* Fix uninitialized reads on malformed ogg files.Dale Curtis2012-03-08
| | | | | | | | | | The ogg decoder wasn't padding the input buffer with the appropriate FF_INPUT_BUFFER_PADDING_SIZE bytes. Which led to uninitialized reads in various pieces of parsing code when they thought they had more data than they actually did.

* lavf: make av_set_pts_info private.Anton Khirnov2011-11-30
| | | | It's supposed to be called only from (de)muxers.
* lavf: make some seeking functions privateAnton Khirnov2011-10-28
| | | | | | | Specifically av_update_cur_dts(), av_seek_frame_binary() and av_gen_search(). They are not supposed to be called outside lavf.
* lavf: replace av_new_stream->avformat_new_stream part II.Anton Khirnov2011-10-19
| | | | | | | | Manual replacements are done in this commit. In many cases, the id is some constant made up number (e.g. 0 for video and 1 for audio), which is then not used in the demuxer for anything. Those ids are removed.

| | | | | | | Between ogg_save() and ogg_restore() calls, the number of streams could have been reduced. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* oggdec: prevent heap corruption.Chris Evans2011-07-11
| | | | | | | | Specifically crafted samples can reinit ogg->streams[] while reading samples, and thus we should not cache old pointers since these may no longer be valid. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* ogg: fix double free when finding length of small chained oggs.Ronald S. Bultje2011-06-29
| | | | | | | | ogg_save() copies streams[], but doesn't keep track of free()'ed struct members. Thus, if in between a call to ogg_save() and ogg_restore(), streams[].private was free()'ed, this would result in a double free -> crash, which happened when e.g. playing small chained ogg fragments.

* oggdec: Fix incorrect assumption about header/data interleavingReimar Döffinger2011-02-08
| | | | | | | | | | | | Currently (since the data_offset fix) the ogg demuxer assumes that after the first non-header packets in any stream no more header packets will follow. This is not guaranteed, so change the code back again to wait until it has finished the headers for all streams before returning from ogg_get_headers. This fixes issue 2428.
