Rewrite control of the colorspace and input/output level parameters used in YUV-RGB conversions, replacing VO-specific suboptions with new common options and adding configuration support to more cases. Add new option --colormatrix which selects the colorspace the original video is assumed to have in YUV->RGB conversions. The default behavior changes from assuming BT.601 to colorspace autoselection between BT.601 and BT.709 using a simple heuristic based on video size. Add new options --colormatrix-input-range and --colormatrix-output-range which select input YUV and output RGB range. Disable the previously existing VO-specific colorspace and level conversion suboptions in vo_gl and vo_vdpau. Remove the "yuv_colorspace" property and replace it with one named "colormatrix" and semantics matching the new option. Add new properties matching the options for level conversion. Colorspace selection is currently supported by vo_gl, vo_vdpau, vo_xv and vf_scale, and all can change it at runtime (previously only vo_vdpau and vo_xv could). vo_vdpau now uses the same conversion matrix generation as vo_gl instead of libvdpau functionality; the main functional difference is that the "contrast" equalizer control behaves somewhat differently (it scales the Y component around 1/2 instead of around 0, so that contrast 0 makes the image gray rather than black). vo_xv does not support level conversion. vf_scale supports range setting for input, but always outputs full-range RGB. The value of the slave properties is the policy setting used for conversions. This means they can be set to any value regardless of whether the current VO supports that value or whether there currently even is any video. Possibly separate properties could be added to query the conversion actually used at the moment, if any. Because the colorspace and level settings are now set with a single VF/VO control call, the return value of that is no longer used to signal whether all the settings are actually supported. Instead code should set all the details it can support, and ignore the rest. The core will use GET_YUV_COLORSPACE to check which colorspace details have been set and which not. In other words, the return value for SET_YUV_COLORSPACE only signals whether any kind of YUV colorspace conversion handling exists at all, and VOs have to take care to return the actual state with GET_YUV_COLORSPACE instead. To be changed in later commits: add missing option documentation. |

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.
