Mans Rullgard	cc276c85d1	Make channel layout masks unsigned 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>	13 years ago

Mans Rullgard	bf00a73ace	dca: clear inactive subbands only once in qmf_32_subbands() Writing zeros to the high entries in the array need only be done once as the cutoff position is constant throughout the loop. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

John Stebbins	49c7006c7e	dca: set AVCodecContext frame_size for DTS audio 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.

Alexandre Colucci	a37f7b6246	Support native DTS channel order when requested.	14 years ago
Reimar Döffinger	636ee66f1c	Fix data_size handling for AC3 and dca decoders. They use now code identical to the AAC decoder. The AC3 decoder previously did not check the data_size and the dca decoder checked against and set wrong values for float.	14 years ago
Vitor Sessak	9d35fa520e	Add AVX FFT implementation. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	14 years ago

Anssi Hannula	853daff682	dca: use EXT_AUDIO_ID field to determine core extensions 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.

Reinhard Tartler	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil 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.
