Viewer using buffer like youtube videos

Post by JnZn558 »

does the cache encoding using a buffer like youtube videos? I had a test on vmware with resolution 3840 x 3072, on the viewe site it updates stepwise downto bottom. could it be possible to delay the updates and show the new updates at once? I mean remove this stepwise method? could directx realise this?

cache encoding= save under ( some simple protocol that was used in X)
save (120,120,200,200)
update rect (120,120,200,200)

if same rectangle is used ( maximize,minimize,maximize)
server check if it exist in cache and send the message to the viewer
update (120,120,200,200) from cache.

only 1 level deep, just keep the last rectangle.

Are you using latest viewer ?
With or without directx [v] all changes are only update after a cycle.
bitmap is updated for each rectangle
rectangles are added to the region
at the end invalidateregion is called
this send the wm_paint

If you move a window, the OS also send a wm_paint
(refresh window)
If you move the viewer window you still see the updates per rectangle.
