Simulating a live stream from mutiple files - HELP

[Shishir Pokharel]

Hi all,

I am trying to simulate a live stream from files. I followed following post but it's not working for me at all. I am using gstreamer 1.4.4

http://gstreamer-devel.966125.n4.nabble.com/change-quot-location-quot-of-filesrc-element-without-breaking-tcpserversink-connection-td4661248.html

My pipeline looks like :
Fileserc-> decodebin ->queue -> videoconvert -> videoscale -> navseek->queue->autovideosink

I have pad probe on queue sink pad and stuck on following state;


1)      For the first segment send; it changes the start time to 0 and end time to -1;

2)      Send flush start to filesrc on EOS received on queue sink pad on separate ptherad.

3)      Queue sink pad receives flush start and DROPS the data but decodebin goes to lock state.

Any directions for the issue is appreciated;

Here is trace log:
