The following patch adds support for trick play streams from Kasenna
The date in the patch refer to the SVN checkout of vlc-trunk it is
PATCH 1:- kasenna_trickplay-20051021.diff
The first patch adds the trickplay support. It's based off a patch that
Dermot (dermot at lincor.com) submitted at the start of the year. The rc
interface fastforward and rewind commands are used to set the rate
variable to what the user inputs. e.g. "fastforward 12" or "rewind 12"
to play y the x12 FF/RW streams from the Kasenna. If those values are
not passed and just the commands, then the rate is set to a flag value
of INPUT_RATE_MAX/MIN. The setting of rate triggers a callback in
src/input/input.c as before, however, in there, I make a call to the
demux2Control to use SET_RATE. If this fails, it falls back to normal
behaviour of setting the rate of play from the buffer.
In the modules/demux/livedotcom.cpp there's a new SET_RATE section to
the Control function.
This pauses the stream, then restarts the stream with the scale value
set to what was passed in with the fastforward command. If the values
that where passed in match INPUT_RATE_MAX/MIN then a default scale
factor of 30 is used. The Kasenna will choose the closest matching
scale. By default it's 12x
