Michael Niedermayer	8443082db6	ogg: rewrite first timestamp reading code. this is simpler and closer to how timestamps are found for seeking. Fixes Ticket1186 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	c7c976c6d7	oggdec: Safety check against stream counts being inconsistent in seek() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	9bb3b7d028	oggdec: Recreate streams only in the 1 stream case. Other cases are not supported and lead to inconsistencies which can lead to out of array writes. Reported-by: Dale Curtis <dalecurtis@chromium.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Dale Curtis	ef0d779706	Fix uninitialized reads on malformed ogg files. 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. Signed-off-by: Dale Curtis <dalecurtis@chromium.org> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Reimar Döffinger	030e96fe55	oggdec: improve warning message. Print whether it was a keyframe or a non-keyframe that was incorrectly marked as the other. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	787528b4a6	Detect theora keyframes by content in Ogg demuxer. A lot of files do not mark keyframes correctly via granule, so detect keyframe or not based on data and complain if it mismatches. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	8162c6f0bd	oggdec: add missing ogg_reset on seek. It would never be called when the searched-for position was already in the index. In the other cases, the ogg_reset at the end of the read_timestamp function handled it. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	1b0dc96fc9	oggdec: fix keyframe seeking when granule_is_start is 0. In this case, the pts values will be delayed by one, but at the same time pts values might only be supplied for e.g. keyframes. This results on only the frame after the keyframe having a pts value. As a hack, make read_timestamp return the keyframe position together with the pts from a following frame when seeking to a keyframe. Fixes trac issue #438. However it causes the read_timestamp function to return a pos value that is actually before the packet with the indicated pts. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Reimar Döffinger	d7b542ae29	Fix potential infinite discard loop. Fixes trac issue #438. Seeking in that sample would cause ogg_read_timestamp to fail because ogg_packet would go into a state where all packets of stream 1 would be discarded until the end of the stream. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago

Diego Biurrun	e873c03ac7	misc Doxygen markup improvements	13 years ago
Anton Khirnov	c3f9ebf743	lavf: make av_set_pts_info private. It's supposed to be called only from (de)muxers.	13 years ago
Anton Khirnov	a2faa95151	lavf: make some seeking functions private Specifically av_update_cur_dts(), av_seek_frame_binary() and av_gen_search(). They are not supposed to be called outside lavf.	13 years ago
Anton Khirnov	84ad31ff18	lavf: replace av_new_stream->avformat_new_stream part II. 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.	13 years ago

Laurent Aimar	0e7efb9d23	oggdec: fix out of bound write in the ogg demuxer Between ogg_save() and ogg_restore() calls, the number of streams could have been reduced. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago

Michael Niedermayer	7e7012d0b4	oggdec: subtract time of first packet only from duration when it is significant this fixes accuracy with normal ogg files while keeping support for ogg files starting at times different from 0 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago

Chris Evans	4cc3467e7a	oggdec: prevent heap corruption. 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>	14 years ago

Reimar Döffinger	0a94020b5b	oggdec: Abort Ogg header parsing when encountering a data packet. Fixes Bugzilla #11. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Ronald S. Bultje	9ed6cbc3ee	ogg: fix double free when finding length of small chained oggs. 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.	14 years ago
