* lavc/libaribcaption.c: add ARIB caption decoder using libaribcaptionTADANO Tokumei2023-03-281-0/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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`. Signed-off-by: rcombs <rcombs@rcombs.me>

* add libaribb24 ARIB STD-B24 caption decoderJan Ekström2019-02-101-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | * Outputs ASS lines with basic coloring and font scaling for each given region. * Sets the default style to the resolution of the subtitle plane (for example, 960x540 / 36pt font for profile A). * Has options to: * Disable ruby text (which is coded as regions which have half-height text in libaribb24). Enabled by default as without positioning ruby text only confuses as it is usually coded in the beginning of the decoded subtitle line. * Set the working directory, in which libaribb24 will read configuration as well as into which it may save broadcast extra symbols as PNG. Unset by default. The unconventional library check can be explained by the library's current master branch being licensed as LGPLv3, but at the time of writing the latest official release is still licensed under GPLv3. Thus, one either has to wait for the following release, or enable GPLv3.
