A decoder wrapper for the libaribb24 library found in various distributions and currently utilized by VLC.
Requires GPLv3 with the current most recent release, but as the current library master is LGPLv3, any newer releases will require only LGPLv3. If the library is not found in your distribution, it is available at: https://github.com/nkoriyama/aribb24 A test sample can be found at: https://kuroko.fushizen.eu/samples/arib_captions_colors_positioning_ruby_subpics.ts An example of how the decoded output currently looks can be found at: https://megumin.fushizen.eu/screenshots/arib_subs/mpv-shot0004.png I will proceed to making a FATE test as soon as I figure out the simplest way to limit an MPEG-TS stream to some PIDs without doing full remuxing. (I think dvblast has something like this so I might take a look at that) The decoded subtitles might or might not have durations set, so with ffmpeg.c `-fix_sub_duration` is required. Regarding positioning: I have an initial version of positioning implemented, but unfortunately it requires multiple subtitle lines per AVSubtitle, and many applications seem to fail at handling them, including the encoding portions of libavformat/libavcodec (all lines end up concatenated into a single line, even though that is 100% invalid as there is a header included). Thus I have decided to post the first version out now, as when the ruby blocks are not included as a distraction, single-line output seems to be fine and readable/enjoyable.
