# 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.
|
||||
|
||||
## Build and run the sample:
|
||||
```
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
make -j
|
||||
./videodecode -i <input video file - required> -o <optional; output path to save decoded YUV frames> -d <GPU device ID, 0 for the first device, 1 for the second device, etc>
|
||||
```
