* * rocDecode/HEVC: Fixed the random crash associated with undecodable RASL pictures.
  - When a CRA picutre occurs, all the pictures in the DPB are emptied. However, the following RASL (Random Access Skipped Leading) picture can still reference these emptied pictures, making them undecodeble.
  - We initialized the reference picture lists with (0xFF), representing invalid picture index. Normally these invalid indices are replaced by valid values during RPS decoding. However, on undecodable RASL pictures, we can not find an existing reference picture in DPB, leaving the invalid index untouched and resulting invalid indexing later on.
  - Now we initialize the reference picture lists with a valid value 0. Also we add index range check on reference buffer at VA-API layer to avoid invalid memory access.

* * rocDecode/HEVC: Fixed a typo in sampel app message.

README.md

Added the command option "-md5_check" to compare the MD5 of the decoded YUV to the reference MD5. This facilitates decoder conformance test automation. (#117 )

Video Decode Sample

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

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]>
              -z <force_zero_latency - Decoded frames will be flushed out for display immediately [optional]>
              -sei <extract SEI messages [optional]>
              -md5 <generate MD5 message digest on the decoded YUV image sequence [optional]>
              -md5_check MD5_File_Path <generate MD5 message digest on the decoded YUV image sequence and compare to the reference MD5 string in a file [optional]>
              -crop <crop rectangle for output (not used when using interopped decoded frame) [optional - default: 0,0,0,0]>
              -m <output_surface_memory_type - decoded surface memory [optional - default: 0][0 : OUT_SURFACE_MEM_DEV_INTERNAL/ 1 : OUT_SURFACE_MEM_DEV_COPIED/ 2 : OUT_SURFACE_MEM_HOST_COPIED]>
