We’re trying to connect to a gige camera with areadetector (using ADaravis).  We would like to access the camera images via a pv that returns a jpeg of the image rather than an uncompressed byte stream.

We’ve got the camera connected, we’ve got an NDPluginCodec setup that takes the images and apparently is producing compressed jpeg images.  We can enable acquisition and watch the MEDM screen show frames arriving and degree of compression, etc.

 Our problem is:  how do we access those images?  There doesn’t seem to be any PV that returns the jpeg.  Perhaps we’re supposed to pass the output of the codec to something else but we can’t seem to find anything that tells us how to do that.

Help would be appreciated.
