Anton Khirnov	2df0c32ea1	lavc: use a separate field for exporting audio encoder padding Currently, the amount of padding inserted at the beginning by some audio encoders, is exported through AVCodecContext.delay. However - the term 'delay' is heavily overloaded and can have multiple different meanings even in the case of audio encoding. - this field has entirely different meanings, depending on whether the codec context is used for encoding or decoding (and has yet another different meaning for video), preventing generic handling of the codec context. Therefore, add a new field -- AVCodecContext.initial_padding. It could conceivably be used for decoding as well at a later point.	10 years ago

Claudio Freire	8bbdd20a29	aacenc: Fix erasure of surround channels This was due to a miscomputation of s->cur_channel, which led to psy-based encoders using the psy coefficients for the wrong channel. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Claudio Freire	e41cd3cdeb	aacenc: Fix ticket #1784 : erasure of surround channels This was due to a miscomputation of s->cur_channel, which led to psy-based encoders using the psy coefficients for the wrong channel. Test sample attached on the bug tracker had the peculiar case of all other channels being silent, so the error was far more noticeable.

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

Michael Niedermayer	d56834201b	aacenc: fix out of array writes The value used in allocation is based on a estimate of the maximum size of the spectral coefficients multiplied with 2 and rounded up. The exact or a tighter limit should be found and used instead. But this issue shouldnt be left open until someone works on that. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Justin Ruggles	89eea6df28	aacenc: make sure to encode enough frames to cover all input samples. Currently, any samples in the final frame are not decoded because they are only represented by one frame instead of two. So we encode two final frames to cover both the analysis delay and the MDCT delay.	13 years ago
