I am using Video Providers extensively in my project now.
I have already posted a question regarding adding Trickmode support so that
VideoProviders can support FastForward and Rewind.
The responses on this have been somewhat limited.
The next problem i have is with frame grabbing of a running video provider.
The surface that is used to render to is a virtual surface as it is owned by
embedded hardware and as such the surface is not maintained in system ram.
This means that i cannot use the Dump ability of surfaces.
I am therefore considering adding a function 'FrameGrab' to the video
provider API into which you pass a surface that you want a frame grabbed
and stored in.
This means that I can let my embedded hardware run video on the virtual
surface that it owns and i can provide a second surface that is in system
ram when I need to grab a frame. I can then use the existing methods to
dump this frame.
This allows screen shots etc to be available.
Any thoughts on this?
