Class AppBridgeVideoSinkBlock

Namespace

VisioForge.Core.MediaBlocks.Bridge

Assembly

VisioForge.Core.dll

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