Basically, by using gst_util_uint64_scale_int() in some places, the timestamp can be off by almost a nanosecond. In our pipeline we are sensitive to any error in the timestamp, and because of this (small) problem we can't use audiotestsrc to test it. Fortunately, the fix is very easy. In audiotestsrc the timestamp (in "next_time") is computed always from next_sample, so it can be solved by changing gst_util_uint64_scale_int() to gst_util_uint64_scale_int_round() (note the extra "_round") everywhere. Patch attached. Please let me know if this is ok, or if I should report a bug in some other way, etc. </blockquote><div> You should file a bug against gst-plugins-base: <a href="https://bugzilla.gnome.org/buglist.cgi?quicksearch=component%3Agst-plugins-base+product%3A">https://bugzilla.gnome.org/buglist.cgi?quicksearch=component%3Agst-plugins-base+product%3A</a>"GStreamer"+ </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Thanks, Jordi -- Jordi Burguet-Castell <<a href="mailto:jordi@gravity.phys.uwm.edu">jordi@gravity.phys.uwm.edu</a>> UWM Physics Dept. 464 1900 E.
