Due to reports that the bandwidth test is randomly causing community
strikes on Youtube (likely due to bad automatic detection), the
bandwidth test will be disabled for Youtube until the Youtube API is
implemented.
(This commit also modifies UI)
Instead of pinging Twitch every time the program starts up, only pings
for new servers when the ingests are actually being used, and when the
UI uses the auto-configuration dialog.
If ingests have not been cached when using the "Auto" server, it will
wait for 3 seconds max to query the Twitch ingest API. If it takes
longer than 3 seconds or fails, it will defer to SF. If ingests were
already cached, then it will use the existing cache immediately.
When custom server is used, it would still use the "common" RTMP service
to cap its bitrate. So if Twitch was selected and you changed over to
custom RTMP server, it would still cap to Twitch's bitrate limits even
though you're not using Twitch anymore.
Changes the default autoconfig test bitrate to 10000kb/s, which will
then be capped by the user's service selection (so it'll still only use
6000 on Twitch for example, but will allow 10000 on Youtube and others).
The auto-configuration wizard is designed to allow first-time or
novice/uneducated users or to set up video and encoding settings in a
very quick and easy way. It'll automatically perform a bandwidth test,
and/or test the user's video settings to determine the most ideal
settings for streaming and recording (assuming a 1-pc setup).
