7a851153d3 mpegvideo: convert mpegvideo_common.h to a .c file
This file defines a single, huge function, MPV_motion(), which
although being declared inline is not actually inlined by the
compiler (for good reason).  There is thus no sense in defining
this function in a header file, resulting in multiple copies of
it in the final library.

17fad33f81 Change all uses of restrict to use av_restrict instead.
Defining restrict results - for some compilers - in changing other
uses of the restrict keyword also, e.g. __declspec(restrict) gets
changed to __declspec(__restrict) on MSVC. This causes compilation
failures. Therefore, using a private namespace macro instead is
more reliable and robust.

5e50a5724b Revert "removing lowres support"
There have been multiple user complaints about loosing this feature
while its not clear the 3% speedloss claims where real or fabricated.
My own testing indicates no statistically significant speed difference
both with mpeg2 and mpeg4, and if at all the code with lowres support
is a tiny bit faster than without.

This reverts commit 92ef4be4ab, reversing
changes made to 2e07f42957.

70d54392f5 lowres2 support.
The new lowres support is limited to decoders where lowres decoding

I was not able to measure any speed difference, but if one is found
the 2-3 lines that might affect speed can be made compile time conditional

9b6aafba6c mpegvideo: fix invalid memory access for small video dimensions
When either video dimension is only one macroblock, subtractions
based on v_edge_pos and the macroblock size may be negative. In
that situation, an unsigned comparison isn't sufficent to test for
MV overruns, because a limit of (unsigned)-1 will let any other
value pass.

3ab7700018 mpegvideo: claim ownership of referenced pictures
Under certain conditions pictures could be released before they were
returned with frame-threading. Broken mv computation in the upcoming
rv34 frame-threading patch was caused by this.

To prevent contexts from running out of available pictures the loop
releasing "unused" pictures has to be run for B frames too.

This reverts commit 4f820131fa.

It is better to abort() than to have remotly exploitable arbitrary code
execution bugs. Even more so that this abort has never been triggered
by any input people threw at it.
If after more extensive testing its removial is found safe we can remove
the abort() later.

80469eafb7 mpegvideo: fix invalid picture unreferencing.
Mpegvideo would free frames as soon as they're not the next or prev
picture. This is fine for a single-threading model, but fails miserably
in a system where pictures can be referenced (as e.g. last/prev pic)
in other threads. Keeping track of ownership of pictures keeps image
references (e.g. motion vectors, or the reference of a motion vector)
alive as long as the picture data itself is alive.

This also happens to fix make THREADS=[3-16] fate-vsynth[12]-error.

This is required since mpegvideo.h:Picture now contains an embedded

900321b08c Don't mark generated dummy frame output from mpeg1/2 decoder as keyframe.
We use this flag to tell when to assume decoded data is free
from artifacts after a seek. The mpeg1/2 decoder will generate
a dummy frame if decoding is started on a non keyframe. This
will sadly be output from decoder to player and displayed
as a gray screen.

Reinhard Tartler
737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

00d1e96bf4 H.264 decode: support cropping up to 28 pixels in interlaced mode.
Contrary to progressive, just being able to crop up to 14/15 pixels
is not enough to encode all supported resolutions, and the new
behaviour is also consistent with e.g. MPEG-2 etc.

8bdf11815c Fixed mpeg12 top field first flag value with field picture encoding.
The relevent extract of the iso 13818-2 about the value of the syntaxical
element top_field_first of the Picture Coding Extension is:

"top_field_first -- The meaning of this element depends upon picture_structure,
progressive_sequence and repeat_first_field.
[...]
In a field picture top_field_first shall have the value '0', and the only field
output by the decoding process is the decoded field picture."

92c6a099ba H264 DXVA2 implementation
It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
 It is implemented by using AVHWAccel API. It has been tested successfully
for some time in VLC using an nvidia card on Windows 7.

 To compile it, you need to have the system header dxva2api.h (either from
microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h)
 The generated libavcodec.dll does not depend directly on any new lib as
the necessary objects are given by the application using FFmpeg.

79db7ac6ef Fix memory leak in h264 decoder. allocated_edge_emu_buffer was being allocated
in both mpegvideo and h264 decoder. Fixed by allowing all (master and duplicate)
contexts to fully initialize in MPV_frame_start and copying these into
H264Contexts.
