Derek Buitenhuis 480b133e6f wavpack: Don't shift minclip/maxclip 
Since we are clipping before we shift the values to
16 or 32 bits, we should not shift the min/max clip
values to compensate.

Fixes 8 and 24 bit lossy decoding.

Anton Khirnov ff311c0918 lavc: drop encode() support for video. 
All video encoders have been converted to encode2(), all new encoders
should also use only encode2().

Anton Khirnov 2257f66ec5 lavc: drop libdirac encoder. 
Libschroedinger is the preferred way to encode dirac video now, it
produces better output and has a nicer API.

Ronald S. Bultje 01cb62aba2 lcl: don't overwrite input memory. 
If the PNG filter is enabled, a PNG-style filter will run over the
input buffer, writing into the buffer. Therefore, if no zlib compression
was used, ensure that we copy into a temporary buffer, otherwise we
overwrite user-provided input data.

Christophe GISQUET b5696ff2b8 prores: use natural integer type for the codebook index 
The operations that use it require it to be promoted to a larger (natural)
type and thus perform sign extension on it.

While an optimal compiler may account for this, gcc 4.6 (for x86 Windows)
fails. Using the natural integer type provides a 2% speedup for Win64
and 1% for Win32.

Ronald S. Bultje 3ab9a2a557 rv34: change most "int stride" into "ptrdiff_t stride". 
This prevents having to sign-extend on 64-bit systems with 32-bit ints,
such as x86-64. Also fixes crashes on systems where we don't do it and
arguments are not in registers, such as Win64 for all weight functions.

Justin Ruggles 770a5c6d02 adpcmenc: Use correct frame_size for Yamaha ADPCM. 
Output packet size should match avctx->block_align. The target output packet
size is 1024 bytes.
Before:
mono   - 1024 samples -> 512 bytes
stereo - 2048 samples -> 2048 bytes
After:
mono   - 2048 samples -> 1024 bytes
stereo - 1024 samples -> 1024 bytes
