This diff simply adds support for calling and using the new
frame scrubbing or quick seek mode in the core. Please see
the
"CR: Add support for Frame Scrubbing (QuickSeek with
frame display)"
cr email on other mailing lists for a full discussion of the
work.
To use QuickSeek from splay simply pause the core and use
the
'>' key to quickseek() forward and the '<' key to
quick seek
back. It acts more like slow motion forward and backwards
because
the amount you seek is fixed. I guess we could be more
creative
in the way we simulate a real slider on a GUI player, but
this
works for now. Perhaps in the future we could increase the
seek
distance the longer they held down the keys....
for HEAD and 150Cay.

Looks good. I think I had previously added some code
in clientapps/simpleplayer/main.cpp when I was testing
this feature a while back. I think I had splay
respond on the command-line to "qs" for quick
seek
(funny, I named it the same thing back then). We should
probably remove that code now.
