Video decode performance 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 parallelly.

Prerequisites:

Install rocDecode
FFMPEG
- On Ubuntu
```
sudo apt install ffmpeg libavcodec-dev libavformat-dev libavutil-dev
```
- On RHEL/SLES - install ffmpeg development packages manually or use rocDecode-setup.py script

Build

mkdir video_decode_perf_sample && cd video_decode_perf_sample
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]>
