# AMD AMF AV1 Decoder Design Document
|
||||
|
||||
## Overview
|
||||
This document describes the design and implementation of the AMD AMF (Advanced Media Framework) AV1 decoder integration within the VavCore library. The AMF decoder provides hardware-accelerated AV1 decoding on AMD GPUs.
|
||||
|
||||
## Architecture
|
||||
|
||||
### Class Hierarchy
|
||||
```
|
||||
IVideoDecoder (interface)
|
||||
└── AMFAV1Decoder (implementation)
|
||||
```
|
||||
|
||||
### Key Components
|
||||
- **AMFAV1Decoder**: Main decoder class implementing IVideoDecoder interface
|
||||
- **VideoDecoderFactory**: Factory class extended to support AMF decoder creation
|
||||
- **AMF SDK Integration**: Direct integration with AMD AMF SDK headers and libraries
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### File Structure
|
||||
```
|
||||
VavCore/src/Decoder/
|
||||
├── AMFAV1Decoder.h # AMF decoder header
|
||||
├── AMFAV1Decoder.cpp # AMF decoder implementation
|
||||
├── VideoDecoderFactory.h # Updated factory header
|
||||
└── VideoDecoderFactory.cpp # Updated factory implementation
|
||||
```
|
||||
|
||||
### Dependencies
|
||||
- **Headers**: `D:\Project\video-av1\include\amf\`

|
||||
|
||||
## Core Functionality
|
||||
|
||||
### Initialization Process
|
||||
1. **AMF Library Loading**: Load external AMF component via `g_AMFFactory.LoadExternalComponent()`
|
||||
2. **Context Creation**: Create AMF context using `CreateContext()`
|
||||
3. **Graphics API Initialization**: Initialize DirectX 11 (fallback to DirectX 9)
|
||||
4. **Decoder Component Creation**: Create AV1 decoder using `AMFVideoDecoderHW_AV1`
|
||||
5. **Property Configuration**: Set decoder properties (surface copy, reorder mode)
|
||||
|
||||
### Decoding Pipeline
|
||||
```
|
||||
AV1 Packet → AMFBuffer → AMF Decoder → AMFSurface → VideoFrame
|
||||
```
|
||||
|
||||
1. **Input Processing**: Create AMFBuffer and copy packet data
|
||||
2. **Submission**: Submit input buffer to decoder via `SubmitInput()`
|
||||
3. **Output Query**: Poll for decoded frames using `QueryOutput()`
|
||||
4. **Surface Conversion**: Convert AMFSurface to VideoFrame with proper format handling
|
||||
|
||||
### Surface Format Support
|
||||
- **NV12**: Primary format with interleaved UV plane conversion
|
||||
- **YUV420P**: Planar YUV 4:2:0 format
|
||||
- **YUV422P**: Planar YUV 4:2:2 format (if supported)
|
||||
- **YUV444P**: Planar YUV 4:4:4 format (if supported)
|
||||
|
||||
## Error Handling
|
||||
|
||||
### AMF Error Codes
|
||||
Comprehensive mapping of AMF result codes to human-readable messages:
|
||||
- `AMF_OK`: Success
|
||||
- `AMF_FAIL`: General failure
|
||||
- `AMF_NOT_SUPPORTED`: Feature not supported
|
||||
- `AMF_NO_DEVICE`: No compatible AMD device
|
||||
- `AMF_INPUT_FULL`: Input queue full (retry required)
|
||||
- `AMF_REPEAT`: Output not ready (normal for some frames)
|
||||
|
||||
### Error Recovery
|
||||
- **Initialization Failure**: Graceful fallback to other decoders
|
||||
- **Runtime Errors**: Frame-level error handling with statistics tracking
|
||||
- **GPU Context Loss**: Automatic cleanup and re-initialization capability
|
||||
|
||||
## Integration with VideoDecoderFactory
|
||||
|
||||
### Decoder Priority Order (AUTO mode)
|
||||
1. **ADAPTIVE_NVDEC**: NVIDIA adaptive decoder (highest priority)
|
||||
2. **AMF**: AMD AMF decoder (new addition)
|
||||
3. **ADAPTIVE_DAV1D**: dav1d adaptive decoder
|
||||
4. **NVDEC**: NVIDIA hardware decoder
|
||||
5. **DAV1D**: dav1d software decoder
|
||||
6. **MEDIA_FOUNDATION**: Windows Media Foundation (fallback)
|
||||
|
||||
### Factory Enhancements
|
||||
- Added `DecoderType::AMF` enumeration
|
||||
- Implemented `CheckAMFAvailability()` method
|
||||
- Updated decoder creation logic with AMF support
|
||||
- Added AMF decoder to supported decoders list
|
||||
|
||||
## Performance Characteristics

AMF_RESULT result = amf::g_AMFFactory.LoadExternalComponent(temp_factory, L"AMFFactory");
|
||||
return (result == AMF_OK && temp_factory);
|
||||
}
|
||||
```
|

1. **개방-폐쇄 원칙 위반**: 새 디코더 추가시 팩토리 클래스 수정 필요
|
||||
2. **헤더 의존성 충돌**: 서로 다른 SDK 헤더들이 같은 심볼 정의로 충돌
|
||||
3. **컴파일 시간 증가**: 모든 디코더 헤더가 팩토리에 포함됨
|
||||
4. **빌드 환경 의존성**: 특정 SDK가 없으면 전체 빌드 실패
|
||||
|
||||
## 🎯 **등록 기반 팩토리 패턴 솔루션**
|
||||
|
||||
### **핵심 아이디어**
|
||||
- **등록자(Registrar)**: 각 디코더가 자신을 팩토리에 등록
|
||||
- **팩토리(Factory)**: 등록된 생성자 함수들을 통해 객체 생성
|
||||
- **자동 등록**: 디코더 구현 파일에서 자동으로 등록 수행
|
||||
- **헤더 분리**: 팩토리는 구체 디코더 헤더를 포함하지 않음
|
||||
|
||||
## 🏗️ **단순화된 아키텍처 설계**
|
||||
|
||||
### **핵심 원칙**
|
||||
- **복잡한 DecoderRegistry 제거** → VideoDecoderFactory 내부 배열 사용
|
||||
- **템플릿 클래스 제거** → 간단한 함수 포인터 등록
|
||||
- **매크로 최소화** → 가독성 있는 등록 함수 사용
|
||||
|
||||
### **1. 단순화된 등록 시스템**

```
|
||||
|
||||
## 🔄 **단순화된 사용 예시**
|
||||
|
||||
### **기본 사용법**
|
||||
```cpp
|
||||
// 1. 자동 선택 (가장 적합한 디코더, 우선순위 기반)
|
||||
auto decoder = VideoDecoderFactory::CreateDecoder(VideoCodecType::AV1, DecoderType::AUTO);
|
||||
|
||||
// 2. NVIDIA NVDEC 하드웨어 디코더 강제 사용
|
||||
auto nvdecDecoder = VideoDecoderFactory::CreateDecoder(VideoCodecType::AV1, DecoderType::NVDEC);
|
||||
|
||||
// 3. Intel VPL 하드웨어 디코더 강제 사용
|
||||
auto vplDecoder = VideoDecoderFactory::CreateDecoder(VideoCodecType::AV1, DecoderType::VPL);
|
||||
|
||||
// 4. AMD AMF 하드웨어 디코더 강제 사용
|
||||
auto amfDecoder = VideoDecoderFactory::CreateDecoder(VideoCodecType::AV1, DecoderType::AMF);
|
||||
|
||||
// 5. dav1d 소프트웨어 디코더 강제 사용
|
||||
auto dav1dDecoder = VideoDecoderFactory::CreateDecoder(VideoCodecType::AV1, DecoderType::DAV1D);
|
||||
|
||||
// 6. Media Foundation 디코더 강제 사용
|
||||
auto mfDecoder = VideoDecoderFactory::CreateDecoder(VideoCodecType::AV1, DecoderType::MEDIA_FOUNDATION);
|
||||
|
||||
// 7. 사용 가능한 디코더 목록 조회
|
||||
auto available = VideoDecoderFactory::GetAvailableDecoders(VideoCodecType::AV1);
|
||||
for (const auto& name : available) {
|
||||
std::cout << "Available AV1 decoder: " << name << std::endl;
|
||||
}
|
||||
```
|
||||
|
||||
### **WebM 파일 처리 예시**
|
||||
```cpp
|
||||
// WebM 코덱 ID에서 자동 디코더 생성
|
||||
std::string codecId = "V_AV01"; // WebM의 AV1 코덱 ID
|
||||
VideoCodecType codecType = VideoDecoderFactory::DetectCodecTypeFromId(codecId);
|
||||
auto decoder = VideoDecoderFactory::CreateDecoder(codecType, DecoderType::AUTO);
|
||||
|
||||
if (decoder) {
|
||||
std::cout << "Created decoder for: " << codecId << std::endl;
|
||||
} else {
|
||||
std::cout << "No suitable decoder found for: " << codecId << std::endl;
|
||||
}
|
||||
```
|
||||
|
||||
## 🚀 **단순화된 설계의 장점**
|
||||
|
||||
### **1. 개방-폐쇄 원칙 준수**
|
||||
- ✅ **개방**: 새로운 디코더 추가 용이 (각자의 cpp 파일에서 등록)
|
||||
- ✅ **폐쇄**: VideoDecoderFactory 헤더/구현 수정 불필요
|
||||
|
||||
### **2. 헤더 의존성 완전 분리**
|
||||
- ✅ **충돌 제거**: VideoDecoderFactory가 구체 디코더 헤더를 포함하지 않음
|
||||
- ✅ **빌드 시간 단축**: 불필요한 헤더 컴파일 제거
|
||||
- ✅ **선택적 빌드**: 특정 SDK 없어도 나머지 디코더는 정상 빌드
|
||||
|
||||
### **3. 구현 단순성**
|
||||
- ✅ **복잡한 DecoderRegistry 제거**: 간단한 std::vector 사용
|
||||
- ✅ **템플릿/매크로 최소화**: 가독성 높은 함수 기반 등록
|
||||
- ✅ **디버깅 용이**: 복잡한 싱글톤/템플릿 없이 직관적인 구조
|
||||
|
||||
### **4. 성능 최적화**
|
||||
- ✅ **우선순위 기반 선택**: 시스템 환경에 따른 최적 디코더 자동 선택
|
||||
- ✅ **가용성 기반 필터링**: 사용 불가능한 디코더 자동 제외
|
||||
- ✅ **정적 초기화 활용**: 런타임 오버헤드 최소화
|
||||
|
||||
### **5. 유지보수성 향상**
|
||||
- ✅ **관심사 분리**: 각 디코더가 자신의 등록 로직만 관리
|
||||
- ✅ **코드 가독성**: 복잡한 등록 시스템 없이 명확한 구조
|
||||
- ✅ **확장성**: 새로운 코덱 타입 추가 시에도 동일 패턴 적용 가능
|
||||
|
||||
## 📋 **단순화된 구현 계획**
|
||||
|
||||
### **Phase 1: 단순화된 VideoDecoderFactory 구현**
|
||||
1. 기존 복잡한 VideoDecoderFactory.h/.cpp 교체
|
||||
2. `DecoderRegistration` 구조체 기반 등록 시스템 구현
|
||||
3. 정적 std::vector를 사용한 디코더 저장소 구현
|
||||
|
||||
### **Phase 2: 디코더별 등록 변환**
|
||||
1. `AV1Decoder.cpp`에 단순화된 등록 로직 추가
|
||||
2. `NVDECAV1Decoder.cpp`에 등록 로직 추가
|
||||
3. `VPLAV1Decoder.cpp`에 등록 로직 추가
|
||||
4. `AMFAV1Decoder.cpp`에 등록 로직 추가 (AMF SDK 사용 가능 시)
|
||||
|
||||
### **Phase 3: 빌드 및 테스트**
|
||||
1. VavCore 라이브러리 빌드 테스트
|
||||
2. 헤더 의존성 제거 확인
|
||||
3. 디코더 자동 등록 및 우선순위 동작 검증
|
||||
|
||||
### **Phase 4: 기존 코드와 통합**
|
||||
1. WebMFileReader에서 새로운 팩토리 사용 확인
|
||||
2. VideoPlayerControl에서 디코더 생성 로직 업데이트
|
||||
3. 전체 애플리케이션 통합 테스트
|
||||
|
||||
## 🎯 **단순화된 설계의 결론**
|
||||
|
||||
**함수 포인터 기반 등록 패턴**을 통해:
|
||||
- ✅ **PIMPL 패턴의 복잡성 없이** 헤더 의존성 문제 완전 해결
|
||||
- ✅ **개방-폐쇄 원칙 준수**로 확장 가능한 아키텍처 구현
|
||||
- ✅ **복잡한 싱글톤/템플릿 제거**로 코드 가독성 향상
|
||||
- ✅ **정적 초기화 활용**으로 성능 최적화
|
||||
- ✅ **직관적인 등록 시스템**으로 디버깅 및 유지보수 용이
|
||||
|
||||
**기존 복잡한 등록 시스템 대비 장점:**
|
||||
- DecoderRegistry 싱글톤 제거 → 간단한 정적 배열 사용
|
||||
- DecoderRegistrar 템플릿 제거 → 명확한 함수 기반 등록
|
||||
- 복잡한 매크로 제거 → 가독성 높은 구조체 초기화 방식
|
||||
- 범용적인 문자열 기반 API 제거 → 타입 안전한 enum 기반 접근법
|
||||
|
||||
이 단순화된 설계는 Vav2Player의 디코더 생태계를 더욱 **유연하고 유지보수하기 쉽게** 만들어, 미래의 새로운 디코더 추가나 SDK 변경에도 robust하게 대응할 수 있습니다.

이 때문에, VideoDecoderFactory 클래스가 새로운 구현체(implementor)가 추가될 때마다 헤더파일에서의 빌드 충돌 문제가 발생하고 있고,

이를 해결하기 위해 pimp 패턴으로 수정되어야 하는 것은 바람직하지 않습니다.

libvpl 을 빌드하여, Debug 는 postfix 에 -debug 를 붙여서, dll 라이브러리를 만들어줘.
|
||||
헤더파일은 D:\Project\video-av1\include\libvpl 경로에.
|
||||
라이브러리 파일은 D:\Project\video-av1\lib\libvpl 경로에 각각 빌드해줘.
|
||||
Debug, Release 모두 빌드해줘.
|
||||
그리고 빌드 스크립트로 D:\Project\video-av1\build_libvpl.bat 를 작성해줘.
|

AMF 빌드하여, Debug 는 postfix 에 -debug 를 붙여서, dll 라이브러리를 만들어줘.
|
||||
헤더파일은 D:\Project\video-av1\include\amf 경로에.
|
||||
라이브러리 파일은 D:\Project\video-av1\lib\amf 경로에 각각 빌드해줘.
|
||||
Debug, Release 모두 빌드해줘.
|
||||
그리고 빌드 스크립트로 D:\Project\video-av1\build_amf.bat 를 작성해줘.
|
||||
마찬가지로 build 디렉토리를 만들고 거기서 적절한 빌드 환경 파일을 만들어야 할꺼야.
|
||||
참고로, AMF 는 빌드 환경 코드가 같이 배포되지 않았다.
|
||||
build_amf.bat 에서 이를 감안하고 스크립트를 작성해야할 것이다.
