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
FFMPEG
- 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

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>
