* lavc: Drop exporting 2-pass encoding statsVittorio Giovara2015-12-07
| | | | | | | | | | | | | | These variables are coming from mpegvideoenc where are supposedly used as bit counters on various frame properties. However their use is unclear as they lack documentation, are available only from a very small subset of encoders, and they are hardly used in the wild. Also frame_bits in aacenc is employed in a similar way. Remove this functionality from AVCodecContex, these variable are mostly frame properties, and too few encoders support setting them with anything useful.

* lavc: use a separate field for exporting audio encoder paddingAnton Khirnov2014-10-13
| | | | | | | | | | | | | | 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.

* aacenc: Fix erasure of surround channelsClaudio Freire2013-05-14
| | | | | | | 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>

* floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | | 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.

* aacenc: make sure to encode enough frames to cover all input samples.Justin Ruggles2012-01-30
| | | | | | 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.

* aacenc: Fix determination of Mid/Side Mode.Nathan Caldwell2011-06-29
| | | | | | | | | In adjust_frame_information(), msc is incremented for each sfb in each sub-window then compared against max_sfb which is for a single sub-window. This resulted in frames using EIGHT_SHORT_SEQUENCE where the first few sub-windows increment msc to a value that results in ms_mode == 2. Even though only some of the bands are actually using Mid/Side.
