Hi all,

    $gst-launch playbin2 uri=file:///mnt/test.mp4

    Everything is ok, but when I write a script to call it continuity,it get the problem like this:

You need to explicitly set elements to the NULL state before

dropping the final reference, to allow them to clean up.

This problem may also be caused by a refcounting bug in the

application or some element.

Can someone tell me what wrong with it? Thanks!


By the way, the hw I use is sabrelite, and the linux BSP version I use is "L3.0.35_4.0.0".

Hi Leo,

    I use gplay to test, and I found something maybe the problem.

    When I use the below command to play a list of video continuity:

   gplay -r --video-sink=mfw_v4lsink --audio-sink=alsasink /mnt/media/*

    It get the same problem.

    Is it the bug of playbin2, and how to fix it?

    ps:

       When play a media, I need to resize the v4l output according to the w/h scale, that is what I need to assign the video-sink.

Hi Tony,

Even, I am also facing the same issue.
Did you resolve it ?

BSP Version : L3.0.35_4.1.0

Board : SabreSD based custom board.

My Script :

#bin/bash

echo -e "\033[9;0]" > /dev/tty0

while [ 1 ]

do

gplay /iwtest/SeaOfMonsters.avi

cat /sys/class/thermal/thermal_zone0/temp

done

Could you please clarify me if you didn't solve.

What is the error ?

How to resolve it ?

Thanks in Advance.

Best Regards,

J.P.Raja
