[FFmpeg-devel] Export colormap index and alpha map from dvdsubtitle

[Erik Van Grunderbeeck]

Hallo;

To decode the colormap of subtitles correctly (with info from the ifo files)
the colormap index and alpha values of the subtitle are needed.

I propose exporting them via AVSubtitle and the entries in pict.data[2] and
pict.data[3]. Unless someone has a better proposal.

Attached patch does just that.

Upcoming proposal for dvd decoding (sign. changed from original) will be
available in next few days, subtitle color maps was one of the last things I
needed working on.

Erik
