* * rocDecode: Added a command option "-md5_check" to compare the MD5 of the decoded YUV to the reference MD5. This ficilitates decoder conformance test automation.
* * rocDecode/HEVC: Changed file and string operation from C code to C++ code.
* * rocDecode/HEVC: Updated README.md for videoDecode sample.

# 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](https://rocm.docs.amd.com/en/latest/release/gpu_os_support.html)
|
|
|
|
* Install [ROCm 5.5 or later](https://rocmdocs.amd.com/en/latest/deploy/linux/installer/install.html) with `--usecase=graphics,rocm --no-32`
|
|
|
|
* rocDecode
|
|
|
|
* CMake `3.5` or later
|
|
|
|
* [FFMPEG](https://ffmpeg.org/about.html)
|
|
```
|
|
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]>
