACE_MEM_HOST_COPIED]>
