There are indeed no docblobs for the both soundtouch elements. As you have figured the usage already, it would be great if you would send a patch adding the docblobs to the top of the *.cc files.

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'<br> <br> 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.<br> <br> 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?<br> <br> Thank you<br> <br> Victor<br> </div> <br> _______________________________________________ gstreamer-devel mailing list <a class="moz-txt-link-abbreviated" href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a class="moz-txt-link-freetext" href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a></div> </div> <br> _______________________________________________ gstreamer-devel mailing list <a class="moz-txt-link-abbreviated" href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a class="moz-txt-link-freetext" href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a></div> </div> <pre wrap=""> <fieldset class="mimeAttachmentHeader"></fieldset> _______________________________________________ gstreamer-devel mailing list <a class="moz-txt-link-abbreviated" href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a class="moz-txt-link-freetext" href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </pre> </blockquote> <br> </body> </html>
