The encoded frames are stored in buffers pulled from a buffTab. At the end of the loop, the encoded buffer's "useMask" was not being set to zero (unused), rather it was being &= with ~0x2. So, maybe something got out of sync with the flags, not sure, but setting the useMask to zero made everything peachy. Also had issues with their setting of source caps each time a new frame was encoded. Not sure why that didn't work, but removing the code proved to move things along from a deadlock. Will revisit this one.

I dont recall it immediately, but just a clue ?

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!
