hi,
wim, in
http://webcvs.freedesktop.org/gstreamer/gst-plugins-good/gst/level/gstlevel.c?r1=1.74&r2=1.75you changed "endtime" to be returned as stream time instead of running time.
Comment was that this is what the application wants. Either is miss something or
don't agree here. I update level meters on the screen with the details from
GstLevel. For a long time I just ignored the endtime and triggered resraws
immediately. For a pipeline like src ! level ! fx1 ! level ! fx2 ! level ! sink
it had the consequense the meters where not in sync. Now I tried to sync them:
GstClockTime endtime;
if(gst_structure_get_clock_time (structure, "endtime", &endtime)) {
gconstpointer *params=g_new(gconstpointer,2);
GstClockID clock_id;
GstClockTime waittime;
GstClockTime basetime =
gst_element_get_base_time(GST_ELEMENT(GST_MESSAGE_SRC(message)));
/* this only work for the first loop :/
* root cause is that level/spectrum send endtime as stream_time and not
* as running_time
*/
waittime=basetime+endtime;
GST_DEBUG("target %"GST_TIME_FORMAT" %"GST_TIME_FORMAT,
GST_TIME_ARGS(endtime),GST_TIME_ARGS(waittime));
params[0]=(gpointer)self;
params[1]=(gpointer)gst_message_copy(message);
clock_id=gst_clock_new_single_shot_id(self->priv->clock,waittime);
gst_clock_id_wait_async
(clock_id,on_delayed_song_level_change,(gpointer)params);
gst_clock_id_unref(clock_id);
}
Problem here is that I want to sync with the pipeline clock. Without having
access to accum filed in segment I can see how to convert the stream_time to
running_time. A segment-query unfortunately does not return the accum field :/
Any ideas? Should we change level back to return running_time or is there a way
I can convert from the application.
And bt.w spectrum still uses gst_segment_to_running_time(), so we shoudl atleast
make it consistent.
