# onevpl examples
> Video processing examples using onevpl library.
## Requirements
onevpl api and one of the implementation.
https://github.com/oneapi-src/oneVPL
### Install onevpl api from source
```
$ git clone https://github.com/oneapi-src/oneVPL onevpl
$ cd onevpl
$ mkdir build && cd build
$ cmake ..
$ make
$ sudo make install
```
### Install onevpl cpu implementation from source.
```
$ git clone https://github.com/oneapi-src/oneVPL-cpu onevpl-cpu
$ cd onevpl-cpu
$ source script/bootstrap
$ script/build
$ sudo script/install
```
## Build examples
```
$ mkdir build && cd build
$ cmake ..
$ make
```
## Run examples
```
$ python hello_encode.py
$ ./build/encodeapp -i cars_320x240.i420 -w 640 -h 480 -c hevc
```
## HD video encoding
Run hevc encoder 720p file using onevpl-cpu.
```
$ wget https://media.xiph.org/video/derf/y4m/KristenAndSara_1280x720_60.y4m
$ ffmpeg -i KristenAndSara_1280x720_60.y4m -f rawvideo -pix_fmt yuv420p KristenAndSara_1280x720_60.yuv
$ ./hello_encode -i KristenAndSara_1280x720_60.yuv -h 1280 -w 720 -c hevc -r 60
