Hello Sebastian,
Thanks for your answer. Can you tell me how to achieve a seek on a particilar part of a pipeline ? Do I have to "isolate" the part before webrtcbin, and then how ? Are there different options ? I am a little bit lost ! ++ Jack Le 05/02/2019 à 10:52, Sebastian Dröge a écrit : > On Fri, 2019-02-01 at 16:59 +0100, Jack wrote: >> Hello ! >> >> I am able to seek with seek_simple() in a simple pipeline like : >> >> 'filesrc location=17seconds48000D.wav ! wavparse ! audioconvert ! >> audioresample ! autoaudiosink' >> >> But how I can seek in this pipeline using webrtcbin ? : >> >> 'webrtcbin name=sendrecv bundle-policy=max-bundle filesrc >> location=17seconds48000D.wav ! wavparse ! opusenc ! rtpopuspay ! >> application/x-rtp,media=audio,encoding-name=OPUS,payload=96,clock- >> rate=48000 >> ! sendrecv. >> >> Using directly seek_simple() seems to not work. > > You need to seek only on the part of the pipeline before the webrtcbin > and ensure that payloader and everything following get a contiguous > segment of data. > > > _______________________________________________ > gstreamer-devel mailing list > [hidden email] > https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel > _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Trying to be more precise on the word "isolate" I used in my previous
answer : do I need to use appsrc/appsink or proxysrc/proxysink to seek on the pipeline connected to a webrtcbin pipeline, or I am on the wrong way ? ++ Jack Le 08/02/2019 à 17:41, Jack a écrit : > Hello Sebastian, > > Thanks for your answer. > Can you tell me how to achieve a seek on a particilar part of a pipeline > ?

Come back with this thread...
I tried the following to seek in a pipeline involving webrtcbin pad. Sebastian recommended to seek only on the part before webrtcbin, but i can't make it work, i certainly missed something or misunderstood something. My soundfile on the hard drive last 18 min : - create a pipeline 'main' : filesrc ! ... ! tee - set state of this pipeline to PLAYING - seek on this pipeline with seek_simple(Gst.Format.TIME, Gst.SeekFlags.FLUSH | Gst.SeekFlags.KEY_UNIT, 120 * Gst.SECOND) - gst_pipe_to_add = Gst.parse_bin_from_description('queue ! webrtcbin name=sendrecv bundle-policy=max-bundle', True) - add gst_pipe_to_add to the pipeline 'main' - link between tee and gst_pipe_to_add - set state of gst_pipe_to_add to PLAYING I can get the sound stream but it start from the beginning instead of 2 min after the beginning. Any clue or more ?
