If you want to encode them, add a x264enc (for <br> example) before matroskamux. <br> <br> <br> > Even when i did simple pipeline <br> > videotestsrc ! avimux ! filesink location=c:\gstreamer\test.avi <br> > i was not able to see information about video, navigate in video. <br> > And it was opened not in all players. <br> <br> I suspect not all players will be able to handle raw video in AVI. <br> Also, if you use gst-launch-1.0 (or your own app) you will need to make <br> sure that you shut down the pipeline 'cleanly', so that the muxer has <br> an opportunity to finalise the file properly (write indices, fix up the <br> header, etc.). In gst-launch-1.0 you do that by passing the -e command <br> line option, or using videotestsrc num-buffers=100 or such. In your <br> application you would have to send an EOS event on the pipeline with <br> gst_element_send_event(pipeline, gst_event_new_eos()) and then wait for <br> an EOS message on the bus before shutting down the pipeline with <br> gst_element_set_state(). <br> <br> Cheers <br> -Tim <br> <br> -- <br> Tim Müller, Centricular Ltd - <a href="http://www.centricular.com" target="_top" rel="nofollow" link="external"> http://www.centricular.com</a><br> <br> Join us at the GStreamer Conference! <br> 10-11 October 2016 in Berlin, <br> Germany <br> <a href="http://gstreamer.freedesktop.org/conference/" target="_top" rel="nofollow" link="external">http://gstreamer.freedesktop.org/conference/</a><br> <br> <br> _______________________________________________ <br> gstreamer-devel mailing list <br> <a href="/user/SendEmail.jtp?type=node&node=4679636&i=0" target="_top" rel="nofollow" link="external">[hidden email]</a> <br> <a href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_top" rel="nofollow" link="external">https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a><br> <br> <br> <hr noshade="noshade" size="1" color="#cccccc"> <div style="color:#444; font: 12px tahoma,geneva,helvetica,arial,sans-serif;"> <div style="font-weight:bold">If you reply to this email, your message will be added to the discussion below:</div> <a href="http://gstreamer-devel.966125.n4.nabble.com/Video-processing-record-play-real-time-from-camera-with-metadata-tp4679305p4679636.html" target="_top" rel="nofollow" link="external">http://gstreamer-devel.966125.n4.nabble.com/Video-processing-record-play-real-time-from-camera-with-metadata-tp4679305p4679636.html</a> </div> <div style="color:#666; font: 11px tahoma,geneva,helvetica,arial,sans-serif;margin-top:.4em;line-height:1.5em"> To unsubscribe from Video processing(record\play) real time from camera with metadata, <a href="" target="_top" rel="nofollow" link="external"> click here</a>.<br> <a href="http://gstreamer-devel.966125.n4.nabble.com/template/NamlServlet.jtp?macro=macro_viewer&id=instant_html%21nabble%3Aemail.naml&base=nabble.naml.namespaces.BasicNamespace-nabble.view.web.template.NabbleNamespace-nabble.view.web.template.NodeNamespace&breadcrumbs=notify_subscribers%21nabble%3Aemail.naml-instant_emails%21nabble%3Aemail.naml-send_instant_email%21nabble%3Aemail.naml" rel="nofollow" style="font:9px serif" target="_top" link="external">NAML</a> </div> </div> <div class="small"><br/><img src="http://gstreamer-devel.966125.n4.nabble.com/images/icon_attachment.gif" > <strong>wmp error.png</strong> (175K) <a href="http://gstreamer-devel.966125.n4.nabble.com/attachment/4679647/0/wmp%20error.png" target="_top" rel="nofollow" link="external">Download Attachment</a></div> <br/><hr align="left" width="300" /> View this message in context: <a href="http://gstreamer-devel.966125.n4.nabble.com/Video-processing-record-play-real-time-from-camera-with-metadata-tp4679305p4679647.html">Re: Video processing(record\play) real time from camera with metadata</a><br/> Sent from the <a href="http://gstreamer-devel.966125.n4.nabble.com/">GStreamer-devel mailing list archive</a> at Nabble.com.<br/>
