示例1: VideoException
void updateBitmapBgr32(uint8_t* pixels, int w, int h)
{
if(currentFrame == 0){
FlogE("Video::updateBitmapBgr32() called but currentFrame is unset");
throw VideoException(VideoException::EScaling);
}
AVPixelFormat fmt = PIX_FMT_RGB32;
AVPicture pict;
int avret = avpicture_fill(&pict, pixels, fmt, w, h);
if(avret < 0){
FlogE("avpicture_fill returned " << avret);
throw VideoException(VideoException::EScaling);
}
currentFrame->CopyScaled(&pict, w, h, fmt);
}示例2: updateOverlay
