jeffqjiangNew 6253248188 Added real decode speed report to set it apart from the current output speed report in sample apps (#409 )

* * rocDecode: Added real decode speed report.
 - The current decode speed report is actually output/display speed report.
 - Due to AV1's extensive use of alternate reference frames that are not display, AV1 decoded frame count and output/displayed frame count can be quite different, making the current speed report not an accurate decode speed measurement.
 - We now added the actual decode speed report, besides the existing speed report, now called output/display FPS.

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:1]>
                  -f <Number of decoded frames - specify the number of pictures to be decoded [optional]>
                  -disp_delay <display delay - specify the number of frames to be delayed for display [optional]>
                  -d <Device ID (>= 0) [optional - default:0]>
                  -z <force_zero_latency - Decoded frames will be flushed out for display immediately [optional]>
