It can only duplicate or drop frames. So you can only get "multiples": like from 30 you can get 30/2, 30/3, 30/4, 30/5, ... By selecting how many frames you drop. You can also get fx 20fps from 30 or a different value, but in this case that will only give you an "average fps". The time differences between the frames will vary: 33ms, 66ms, 33ms, 66ms, ... Instead of 50ms, 50ms, 50ms. Because of the frame dropping. <blockquote type="cite" cite="mid:mailman.37.1634040003.26064.gstreamer-devel@lists.freedesktop.org"> <pre class="moz-quote-pre" wrap=""> Regards</pre> </blockquote> <pre class="moz-signature" cols="72">-- Best regards / Med venlig hilsen “Marianna Smidth Buschle”</pre> </body> </html>
