With the help of this mailing list I wrote a directfb app for the
Syabas NMT family that has been working quite well for several users
for months. I am trying something new but I have run into a situation
where with component 1280x720 output a Clear(0,0,0,0) doesn't do
anything. The code is simply
DFBCHECK (primary->Clear(primary,0,0,0,0));
DFBCHECK (primary->Flip(primary,NULL, DSFLIP_WAITFORSYNC));
DFBCHECK (primary->Clear(primary,0,0,0,0));
and no errors are returned. I have checked the clipping region and
it still returns a DFBRegion of 0 0 1279 719. Since I can hear audio
I believe the MainVideo layer would show if I could clear layer 0
somehow and it does works in PAL and NTSC resolution.
Any ideas or tips on things to try?
Here are the layers
Layer (00) OSD (primary layer)
Type: GRAPHICS
Caps: SURFACE ALPHACHANNEL FLICKER_FILTERING SRC_COLORKEY
GetPixel 418c04|200808
Layer (01) BGND
Type: GRAPHICS
Caps: SURFACE
GetPixel 200808|200808
Layer (02) MainVideo
Type: VIDEO
Caps: SCREEN_LOCATION BRIGHTNESS CONTRAST HUE SATURATION
SOURCES SCREEN_POSITION SCREEN_SIZE
Sources: Bogus source for main v
Layer (03) 2ndVideo
Type: GRAPHICS VIDEO
Caps: SURFACE SCREEN_LOCATION BRIGHTNESS CONTRAST HUE
SATURATION LEVELS SOURCES SCREEN_POSITION SCREEN_SIZE
Sources: Bogus source for second, Bogus source for second
Thanks in advance.
