Hi everyone,
I wanted to hack with a few video filter plugins, just for the fun of it. But what I want to do is to create more frames then what comes in.
Let's say that the source video stream has 100 frames in total, after my filter has run on the stream it will be 200 frames (easiest to start that way at least).
I have tried around a bit with the SDK to solve this, but so far without any luck. If someone has a good hint to point me in the right direction that would be great.
I guess exactly the same kind of thing needs to be done in fitlers that changes frame-rate. Like the scan-line removal filters that doubles the frame rates...
Thanks in advance...

You can do this via the prefetch hooks, as there you have complete control over the frame mapping, but the gotcha is that you still need to provide a mapping for audio and you do not have control over the audio itself from the video filter. If you are attempting to insert a new section into the video, you will have to repeat existing sections of audio as filler.
