[opus] OPUS encoded file required

[Ralph Giles]

The Opus codec relies on external framing to determine packet lengths.
There's no such thing as encoded opus data stored without a container.

If you're familiar with RTP, this example code may be helpful. It
extracts the sequence of delimited packets from a `.opus` file format
and sends them over rtp.

Hope that's some help. Thank you for your interest in Opus.

Sincerely,
Ralph
