Ronald S. Bultje	5959bfaca3	floatdsp: move butterflies_float from dsputil to avfloatdsp. This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.	12 years ago
Ronald S. Bultje	42d3246948	floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.	12 years ago
Ronald S. Bultje	d56668bd80	floatdsp: move scalarproduct_float from dsputil to avfloatdsp. This makes the aac decoder and all voice codecs independent of dsputil.	12 years ago

Michael Niedermayer	da4e4d65f4	aacdec: reorder multiuplications to make code safer against too large input values. Fixes CID700697 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	8f4c414df6	Improve wording and spelling of av_log_missing_feature messages.	12 years ago
Diego Biurrun	717addecad	Use proper return values in case of missing features	12 years ago
Diego Biurrun	f75f4194d1	Restructure av_log_missing_feature message Some invocations include a verb in the log message, others do not. Yet av_log_missing_feature expects callers to provide a verb. Change the function to include a verb instead and update the callers accordingly. The result is a more natural function API and correct English in the function invocations.	12 years ago
Michael Niedermayer	bfe735b582	aacdec: detect faac and skip correct amount of startup samples This also fixes aac in adts and other containers than mov. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Akihiro Tsukada	c3c646a868	aacdec: add support for dual mono in Japanese DTV Japanese DTV uses some non standard extensions in AAC audio. One example is 'dual mono', which combines two independent audio into one stereo stream, storing them in left and right channels respectively. Historically, dual mono audio has been used for multi-lingual audio, one for local/native language, and another for english, and usually the "main" (local language) channel should be output without any user interactions. The frames of those dual mono audio are allowed to set ADTS channel_config field to 0, and just contain two SCE's WITHOUT PCE, which is a non standard extension by Japanese DTV standard. (ref. ARIB STD-B32 PartII 5.2.3) This patch adds an AVPacket side data, AV_PKT_DATA_JP_DUALMONO, which indicates that the AVPacket is likely to contain an audio frame with the above dual mono extension, and has the parameter to specify the desired channel selection in that case. It also makes aacdec to detect dual mono and output just the desired channel when this side data is attached.

Hendrik Leppkes	f77fd34bc3	aac: move sample_fmt selection before decoder configuration. The decoder configuration initializes the sbr mdct, which needs to know about the sample format to properly take the scale factor into account. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	faa2930f19	flvdec: reenable extradata passing code This fixes passing junk in stream. It should not have any user vissible effect. We are discarding the new data in the decoder as no case is known where it is needed but it causes problems if used. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
