jeffqjiangNew 8c8904761d Decoder reconfigure fixes. (#157 )

* * rocDecode/HEVC: Fixed a couple of issues with reconfiguration of decoder when video size is changed.
  - Picture width and height variables were interchangeably used to represent coded picture size and display size, resulting reconfiguration errors. Now we use different variables to represent coded and display sizes.
  - Fixed a file overwriting issue in video size change case, where the display size can remain the same when coded size changes with specific cropping offsets.

* * rocDecode/HEVC: Added some fixes to decoder reconfiguration.
  - Added support for MD5 calculation in reconfigure flush callback. This fixed MD5 check failure on conformance streams with size changes.
  - Fixed total decoded frame number report with reconfigure when file dump or MD5 is not enabled. We need to call flush with reconfigure unconditionally (but with different actions).
  - Added the missing reconfigure flush when coded size is not changed but display size is changed.

* * rocDecode/HEVC: Corrected an error in GetDecodedWidth() method. Should use coded_width_, instead of disp_width_.

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]>
