This affects property format strings like they are used in the
"show_text" input command, for --playing-msg, and other places.
To quote the documentation comment on m_properties_expand_string():
${NAME} is expanded to the value of property NAME.
If NAME starts with '=', use the raw value of the property.
${NAME:STR} expands to the property, or STR if the property is not
available.
${?NAME:STR} expands to STR if the property is available.
${!NAME:STR} expands to STR if the property is not available.
STR is recursively expanded using the same rules.
"$$" can be used to escape "$", and "$}" to escape "}".
"$>" disables parsing of "$" for the rest of the string.
Most importantly, "?(property:str)" becomes "${?property:str}".
Make the simple fallback case easier, e.g. "${property:fallback}"
instead of "${property}?(!property:fallback)".
Add the ability to escape the format meta characters. "$" is used for
escaping, because escaping with "\" is taken by the commands parser in
the layer below. "$>" can be used to disable interpretation of format
strings (of course escapes by the commands parser can't be canceled).
By default, properties which are unavailable or don't exist are turned
into a string signaling the status (e.g. "(unavailable)"), instead of
an empty string. If an empty string is desired, this has to be done
explicitly: "${property:}" (the fallback part is an empty string). Raw
properties still return an empty string on error.
m_properties_expand_string() now returns a talloc'ed pointer, instead of
a malloc'ed one.

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.
