'Scaletempo' and it "rate" property

[Victor henri]

Hello again

On the other hand, when I compile the demo and run it, I almost always get the error messages :

     GStreamer-CRITICAL **: gst_event_new_new_segment_full: assertion `start <= stop' failed

     GStreamer-CRITICAL **: gst_pad_push_event: assertion `event != NULL' failed

This doesn't happen if I disable Scaletempo (through the checkbox)...

Hello to all

Is there please a simple example oh how to use the 'scaletempo' element? I'm aware thata there is documentation at the 'bad-plugins' directory, but this is an example in four files and seems very complicated, when I just want to know how it works basically; the trick seems to be at the "rate" property that cannot be changed directly with 'g_object_set'

I have made a simple 'equivalent' of scaletempo by combining 1) the change of speed in 'g_seek_event' and 2) the pitch element that changes in a proportional opposite way; it works.

But I understand that the "overlap", "search" and "stride" are very interesting and allow to compensante for the 'loss of quality' due essentially to the slow down of the reading. My app implements those quite simply and the demo seems very confuse to me. Is there a simple 'skeleton' or basic demo about this?

Thank you

Victor
