Instead of going for EOS , filesrc element waits. i believe this is the reason filesrc not changing to READY or NULL state. I will check your solution with appsrc element , which i will read from the fio and push to the appsrc element.</div><div><div class="h5"><div class="gmail_extra"> <div class="gmail_quote">On Tue, Mar 6, 2018 at 6:57 PM, Bernhard Graaf <<a href="mailto:bernhard.graaf@gmx.de" target="_blank">bernhard.graaf@gmx.de</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div lang="DE" link="blue" vlink="blue"> <div class="m_-8725796476907962853m_-6238810299267647367Section1"> Quit simple: Generate named pipe.

In my implementation , the /tmp/test is also a fifo. the filesrc element read from this fifo. But i am not able to send EOS even to pipeline or the filesrc element (call isn't returned ). I have tried ulinking and deleting this fifo, also tried with fdsrc instead of filesrc. All result in same behaviour. Would you tell me if i am doing anything wrong? the pipeline is stopping correctly when running in foreground. Only cause issues when run from other programs using system() command or making this as an application. </div> </div> <div> <div> On Tue, Mar 6, 2018 at 4:51 PM, bernhard.graaf <<a href="mailto:bernhard.graaf@gmx.de" target="_blank">bernhard.graaf@gmx.de</a>> wrote: <div> <div> I handle this with a named pipe </div> <div> </div> <div> </div> <div> </div> <div id="m_-8725796476907962853m_-6238810299267647367m_-5738193980912035446composer_signature"> <div> Von meinem Samsung Galaxy Smartphone gesendet. </div> </div> <div> </div> <div> <div> -------- Ursprüngliche Nachricht -------- </div> <div> Von: Anjo John <<a href="mailto:anjo.john@vvdntech.in" target="_blank">anjo.john@vvdntech.in</a>> </div> <div> Datum: 06.03.18 08:13 (GMT+01:00) </div> <div> An: Discussion of the development of and with GStreamer <<a href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">gstreamer-devel@lists.freedesktop.org</a>> </div> <div> Betreff: element send EOS event not returning </div> <div> </div> </div> <div> <div> <div> Hi All, <div> i have a Gstreamer application to read H264 data from a fifo and decode+display.
