With all the various refactorings that have happened over the years,
the current pts logic is very broken for non-trivial cases (ie: ones
where not every frame/field has a meaningful pts assocated with it).
Generally, we do not want to write AV_NOPTS_VALUE as the output
timestamp, regardless of anything else. It's better to pass zero
if there's no other information.
Additionally, interlaced content where the decoder returns each field
separately can result in the first field carrying the timestamp and
the second having AV_NOPTS_VALUE. It's clearly wrong to overwrite
the valid timestamp.
So, let's just never write AV_NOPTS_VALUE into an output frame.
Empirically, this fixed playback of interlaced mpeg2 and h.264 and
mpeg4-asp with packed b-frames in an avi container.
Using lfg was an overkill in this case where the random numbers
were only used for encoder descisions. Should increase result
uniformity between different FPUs and gives a slight speedup.

The spec says:
"Mandatory elements with a default value may be left out of the file. In the absence
of a mandatory element, the element's default value is used."

Also filter filename and mimetype entries, as they are standard elements

The parser for the outdef will accept a negative value for the first
named channel's gain. As negative values effectively only invert the
phase of the signal, and not negate the level, the gains' absolute
values must be used to correctly accumulate the levels.

The optimizations of mipsdsp are not supported by all loongson cpu.
The optimizations of mipsfpu and mipsdspr2 maybe supported by 3A2000/3A3000/3A4000 but not tested yet.
Loongson only support mmi (loongSIMD) optimizations now.

The slice index expected by D3D11VA is the one from the texture not from the
array or texture/slices.
In VLC the slices we provide the decoder don't start from 0 and thus pictures
appear in bogus order. With possible crashes and corruptions when using an
invalid index.

lavc: export the timestamps when decoding in AVFrame.pts
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
Decoders have previously not used AVFrame.pts, and with the upcoming
deprecation of pkt_pts (in favor of pts), this would lead to an errorneous
interpration of timestamps.
This fixes a long-standing issue where running FATE in parallel could result
in the terminal being left misconfigured, particularly if a test failed or
was canceled wtih ^C.
