It is set to 10s and 200 buffers respectively by default. Set these to 0 to disable. regards, Nicolas _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Likely because you didn't disable the "max-size-time" and/or "max-size- buffers" property. It is set to 10s and 200 buffers respectively by default. Set these to 0 to disable. Queue2 default configuration is different, as it targets a different use case. regards, Nicolas > > Frederic > > > > -----Message d'origine----- > De : gstreamer-devel [mailto:[hidden email] > p.org] De la part de Nicolas Dufresne > Envoyé : mardi 10 octobre 2017 15:47 > À : Discussion of the development of and with GStreamer > Objet : Re: Queue Overrun > > Le mardi 10 octobre 2017 à 08:42 +0000, Duchassin Frédéric a écrit : > > Hello, > > > > I use this pipeline on Imx6 : > > > > gst-launch-1.0 udpsrc address=239.0.0.1 port=1234 ! queue max- > > size_bytes=20000000 min-threshold-bytes=100 ! tsdemux name=d > > program- > > Please notice your typo here, It's "max-size-bytes" with a - not a _. > > > number=275 ! multiqueue name=q use-buffering=1 d. ! q. q. ! queue > > ! > > decodebin ! queue ! imxg2dvideosink q. ! queue ! decodebin ! queue > > ! > > audioconvert ! volume volume=10 ! alsasink > > > > > > And i get queue OVERRUN signal on queue before decodebin. > > I try to search why this queue has overflow by reading level and I > > get > > this : > > > > OVER_RUN : bufferdecodebinvideo : Max buffer size : 100000000 > > OVER_RUN : bufferdecodebinvideo : Number of bytes in buffer : > > 1159086 > > > > ??? > > > > Why I get overrun whereas the max-size of queue is not reached ? > > > > BR. > > > > Frederic > > > > _______________________________________________ > > 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 gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

It is normal behaviour to overrun when max-size-time, or max-size- buffers is reached even if that's much smaller then max-size-bytes. Set them all to 0 EXCEPT the metric you want to support, this will fix your issues. regards, Nicolas _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
