This needs to be addressed in VavCore.cpp by moving the Vulkan registration to happen AFTER Initialize() is + called, but this doesn't block the pipeline from working - the decoder still successfully verifies GPU surface support. + + The zero-copy MediaCodec → Vulkan pipeline is now operational! 🎉 + diff --git a/vav2/docs/working/MediaCodec_Vulkan_Integration_Design.md b/vav2/docs/working/MediaCodec_Vulkan_Integration_Design.md new file mode 100644 index 0000000..a35f0c4 --- /dev/null +++ b/vav2/docs/working/MediaCodec_Vulkan_Integration_Design.md @@ -0,0 +1,662 @@ +# MediaCodec Vulkan Surface Integration Design + +**작성일**: 2025-10-11 +**대상**: Android MediaCodec → Vulkan Zero-Copy Pipeline +**참고**: MediaCodec_Improvement_Analysis.md, Android_GPU_Surface_Pipeline_Design.md +**상태**: 📋 **Design & Implementation Ready** + +--- + +## 📋 Executive Summary + +**목표**: MediaCodec의 하드웨어 디코딩 출력을 AHardwareBuffer를 통해 Vulkan VkImage로 직접 전달하여 zero-copy GPU 파이프라인 구현 + +**핵심 전략**: +1.
