Continuous video frame grabbing feature.
In opposite to the 'xine_get_current_frame' based snapshot function
feature allow continuous grabbing of last or next displayed video
Grabbed video frames are returned in simple three byte RGB format.
Depending on the capabilities of the used video output driver video
image data is
taken as close as possible at the end of the video processing chain.
Thus a returned
video image could contain the blended OSD data, is deinterlaced,
cropped and scaled
and video properties like hue, sat could be applied.
With this patch such a decent grabbing feature is implemented for vdpau
video out driver.
If a video output driver does not have a decent grabbing implementation
is a generic fallback feature that grabs the video frame as they are
taken from the video
display queue (like the xine_get_current_frame' function).
In this case color correct conversation to a RGB image incorporating
and scaling to the requested grab size is also supported.
A more detailed description can be found in file "xine.h".
Actually this new feature is already supported by the VDR xine plugin
(with separate patches), the
VDR xineliboutput plugin and the xine atmolight post plugin.
