Oneric	95115fcc18	avcodec/ass: accurately preserve colours ... Colour values used in ASS files without a "YCbCr Matrix" header set to "None" are subject to colour mangling, due to how ASS was historically conceived. A more in-depth description can be found in the documetation inside libass' public ass_types.h header. The important part is, if this header is not set to "None", the final output colours can deviate from the literal value specified in the file. When converting from non-ASS formats we do not want any colour shift to happen, so let's set the appropiate header. NB: ffmpeg's subtitle filter, does not follow libass' documentation regarding colour mangling, thus hiding the bug. Anything based on VSFilter, XySubFilter or e.g. mpv do and might show the issue. (Of course native ASS subs, which _do_ rely on colour mangling won't work properly with the subtitle filter, but this can be fixed another time)	2022-12-03 19:08:39 +01:00

Clément Bœsch	5039aadf68	avcodec/ass: explicit PlayRes[XY] ... This avoids the following libass warning when using the subtitles filter: "Neither PlayResX nor PlayResY defined. Assuming 384x288" Subtitles tests change because the output is ASS and the PlayRes[XY] ends up in the output.	2014-06-18 18:22:40 +02:00
