[Asterisk-code-review] app echo: forward and generate VIDUPDATE frames (asterisk[13])

[Jacek Konieczny]

Hello Richard Mudgett, Anonymous Coward #1000019,

I'd like you to reexamine a change.  Please visit

to look at the new patch set (#3).

Change subject: app_echo: forward and generate VIDUPDATE frames
......................................................................

app_echo: forward and generate VIDUPDATE frames

When using app_echo via WebRTC with VP8 video the video would appear
only after a few minutes, because there would be nothing to request
a full reference frame.

This fixes the problem in both ways:
- echos any VIDUPDATE frames received on the channel
- sends one such frame when first video frame is to be forwarded

This makes the echo work with Firefox and Chrome WebRTC implementation.
