I added the possibility of converting text-based subtitle tracks (such as subrip or ass) to bitmap-based subtitle tracks (such as dvd_subtitle).
I accomplished this by using libass, and basically using the code from vf_subtitles.c to render text subtitles and store the images in the AVSubtitle structure. Of course, this functionality will only work when ffmpeg is configured with --enable-libass. Traian Coza (12): Implemented text to bitmap subtitles! Render only when necessary Retreive width and height from video stream! Initialize ass library only once! Cleaned up Wrote proper headers Close libass after using Added standard headers Rearranged files, all tests are passing! Rearranged files, all tests are passing!
