bug fix: fix encoder input port configuration issues

1. Number of P frames being INT_MAX - 1 is misleading few components.
avoid this value
2. enumerate level: The level information is obtained from
enumerateProfileandLevel. Now the component supports up to this level
or 1 step below this level is unclear. This is causing few problems in
the configuration of input port.
3. Disable few error checks for index types that are not universally
supported
