Add VP8 sample encoder application (SVCT supported) vp8enc is a simple VP8 encoder application. It expects yuv420p raw video input and support CQP, CBR and VBR modes. Encoded video is stored in the IVF container fileformat. It supports 2 or 3 temporal layers, which can be activated by using the '--temp_svc X' command line. Note that the alternate reference frame is not used - this design decission was carried on from libyami - in order to allow single Layer 2 frames to be dropped independently. vp8enc and VP8 SVCT are part part of GSOC 2018.

#Libva-utils Project
libva-utils is a collection of utilities and examples to exercise VA-API in accordance with the libva project. --enable-tests (default = no) provides a suite of unit-tests based on Google Test Framework. A driver implementation is necessary to properly operate.
VA-API is an open-source library and API specification, which provides access to graphics hardware acceleration capabilities for video processing. It consists of a main library and driver-specific acceleration backends for each supported hardware vendor.

We also recommend taking a look at the ‘janitorial’ bugs in our list of open issues as these bugs can be solved without an extensive knowledge of libva-utils.
We would love to help you start contributing!
