Has the same sub-properties as ``video-params``.
``video-frame-info``
Approximate information of the current frame. Note that if any of these
are used on OSD, the information might be off by a few frames due to OSD
redrawing and frame display being somewhat disconnected, and you might
have to pause and force a redraw.
Sub-properties:
``video-frame-info/picture-type``
``video-frame-info/interlaced``
``video-frame-info/tff``
``video-frame-info/repeat``
``fps``
Container FPS. This can easily contain bogus values. For videos that use
modern container formats or video codecs, this will often be incorrect.
