[gst-devel] JPEG truncation

Hi,

I have constructed a plugin based on videotestsrc to display images from 
a Baumer camera. (Source here: http://www.grok.org.za/gst/)

My problem is that the plugin does not work properly if it can only get 
one frame at a time. The result is that if I create a jpeg using the 
command below, there is some corruption right at the bottom of the JPEG.

gst-launch-0.10 baumercamsrc ! ffmpegcolorspace ! jpegenc quality=100 ! 
filesink location=/tmp/bar.jpg

Even if I simulate data from the camera, I get the problem, so it's the 
plugin that's at fault. It requests exactly the right buffer size each 
time, so it's not like it's actually getting too little data.

It just seems that videotestsrc 'expects' continuous data. How would I 
change that?

Many thanks,
Thomas
