Description
Fixes distorted/slowed audio when Twitch Enhanced Broadcasting (multitrack video) is enabled.
Motivation and Context
In our code audio output is processed per active canvas. Paired audio encoders were not inheriting the canvas/mix context from their paired video encoder, which allowed the same audio encoder to receive duplicate audio blocks when multiple canvases were active. Which is our case because we create both canvases (contexts) even in single streaming mode.
Additionally, fixed a duplicated during the merge BPM packets setup block.
Fix
When pairing audio and video encoders in
obs_output, make the audio encoder follow the paired video encoder's canvas association.How Has This Been Tested?
Manually, Windows only.
