* avcodec: move end zeroing code from av_packet_split_side_data() to ↵Michael Niedermayer2014-01-071-0/+10
| | | | | | | | | | | | | | | avcodec_decode_subtitle2() This code changes the input packet, which is read only and can in rare circumstances lead to decoder errors. (i run into one of these in the audio decoder, which corrupted the packet during av_find_stream_info() so that actual decoding that single packet failed later) Until a better fix is implemented, this commit limits the problem. A better fix might be to make the subtitle decoders not depend on data[size] = 0 or to copy their input when this is not the case.

* lavc: add support for CODEC_CAP_DELAY in subtitlesMarton Balint2013-10-271-2/+2
| | | | | | | | | | | 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>
