Makes the code less obfuscated and fixes encoding one video stream to
several outputs.
Also use avcodec_alloc_frame() instead of allocating AVFrame on stack.
Breaks me_threshold in avconv, as motion vectors aren't passed through
lavfi. They could be copied manually, but I don't think this misfeature
is useful enough to justify ugly hacks.

Keep a per-OutputFile instance of it, thus making -t work with multiple
output files.

First, container stores only DTS and not PTS as it was believed.
Second, multiple frames in a packet store timestamp instead of position
after the frame length.

This reverts commit ac0fb5934893be554a44d2a1eb7a3bc7bf39da4a. It
causes valgrind errors which I'll want to investigate before
resubmitting this.

Old version divided it wrong, which resulted in chroma drift (visible on FATE
sample too as dirty trails left by clouds).

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.
|
|
|
|
|
| |
When using e.g. lanczos scaling, values can drop below 0, so they
should never be unsigned.

We would use the second half of the U plane buffer, rather than the
V plane buffer, to output the V plane pixels.

They were replaced by (de)muxer private options.

AVStream is no place for it and it's unused outside of ffmpeg anyway.

Change the test program to output text instead of binary files so
it can be compared easily in FATE.

This prevents random values from the stack being used as
"variables" in expressions.

For 9/10bit, it means we don't have to upscale to 16bit before
actual scaling or pixel format conversion, and thus a performance
gain.

This means that precision is retained when scaling between sample
formats with >8 bits per component (48bit RGB, 16bit grayscale,
9/10/16bit YUV).

YUV planes were marked as uint16_t, but they contained signed data.
