bool VideoOutputD3D::Init ( int  width,
int  height,
float  aspect,
WId  winid,
int  winx,
int  winy,
int  winw,
int  winh,
WId  embedid = 0 
) [virtual]

Performs most of the initialization for VideoOutput.

void VideoOutputD3D::PrepareFrame ( VideoFrame *  buffer,
FrameScanType  t 
) [virtual]

Implements VideoOutput.

void VideoOutputD3D::ProcessFrame ( VideoFrame *  frame,
OSD *  osd,
FilterChain *  filterList,
NuppelVideoPlayer *  pipPlayer 
) [virtual]

Implements VideoOutput.

bool VideoOutputD3D::InputChanged ( const QSize &  input_size,
float  aspect,
MythCodecID  myth_codec_id,
void *  codec_private 
) [virtual]

Tells video output to discard decoded frames and wait for new ones.

Bug:
We set the new width height and aspect ratio here, but we should do this based on the new video frames in Show().

Draws non-video portions of the screen.

Parameters:
sync if set any queued up draws are sent immediately to the graphics context and we block until they have completed.

Implements VideoOutput.
