Vittorio Giovara	87e85a133f	aac: Relax reserved_bit validation Although the specification mandates this bit to zero, it may happen that software tools incorrectly flip it to one, invalidating a possibly valid stream. Relax this restriction, by failing only when AV_EF_BITSTREAM is set. This behaviour is similar to aac decoders in Firefox and Quicktime.

Anton Khirnov	ee964145b5	lavc: remove unused traces of fmtconvert usage Those decoders have been switched to float output and so do not use fmtconvert anymore.	10 years ago

Hendrik Leppkes	3aca10bf76	latm: Always reconfigure if no extradata was set previously AAC LOAS can have new audio config objects in the stream itself. Make sure the decoder reconfigures itself when the first one arrives midstream. Bug-Id: 644 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
John Stebbins	462d5e8e6c	aacdec: set AVFrame sample_rate AVFrame.sample_rate is set in ff_get_buffer, but aacdec calls ff_get_buffer before the samplerate is known. So it needs to be set again before returning the frame.	11 years ago

Anssi Hannula	e10fccf62a	avcodec/aacdec: default to non-wide 7.1 in non-strict mode AAC specification has 7.1(wide) as a default layout for 8-channel streams (channel config 7). However, at least Nero AAC encoder encodes non-wide 7.1 streams using the default channel config 7, mapping the side channels of the original audio stream to the second AAC_CHANNEL_FRONT pair in the AAC stream. Similarly, e.g. FAAD decodes the second AAC_CHANNEL_FRONT pair as side channels, therefore decoding the incorrect streams as if they were correct (and as the encoder intended). FFmpeg currently decodes such files by-the-spec, i.e. after decoding the original front pair will be in AV_CH_FRONT_x_OF_CENTER and the original side pair will be in AV_CH_FRONT_x. As actual intended 7.1(wide) streams are very rare while misencoded 7.1 files actually exist in the wild, default to assuming a 7.1 layout was intended unless in strict mode. Fixes playback of e.g. 8_Channel_ID.m4a in samples. Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
