Not supported by all video output drivers. -``--colormatrix=<colorspace>`` - Controls the YUV to RGB color space conversion when playing video. There - are various standards. Normally, BT.601 should be used for SD video, and - BT.709 for HD video. (This is done by default.) Using incorrect color space - results in slightly under or over saturated and shifted colors. - - The color space conversion is additionally influenced by the related - options --colormatrix-input-range and --colormatrix-output-range. - - These options are not always supported. Different video outputs provide - varying degrees of support. The ``opengl`` and ``vdpau`` video output - drivers usually offer full support. The ``xv`` output can set the color - space if the system video driver supports it, but not input and output - levels. The ``scale`` video filter can configure color space and input - levels, but only if the output format is RGB (if the video output driver - supports RGB output, you can force this with ``-vf scale,format=rgba``). - - If this option is set to ``auto`` (which is the default), the video's - color space flag will be used. If that flag is unset, the color space - will be selected automatically. This is done using a simple heuristic that - attempts to distinguish SD and HD video. If the video is larger than - 1279x576 pixels, BT.709 (HD) will be used; otherwise BT.601 (SD) is - selected. - - Available color spaces are: - - :auto: automatic selection (default) - :bt.601: ITU-R BT.601 (SD) - :bt.709: ITU-R BT.709 (HD) - :bt.2020-ncl: ITU-R BT.2020 non-constant luminance system - :bt.2020-cl: ITU-R BT.2020 constant luminance system - :smpte-240m: SMPTE-240M - -``--colormatrix-input-range=<color-range>`` - YUV color levels used with YUV to RGB conversion. This option is only - necessary when playing broken files which do not follow standard color - levels or which are flagged wrong. If the video does not specify its - color range, it is assumed to be limited range. - - The same limitations as with --colormatrix apply. - - Available color ranges are: - - :auto: automatic selection (normally limited range) (default) - :limited: limited range (16-235 for luma, 16-240 for chroma) - :full: full range (0-255 for both luma and chroma) - -``--colormatrix-output-range=<color-range>`` - RGB color levels used with YUV to RGB conversion. Normally, output devices - such as PC monitors use full range color levels. However, some TVs and - video monitors expect studio RGB levels. Providing full range output to a - device expecting studio level input results in crushed blacks and whites, - the reverse in dim gray blacks and dim whites. - - The same limitations as with ``--colormatrix`` apply. - - Available color ranges are: - - :auto: automatic selection (equals to full range) (default) - :limited: limited range (16-235 per component), studio levels - :full: full range (0-255 per component), PC levels - - .. note:: - - It is advisable to use your graphics driver's color range option - instead, if available. - -``--colormatrix-primaries=<primaries>`` - RGB primaries the source file was encoded with. Normally this should be set - in the file header, but when playing broken or mistagged files this can be - used to override the setting. By default, when unset, BT.709 is used for - all files except those tagged with a BT.2020 color matrix. - - This option only affects video output drivers that perform color - management, for example ``opengl`` with the ``srgb`` or ``icc-profile`` - suboptions set. - - If this option is set to ``auto`` (which is the default), the video's - primaries flag will be used. If that flag is unset, the color space will - be selected automatically, using the following heuristics: If the - ``--colormatrix`` is set or determined as BT.2020 or BT.709, the - corresponding primaries are used. Otherwise, if the video height is - exactly 576 (PAL), BT.601-625 is used. If it's exactly 480 or 486 (NTSC), - BT.601-525 is used. If the video resolution is anything else, BT.709 is - used. - - Available primaries are: - - :auto: automatic selection (default) - :bt.601-525: ITU-R BT.601 (SD) 525-line systems (NTSC, SMPTE-C) - :bt.601-625: ITU-R BT.601 (SD) 625-line systems (PAL, SECAM) - :bt.709: ITU-R BT.709 (HD) (same primaries as sRGB) - :bt.2020: ITU-R BT.2020 (UHD) - - Demuxer ------- |
