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
Nicolas George	9cec1bbd14	ogg: propagate return values and return more meaningful error values Signed-off-by: Diego Biurrun <diego@biurrun.de>	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
Diego Biurrun	b751f61106	Remove stray extra arguments from av_dlog() invocations.	14 years ago
Mans Rullgard	e65ab9d94f	Remove unused variables	14 years ago
Clément Bœsch	e575685fad	Cosmetics: fix prototypes in oggdec Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Clément Bœsch	5780f41af5	oggdec: fix memleak with continuous streams. This avoids the creation of a new AVStream instead of replacing it when a stream reset occurs (track change with some webradios for example). Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Clément Bœsch	b3bbc6fdc5	oggdec: use explicit AVInputFormat struct initializers Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Clément Bœsch	f95257d27c	oggdec: simplify ogg_probe Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Diego Biurrun	045dd4b928	Replace some commented-out debug printf() / av_log() messages with av_dlog().	14 years ago
Clément Bœsch	dc713546d4	oggdec: reindent after `8f3eebd6` Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Michael Niedermayer	52512d0a43	oggdec: use av_freep() instead of av_free() Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Clément Bœsch	8f3eebd663	oggdec: simplify audio chained ogg streams support Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	14 years ago
Clément Bœsch	47dec30edb	oggdec: fix demuxing chained audio streams Chained ogg served by icecast and mpd should demux properly now. Fixes issue2337 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	14 years ago
Anton Khirnov	8978fedaee	avio: introduce an AVIOContext.seekable field Use it instead of url_is_streamed and AVIOContext.is_streamed.	14 years ago
Anton Khirnov	66e5b1df36	avio: deprecate url_feof AVIOContext.eof_reached should be used directly instead. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Anton Khirnov	76aa876e69	avio: avio_ prefix for url_fsize Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Anton Khirnov	e51975392d	avio: deprecate url_fgetc and remove all it uses Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Anton Khirnov	a2704c9712	avio: add avio_tell macro as a replacement for url_ftell Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Anton Khirnov	6b4aa5dac8	avio: avio_ prefix for url_fseek Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Anton Khirnov	b7effd4e83	avio: avio_ prefixes for get_* functions In the name of consistency: get_byte -> avio_r8 get_<type> -> avio_r<type> get_buffer -> avio_read get_partial_buffer will be made private later get_strz is left out becase I want to change it later to return something useful. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Anton Khirnov	ae628ec1fd	avio: rename ByteIOContext to AVIOContext. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Reimar Döffinger	6bd69e6ada	oggdec: Fix incorrect assumption about header/data interleaving 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. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	c6610a216e	Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice. This also lists the objects from those two libraries as internal (by adding the ff_ prefix) so that they can then be hidden via linker scripts.	14 years ago
Aaron Colwell	365d8e471d	Ensure that data_offset is set correctly when there are partial data packets before the first complete one. Patch by Aaron Colwell [acolwell chromium org]. Originally committed as revision 25846 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Anton Khirnov	03700d399b	Export metadata in the generic format. Deprecate old conversion API. patch by Anton Khirnov anton _at_ khirnov _dot_ net Originally committed as revision 25493 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Eli Friedman	461628c6a8	Fix printf format warnings patch by Eli Friedman <eli dot friedman at gmail dot com> Originally committed as revision 23547 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	f1a0518524	Enable AVFMT_GENERIC_INDEX for Ogg demuxer. This avoids the many seeks needed for binary search when seeking to a previously seen location. Originally committed as revision 23279 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	adc725b558	oggdec: Move warning about missing granule to the correct place Originally committed as revision 22891 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
James Darnley	66061a1220	Add VorbisComment writing to FLAC files. Patch by James Darnley <james darnley at gmail>. Originally committed as revision 22605 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	81b743eb10	oggdec: Pass packets to header() until the stream is done with them This fixes some old ogm files that had the 3rd vorbis header after a data packet in another stream. This is invalid in ogg, but this change shouldn't affect the behaviour of any valid file. Originally committed as revision 22478 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	d8b91fae1d	oggdec: Seek to keyframes Originally committed as revision 22463 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	873d117e4b	oggdec: Determine pts and filepos on a packet basis in read_timestamp This takes into account whether the granule defines the start or end times of packets, and sets the correct file offset of the associated page. Originally committed as revision 22462 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	6abaa27211	oggdec: Move PTS/DTS calculation to a function Originally committed as revision 22461 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

David Conrad	dfaed51f04	oggdec: Move ogg_find_stream and ogg_gptopts to oggdec.h (skeleton will need them) Originally committed as revision 22455 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	50a9d32310	oggdec: Set data_offset to the right value Otherwise it gets set automatically to a page midstream and prevents seeking to the first page. Originally committed as revision 22454 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	73823cb941	oggdec: Save offset of the page needed to reconstruct the current packet Originally committed as revision 22453 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	be4a113264	Make sure the header value used to avoid repeating headers on seeking to the start and to avoid initializing codecs with missing headers is set for all streams. Fixes issue 1723. Originally committed as revision 21693 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	ecc0027bc6	Fix playback with invalid files that don't set the continuation flag for pages that continue packets started in prior pages. Fixes issue1248 Originally committed as revision 21688 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	2d4970d88d	oggdec: Set dts when known Originally committed as revision 21134 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Justin Ruggles	15299b3821	Calculate correct packet durations when demuxing Ogg/Speex. This involves determining if there is any delay in the first packet and/or any truncation in the final packet. Originally committed as revision 20216 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
