# Video Decode 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 parallely.
|
|
|
|
## 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
|
|
```
|
|
./videodecodeperf -i <input video file [required]>
|
|
-t <number of threads [optional - default:4]>
|
|
-d <Device ID (>= 0) [optional - default:0]>
|
|
-z <force_zero_latency - Decoded frames will be flushed out for display immediately [optional]>
|
|
-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]>
|
