Last active November 3, 2021 20:19
Created this code while debuggging an issue where Janus only records a video of 8 bytes. Janus log: https://gist.github.com/roxlu/08f32169122dd23e132af7abfb37f928 You can clone this into a vhost; the test html contains a working version that allows you to create multiple video recordings w/o interruptions.

CMake example that shows how you can build Freetype2 with support for Harfbuzz and Harfbuzz with support for Freetype2. This example uses ExternalProject which is the standard way to include external dependencies. Note that we have to patch Freetype2 and Harfbuzz because their CMakelists are not fully CMake compatible (still depend on pkg-config…
# This CMake file will build Freetype and Harfbuzz as external
# projects. We follow the build description as described here:
# https://sourceforge.net/projects/freetype/files/freetype2/2.5.3/ So,
# first we build Freetype2 w/o Harfbuzz, then we build Harfbuzz with
# freetype support after which we rebuild Freetype2 again.
#
# Both CMake files of Freetype2 and Harfbuzz are depending on
# pkg-config to find the dependencies for both projects. I've
# included a patch for Freetype2 and Harfbuzz which allows you to
# build Freetype2 and Harbuzz with pure CMake features. So I removed
