This patch add another ARIB caption decoder using libaribcaption external library. 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. Advantages compared with libaribb24 on ASS subtitle are: * Subtitle positioning. * Multi-rect subtitle: some captions are displayed at different position at a time. * More stability and reproducibility. To compile with this feature: * libaribcaption external library has to be pre-installed. https://github.com/xqq/libaribcaption * configure with `--enable-libaribcaption` option. `--enable-libaribb24` and `--enable-libaribcaption` options are not exclusive. If both enabled, libaribcaption precedes as order listed in `libavcodec/allcodecs.c`.
