Video Decode Sample
This sample illustrates the FFMPEG demuxer to get the individual frames which are then decoded on AMD hardware using rocDecode library.
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
./videodecode -i <input video file [required]>
-o <output path to save decoded YUV frames [optional]>
-d <GPU device ID - 0:device 0 / 1:device 1/ ... [optional - default:0]>
-z <force_zero_latency - Decoded frames will be flushed out for display immediately [optional]>
-sei <extract SEI messages [optional]>
-crop <crop rectangle for output (not used when using interopped decoded frame) [optional - default: 0,0,0,0]>
-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]>
