Bring Your Animations to H264/HEVC Video

In this article, we go through four examples. In the first example, we render a red video, in the second example, we load a JPEG image with GDI+ and render once, that is when frame_cnt is zero, in the third example, we display first image and slowly alphablend with the second image until it appears, and in our last example, we show the two pre-rendered text images appearing from the middle of the video.
