Description Gwenole Beauchesne 2013-12-02 17:14:01 UTC 
This is the MPEG-2 encoding counterpart for bug #719691.

Expected changes:
- Default profile to which encoded streams need to conform: "Simple Profile"
- "max-bframes" then need to be set to zero
- If "max-bframes" > 0, then profile is inferred to be "Main Profile".

    encoder: mpeg2: derive profile and level from active coding tools.
    
    Automatically derive the minimum profile and level to be used for
    encoding, based on the activated coding tools. Improve lookup for
    the best suitable level with the new MPEG-2 helper functions.
    
    Also change the default profile to "simple" so that to ensure maximum
    compatibility when the stream is decoded.
