Class AppBridgeVideoSourceBlock

Namespace

VisioForge.Core.MediaBlocks.Bridge

Assembly

VisioForge.Core.dll

Video source block using appsrc for direct buffer injection from AppBridgeVideoSinkBlock. This block receives video buffers with preserved timestamps from a linked AppBridgeVideoSinkBlock, solving timing issues with Decklink and other hardware outputs. Unlike intervideosrc-based bridges, this implementation preserves original PTS/DTS timestamps, enabling proper synchronization with hardware clocks. Use this with AppBridgeVideoSinkBlock for live sources that require precise timestamp handling.
