Program selection

[GoogleCodeExporter]

What steps will reproduce the problem?
Canot select a spécific program id.

What is the expected output? What do you see instead?
Implement a QVideoDecoder method :selectProgram(int programId)
which set the videoStream on programId stream_index.

What version of the product are you using? On what operating system?
version: 23 09 2011
os: win7

Please provide any additional information below.
