rawvideo is a rather primitive demuxer that doesn't implement track switching. The problem was that during track switching the demuxer implementations normally set the stream IDs in order to do the switch, and since rawvideo obviously didn't do that, so the current stream in ds->sh / demuxer->video->sh was set to NULL. (The frontend always assumes track switching is successful, which is a reasonable assumption - failing due to missing video codecs etc. is in separate codepaths.) Later, demux_rawvideo_fill_buffer() in demux_rawvideo.c tried to dereference the NULL stream and crashed. Other trivial single-stream demuxers worked fine, because they didn't try to access ds->sh.
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.
