           Summary: payloaders: VP8 and Opus payloader should probably
                    suppport Google Chrome encoding-names
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal

While implement WebRTC client that speak with Google Chrome, I found that
encoding-name for draft payload RFC won't match the one in GStreamer.

For VP8, Google uses "VP8", where GStreamer uses "VP8-DRAFT-IETF-01". For opus,
Google uses "opus" where GStreamer uses "X-GST-OPUS-DRAFT-SPITTKA-00". In order
to inter-operate better, I suggest we could add these two "well known" names to
our payloader / depayloaders. This would avoid having to implement codec
specific hacks in when parsing codecs in SDP.

Let's me know if this is acceptable, if so I'll provide patches. This is likely
to help inter-operability on RTSP side too, as the parser there does not have
any of such hacks.
