( Bulk transfers a 4096 bytes).<br> <br> The problem is that the create function from GstPushSrc seems not to be called often/fast enough to get all the data from the USB device.<br> <br> Did I forget to set some rate , or how to solve that?<br> <br> Thx Roland<br> <br> <br> <br> <br> <br> _______________________________________________<br> gstreamer-devel mailing list<br> <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a><br> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a><br> </blockquote></div><br><br clear="all"><br>-- <br>Sincerely,<br>Bobby<br> </div> _______________________________________________<br>gstreamer-devel mailing list<br><a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a><br>http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel<br></div><br></div></body></html>
