how to save selected video frames into file

[wei_j_]

I want to use the F200 to check every current frame  to detect mobile object in video and once a mobile object was detected, I should save the following frames(about 300),then detect mobile object again.

But I only found a function, SetFilename and it just record the vidio from beginning to end.

Is there any way just save the frames or one frame  what I need into file?

What format do you want to save the frames to?

If you want to use the .rssdk format, after setting the filename, you can use 
pSenseManager.captureManager.SetPause(true);
To pause recording (or rather, not start yet), then use it again set to false when you want to start again.

If you want to save the frames individually, or in a format readable by other things (like an .avi), you can export each frame to a bitmap then do what you want with those.

Thanks for your answering

if I save the frames to .rssdk format, how can I read the video I have saved?

Actually I want to save the frames in the second way.can you tell me more details about it ?

To play back an .rssdk video, you use SetFilename but give it the file you've already saved and set the second argument to false (true == record, false == playback).

Which environment/language are you using? I can only really help on your second question if you're using C# .net.

I use C++.But you can still tell me how to do with C# .I  could have a try in the future.

Words can‘t express my gratitude.

This thread will tell you how to get bitmaps (or the C++ equivalent) from the camera stream. Then I'm sure Google will point you towards an API which will help you convert your group of bitmaps into a video file. Good luck!
