Where could you to change the output video size? -----Original Message----- From: Michael Joachimiak [<A HREF="mailto:mjoachimiak@gmail.com">mailto:mjoachimiak@gmail.com</A>] Sent: Fri 10/15/2010 3:34 PM To: Discussion of the development of GStreamer Subject: Re: [gst-devel] How to Set Buffer Size Within Plugin 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. 2010/10/15 Michael Smith <msmith@xiph.org> > Well, that's just up to what your plugin outputs.
