[gst-devel] Properly seeking in a track with gst-python

[Jason Gerard DeRose]

Adam,

I'm guessing you are trying to seek to 10 seconds into your track.
gstreamer0.8 (and as far as I know, 0.10 also) deals in nano seconds
(10^-9).  So you will need to multiply your seconds by gst.SECOND

nano_sec = sec * gst.SECOND

event = gst.event_new_seek(gst.FORMAT_TIME |
        				gst.SEEK_METHOD_SET |
				gst.SEEK_FLAG_FLUSH, nano_sec)

10 nano seconds is so close to the start of your track that you can't
tell the difference (well, and maybe so close that the bits gstreamer
spits out are the same as when starting from the beginning).

Happy hacking,
Jason
