For example, you say that playbin has 3 threads. Why? Is the playbin plugin written that way? So the number of threads is not decided by the framework but rather by the plugin? > The number of threads depend on the type of element used. All source elements that runs in push mode host a thread. All demuxer that pulls from sources will run a thread, all queues will introduce a thread. Additionally, external libraries may also add a threads for parallel processing, along with live mixers. The number of thread will entirely depend on the pipeline the playbin need to construct,and the depends on what is going to be played. Often, playing from local files require as low as 3-4 threads.

I heard it needs very high number of threads. For a simple playback pipeline with .mp4 with video only decode, how many threads does it roughly require? in general, appreciate your expert insight into thread heaviness of gstreamer. > >> _______________________________________________ > >> gstreamer-devel mailing list > >> <a href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">gstreamer-devel@lists.freedesktop.org</a> > >> <a href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> > > > > > > _______________________________________________ > > gstreamer-devel mailing list > > <a href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">gstreamer-devel@lists.freedesktop.org</a> > > <a href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> > > _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">gstreamer-devel@lists.freedesktop.org</a> <a href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" rel="noreferrer" target="_blank">https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div>
