I tried already to change the location already in different ways and dis read the documentation concerning dynamic pipelines At this moment I simplified the pipeline to : filesrc | decodebin| autovideosink, but still I seems to do something wrong. What I already tried is : <ul style="margin-top:0cm" type="disc"> <li style="margin-left:0cm">In blocking probe on file source I changed location with/without filesrc state changes(GST_STATE_NULL and sync with parent ) and pipeline changes ( GST_STATE_READY and GST_STATE_PLAY)</li><li style="margin-left:0cm">With 2 probes and send eos as explained in dynamic pipeline documentation , and this with creating new filesrc and/or decodebin.</li><li style="margin-left:0cm">With posting a message and change file location when message received to avoid deadlocks</li></ul> I really have no idea what I’m doing wrong or if it is even possible. I would appreciate if anyone can point me in the right direction or explains me the sequence of actions to take Cheers , marc </div> </div> </blockquote></div> </blockquote></div>
