Install dependencies:\n\n- From the official repositories, meson and GStreamer:\n\n $ sudo apt install meson libgstreamer-plugins-base1.0-dev\n\n- In order to install Kvazaar, follow the instructions on\nhttps://github.com/ultravideo/kvazaar. (Make sure the resulting shared object\nis under you LD_LIBRARY_PATH at runtime.)\n\n2. To build gst-kvazaar plugin with meson, move to your local project directory and run\nthe following:\n\n $ meson build\n $ ninja -C build\n\nTesting Pipelines\n-----------------\n\n $ GST_PLUGIN_PATH=build/src gst-inspect-1.0 kvazaarenc\n $ GST_PLUGIN_PATH=build/src gst-launch-1.0 videotestsrc ! kvazaarenc ! avdec_h265 ! videoconvert ! fpsdisplaysink\n\nSelective encryption features\n-----------------------------\n\ngst-kvazaar implements Kvazaar selective encryption features. Here is an example\npipeline of how to do it:\n\n $ 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\n\nThe encrypted byte stream can be decrypted with OpenHEVC. An implementation of\nthe OpenHEVC decoder is available in gst-openhevc. Here is an example pipeline\nshowing how to use openhevcdec together with kvazaarenc:\n\n $ 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\n\nNote\n----\n\nSome part of the source code is in commentary because there are features still\nnot implemented.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fahresse%2Fgst-kvazaar","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fahresse%2Fgst-kvazaar","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fahresse%2Fgst-kvazaar/lists"}
