Thanks for the suggestion.
I have set all the parameters as per sample tutorial which successfully
decode the mpeg 2 video.
Still that parameters could not help me in my application.
Add on I had also tried to open decoder as per sample application by giving
input file but result was same.
My video resolution is 720x576.
Is there any problem with this resolution.
Because my code is working with 704x576 resolution video.
So I have doubt on resolution.

Yours is, I suppose, more of a question for the libav-user group,
but...if I were
you I would try and get it to "work" with ffmpeg on the command line,
then check/see which values it passes through for the pixel format,
