* avcodec/alsdec: fix max bits in ltp prefix codeUmair Khan2016-03-12
| | | | | | | | | | | The maximum number of bits int the prefix code for p(0) is 4. By setting it as 3, we were missing the last 0 bit. This fixes bug #4715 present on the trac.

* mips: add support for R6Vicente Olivert Riera2016-03-09
| | | | | | | | | | | Understanding the mips32r6 and mips64r6 ISAs in the configure script is not enough. In order to have full support for MIPS R6 in FFmpeg we need to be able to build it, and for that we need to make sure we don't use incompatible assembler code which makes the build fail. Ifdefing the offending code is sufficient to fix the problem. Signed-off-by: Vicente Olivert Riera <Vincent.Riera@imgtec.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* vc2enc: do not allocate packet until exact frame size is knownRostislav Pehlivanov2016-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | This commit solves most of the crashes and issues with the encoder and the bitrate setting. Now the encoder will always allocate the absolute lowest amount of memory regardless of what the bitrate has been set to. Therefore if a user inputs a very low bitrate the encoder will use the maximum possible quantization (basically zero out all coefficients), allocate a packet and encode it. There is no coupling between the bitrate and the allocation size and so no crashes because the buffer isn't large enough. The maximum quantizer was raised to the size of the table now to both keep the overshoot at ridiculous bitrates low and to improve quality with higher bit depths (since the coefficients grow larger per transform quantizing them to the same relative level requires larger quantization indices). Since the quantization index start follows the previous quantization index for that slice, the quantization step was reduced to a static 1 to improve performance. Previously with quant/5 the step was usually set to 0 upon start (and was later clipped to 1), that isn't a big change. As the step size increases so does the amount of bits leftover and so the redistribution algorithm has to iterate more and thus waste more time.
