From 7d969fe9e91e39e03041cdfac69bf33337bc2c96 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 7 Mar 2022 12:37:29 +1000 Subject: [PATCH] meson: add a video codec support option This allows to turn on/off all hw implementations for a specific video codec across the tree. Patent encumbered codecs can cause problems for distributions due to the nature of at least MPEG-LA licensing. https://jina-liu.medium.com/settle-your-questions-about-h-264-license-cost-once-and-for-all-hopefully-a058c2149256 is probably the best explaination I can find. From a distro pov, codecs are a jigsaw puzzle, you only seem to become a problem well you fit all the pieces. This patch will allow disabling the mesa piece of the puzzle.
