With cli usage the decoder might have not set the colorspace during
encoder init, manual colorspace override might be needed in such
cases.

Makes it easier to recreate an AVCodecContext for ATRAC3+ decoding,
which is needed in multimedia frameworks, as well as in general cases
where demuxing and decoding are separate entities.

parsed VUI values to known valid ones, and the second one passes

OK. It's just 60 kilobytes but I guess I'll cut it to three frames or so.

The failures on various architectures and compilers on the RGB(A)
tests seem to have been because of one-off YCbCr-RGB conversion
results. This should make the conversion results match on most if
not all code paths.

These patches contain both a Ut Video encoder that creates
files that the official reference implementation likes, and
that in most cases decode just fine on the libavcodec decoder
as well (more on this later*), as well as FATE tests for the
encoder.

This patch is a GSoC qualification task of mine, which was to
implement slice-based multithreading for the Ut Video lossless
video format.
Unfortunately, having had this patch tested speed-wise by Kostya
Shishkov, it seems like slice-based multithreading ends up slower
than frame-based, and thus
.
Thank you for devoting the time to taking a look at these patches.
