Kvazaar encoder plugin

What it is

This is a video encoding element for GStreamer 1.0 based on Kvazaar, a LGPL HEVC encoder.

Building with meson

This installation guide has been tested under Debian 9.8.

  1. Install dependencies:
  • From the official repositories, meson and GStreamer:

$ sudo apt install meson libgstreamer-plugins-base1.0-dev

  • In order to install Kvazaar, follow the instructions on https://github.com/ultravideo/kvazaar. (Make sure the resulting shared object is under you LD_LIBRARY_PATH at runtime.)
  1. To build gst-kvazaar plugin with meson, move to your local project directory and run the following:

$ meson build $ ninja -C build

Testing Pipelines

$ GST_PLUGIN_PATH=build/src gst-inspect-1.0 kvazaarenc $ GST_PLUGIN_PATH=build/src gst-launch-1.0 videotestsrc ! kvazaarenc ! avdec_h265 ! videoconvert ! fpsdisplaysink

Selective encryption features

gst-kvazaar implements Kvazaar selective encryption features. Here is an example pipeline of how to do it:

$ GST_PLUGIN_PATH=build/src gst-launch-1.0 videotestsrc ! kvazaarenc crypto=on key=14,41,81,1,51,98,105,1,17,54,230,0,89,165,255,123 preset=ultrafast ! avdec_h265 ! autovideosink

The encrypted byte stream can be decrypted with OpenHEVC. An implementation of the OpenHEVC decoder is available in gst-openhevc. Here is an example pipeline showing how to use openhevcdec together with kvazaarenc:

$ gst-launch-1.0 videotestsrc ! kvazaarenc crypto=on key=14,41,81,1,51,98,105,1,17,54,230,0,89,165,255,123 preset=ultrafast ! openhevcdec crypto=on key=14,41,81,1,51,98,105,1,17,54,230,0,89,165,255,123 ! xvimagesink

Note

Some part of the source code is in commentary because there are features still not implemented.
