[FFmpeg-devel] [PATCH 2/2] tests/matroska: Add test for WebVTT in WebM

Andreas Rheinhardt andreas.rheinhardt at outlook.com
Mon Mar 29 16:18:57 EEST 2021


Specifically test that the WebVTT flavour is correctly mapped to
the Matroska/WebM CodecID and back; and test that dispositions
unsupported by WebM are discarded even when they would be supported
by Matroska.
