- Error strings are no longer capitalized nor end with punctuation
- Alias import
- Remove extraneous initilisation code (No need to provide zero value
for variables, because the compiler does that anyway)
We need to set up the pion/webrtc logger to write output to the
snowflake log, otherwise the warnings we are getting from the pion
library are being lost.
Note: this requires go version 1.13 and later in order to use the
`log.Writer()` function.
Modified the snowflake client to use pion/webrtc as the webrtc library.
This involved a few small changes to match function signatures as well
as several larger ones:
- OnNegotiationNeeded is no longer supported, so CreateOffer and
SetLocalDescription have been moved to a go routine called after the
other peer connection callbacks are set
- We need our own deserialize/serialize functions
- We need to use a SettingEngine in order to access the
OnICEGatheringStateChange callback
