* dca: fix misaligned access in ff_dca_convert_bitstreamAndreas Cadhalpun2016-01-15
| | | | | | | | | | | | The function is used on unaligned buffers (such as those provided by AVPacket), accessing them as uint16_t causes SIGBUS crashes on architectures like SPARC. This fixes ubsan runtime error: load of misaligned address for type 'const uint16_t', which requires 2 byte alignment Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* put_bits: Remove unused includesVittorio Giovara2014-03-04
| | | | | This requires adding includes to other files that relied on these being included implicitly.
* dca: Move ff_dca_convert_bitstream() to the DCA common codeDiego Biurrun2013-03-27
| | | | This makes the DCA parser and decoder independent.

* dca: Rename dca.c ---> dcadec.cDiego Biurrun2012-08-01
| | | | This will allow adding dca.c with tables used from other files.

* Make channel layout masks unsignedMans Rullgard2011-11-25
| | | | | | | | | | It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dca: ARMv6 optimised decode_blockcode()Mans Rullgard2011-11-25

* dca: set AVCodecContext frame_size for DTS audioJohn Stebbins2011-07-04
| | | | | | | | | | | Set the frame size when decoding DTS audio. This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields. Since frame_size is not currently set, the duration of a frame is being guessed based on the streams bitrate. But for DTS-HD, the bitrate currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly inaccurate frame duration estimate.

* dca: use EXT_AUDIO_ID field to determine core extensionsAnssi Hannula2011-02-24
| | | | | | | | | This avoids the core substream extensions scan when the EXT_AUDIO_ID field indicates no extensions or only unsupported extensions. The scan is done only if the value of EXT_AUDIO_ID is unknown or indicates a present XCh extension which we can decode. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

* dca: consider a stream with XXCh/X96 in ExSS as DTS-HD HRAAnssi Hannula2011-01-21
| | | | | | | | | | | DTS-HD HRA streams do not always have an XBR extension in the extension substream. Instead they can have only XXCh and X96 extensions in there and still be considered DTS-HD HRA. This is also confirmed with Onkyo TX-SR607 receiver which recognizes such a stream as HiRes Audio.
