Add contiguousInputFrame=TRUE to your TIVidenc1 element.

Also, since this is a TI related plugin issue, you're better off cross 
posting there as well. This mailing list is more so for general 
Gstreamer issues; you're having a TI-related issue.

https://gforge.ti.com/gf/project/gstreamer_ti/forum/?action=ForumBrowse&forum_id=187

I've seen your posts here and it doesn't look like you've looked at the 
TI provided documentation for Gstreamer at all. A lot of us TI 
developers have gone through the same issues and have posted solutions 
as well. You'd be well off (as well as any other TI developer) looking 
at the forum and looking at the TI Gstreamer wiki.
