The option type m_option_type_rel_time was completely broken. It interpreted everything starting with a number as percent position. This is because sscanf() semantics are idiotic (trailing string doesn't need to be matched), and due to my own idiocy this was overlooked when testing. Fix by considering sscanf() evil and not using it. (bstr_sscanf() is a straight wrapper around sscanf()). Even if the percent code was fixed, there was another bug: it always interpreted times as negative (starting from end for --start). Fix the basic logic.
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.
