  -----------
  Fix codec handling functions when faulty streams are defined.

Bogus test on the return code of stream_process() (using bitwise OR for -1, 0 and 1 values :O ), leads to a generic failure to find any codec in any stream if there is an invalid stream in the SDP.
For example, if a video stream is defined but with no codecs, stream_process() will return -1 for it (as it is a bogus stream). While iterating through all the stream (including the valid audio stream), the -1 ret code will discard any 1 future ret code due the bogus bitwise OR.
