Carl Eugen Hoyos	44deb9f68d	mfxdec: Separate mxf_essence_container_uls for audio and video. It is a really bad idea to assign a video codec id when we have set codec_type to audio and vice versa. Prevents detection of mp2 in mxf as mpeg2video. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Tomas Härdin	3cb33fbe91	mxfdec: Compute packet offsets properly. This replaces the old essence_offset code. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Tomas Härdin	f4187945a0	mxfdec: Use MaterialPackage - Track - TrackID instead of the system_item hack. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Tomas Härdin	21cc4b3327	mxfdec: use av_dlog() for 'no corresponding source package found' This is not an error and expected behavior for OPAtom files. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Tomas Härdin	c77a5460b1	mxfdec: Make mxf->partitions sorted by offset. This also zeroes new entries for good measure (used by future patches). Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Tomas Härdin	be78e3f6ec	mxfdec: parse ThisPartition Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Tomas Härdin	775d3b4ab1	mxfdec: Speed up metadata and index parsing. Specifically, this means parsing as before until we run into essence. At that point we seek to the footer and parse until EOF. After that we start seeking backward to the previous partition and parse that until we run into essence or the next partition. This procedure is repeated until we encounter the last partition we parsed in the forward direction. The end result of all this is that large essence containers are not needlessly parsed. This speeds up parsing large files a lot. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Tomas Härdin	0999151962	mxfdec: Make sure DataDefinition is consistent between material track and source track. This fixes 0001GL.MXF.V1.mxf_opatom.mxf and 0001GL00.MXF.A1.mxf_opatom.mxf getting two streams each due to both using the same SourcePackageID. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Tomas Härdin	0ac5e6a8c4	mxfdec: add EssenceContainer UL found in 0001GL00.MXF.A1.mxf_opatom.mxf Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Tomas Härdin	edb5085647	mxfdec: Add hack that adjusts the n_delta calculation when system items are present. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Janne Grunau	682b6db706	mxfdec: Parse IndexTableSegments and convert them into AVIndexEntry arrays. Based on patch from Tomas Härdin <tomas.hardin@codemill.se> and work by Georg Lippitsch <georg.lippitsch@gmx.at> Changed av_calloc to av_mallocz and added overflow checks.	13 years ago
Tomas Härdin	83ab10f6e9	mxfdec: Move FooterPartition to MXFContext and make sure it is never zero. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Joakim Plate	3359246d9a	mxfdec: check return value of avio_seek Avoid modifying state if avio_seek fails. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Philip de Nier	0662eea6b0	mxfdec: skip to end of structural sets This fixes reading of partition packs. The code stops reading after the operational pattern and should skip the array of essence container labels that follow. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Tomas Härdin	d32b3f40c7	mxfdec: parse MXF partitions	13 years ago
Daniel Huang	bcd5d979aa	mov, mxfdec: Employ more meaningful return values. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Tomas Härdin	6547fd9264	mxfdec: consider QuantizationBits between 17 and 24 to be pcm_s24* This fixes playback of BRD38772509.mxf. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	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
Alex Converse	735e601be1	mxfdec: Fix comparison of unsigned expression < 0. 'size' is populated by functions returning int64_t and int that return negative error codes.	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
Alex Converse	0c46e958d1	mxfdec: Fix some buffer overreads caused by the misuse of AVPacket related functions.	13 years ago
Alex Converse	1f6f58d585	mxfdec: Include FF_INPUT_BUFFER_PADDING_SIZE when allocating extradata. This prevents out of bounds reads when extradata is being decoded.	14 years ago
Anton Khirnov	dfc2c4d900	lavf: use designated initialisers for all (de)muxers. It's more readable and less prone to breakage.	14 years ago
Mans Rullgard	0ebcdf5cda	Do not include mathematics.h in avutil.h Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Biurrun	b0a4e5f9e7	Employ correct printf format specifiers, mostly in debug output.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Anton Khirnov	45a8a02a41	lavf: replace avio_seek(SEEK_CUR) with avio_skip where it makes sense Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	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	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	e356fc57a2	lavf: replace all uses of url_fskip with avio_seek 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
Luca Barbato	dfd2a005eb	Replace dprintf with av_dlog dprintf clashes with POSIX.1-2008	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
Axel Holzinger	354b757300	Zero-initialize structs/arrays with {0} instead of {}, which isn't proper C99 Patch by Axel Holzinger, aholzinger at gmx dot de Originally committed as revision 24391 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	39bb30f664	Change all functions referenced in the mxf_metadata_read_table to use the same prototype and also always call them with exactly those arguments. The previous way seems to have worked on all supported platforms, however it was not strictly valid C and would crash e.g. with a compiler that uses stdcall by default. Also avoids warnings if -Wstrict-prototypes is used. Originally committed as revision 23939 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Tomas Härdin	11fdc4d4fc	mxfdec: Improve parsing of the PixelLayout item Originally committed as revision 23898 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
Reimar Döffinger	c7a38887c1	Do D10 AES3 audio conversion in-place instead of using a large on-stack buffer. Originally committed as revision 20567 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	1e69999334	MXF: simply ignore tracks that are invalid due to not having a valid Sequence part instead of failing completely. This partly fixes issue 1470 (broken files created by BBC ingex recorder). Originally committed as revision 20221 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
