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

Justin Ruggles e9cda85351 avcodec: add duration field to AVCodecParserContext 
This will allow parsers to export the duration of the current frame being
output, if known, instead of using AVCodecContext.frame_size.

Justin Ruggles 469d2a8e8e libmp3lame: remove outdated comment. 
We now require at least libmp3lame 3.98.3.
lame_encode_buffer_interleaved() still doesn't work for mono, but it does not
"die"; it just expects a stereo interleaved buffer.

Anton Khirnov 8c8c7b5e37 zmbvenc: move header writing to the end of encode_frame(). 
This makes switching to encode2() simpler, because it allows us to know
exactly how large should the output buffer be before we start writing
into it.

Anton Khirnov 5455384219 mpegvideo_enc: force encoding delay of at least 1 frame when low_delay=0 
This allows the following commit to extrapolate better dts for the first
frame. Pts difference between the first two frames is reused as the
difference between pts and dts of the first frame.

Kostya Shishkov 6d702dc072 proresenc: force bitrate not to exceed given limit 
Apple ProRes Format Specifications mentions target data size for every frame,
so make sure frame meets it. This also allows encoder to demand much smaller
packet sizes for output.

Ronald S. Bultje c742ab4e81 vc1parse: call vc1_init_common(). 
The parser uses VLC tables initialized in vc1_common_init(), therefore
we should call this function on parser init also.

Ronald S. Bultje 9d3050d3e9 wma: don't return 0 on invalid packets. 
Return 0 means "please return the same data again", i.e. it causes an
infinite loop. Instead, return an error.

Ronald S. Bultje 74699ac8c8 mjpegb: don't return 0 at the end of frame decoding. 
Return 0 indicates "please return the same data again", i.e. it causes
an infinite loop. Instead, return that we consumed the buffer if we
finished decoding succesfully, or return an error if an error occurred.

Ronald S. Bultje 3e13005cac mp3on4: require a minimum framesize. 
If bufsize < headersize, init_get_bits() will be called with a negative
number, causing it to fail and any subsequent call to get_bits() will
crash because it reads from a NULL pointer.
