Justin Ruggles	be14a37066	aud: fix time stamp calculation for ADPCM IMA WS also allows for removing some unused context fields	13 years ago
Justin Ruggles	10fef6bd6b	aud: simplify header parsing also allows for removing some unused context fields	13 years ago
Justin Ruggles	0e6a8b5cf7	aud: set pts_wrap_bits to 64. Time stamps are not read from the bitstream, so no wrapping is needed.	13 years ago
Justin Ruggles	98c290cc08	cosmetics: indentation	13 years ago
Justin Ruggles	d481227c54	aud: support Westwood SND1 audio in AUD files. Fixes decoding of the handful of "death scream" samples from "Command and Conquer" that use SND1. e.g. http://samples.libav.org/game-formats/westwood-aud/nuyell1.aud http://samples.libav.org/game-formats/westwood-aud/nuyell7.aud	13 years ago
Justin Ruggles	02e7dbf5ad	adpcm_ima_ws: fix stereo decoding Stereo ADPCM IMA WS is planar for VQA version 3 and 2-sample interleaved for VQA version 2.	13 years ago
Justin Ruggles	220506d23f	avcodec: add a new codec_id for CRYO APC IMA ADPCM. The stereo layout and extradata is significantly different from that in Westwood IMA ADPCM, so a separate codec_id is warranted.	13 years ago
Justin Ruggles	4340a6363e	vqa: remove unused context fields, audio_samplerate and audio_bits	13 years ago
Justin Ruggles	7e813d5933	vqa: clean up audio header parsing Fix setting of bit_rate and bits_per_coded_sample. Ask for sample for unsupported VQA versions.	13 years ago
Justin Ruggles	5b4c562897	vqa: set time base to frame rate as coded in the header. According to Multimedia Wiki documentation, the frame rate is not always 15, and the actual value can be found in the header.	13 years ago
Justin Ruggles	9ae846971f	vqa: set packet duration. Also remove unused context field, audio_frame_counter.	13 years ago
Justin Ruggles	53ed79a260	vqa: use 1/sample_rate as the audio stream time base	13 years ago
Justin Ruggles	e1ac69fa27	vqa: set stream start_time to 0. The format has no coded timestamps and must use packet durations to generate them.	13 years ago
Anton Khirnov	1381e9bc92	lavc: postpone the removal of AVCodecContext.request_channels. Although it has been deprecated for a long time, its intended replacement (request_channel_layout) is not actually used anywhere, so request_channels is currently the only way to access that functionality.	13 years ago
Anton Khirnov	dc7ad30fa5	lavf: postpone removing av_close_input_file(). It has been deprecated only recently.	13 years ago
Anton Khirnov	af0292f33a	lavc: postpone removing old audio encoding and decoding API It has been deprecated only recently.	13 years ago
Anton Khirnov	75e2025f57	avplay: remove the -er option. Error recognition flags can and should be set directly with AVOptions.	13 years ago
Anton Khirnov	941e9f2238	lavd: remove deprecated v4l grab device.	13 years ago

Janne Grunau	20ea14d0f8	mxfdec: fix memleak on av_realloc failures	13 years ago
Tomas Härdin	fc85729458	mxfdec: Do not parse slices or DeltaEntryArrays. The most recent demuxing/seeking code does not need them.	13 years ago
Janne Grunau	f028d4d1c3	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 do not 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. Based on several patches by Tomas Härdin <tomas.hardin@codemill.se> and Reimar Döffinger <Reimar.Doeffinger@gmx.de>. Changed av_calloc to av_mallocz, added overflow checks.	13 years ago
Tomas Härdin	1f5f8b2654	mxfdec: Add Avid's essence element key. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
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.
