[gst-devel] backward seeking

[Ash]

Has any developer out there gotten backward seek (negative rate) to work with GST_FORMAT_TIME?

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.

The seek returns true but just hangs. Are there any other messages I can see as to what is really happening in the pipeline?> From: thaytan at noraisin.net> To: gstreamer-devel at lists.sourceforge.net> Date: Fri, 25 Jul 2008 00:08:46 +0100> Subject: Re: [gst-devel] backward seeking
