Speed up the overall compilation time.

|
|

This reduces inter-library dependencies.
|
|
|
|
|
| |
The field still remains in MpegEncContext because it is used by the
mpeg4 decoder.
|
| |
|
|
|
|
|
|
| |
Also add a note about the feature in the changelog.

Use the intensity-compensated reference frame for subsequent
fields/B-frames.
Since we currently don't change the reference frame we have to
maintain lookup tables for intensity compensation in the following
dependent frames.

This simplifies the code since copying MVs to the reference is not needed
anymore (and maybe something about fixing artifacts).
Also remove the unused mv_f_last.
Fixes a small number of artifacts in black_screen_VC-1.mkv
and several more artifacts in other videos.

The init functions marked as av_cold have to be executed in any case,
so there is no gain from trying to mark paths leading to such functions
as unlikely.

It does not help as an abstraction and adds dsputil dependencies.

This is a preparatory step for the MSS2 decoder which needs to use
the WMV9 decoder to decode some kinds of frames.

This fixes standalone compilation of the VC-1 parser.
|
|
|
|
|
|
|
|
| |
The parser uses VLC tables initialized in vc1_common_init(), therefore
we should call this function on parser init also.

IDCT coefficients are read transposed, but simple_idct does not expect
this. Therefore, only do tranposed coefficient reading if we're not
using simple_idct.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.' to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
