Ganesh Ajjanagadde	07a8fbaa55	lavc/nellymoserenc: avoid wasteful pow exp2 suffices here. Some trivial speedup is done in addition here by reusing results. This retains accuracy, and in particular results in identical values with GNU libm + gcc/clang. sample benchmark (Haswell, GNU/Linux): proposed : 424160 decicycles in pow_table, 512 runs, 0 skips exp2 only: 1262093 decicycles in pow_table, 512 runs, 0 skips old : 2849085 decicycles in pow_table, 512 runs, 0 skips Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
Ganesh Ajjanagadde	68ba63ebd5	avcodec/nellymoserenc: use log2 instead of log()/M_LN2 This is likely more precise and conveys the intent better. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago

Michael Niedermayer	e36db49b7b	avcodec: Add a min size parameter to ff_alloc_packet2() This parameter can be used to inform the allocation code about how much downsizing might occur, and can be used to optimize how to allocate the packet Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago
Dyami Caliri	50833c9f7b	Fix buffer_size argument to init_put_bits() in multiple encoders. Several encoders were multiplying the buffer size by 8, in order to get a bit size. However, the buffer_size argument is for the byte size of the buffer. We had experienced crashes encoding prores (Anatoliy) at size 4096x4096.	10 years ago

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

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
