don't know, if there are various solutions, but you can convert the
framebuffer into a pix again using [pix_snap]. either you can grab both
together, the video and the text, so that you display the text already
upon the video, or you could grab the text separately (in a free area of
the gemwin) and use [pix_mix] to merge the text-pix and the video
afterwards. the former is possibly simpler to implement, but since you
are applying a pix as texture in order to display it in opengl and then
converting it back to a pix again, this might introduce interpolation
artefacts. 
however, if you have alltogether in one pix, you can simply record it
using [pix_record].
