Change ATTRIBUTE_PATTERN in SessionDescriptionParser

[nibblis]

Can you change SessionDescriptionParser?

I would like to change:
ATTRIBUTE_PATTERN = Pattern.compile("([0-9A-Za-z-]+)(?::(.*))?");
to
ATTRIBUTE_PATTERN = Pattern.compile("([0-9A-Za-z-_]+)(?::(.*))?");
add _

The problem is that my camera's response contains the line a=Media_header:MEDIAINFO=494D4B48010100000400010000000000000000000000000000000000000000000000000000000000; and an exception is thrown:

Caused by: com.google.android.exoplayer2.ParserException: Malformed Attribute line: a=Media_header:MEDIAINFO=494D4B48010100000400010000000000000000000000000000000000000000000000000000000000;

Support for special characters is added in RFC4566, while we implemented RFC2327.

There will be a patch soon.
