How to pause FFmpeg from C++ code?

Question

I'm writing a VisualC++ program which have code invoke ffmpeg.exe to convert video file. I wonder is it possible to pause/resume ffmpeg converting thread from C++ code?

LR.

Answer 1

All you need to do is suspend and resume the ffmpeg child process itself.

The main problem is: there is no SuspendProcess API function. And there is no documented or safe way of doing this.

The only simple way of doing this is via SuspendThread/ResumeThread.

See this article on codeproject about how to do it.

Answer 2

There are no ways to controls the conversion using ffmpeg.

However, if you switch you mencoder, you will be able to do it.
