Plain C, x86-32 and -64 have been tested and should work, other
archs that had asm optmizations in swscale likely will need some fixes
to either fall back on C if SWS_BITEXACT is set or make the asm match C.
This also disables the PAL8 test as neither swscale nor the old scaler
really support PAL8 output, imgconvert supported a fixed 666 palette
as output and swscale supports fixed 884 and 422.

The matroska demuxer now index every streams so seek on stream 1 now works.

residuals, Note this does not change RGB32 as we need to check this
against some decoder that supports it.

This change is due to r14590.
The AVPacket position now points to the first byte of the actual
packet data in the file. It previously pointed to the EBML element
ID preceding packet data.

contains the first picture startcode that commences in the PES
packet, instead of the first access unit that commences in the
PES packet. Fix the parser to
handle that properly. This was a very long standing bug ...
The change to the seek regressions is because the mpeg ts muxer
stores too many invalid and randomized timestamps which overflow
the 4 entry buffer we use in the parser.

The PSP MP4 format requires an AAC audio stream, so until
we have an AAC encoder we cannot test this format.
The existing test is broken and does not actually use the
PSP format.

which caused some to be lost ...).
I wonder why FATE did not pick this up?

and the information needed to guess the duration only becomes known at a later packet.

This only removes 2 bytes from MP3 and MP2 currently.
Up to 4 could be removed from MP3/MP2 though this might need a 2pass muxer.
Primitive code to remove headers from MPEG-1/2/4 is there too but for the
single file I tried it on (the one in the regression tests), it was a loss
because all video frames were >4096 byte, so that it is disabled ATM.

these were wrong (in pts vs dts sense) when b frames were in use
they were also wrong if the average framerate was smaller than 1/timebase
resulting in totally wrong final bitrate

flag for diagonal interpolation
the primary reason for this change is that previously MC up to 1/4 pel
matched H.264 exactly and that increases the risk of stumbling over
patents
secondly this allows 0.10 db or more quality gain by choosing a longer
filter and the filter could also be chosen optimally for each frame
though that of course would cause speed loss at the decoder and encoder
side ...

perform interpolation steps in such an order that halfpel interpolation
could be done per picture
this also makes mc_block() match h.264 for the 1/4 pel cases so that the
use of the h264 functions for some cases does not introduce a fantastic mess
