gstreamer playbin2 problem

Tony_Luo — Fri, 21 Mar 2014 05:58:38 GMT

Hi all,

I use gstreamer playbin2 to play video file(mp4) like this:

$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:

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".

What does the script look like?

Do you see problem launching this script?

while true; do gst-lauch playbin2 uri=file://$media; done

Hi Leo,

I use the script like yours, whould you please try it on and after several hour gone, you can get the same problem, I think.

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 ]

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
