[gst-devel] backward seeking

[Andoni Morales]

Hi!
If you set the start time at 0, a backward seeking will try to seek to
negatives values. It will place your stream at 0 mseconds and then it will
try to go backward witch is imposible as it's the end of the stream. Try
changing your start time to curpos*GST_MSECOND. It will seek to a new
position with positive values and your stream will be played backward to the
0 position.
