OBS-Studio 18.0.0 with FTL.0.9.0

OBS-Studio 18.0.0 with FTL Support and Browser Source

Change log:

• Updated to OBS Studio 18.0.0
• Updated UI Framework to QT 5.8 (this should fix plugin compatibility issues)
• Updated OSB Browser to 1.29 (latest)
• OBS now defaults to zerolatency if it has not been set by the user.
• Updated FTL to 0.9.0
  • Fixed a few audio and video sync issues when streaming with FTL

Lowest Latency Settings

Some encoders have more delay than others, for ~200ms of delay use the following settings:

• Beam FTL Service
• Ingest: Auto
• Output Mode: Advanced
• Rate control: CBR
• bitrate: max allowed is 10,000 kbps
• Key Frame interval: 3
• CPU Usage: this is more related to how hard the encoder tries to do a good job; faster values typically means the encoder spends less time resulting in lower quality for the same bitrate. if you have a very good CPU you can pick a slower settings but pay attention to how much CPU OBS is consuming. Some of the very slow settings will introduce more delay to improve the encoding quality (recommended setting: faster)
• profile: high
• tune: zero latency

Notes:

• This is a BETA, use at your own risk. Beam support will be limited
• local Recording is NOT supported when using FTL. It will cause random behavior that will impact your FTL stream
• Use the Beam FTL Service under Stream tab
• Use Auto as your ingest (it will find the optimal ingest taking into account, distance from you to the ingest, ingest load, ingest bandwidth, ingest memory utilization, and a few other factors)
• Audio sample rate MUST be 48Khz (requires a restart if it was using 44.1khz)
