Luca Barbato	0336dea2ef	oggparsetheora: make it more robust	12 years ago
Michael Niedermayer	bb146bb57b	ogg: prevent NULL pointer deference in theora gptopts Additional safety in case a special ogg stream is crafted with the proper number of Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind 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
Anton Khirnov	11d1ca4b2c	Use avcodec_free_frame() to free AVFrames.	12 years ago
Anton Khirnov	9eb296572e	lavf: use a malloced AVFrame in try_decode_frame(). This allows using avcodec_free_frame() to free it properly.	12 years ago
Samuel Pitoiset	cee1950bbb	rtp: Packetization of JPEG (RFC 2435)	12 years ago
Martin Storsjö	71908f0838	smoothstreamingenc: Copy the SAR on the AVStreams as well This is required in chained muxers, if the SAR happens to be set. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	87b017a298	matroskadec: fix a sanity check.	12 years ago
Anton Khirnov	bdb939ad73	matroskadec: only return corrupt packets that actually contain data Fixes bug 372.	12 years ago
Anton Khirnov	1cc569ddda	lavf: zero data/size of the packet passed to read_packet().	12 years ago
Janne Grunau	6746cd7f61	lavf probe: prevent codec probe with no data at all seen This occurs with fuzzed mpeg-ts files. set_codec_from_probe_data() is called with a zeroed AVProbeData since no packet made through for specific stream.	12 years ago
Anton Khirnov	50d1f4437b	mp3dec: read Xing frame TOC index	12 years ago
Anton Khirnov	2d1a1a7f62	mp3dec: use named constants for Xing header flags	12 years ago
Yusuke Nakamura	d17d0ec8c2	mov: support random access point grouping Frames described by this grouping are the starter of a closed or an open GOP. This is useful for open GOP of H.264 stream which is not described by sync sample atom. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Luca Barbato	7d8431004a	matroskadec: properly support BlockDuration	12 years ago
Luca Barbato	c831ebf616	matroskadec: split frame parsing	12 years ago
Luca Barbato	2d0e7713f9	matroskadec: split laces parsing	12 years ago
Luca Barbato	117d8c6d1f	matroska: implement support for ProRes Support Matroska native formatting. On demuxing prepend a Frame container atom (32bit big endian encoded frame size and 'icpf' string). On muxing remove it.	12 years ago
Moritz Bunkus	8071dca3d5	matroska: implement support for ALAC Support Matroska native formatting. On demuxing reconstruct the 36-bytes QuickTime atom that the ALAC decoder expects by prepending the "atom size", "tag" and "tag version" fields missing from the Matroska's CodecPrivate element. On muxing remove the initial 12 bytes Sample files are available: http://www.bunkus.org/videotools/mkvtoolnix/samples/alac/alac-in-matroska.mka and the CoreAudio file it was created from with today's mkvmerge: http://www.bunkus.org/videotools/mkvtoolnix/samples/alac/alac-in-matroska-source.caf Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Luca Barbato	870e75524a	matroskadec: validate lace_size when parsed Stricter validation, explicitly exit on misparsing and some error forwarding from the ebml parsing functions used.	12 years ago
Luca Barbato	c9a39cec70	matroskadec: return meaningful errors in matroska_decode_buffer	12 years ago
Dale Curtis	df1d84121b	matroskadec: fix incorrect unsigned->signed conversion	12 years ago
Luca Barbato	8d4dd55c37	matroskadec: refactor matroska_decode_buffer Make MATROSKA_TRACK_ENCODING_COMP_HEADERSTRIP behave like the other encodings and spare few lines of boilerplate code.	12 years ago
Luca Barbato	581281e242	matroskadec: check realloc in lzo encoding Make all the compression encodings behave the same way.	12 years ago
Luca Barbato	cd4739c4f2	matroska: honor error_recognition on unknown doctypes	12 years ago
Martin Storsjö	84cc314e40	smoothstreaming: Export the mp4 codec tags This fixes stream copy from a format that already has incompatible codec tags set. The chained ismv muxer exports this same codec tag list, so set it on this one as well, to allow the caller (and lavf common code) to set them correctly. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Luca Barbato	9888ffb1ce	mov: check for EOF in long lasting loops A quite widespread pattern in the demuxer is read a 32bit unsigned integer and then loop till this value is reached. Checking for EOF prevents pathological situations.	12 years ago
Benjamin Larsson	6a08955c10	flvenc: silence bogus warning The compiler fails to figure out that enc->codec_type can only have 3 different values. Thus when an if/else is encountered it triggers on the possibility of the else case has not initialized the flags variable. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Clément Bœsch	049ce4facb	id3v2: strdup the genre name explicitly. It would have been done anyway in the av_dict_set() call. This simplifies the code and avoid a warning because of assigning a const string from ff_id3v1_genre_str to a non-const variable. Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Clément Bœsch	ffdd2e9144	lavf/id3v2: do not export empty fields. This also avoids a memleak. Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Michael Niedermayer	a5ea623b36	mov: stsd entries must be at least 16 byte Fix near infinite loop in stsd parsing. Bug found by: Diana Elena Muscalu The size is unsigned according the specification. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Michael Niedermayer	9db67bedf0	mov: detect EOF in mov_read_dref() Avoid a near infinite loop. Issue discovered by cosminamironesei. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Luca Barbato	4ed5ac50d3	file: return proper error on seek failures	12 years ago
Luca Barbato	3f7fd59d15	avformat: fix typo in avformat_close_input The condition should not be &&.	12 years ago
Anton Khirnov	7040c9fac2	mp3enc: write Xing TOC Based on the code by: Peter Belkner <pbelkner@snafu.de>, Michael Niedermayer <michaelni@gmx.at>, Clément Bœsch <clement.boesch@smartjog.com>, Reimar Döffinger <Reimar.Doeffinger@gmx.de>, and Tobias Rapp <t.rapp@noa-audio.com> Alex Converse <alex.converse@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Clément Bœsch	ca8e39dd0d	mp3enc: support MPEG-2 and MPEG-2.5 in Xing header.	12 years ago
Reimar Döffinger	6365e4db79	mp3enc: downgrade some errors in writing Xing frame to warnings Also clarify the meaning of the log message.	12 years ago
Anton Khirnov	3b4bb19e63	lavf: flush the output AVIOContext in av_write_trailer(). This is consistent with stdio and is what we want to do in all cases. Fixes a bug in the voc muxer which didn't flush in write_trailer() previously. This is the cause of the change in the test results.	12 years ago
Anton Khirnov	0c270239c2	lavf: cosmetics, reformat av_write_trailer().	12 years ago
Stefano Sabatini	5d1203f063	avio: flush the internal buffer in avio_close() This is consistent with stdio, and thus what people would naturally expect.	12 years ago
Derek Buitenhuis	1c56cdad33	riff: Add SVQ3 fourcc Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Luca Barbato	44272c1ccc	avformat: refactor avformat_close_input Do not crash if the input format is not allocated yet.	12 years ago
Luca Barbato	4d1f443c3d	avformat: simplify avformat_close_input avio_close checks by itself for NULL condition.	12 years ago
Martin Storsjö	ca6b544ac9	os_support: Choose between direct.h and io.h using a configure check Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	7b07fab567	os_support: Include io.h instead of direct.h on mingw32ce Windows CE doesn't have neither mkdir nor _mkdir officially (only CreateDirectoryW), but mingw32ce has compat wrappers with these names (declared in io.h since direct.h is unavailable). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Christian Schmidt	07584eaf4a	mpegts: check substreams before discarding Allow to extract the AC3 core from TrueHD with the "copy" codec. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Martin Storsjö	62c9ae11a7	Add a smooth streaming segmenter muxer This muxer splits the output from the ismv muxer into individual files, in realtime. The same can also be done by the standalone tool ismindex, but this muxer is needed for doing it in realtime (especially for live streams that need extra handling for updating the lookahead fields in the fragment headers). Using this muxer, one can deliver live smooth streaming from a normal static file web server. (Using ismindex, one can deliver premade smooth streaming files from a static file web server, or prepare files for serving with IIS.) Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	29a9b12b10	file: Add an avoption for disabling truncating existing files on open Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Tomas Härdin	5e3572893d	img2dec: always close AVIOContexts Zero sized files would cause the contexts to leak away. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
