Video decode RGB sample
This sample illustrates the FFMPEG demuxer to get the individual frames which are then decoded using rocDecode API and optionally color-converted using custom HIP kernels on AMD hardware. This sample converts decoded YUV output to one of the RGB or BGR formats(24bit, 32bit, 464bit) in a separate thread allowing it to run both VCN hardware and compute engine in parallel.
This sample uses HIP kernels to showcase the color conversion. Whenever a frame is ready after decoding, the ColorSpaceConversionThread is notified and can be used for post-processing.
Prerequisites:
-
Install rocDecode
-
- On
Ubuntu
sudo apt install libavcodec-dev libavformat-dev libavutil-dev- On
RHEL/SLES- install ffmpeg development packages manually or use rocDecode-setup.py script
- On
Build
mkdir video_decode_rgb_sample && cd video_decode_rgb_sample
cmake ../
make -j
Run
./videodecodergb -i <input video file - required>
-o <optional; output path to save decoded YUV frames>
-d <GPU device ID, 0 for the first device, 1 for the second device, etc>
-of <optional: output format bgr, bgra, bgr48, bgr64 etc>
