<div dir="ltr">I followed this sugestions but I didnt work >Also just send a SEEK event to the source pad that is connected to the >input-selector, otherwise you will seek on all of the input-selector >sources. the scenario is: <div> </div><div>v4l2src ----------> </div>filesrcbin ------> input-selector--->pipeline----tee ---->autovideosink ------> audiomixer ----->rtmpsink alsasrc --------> <div>all video stream are connected to a input-selector, and audio to audiomixer. </div><div> </div>alsa and v4l2src have the do-timestamp properties set true. and sinks the sync property true. input-selector has the default properties, sync all income streams, the same for audiomixer. <div>for seeking I do the follow: </div><div>1. add a probe in a src pad of a filesrc bin (the ghos pad connected to a input-selector) the probe is the type downstream </div><div>2. in the callback function, if there a eos event then perform the seek of type segment </div>the seek is implemented as follow: if (GST_EVENT_TYPE (GST_PAD_PROBE_INFO_DATA (info)) == GST_EVENT_EOS){ GstSeekFlags seek_flags; gboolean ret; gint64 duration; gst_element_query_duration(v->decoder, GST_FORMAT_TIME, &duration); seek_flags = GST_SEEK_FLAG_SEGMENT; gint64 start = 0; GstEvent *event = gst_event_new_seek(1.0, GST_FORMAT_TIME, seek_flags, GST_SEEK_TYPE_SET, start, GST_SEEK_TYPE_SET, duration); gst_debug_set_threshold_from_string ("*:6", TRUE); ret = gst_pad_send_event (v->videosrc, event); gst_debug_set_threshold_from_string ("*:0", TRUE); "videosrc" is a src pad connected to a input-selector. with GST_DEBUG using the functions I can see how the event is sended to all elements in the bin until qtdemux , see the logs bellow <a href="http://pastebin.com/WzMRv31g" target="_top" rel="nofollow">http://pastebin.com/WzMRv31g</a> and in the logs: <div class="">0:00:53.868032558 21438 0x1fc0c00 DEBUG qtdemux qtdemux.c:1580:gst_qtdemux_do_seek:<qtdemux1> configuring seek</div><div class="">0:00:53.868058679 21438 0x1fc0c00 DEBUG default gstsegment.c:317:gst_segment_do_seek: updated segment.base: 42887979166</div><div class="">0:00:53.868082708 21438 0x1fc0c00 INFO default gstsegment.c:372:gst_segment_do_seek: segment updated: time segment start=0:00:00.000000000, offset=0:00:00.000000000, stop=0:00:42.902000000, rate=1,000000, applied_rate=1,000000, flags=0x08, time=0:00:00.000000000, base=0:00:42.887979166, position 0:00:00.000000000, duration 0:00:42.902000000</div><div class="">0:00:53.868125630 21438 0x1fc0c00 DEBUG qtdemux qtdemux.c:1473:gst_qtdemux_perform_seek:<qtdemux1> seeking to 0:00:00.000000000 </div><div class="">and then in the bus there is a segment-done message, but on the autovideosink if the sink pad which is connected videosrc ghost pad, is active, the image on the screen is frezze. so I dont now what happen here. </div><div class="">I thing the seek was performed but input-selector or audiomixer has another time-stamp, and in this case the file is very short(~1:30 min) so, the time-stamp of the pipeline is </div><div class="">higher.
