When not using direct rendering, vd_ffmpeg created an mp_image struct before calling libavcodec decoder, so that possible slice support could be checked from the mpi_image and output would be ready for slice-drawing calls. However, this behavior is unsound with decoders that can change output size, as the parameters can change after the mp_image was created. Disable the code creating the mp_image at that point, which also disables use of slices in this case. Slices are disabled with threading anyway, so I think trying to add workarounds to support them is not a high priority. I think this code has always been buggy, but before common thread use it was rarely executed because the direct-rendering case was used instead.
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.
