[gst-devel] Jitter and pause in video playing using gstreamer and no full screen ...

[Wierd O]

Here is the pipeline ...



gst-launch
filesrc -v location=/video/test.mp4 ! mfw_mp4demuxer name=demux
demux. ! mfw_vpudecoder codec-type=std_mpeg4 ! mfw_v4lsink demux. &

In addition to that, the video that i am playing is 320x240 and I want to play it full screen on 800x600. I used "disp-width=800 disp-height=600". But I couldnt get the full screen output. 

Regards,

W.

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...
