<div dir="ltr">Hi people, I'm trying to add inputs to videomixer from filesrc dynamically. I have a videotestsrc as background (with is-live=TRUE). When I want to add a new input I create a bin with filesrc, decodebin, videorate and videoconvert. Then I request a pad on the mixer and I link it to the bin. It works OK but not as I need. Every time I add a new input to the mixer the video file start from the current running time and not from the beginning as I expected. I've tried to replace the first SEGMENT event at the decodebin src pad with a pad probe and replace it with a new event where start=0 and end=-1. But it seems to not make any difference. Also I've tried to replace the segment with a new one where the segment.base=<running_time_from_the_pipeline>, but the pipeline freezes. The log shows that the new videomixer:sink receives the segment event and then both mixer's sinks sent a qos event. I've tried two ways for replace the segment event, the first one was to drop the first event(returning GST_PAD_PROBE_DROP) and send a new one from the app. (Seeing the logs the videomixer receives the two segment events). The other way was to replace de event on the GstPadProbeInfo on the probe. I'm using gst 1.2.2 and a C application. The example's code is here: <a href="http://pastebin.com/KGyjky1R">http://pastebin.com/KGyjky1R</a> Every suggestion is welcomed Thanks!</div>
