lavc: add support for CODEC_CAP_DELAY in subtitles
This patch adds CODEC_CAP_DELAY support to avcodec_decode_subtitle2. For DVB teletext decoding, a single teletext packet can contain multiple teletext pages. In order to support that, the teletext decoder may buffer some pages. Signed-off-by: Marton Balint <cus@passwd.hu> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
