Class AppBridgeAudioSinkBlock

Namespace

VisioForge.Core.MediaBlocks.Bridge

Assembly

VisioForge.Core.dll

Audio sink block using appsink for direct buffer transfer between pipelines. This block captures audio buffers and passes them directly to a linked AppBridgeAudioSourceBlock with preserved timestamps, solving timing issues with Decklink and other hardware outputs. Unlike interaudiosink-based bridges, this implementation gives full control over buffer timing and avoids clock synchronization issues. Use this with AppBridgeAudioSourceBlock for live sources that require precise timestamp handling.
