Force color range for the output video frame.
|
||||||
|
|
||||||
|
The @code{setrange} filter marks the color range property for the
|
||||||
|
output frames. It does not change the input frame, but only sets the
|
||||||
|
corresponding property, which affects how the frame is treated by
|
||||||
|
following filters.
|
||||||
|
|
||||||
|
The filter accepts the following options:
|
||||||
|
|
||||||
|
@table @option
|
||||||
|
|
||||||
|
@item range
|
||||||
|
Available values are:
|
||||||
|
|
||||||
|
@table @samp
|
||||||
|
@item auto
|
||||||
|
Keep the same color range property.
|
||||||
|
|
||||||
|
@item unspecified, unknown
|
||||||
|
Set the color range as unspecified.
|
||||||
|
|
||||||
|
@item limited, tv, mpeg
|
||||||
|
Set the color range as limited.
|
||||||
|
|
||||||
|
@item full, pc, jpeg
|
||||||
|
Set the color range as full.
