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)	2 years ago

Clément Bœsch	f0f8da545d	lavc/htmlsubtitles: improve handling broken garbage This commit switches off forced correct nesting of tags and only keeps it for font tags. See long explanations in the code for the rationale. This results in various FATE changes which I'll explain here: - various swapping in font attributes, this is mostly noise due to the old reverse stack way of printing them. The new one is more correct as the last attribute takes over the previous ones. - unrecognized tags disappears - invalid tags that were previously displayed aren't anymore (instead, we have a warning). This is better for the end user The main benefit of this commit is to be more tolerant to error, leading to a better handling of badly nested tags or random wrong formatting for the end user.	8 years ago
Clément Bœsch	5c219e289e	avcodec/srtdec: attempt to correct SubRip positioning The positioning was completely wrong. First, the coordinates are expressed in ASS playback resolution (which is by default 384x288). Secondly, the coordinates define a drawing rectangle, not a moving area. The previous code was making subtitles move from a random position to another random position. Here we rescale assuming the video resolution is a DVD one (720x480). We can't really do anything better so far, but since this positioning information is often from a DVD rip we can consider them relatively safe.	10 years ago

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.	11 years ago
Clément Bœsch	0e7782c08e	lavc/ass: honor Default style. The "Default" style written in the header is ignored unless you explicit it in the Dialogue events (it was valid, just ignored). This requires an update of the SubRip test since the ASS output obviously changes.	13 years ago
