a67c061e0f lavf: add avformat_find_stream_info()
It supports passing options to codecs.

0b950fe240 lavc: introduce avcodec_open2() as a replacement for avcodec_open().
Adds support for decoder-private options and makes setting other options
simpler.

e35c674d13 alsa: limit buffer_size to 32768 frames.
In testing, the file output plugin gave a max buffer size of about 20 million
frames, which is way more than what is really needed and causes a memory
allocation error on my system.

8bfd7f6a47 alsa: fallback to buffer_size/4 for period_size.
buffer_size/4 is the value used by aplay. This fixes output to null
devices, e.g. writing ALSA output to a file.

f98c9fb27d mpeg1video: don't abort if thread_count is too high.
Instead, just decrease it to a valid value and use that.

99fecc64b0 gxf: Fix 25 fps DV material in GXF being misdetected as 50 fps
Set DV packet durations using fields_per_frame.
This requires turning gxf_stream_info into the demuxer's context for access to the value in gxf_packet().
Since MPEG-2 seems to work fine this done only for DV.

7d7bacf0f1 swscale: fix overflow in 16-bit vertical scaling.
We operated on 31-bits, but with e.g. lanczos scaling, values can
add up to beyond 0x80000000, thus leading to output of zeroes. Drop
one bit of precision fixes this.

bf2cba4532 swscale: fix crash in 8-bpc bilinear output without alpha.
We accessed the alpha array even it wasn't used and didn't
exist, hence leading to a NULL pointer segfault.

f44d50a94c swscale: fix 16-bit horizontal scaling underflow.
When using e.g. lanczos scaling, values can drop below 0, so they
should never be unsigned.

42d622fab3 swscale: fix 16-bit scaling when output is 8-bits.

V plane buffer, to output the V plane pixels.

a726d7fd4e AVOptions: in av_opt_find() don't return named constants unless unit is specified.
That is, unless the caller explicitly asks for them.

'loop' flag in AVCodecContext.
