Video getting Freezed

[Sumanth V]

Hi All,
 
         I have written an application using dvbsrc plugin to view the incoming TV channels. When i change the channels it takes 3 to 4 seconds to switch between the channels. But i want the channel change to happen instantly. The method i am using to change the channle is
* First i set the whole pipeline to READY.
* Change the properties of the dvbsrc and mpegtsplugin, i.e set the properties of pids and es-pid to that of a new channel.
* Set the pipeline back to PLAYING.

This is working fine.
In my application i have created 2 bin's,  Audio bin and Video bin, which i link to the audio pad and video pad emitted by the mpegtsdemux.

I am able to change the channels instantly, but  video freeze's after showing the first frame of the new channel. The method i am using for this
* Set the properties of the dvbsrc and mpegtsplugin, i.e set the properties of pids and es-pid to that of a new channel.
* When mpegtsdemux emitts a new video pad for the next channel, i set the Video bin to READY state and unlink the previously linked pad of the video bin.
* Link the video bin to the newly emitted pad and set the Video bin to PLAYING state.
* Same thing i do for Audio bin also.
* It changes the channel instantly but get freezed after the showing first frame.

Why is the video getting freezed?? Where am i going wrong in my second method?


Thanks,
