[gst-devel] Jitter and pause in video playing using gstreamer ...

[Wierd O]

Hi all ,

I am using gstreamer to stream video from a file source in iMX27 freescale app processor. I have used the gst-launch command and i get the video output. But the video has jitter and sometimes pause for some time. I dont understand the problem since there is no error message. Here is the code for the output...
