Hello, I‘ve found one serious vulnerability while auditing this repo. Would you please give me your e-mail so that i can show the detials?

I'm trying to implement Latin character decodification. Would it be possible if I add the Latin tables to convtable.h file static const unsigned int decoder_latin_table[] = { ... } , create a new decoder_handler at decoder.c?

void arib_initialize_decoder(arib_decoder_t *decoder)
{
   arib_finalize_decoder(decoder);
   decoder->buf = NULL;
   decoder->count = 0;
   decoder->ubuf = NULL;
   decoder->ucount = 0;
   decoder->handle_gl = &decoder->handle_g0;
   decoder->handle_gl_single = NULL;
   decoder->handle_gr = &decoder->handle_g2;
   decoder->handle_g0 = decoder_handle_kanji;
   decoder->handle_g1 = decoder_handle_alnum;
   decoder->handle_g2 = decoder_handle_hiragana;
   decoder->handle_g3 = decoder_handle_katakana;
   //New code
   decoder->handle_g4 = decoder_handle_latin;
   decoder->kanji_ku = -1;

What I want is to open closed caption subtitles in pt-BR.

Hello,

we are currently trying to add support to ffmpeg so that arib subtitles would be supported. The subtitles are currently marked as bin_data ([6][0][0][0] / 0x0006) on separate PID (separate pid from video / audio). On the transcoded stream with ffmpeg - it seems that since the ffmpeg is missing support for arib subtitles, it's transcoding the stream somehow wrongly.

Do you have any experience with ffmpeg and would you be willing to help to add support for it? In case of any cost, let us know.

Thank you

初めまして。

現在、wikiを執筆中でしたら大変申し訳ありません。

ffmpegにもARIB subtitlesのサポートを追加するために、aribb24を使いたいと思っているのですが、現在ソースコード以外のドキュメントが無く、ライブラリをどのように使えばいいのかわかりません。
（例えば、arib_buf_region_tのp_startとp_endが何なのか、arib_decode_bufferの入力／出力など）

今後ドキュメント追加の予定はありますでしょうか。

Does anyone have a ts file sample with an arib b24 stream?
I'd like to perform some tests before trying to implement portuguese support, but I can't find a working file.

Hello,

I have been told that installing aribb24 solves an issue that I have with "kaffeine" (KDE program) and vlc it is based on through the German manjaro forum.

I know of compiling with the "classic" ./configure && make but haven't come across this format with Makefile.am and configure.ac - could you add some documentation just like an INSTALL file here or could somebody else point me in the right directions?

As the repository hasn't been updated for some time I was wondering if there are more recent forks available, ideally with some documentation?

Kind regards,
Maik
