If the Direct3D device is "lost" (e,g, when minimizing mplayer, or when
another application uses Direct3D exclusive mode), we free it and try to
recrate the device. This can fail, and may fail for an extended period of
time, until D3D is available again and the device can be created. So we
basically have to provide all VO functionality while d3d_device is NULL.
Don't terminate if device creation fails, and re-add the NULL checks that
were removed in the commit "vo_direct3d: refactor D3D initialization and
reconfigure code".
If mplayer calls the VO's config() while the D3D device can not be
created, the VO will return an error and mplayer will terminate.
config() is typically called when new files are played, when ordered
chapter boundaries are crossed, or on other events.
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
- libfontconfig
- 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.
