* * rocDecode/HEVC: Added picture output operation in DPB and display callback function.
  - To avoid serialization of decode submissions and/or display callback in certain cases, increased DPB buffer size by 1 and tweaked picture bumping procedure.

* * rocDecode/HEVC: Added flushing of the remaining pictures from DPB at the end of decode session.

* * rocDecode/HEVC: Changed output_pic_num to num_output_pics to void some confusion. Set top_field_first to 1.

* * rocDecode/HEVC: Added a few return error checks.

Video Decode Sample

This sample illustrates the FFMPEG demuxer to get the individual frames which are then decoded on AMD hardware using VAAPI.

This sample supports both YUV420 8-bit and 10-bit streams.

Prerequisites:

Linux distribution
- Ubuntu - 20.04 / 22.04
ROCm supported hardware
Install ROCm 5.5 or later with --usecase=graphics,rocm --no-32
rocDecode
CMake 3.5 or later
FFMPEG
```
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]>
