Ping with rebased patch set. Some chages are added to reflect review results from outside of this ML.
--- 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. 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. Subtitle type 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 japan/osaka_15.ts --- v7: reflect review results from outside of this ML - rename -ass_workaround option to -ass_single_rect and default to false (latest mpv supports multiple ASS rectangle) - add -canvas_size option to specify frame size to render bitmap subtitle - add -caption_encoding option to specify encoding of subtitle text - change behavior of profile C ARIB caption - some cosmetic changes v6: reflect review results from outside of this ML - check clut table overflow - do not adjust vertical position of ruby for ASS format v5: reflect review comments from Mao Hata - reset correct variable in aribcaption_close() - add aribcaption_close() to some places in aribcaption_init() - check if av_strdup() returns NULL in set_ass_header() v4: reflect review results from outside of this ML. - resize bitmap subtitle image to display fonts with correct aspect ratio - multiple font families can be specified by '-font' option - remove 'rendering_backend' option - add document - minor bug fixes v3: combine former 1/4 and 2/4 due to the patchwork shows build error. - fix help option content which incorrectly separated to 2 lines in 2/4. - amend commit message of 4/4.
