Hi,

Another patch to improve compatibility!

In some circumstances you don't like to support the Full Transport Stream. I mean, you like to 'block' any "pids=all" request. Some scenarios where this would be wished for could be:

• Using a Stream Analyzer when your tuner can't provide the full TS.
• With bogus clients who perform the scaning process by requesting the entire TS.
• When you want to 'protect' your wireless clients from heavy TS (>40Mbps).
• etc.

In these circunstances this patch helps. It adds the option to replace the "pids=all" parameter with a the list of pids [0-20]. Look at the patch:

An upgrade to this enhancement may be to provide to the user the option for selecting the list of pids to replace. However, this is a second step.
Please if you agree commit this patch as well.
Thank you!
