AVAssetWriterInputPixelBufferAdaptor and CMTime

Question

I\'m writing some frames to video with AVAssetWriterInputPixelBufferAdaptor, and the behavior w.r.t. time isn\'t what I\'d expect.

If I write just one frame

Answer 1

Have you tried using this as your first call

CMTime t = CMTimeMake(0, 600);
[videoWriter startSessionAtSourceTime:t];
[adaptor appendPixelBuffer:pxBuffer withPresentationTime:t];
