Re: [Gumstix-users] Overo Fire & DSP for jpeg compression

[Chris W. <whi...@gm...>]

Have you looked at using gstreamer's appsink?  That would hand the
jpeg frames to your own app-- or I think you can even do a callback
with fakesink to get the frames.

I use this technique to use gstreamer to capture and process jpeg
frames before handing them to mjpg-streamer.

Of course, there is nothing wrong with the way you want to do it
either.  In my case, I wanted to use other gstreamer elements to
overlay text and tee the video off to an avi file.  All of that is
pretty easy with gstreamer.

I need to get the compressed jpeg image back to the gumstix prior to sending so that I can embed meta data into it.  I was really hoping to use dsplink, but can't get any of the sample to run.  I'm pretty sure I'm just not mapping the memory properly.  Any other thoughts?
