示例1: IntSize
void
DOMHwMediaStream::SetImageSize(uint32_t width, uint32_t height)
{
#ifdef MOZ_WIDGET_GONK
OverlayImage::Data imgData;
imgData.mOverlayId = mOverlayImage->GetOverlayId();
imgData.mSize = IntSize(width, height);
mOverlayImage->SetData(imgData);
#endif
SourceMediaStream* srcStream = GetInputStream()->AsSourceStream();
StreamBuffer::Track* track = srcStream->FindTrack(TRACK_VIDEO_PRIMARY);
if (!track || !track->GetSegment()) {
return;
}
#ifdef MOZ_WIDGET_GONK
// Clear the old segment.
// Changing the existing content of segment is a Very BAD thing, and this way will
// confuse consumers of MediaStreams.
// It is only acceptable for DOMHwMediaStream
// because DOMHwMediaStream doesn't have consumers of TV streams currently.
track->GetSegment()->Clear();
// Change the image size.
const StreamTime delta = STREAM_TIME_MAX;
RefPtr<Image> image = static_cast<Image*>(mOverlayImage.get());
mozilla::gfx::IntSize size = image->GetSize();
VideoSegment segment;
segment.AppendFrame(image.forget(), delta, size);
srcStream->AppendToTrack(TRACK_VIDEO_PRIMARY, &segment);
