RTP depay for L8-encoded audio

[Matt Staples]

Hi,

I am trying to add support for playing raw audio with 'L8' encoding
from an RTP stream.  I couldn't find an appropriate rtpdepay element
for that type though.  Is that a missing feature, or am I just looking
for it by the wrong name?

Thanks,
-Matt

It's indeed not implemented yet. I assume you mean L8 according to
  https://tools.ietf.org/html/rfc3551#section-4.5.10
?

Yes, that's correct.

I'm guessing that I could implement that pretty easily though by
copying, say, rtpl16depay and making the applicable changes.  If I do
end up doing that, I'll create a feature-request in bugzilla and add
that as a patch.

Thanks,

Yes, it should be just a copy of the L16 depayloader, but simpler.

If you can control both receiver and sender, using PCMA/U (alaw/mulaw)
could also make sense btw.
