Frame rate information is mostly irrelevant for playback, but it's needed at least to convert frame numbers used in some subtitle formats (like MicroDVD) into timestamps. Libavformat stopped making up a frame rate if no "reliable" information is available (commit 7929e22bd "lavf: don't guess r_frame_rate from either stream or codec timebase", 1.5 months ago). This caused a regression with AVI files and MicroDVD subtitles. Add a heuristic similar to what libavformat used to have, to make up FPS values which should work at least for the AVI+MicroDVD use case.
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.
