How to open file\live stream with FFMPEG edit each frame with openCV and save that as encoded with FFMPEGfile\live stream?

推荐答案

这很简单。

我建议你从简单的ffmpeg解码示例开始。这样你得到一个结构，它是一个FFMPEG图像。你必须将其转换为opencv映像结构（IplImage）。然后可以应用任何opencv操作。然后你可以看看FFMPEG编码示例，你有你的整个处理链：）

I suggest you begin with the simple ffmpeg decoding example. With that you get a struct which is an FFMPEG image. You have to convert it to an opencv image struct (IplImage). Then you can apply any opencv operation. Then you can look at FFMPEG encoding example and you have your whole processing chain :)

关键是将FFMPEG图像结构转换为opencv图像结构。在阅读文档（代码？）后，它很简单。

The point is to convert FFMPEG image struct to opencv image struct. It is quite simple after you have read the documentation (the code ?).
