The playback status symbol in the OSD status display on video (such as displayed when seeking or with the show_progress input command) sometimes kept displaying the last seek, without resetting the symbol. (For example: disable the OSD, seek, enable the OSD, run show_progress; but also other cases.) The main reason for that was the code clearing the OSD bar is also responsible for clearing the osd_function (which stores the playback symbol). If no OSD bar was set, the osd_function was never reset. Fix by always setting the timer for clearing the OSD bar and the osd_function whenever the osd_function is set. Clearing the OSD bar when it wasn't set is OK. If the OSD bar is set some time after osd_function is set, the timer is overwritten - that's a good thing, as it makes both disappear from the screen at exactly the same time. Always reset osd_function to 0 and determine the playback status explicitly from mpctx->paused when displaying the status on screen.
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.
