This patch set add another ARIB caption decoder using libaribcaption
external library: https://github.com/xqq/libaribcaption
The library decodes subtitles of ISDB-based TV broadcasting.
It is not only for Japanese ARIB STD-B24 caption, but also for
Brazilian ABNT NBR 15606-1 and Philippines version of ISDB-T.
Unlike libaribb24, it supports 3 types of subtitle outputs:
* text: plain text
* ass: ASS formatted text
* bitmap: bitmap image
Default subtitle type is ASS as same as libaribb24, but it can
be changed by `-sub_type` option.
You can see ARIB caption with ffplay tool:
ffplay -sub_type bitmap MPEG.TS
Sample files exist under:
https://streams.videolan.org/streams/ts/ARIB/
Some of them are encrypted and some don't contain ARIB caption data.
Good samples for ARIB caption are:
brazil/07-25_20-33-35_UCV - HD_.ts
japan/channel2[137]_clear.ts
