I am trying to extract an image frame from a video taken from iPhone

  • 0

I am trying to extract an image frame from a video taken from iPhone camera using ffmpeg. But it usually throws me a EXEC_BAD_ACCESS and the stacktrace is showing in another method calls that is never called (I know my code didn’t call it)

I am using the ffmpeg built from the instruction of the iFrameExtractor website. If anybody do it successfully, please help me or if possible, send me some codes. I don’t know why it crashes, although it works well on the simulator (which I manually import a video into the library). My guess is that ffmpeg cannot decode the iPhone video camera correctly.

I already tried to use all 3 sets of library files like arvm6, arvm7 and i386 but doesn’t work. My iPhone is 3gs. My iphone sdk is 3.1.3

    I think it is my fault in calling the VideoFrameExtractor. The example code doesn’t work well. I have to change from videoExtractor.currentImage to [videoExtractor currentImage]
