What format are your input images? Do you have a sample?

Hi Davis. Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. Especially with links to your own website, we tend to flag this as spam. Please rather post the actual answer here.

comment GOP Extraction using FFMPEG
But when you extract all frames, you automatically get all frames of all GOPs? What is a "set" for you? Or do you want to name them according to the GOP they belong to (like gop001_frame01.bmp to gop200_frame05.bmp)? Or do you want to say "Export all frames of GOP 5"? Please edit and clarify your question. Show us exactly what you want as output. (Note that you have to write @slhck so that I get a notification.)

comment ffmpeg only makes movie of first picture
It's not ambiguous. The default input framerate is 25 for the image2 format. The default output framerate is the input framerate. Hence, 25 is used if not specified otherwise. Also, your example code is wrong—when you set framerate or r to 1/25 that means you have one frame every 25 seconds. -r 1/6 would be 1 image every 6 seconds. The value should be in Hz, e.g. 25. Either way, setting the framerate is not necessary and unlikely to be the cause of the issue. If you can point me to an ambiguous statement though, I'd be happy to fix it.

Please show the command-line output, otherwise we cannot diagnose what goes wrong.

comment ffmpeg only makes movie of first picture
It does not need an output frame rate. It will assume 25 by default.

That's not a standard shell feature. Were you using a custom prompt? What does your .bash_profile contain?

@sunk818 How so? This question is perfectly on topic here and I don't see how migrating it to another site would change the way it can be answered. Please read this carefully: meta.superuser.com/a/2968/48078

comment GOP Extraction using FFMPEG
I don't understand this question. Do you want one image per GOP? (If so, how should it look like?) Or just one image per frame? If it's one image per frame, why can't you just do ffmpeg -i input.mp4 out-%04d.jpg or similar?

comment How to make Handbrake preserve capture time / creation time?
Then your ffmpeg is not compiled with FAAC support. Try -c:a aac -strict experimental instead.

You need to explain what's not working with your command or where your specific problem is. Please show the real command that is run (not the Java code) and the full uncut command line output, too.

It's not clear what problem you are trying to solve. Please rather ask about that.
