Tomas Härdin	1888bd1b6d	mxfdec: Make sure mxf->nb_index_tables > 0 in mxf_packet_timestamps() Only the OPAtom demuxing logic is guaranteed to have index tables, meaning OP1a files that lack an index would cause SIGSEGV.	13 years ago
Tomas Härdin	54cbbdd25a	mxfdec: Remove unused variables	13 years ago
Tomas Härdin	6e9081f4d8	mxfdec: Make sure x < index_table->nb_ptses Without this the demuxer will SIGSEGV on files with IndexEntryCount < IndexDuration	13 years ago
Tomas Härdin	085249a379	mxfdec: Ignore the last entry in Avid's index table segments The last entry is the total size of the essence container. Previously a TemporalOffset error would be logged, even though segments like these are expected.	13 years ago
Tomas Härdin	0e764cf541	mxfdec: Don't parse slices or DeltaEntryArrays The most recent demuxing/seeking code doesn't need them	13 years ago
Tomas Härdin	f98726551c	mxfdec: Remove dead/useless code	13 years ago
Tomas Härdin	2eba8da675	mxfdec: Hybrid demuxing/seeking solution This uses the old demuxing code for OP1a and separate demuxing code for OPAtom. Timestamp output is added to the old demuxing code. The seeking code is made to seek to the start of the desired EditUnit only, from which the normal demuxing code takes over (if OP1a). This means we don't use delta entries or slices, only StreamOffsets. OPAtom seeking basically works like before. This also makes D-10 seeking behave the same way as OP1a and OPAtom. In other words, we allow seeking before the start or past the end for D-10 too. This fixes ticket #746.	13 years ago
Tomas Härdin	36c305f9db	mxfdec: Add mxf_edit_unit_absolute_offset() This maps an EditUnit in an index table to the corresponding absolute offset in the file.	13 years ago
Tomas Härdin	b56adc7842	mxfdec: Replace zero IndexDurations with st->duration The mxf_d10 muxer outputs files with zero IndexDurations..	13 years ago
Tomas Härdin	2212e040b7	mxfdec: Add "fake" index to MXFIndexTable to assist seeking This changes mxf_compute_ptses() to be used for MXFIndexTable, and also adds code for computing the fake index to it. This also temporarily disables PTS computation. A future patch will restore it.	13 years ago
Tomas Härdin	8ce41721a4	mxfdec: Add MXFIndexTables This structs collects MXFIndexTableSegments belonging to one IndexSID and some other bits of useful information.	13 years ago
Tomas Härdin	31029e30fa	mxfdec: Move mxf_read_packet*() near the bottom of the file This simplifies future commits.	13 years ago
Tomas Härdin	7d531e83b6	mxfdec: Set DTS and PTS on video packets This involves computing DTS/PTS from the index tables. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Tomas Härdin	8a2cb2abbf	mxfdec: Only sort IndexTableSegments once Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Tomas Härdin	0bcada9f61	mxfdec: Add Avid's essence element key Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Tomas Härdin	1e14bfc117	mxfdec: Add support for Avid indexes These indexes duplicate every entry and have the total size of the essence container as the last entry. This patch also computes the size of the packets when unknown. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Tomas Härdin	89cc8c17df	mxfdec: Check slice_count before freeing slice_offset_entries This fixes SIGSEGV on sliceless (single stream) VBR files Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Tomas Härdin	c0ee522df6	mxfdec: Bring back accumulated_offset that was removed in `5e67e3e` I thought it had to do with file offsets, but's actually the offset inside the essence container. In other words, unbreak multiple EditUnitByteCounts. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Carl Eugen Hoyos	5207f9597e	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. Fixes ticket #721.	13 years ago
Reimar Döffinger	2483f53693	mxfdec: do not try to use an obviously broken index. Also fixes a memleak. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Tomas Härdin	ddcf3e0535	mxfdec: Index table driven demuxing and seeking This adds OPAtom support and proper seeking. D-10 and non-seekable OP1a streams still use the old demuxing/seeking code.	13 years ago
Tomas Härdin	5e67e3eac2	mxfdec: Compute packet offsets properly This replaces the old essence_offset code	13 years ago
Tomas Härdin	5fb800f49a	mxfdec: Use MaterialPackage - Track - TrackID instead of the system_item hack	13 years ago
Tomas Härdin	fd34dbea58	mxfdec: Parse more values in PartitionPack These values include KAGSize, HeaderByteCount and IndexByteCount. The length of the pack itself is also stored, and KAGSize is sanity checked. The FATE sample has KAGSize == 0, which is adjusted to 512. Other bad KAGSizes are set to 1.	13 years ago
Tomas Härdin	7560c26495	mxfdec: Parse TemporalOffsets	13 years ago
Tomas Härdin	623128d782	mxfdec: av_dlog():ify 'no corresponding source package found' This isn't an error. It's also expected behavior for OPAtom files.	13 years ago
Tomas Härdin	336246238e	mxfdec: Compute essence container offsets and lengths into mxf->partitions	13 years ago
Tomas Härdin	289bc14449	mxfdec: Make mxf->partitions sorted by offset This also zeroes new entries for good measure (used by future patches).	13 years ago
Tomas Härdin	e5f9c8927b	mxfdec: Parse ThisPartition	13 years ago
Tomas Härdin	dcd30b83b4	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 aren't needlessly parsed. This speeds up parsing large files a lot.	13 years ago
Tomas Härdin	e1914b5a2f	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.	13 years ago
Tomas Härdin	1170749b39	mxfdec: Add EssenceContainer UL found in 0001GL00.MXF.A1.mxf_opatom.mxf	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
Tomas Härdin	fd1cea6549	mxfdec: Add hack that adjusts the n_delta calculation when system items are present Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Tomas Härdin	7ddb0607f3	mxfdec: Parse IndexTableSegments and convert them into AVIndexEntry arrays Based on work by Georg Lippitsch <georg.lippitsch@gmx.at> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	eef3ea8c71	Rename remaining ByteIOContext to AVIOContext.	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
Tomas Härdin	d377deaaa3	mxfdec: Move FooterPartition to MXFContext and make sure it's never set to zero Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Tomas Härdin	3e48dceac0	mxfdec: Consider QuantizationBits between 17 and 24 to be pcm_s24* This fixes playback of BRD38772509.mxf Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Joakim Plate	a3f4fc813d	[mxfdec] Check return value of avio_seek and avoid modifying state if it fails	13 years ago
Philip de Nier	47886e3644	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	13 years ago
Tomas Härdin	9289eada91	Parse MXF partitions Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 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
