Specifying a string option with no parameter, as in "--dumpfile" with no '=', erroneously set the corresponding variable to NULL. Fix this to give an error about missing parameter instead. Suboption parsing explicitly treated empty option values as if the option had been specified with no value (no '='). Thus it was not possible to specify empty strings as values. I think this behavior was originally added only because of other limitations in the old implementation. Remove it, so that suboptions now behave the same as top-level ones in this regard. Document the NULL-distinguishing property of bstrdup0() that the code depends on, and also make bstrdup() behave consistently.
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.
