Subject: [FFmpeg-devel] [PATCH 00/12] I added text to bitmap subtitle conversion functionality!
Date: Tue, 3 May 2022 12:13:16 -0400
Message-ID: <20220503161328.842587-1-traian.coza@gmail.com> (raw)
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!
