wm4 6bea013e27 screenshot: hack against w/width confusion
struct mp_image has two sets of size members: width/height and w/h. It's
not even sure which one of these is the ACTUAL dimension, and which is
the "stored" or "visible" dimension. vf_get_image() (a core function for
video filters) does something confusing with the sizes, and often sets
up cropped versions of other filter's image buffers. The screenshot code
uses w/h to store the display size for anamorphic video, while
width/height is the size of the pixel data. The draw_bmp.c code, as well
as sws_utils.c, always use w/h for the size of the pixel data.

It's an unholy mess, and the screenshot code potentially breaks it even
more. Work that around with a hack, until we hopefully clean up
mp_image and the video filter code.

README

Compiling with full features requires development files for several
external libraries. Below is a list of some important requirements. For
more information see the output of './configure --help' for a list of options,
or look at the list of enabled and disabled features printed after running
'./configure'. If you think you have support for some feature installed
but configure fails to detect it, the file config.log may contain information
about the reasons for the failure.

Libraries specific to particular video output methods
(you'll want at least one of VDPAU, GL or Xv):
 - libvdpau (for VDPAU output, best choice for NVIDIA cards)
 - libGL (OpenGL output)
 - libXv (XVideo output)
general:
 - libasound   (ALSA audio output)
 - various general X development libraries
 - libfreetype (for libass)
 - libfontconfig (for libass)
 - libass
 - FFmpeg libraries (libavutil libavcodec libavformat libswscale libpostproc)

Most of the above libraries are available in suitable versions on normal
Linux distributions. However FFmpeg is an exception (distro versions may be
too old to work at all or work well). For that reason you may want to use
the separately available build wrapper that first compiles FFmpeg libraries
and libass, and then compiles the player statically linked against those.
