[gst-devel] How to Set Buffer Size Within Plugin

[Michael Joachimiak]

I think you need to specify source caps according to sink caps. When you get
video/smth,width=640,height=480,.... on sink you can set source to the same
but width=1280,height=960. And obviously create the correct buffer size to
push on the src.
Is that what you want?
If you need more details give details yourself, otherwise we could end up
discussing apples and oranges.
