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.

but it used to do it only for h264 codec.
Allow it for other codecs, as mpeg2 and mpeg4 also set this flag.

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."

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the

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.

because it contains motion code.
