推荐答案

要加在记录视频水印，你就必须插入一些水印滤入图，确实拍摄和录制。在我的应用程序，我通过样品采集做。过滤使箱，因为它是从输入源捕获的访问每个视频帧

To add a watermark in the recorder video, you would have to insert some watermarking filter into the graph that does capture and recording. In my apps, I am doing it via sample grabber filter which enables me to access every video frame as it is captured from the input source.

虽然小心：该帧将在一些像素格式，并如果它不是RGB24你会在很多麻烦画的东西就可以了。如果可能的话，配置您的输入源RGB24，你就可以在其上描绘即使GDI和GDI +。

Beware though: the frame will be in some pixel format, and if it's not RGB24 you'll be in a lot of trouble to draw something on it. If possible, configure your input source to RGB24 and you'll be able to draw on it even with GDI or GDI+.
