Hi All,
This is probably right under my nose...if I just knew what to search for. But, let's get it in one place. Given a filesrc (or a stream, I suppose) containing some sort of recorded video recorded at hi-def, big size, etc., (NOTE: I'm starting with mjpeg for now.) How do I change to a different format, say, mjpeg to mpeg? How do I alter the compression ratio? How do I reduce the image size? How do I lower the image quality (lower the resolution)? Thanks, Wes |
Wes,
All of this can be accomplised by gstreamer. So write a gstreamer application to do that. Best Kapil On Wed, Jun 9, 2010 at 8:42 PM, Wes Miller <[hidden email]> wrote:

Stefan,
Thanks for the kind answers. Even as I wrote these questions I knew I was having a dead-brain day.
