PlayMovie on a Screen

Hi, I know there are a few workarounds for displaying on a screen, but I can't get a Movie played fullscreen with hardware-interpolation. I get jerky playback and tearing, because the playback of the movie is in a window and it seems to use gdi for output!

Fred, can you please use DirectVideo or DirectShow (uses Hardware-capabilities of the gfx-card) for this?

Yours

Open a screen then try this:

Code: Select all

;-PlayAvi
playavi  :
FlipBuffers()
ClearScreen(0,  0, 0)
FlipBuffers()

If InitMovie()
  LoadMovie(0,  #gfx  + "title.avi")
  ClearScreen(0,  0, 0)
  Delay(1000)
  PlayMovie(0,  ScreenID())
  Repeat
    Delay(1)
  Until MovieStatus()=MovieLength() - 2
  FreeMovie(0)
  ClearScreen(0,  0, 0)
EndIf
Return

Hi Num3,

your example works exactly, how I play my movies at the moment! But it doesn't use the Hardware-Stretch from the graphics-card! It simply scales the output and pageflipping is not performed during the vertical-blank and causes a lot of tearing on the screen!

So, what's your point with your example?

Greetings

The point was to help you..

About the full screen player with hardware support, I will investigate this.

The jerkyness can be due to a lot of things...
The AVI CODEC for one....
Problems with the movie stream....
Bad encoding...

For my game i'm using a 640x320x24bit divx intro and it plays smooth....

I tried with a simple Mpeg1 Stream, because I want to have movie-support without the need to install a codec. Even Windows 98 can play .mpg files! The tearing has nothing to do with the codec. The problem is, that no pageflipping is used.
