[vlc-devel] [PATCH v3 00/22] Add support for OpenGL filters

[Romain Vimont]

Previous versions:
v1: https://mailman.videolan.org/pipermail/vlc-devel/2020-June/134800.html
v2: https://mailman.videolan.org/pipermail/vlc-devel/2020-July/134960.html

Changes since v2:
 - update documentation after changes from v1 to v2 (patch 21)
 - move mock.c to filter_mock.c (for consistency with filter_draw.c) (patch 22)
 - add "msaa" parameter to mock filter (for testing multisampling) (patch 22)

The --gl-filter CLI option is kept to be able to run and test filters as
introduced by this patchset. We plan to remove it once the OpenGL filter_t
implementation is merged (after that, we will be able execute OpenGL filters
using the --video-filter option).

The MR has been updated: https://code.videolan.org/rom1v/vlc/-/merge_requests/12
