[FFmpeg-devel] [PATCH v3 2/3] lavc/codec_desc.c: remove AV_CODEC_PROP_TEXT_SUB property

[TADANO Tokumei <aimingoff@pc.nifty.jp>]

To support bitmap type of subtitles, remove AV_CODEC_PROP_TEXT_SUB
property from codec descriptor for AV_CODEC_ID_ARIB_CAPTION.
It is similar way to `libavcodec/libzvbi-teletextdec.c`
(AV_CODEC_ID_DVB_TELETEXT).

Instead, each subtitle decoder has to specify subtitile format.
`libavcodec/libaribb24.c` uses same AV_CODEC_ID_ARIB_CAPTION and
expects AV_CODEC_PROP_TEXT_SUB is defined. Thus add a line to
specify text format subtitle.
