DVB Subtitles Support

[Pekka Jääskeläinen <pekka.jaaskelainen@…>]

I think the DVB subtitles patch is ready to be merged. Seems not to crash anymore and timing issues are more or less solved.

• Fixed a crash occuring in 64-bit processors.
• Added an option to make the subtitles disabled by default.

Here's the updated version:

Seems to be lots of duplicate/unnecessary code in here (point/rect classes, bitstream reader). This really should go in avcodec, too.

I can do smaller cleanups like replacing duplicated code, but I don't have time to implement a decoder in ffmpeg because it needs to be in C and might need major changes.

Please just say if this does not have any change getting in without the ffmpeg decoder, in that case I should not bother cleaning it up as it works as is.

Just for information:

Ian Caulfield implemented a ffmpeg DVB sub decoder and I implemented a drawing code that uses it. It should not use any duplicated/unnecessary code.

Ian tries to get the decoder merged in ffmpeg, and I'll give the drawing code some beating, after which I'll try again to get it merged in MythTV. Looks good so far and I'm hopeful it could be merged for 0.19.

The decoder is now merged in ffmpeg. Please update the ffmpeg code and apply the attached patch which adds subtitle display code to MythTV.

Displays subtitles decoded by the new ffmpeg DVB decoder.
