Anton Khirnov	8ad3267ce3	oggdec: do not fall back on binary search in the generic code. Binary search is already attempted in the format-specific seek function, so the fallback is only reached if binary search failed already.	12 years ago
Luca Barbato	f963f701d9	ogg: relax demuxer conformance checks Some samples in the wild are missing headers that are expected by the specification but in practice do not affect decoding.	12 years ago
Michael Niedermayer	e278500181	oggdec: Support byte based seeking Fixed Ticket2317 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	7cb27d216d	oggdec: Support chained streams, support replacing streams in multistream files. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Conflicts: Changelog	12 years ago
Michael Niedermayer	c994bb2fb7	oggdec: Leave treatment of serial changes to the decoder. Attempting to re-parse the headers at demuxer level is a pandora box the way its done currently. This allows full reconfiguration of vorbis streams Fixes Ticket2117 Fixes Ticket2121 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	c5cf58d4b9	oggdec: resync from the last page. Previously we re synced from where we where which cam lead to loosing pages. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Luca Barbato	d894f74762	oggdec: make sure the private parse data is cleaned up	12 years ago
Luca Barbato	89b51b570d	oggdec: free the ogg streams on read_header failure Plug an annoying memory leak on broken files.	12 years ago

Luca Barbato	ba064ebe48	oggdec: check memory allocation	12 years ago
Luca Barbato	f5f1cf5224	oggdec: K&R cosmetic formatting	12 years ago
Michael Niedermayer	9db3fb6ed8	oggdec: prevent codec from changing through ogg_replace_stream() This prevents inconsistencies leading to out of array accesses. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	4c273eb64c	oggdec: print a warning if the number of headers mismatch expectations. This is based on: commit `7751e4693d` Author: Luca Barbato <lu_zero@gentoo.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	cc4deafed1	oggdec: print error when headers couldnt be parses successfully Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Luca Barbato	d1f05dd183	ogg: calculate the start position once all the headers are parsed The fisbone packets can be muxed in any order as long the last one comes before the first data packet.	12 years ago
Luca Barbato	7751e4693d	ogg: check that the expected number of headers had been parsed Not having the header for a codec is a tell-tale of a broken file.	12 years ago
Clément Bœsch	ea5bd7ea6f	lavf/oggdec: check for begin-of-stream flag in case of chained streams. Fix Ticket #1617, revealing a regression I introduced in `8f3eebd`. We need to make sure no stream is added in between Ogg context save and restore operations (because it would likely lead to a mismatch between ogg->nstreams and AVFormatContext->nb_streams after the restore op). This is the reason the ogg->state check is added in ogg_new_stream(). Before this patch, checking for ogg->headers was preventing this: ogg->headers is always set before any ogg save/restore (though, it was also preventing from creating the stream when necessary).	12 years ago
Clément Bœsch	094991eb69	lavf/oggdec: reword stream creation error message.	12 years ago
Clément Bœsch	23f6420026	lavf/oggdec: reindent and comment blocks.	12 years ago
Clément Bœsch	a218c5ebd2	lavf/oggdec: make stream replacement less convoluted. Also re-use the allocated buffer instead of re-allocating a new one.	12 years ago
Clément Bœsch	e18ea76523	lavf/oggdec: more explicit zeroing of the new ogg stream.	12 years ago
Clément Bœsch	3a89553347	lavf/oggdec: rework allocations in ogg_new_streams().	12 years ago
Clément Bœsch	edca80387c	lavf/oggdec: simplify destroying streams with chained audio streams. nstreams is assumed to be 1 at that point, so the loop is pointless.	12 years ago
Clément Bœsch	277ddf127d	lavf/oggdec: rename str to sid. "str" is misleading here (it's often used for string). "sid" makes more sense to identify a stream id.	12 years ago
Clément Bœsch	e1ca1dd71b	lavf/oggdec: remove a comment not matching anything.	12 years ago
Clément Bœsch	bf8bfc6a11	lavf/oggdec: inline ogg_get_headers(). There is no point in a distant definition of a small function like this used only once. Additional spacing to distinguish better the block.	12 years ago
Reimar Döffinger	69aeba1396	oggdec: Initialize stream index to -1 in ogg_packet. The previous method of having to initialize it outside lead to incorrect code: even if it was initialized, it usually was only initialized once, thus a packet that could not be matched to any stream would just be processed with the return values from the previous call. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Reimar Döffinger	a4163b2d65	oggdec: simplify start time calculation code. Also slightly more correct behaviour in case streams_left for some reason is 0 from the start. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Michael Niedermayer	9e1c55cfde	oggdec: check stream index before using it in ogg_get_length() Fixes crash based on a uninitialized array index read. If the read does not crash then out of array writes based on the same index might have been triggered afterwards. Found-by: inferno@chromium.org Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nicolas George	e62fd6619f	oggdec: add support for Opus codec. This patch also introduces CODEC_ID_OPUS.	13 years ago
Michael Niedermayer	e0eaf10049	oggdec: fix regression that caused reading the whole file during open Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
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	5f9f78dc9b	oggdec: pass avformat context to ogg_reset() 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
