How to capture a still image while previewing live video?

[Paul Stuart]

Hello Kapil,
 Right you are!

But...still doesn't work. I'm strongly suspecting TI's TIImgenc1 
implementation at this point. Looking at the source code for it, it 
looks like it *should* work, as they've implemented a circular buffer 
system to buffer incoming and outgoing buffers. When I turn logging on, 
I see the following snippet:

 GST_ERROR_SYSTEM 
gstelement.c:1761:gst_element_message_full:<tiimgenc10> posting message: 
Failed to queue input buffer into circular buffer

0:06:58.383303446  2220    0xfabc0 INFO        GST_ERROR_SYSTEM 
gstelement.c:1784:gst_element_message_full:<tiimgenc10> posted error 
message: Failed to queue input buffer into
circular buffer


So...digging deeper into TIImgenc1

Thanks!
Paul
