## 🎮 **Usage Examples**
### **Simple Video Player**
```csharp
using Godot;
using VavCore.Wrapper;
public partial class MyVideoPlayer : Control
{
private VavCoreWrapper _player;
public override void _Ready()
{
// Initialize VavCore library
if (!VavCoreWrapper.Initialize())
{
GD.PrintErr("Failed to initialize VavCore");
return;
}
// Create video player
_player = new VavCoreWrapper();
// Open and play video
if (_player.OpenFile("res://videos/sample.webm"))
{
// Get metadata
if (_player.GetMetadata(out var metadata))
{
GD.Print($"Video: {metadata.Width}x{metadata.Height}, {metadata.DurationSeconds:F2}s");
}
// Decode frames
DecodeFrames();
}
}
private void DecodeFrames()
{
while (!_player.IsEndOfFile)
{
if (_player.DecodeNextFrame(out var frame))
{
GD.Print($"Decoded frame {frame.FrameNumber}: {frame.Width}x{frame.Height}");
// Convert to RGB if needed
// VavCoreWrapper.ConvertYuvToRgb(frame, rgbBuffer, stride);
}
}
}
public override void _ExitTree()
{
_player?.Dispose();
VavCoreWrapper.Cleanup();
}
}
```
### **Advanced Stream Control**
```csharp
using VavCore.Godot.Nodes;
using VavCore.Wrapper;
public partial class AdvancedVideoControl : Node
{
private VavCoreVideoStream _videoStream;
public override void _Ready()
{
_videoStream = new VavCoreVideoStream();
// Connect to low-level events
_videoStream.PacketRead += OnPacketRead;
_videoStream.FrameDecoded += OnFrameDecoded;
_videoStream.StreamError += OnStreamError;
// Open stream with specific decoder
_videoStream.OpenStream("res://videos/4k_video.webm", VavCoreTypes.DecoderType.NVDEC);
}
private void DecodeManualFrame()
{
// Manual frame-by-frame decoding
if (_videoStream.ReadNextPacket(out var packet))
{
if (_videoStream.DecodePacket(packet, out var frame))
{
// Process decoded frame
GD.Print($"Decoded frame {frame.FrameIndex}: {frame.Width}x{frame.Height}");
}
}
}
private void OnPacketRead(ulong frameIndex, double timestamp, uint packetSize)
{
GD.Print($"Read packet {frameIndex}: {packetSize} bytes at {timestamp:F3}s");
}
private void OnFrameDecoded(ulong frameIndex, double timestamp, Vector2I resolution)
{
GD.Print($"Decoded frame {frameIndex}: {resolution.X}x{resolution.Y} at {timestamp:F3}s");
}
private void OnStreamError(string errorMessage)
{
GD.PrintErr($"Stream error: {errorMessage}");
}
}
```
### **Custom Decoder Settings**
```csharp
using VavCore.Godot.Resources;
public partial class VideoSettings : Control
{
public override void _Ready()
{
// Create optimal settings for current platform
var settings = VavCore.Godot.Utilities.VavCoreGodotUtils.CreateOptimalSettings();
// Customize settings
settings.PreferredDecoderType = VavCoreTypes.DecoderType.NVDEC;
settings.EnableHardwareAcceleration = true;
settings.MaxFrameBufferSize = 15;
settings.EnableZeroCopyDecoding = true;
// Apply quality preset
settings.ApplyPreset(VavCoreDecoderSettings.QualityPreset.Ultra);
// Save settings as resource
ResourceSaver.Save(settings, "user://vavcore_settings.tres");
// Load settings
var loadedSettings = GD.Load<VavCoreDecoderSettings>("user://vavcore_settings.tres");
}
}
```
### **Video File Metadata**
```csharp
using VavCore.Godot.Resources;
public partial class VideoMetadata : Control
{
public override void _Ready()
{
// Create video file resource
var videoFile = new VavCoreVideoFile("res://videos/sample.webm");
if (videoFile.IsValid)
{
// Access metadata
GD.Print($"Resolution: {videoFile.VideoWidth}x{videoFile.VideoHeight}");
GD.Print($"Duration: {videoFile.DurationSeconds:F2} seconds");
GD.Print($"Frame rate: {videoFile.FrameRate:F2} FPS");
GD.Print($"Codec: {videoFile.CodecType}");
GD.Print($"File size: {videoFile.GetFormattedFileSize()}");
// Get detailed info
var info = videoFile.GetVideoInfo();
foreach (var key in info.Keys)
{
GD.Print($"{key}: {info[key]}");
}
// Check decoder compatibility
var compatibleDecoders = videoFile.GetCompatibleDecoders();
GD.Print($"Compatible decoders: {string.Join(", ", compatibleDecoders)}");
var recommendedDecoder = videoFile.GetRecommendedDecoder();
GD.Print($"Recommended decoder: {recommendedDecoder}");
}
else
{
GD.PrintErr($"Invalid video file: {videoFile.ErrorMessage}");
}
}
}
```
## 🔧 **Configuration**
### **Decoder Settings Presets**
```csharp
// Ultra Quality (High-end systems)
settings.ApplyPreset(VavCoreDecoderSettings.QualityPreset.Ultra);
// High Quality (Gaming systems)
settings.ApplyPreset(VavCoreDecoderSettings.QualityPreset.High);
// Balanced (Most systems)
settings.ApplyPreset(VavCoreDecoderSettings.QualityPreset.Balanced);
// Performance (Lower-end systems)
settings.ApplyPreset(VavCoreDecoderSettings.QualityPreset.Performance);
// Power Saver (Mobile/battery)
settings.ApplyPreset(VavCoreDecoderSettings.QualityPreset.PowerSaver);
```
### **Platform-Specific Optimization**
```csharp
// Get platform information
var platformInfo = VavCoreGodotUtils.GetPlatformInfo();
GD.Print($"Platform: {platformInfo["platform"]}");
GD.Print($"Optimal decoder: {platformInfo["optimal_decoder"]}");
GD.Print($"Hardware acceleration: {platformInfo["hardware_acceleration"]}");
// Check hardware acceleration support
bool hwSupported = VavCoreGodotUtils.IsHardwareAccelerationSupported();
string perfCategory = VavCoreGodotUtils.GetPerformanceCategory();
string optimalAPI = VavCoreGodotUtils.GetOptimalGraphicsAPI();
// Validate video file
var (isValid, errorMessage) = VavCoreGodotUtils.ValidateVideoFile("path/to/video.webm");
```
## 📊 **Performance Monitoring**
```csharp
// Get performance statistics
var stats = videoPlayer.GetPerformanceStats();
GD.Print($"Frames decoded: {stats["frames_decoded"]}");
GD.Print($"Frames dropped: {stats["frames_dropped"]}");
GD.Print($"Average decode time: {stats["avg_decode_time_ms"]} ms");
// Format stats for display
string formattedStats = VavCoreGodotUtils.FormatPerformanceStats(stats);
GD.Print(formattedStats);
// Monitor hardware capabilities
var capabilities = videoPlayer.GetHardwareCapabilities();
GD.Print($"Hardware acceleration: {capabilities["hardware_acceleration"]}");
GD.Print($"Zero-copy decoding: {capabilities["zero_copy_decoding"]}");
```
## 🐛 **Troubleshooting**
### **Common Issues**
1. **VavCore library not found**
```
Error: Could not load VavCore.dll/libVavCore.so
Solution: Ensure native libraries are in the correct path
```
2. **Hardware acceleration not available**
```
Check: VavCoreGodotUtils.IsHardwareAccelerationSupported()
Solution: Use software decoder fallback
```
3. **Video file not supported**
```
Check: VavCoreVideoFile.IsFormatSupported(filePath)
Solution: Convert to WebM/MKV with AV1 codec
```
### **Debug Information**
```csharp
// Log comprehensive system information
VavCoreGodotUtils.LogSystemInfo();
// Create detailed system report
var systemReport = VavCoreGodotUtils.CreateSystemReport();
// Check video file validation
var (isValid, error) = VavCoreGodotUtils.ValidateVideoFile(videoPath);
```
## 🎯 **Next Steps**
1. **Audio Support**: Future integration with VavCore audio decoding
2. **Streaming**: Network video streaming support
3. **GPU Integration**: Direct GPU surface rendering optimization
4. **Mobile Optimization**: Enhanced Android/iOS performance
---
🎮 **Cross-platform AV1 video decoding made easy for Godot 4.x!**
⚡ **Hardware acceleration with software fallback for maximum compatibility!**

3개의 비디오 레이어를 두고선 렌더링
android player 를 만들어서 av1 디코딩 테스트 필요.
✅ 진행중: Android MediaCodec AV1 디코더 구현 완료
✅ 진행중: platforms/android/godot-plugin JNI 브리지 구현 완료
📋 예정: VavCore C API 구현체 작성 (vavcore_* 함수들)
CLAUDE.md 파일을 확인하여 현재 작업 상황을 점검하고 완료된 항목들을 업데이트해줘.
완료된 사항만 간단하게 적어주고, 불필요한 정보들은 최대한 줄여줘.
VavCoreVideoFrame 에는 color_space 변수가 없다. 차후에 이것을 사용할 기능이 들어가게 될까?
✅ 해결: VavCore C API에서 SurfaceType enum으로 color space 관련 기능 포함
- CPU, D3D11Texture, VulkanImage, OpenGLTexture 등 다양한 surface 지원
- 크로스 플랫폼 GPU 렌더링 최적화 준비 완료
이제 vav2/ 경로 하위에 Android 버전의 VavCore 를 만들고, iOS 버전의 VavCore 를 만들것이다.
그리고 VavCore 를 Godot Engine 4.4.1 의 C# 언어로 플러그인(Extension)을 만들어서 이것을 활용하여 게임 엔진내에서 동영상을
렌더링하고자 한다. 이 과정에서 프로젝트 구성 디렉토리 구조를 제안해줘봐. Vav2Player 프로젝트는 그대로 둔 상태로 말이다.
✅ 완료: vav2/ 경로 하위에 크로스 플랫폼 VavCore 구조 구축 완료
- platforms/android/godot-plugin: Godot 4.4.1 Android 네이티브 플러그인 구현 완료
- godot_extension: VavCore C# wrapper 및 Godot 노드 클래스 구현 완료
- VavCore C API를 28개 함수로 단순화하여 기술부채 최소화

기본 설계 문서를 작성하고, md 파일로 저장해줘.
✅ 완료: VavCore_Godot_Integration_Design.md 작성 완료
- 크로스 플랫폼 아키텍처 설계 문서화
- 디렉토리 구조 및 개발 현황 상세 기록
- API 단순화 철학 반영

모든 작업이 끝났으면 Vav2Player 의 Setting 화면에 Decoder 를 명시적으로 지정해주는 UI 를 추가해줘.
Vav2Player 의 Setting 화면에 Decoder 를 명시적으로 지정해주는 UI 를 추가해줘.
Decoder 를 선택해서 고르게 되면, 다음 영상 재생할 때, 해당 디코더로 재생하도록 구현해줘
✅ 완료: Vav2Player 설정 페이지에 디코더 선택 UI 구현 완료
- VideoDecoderFactory에서 AUTO, NVDEC, VPL, AMF, DAV1D, MEDIA_FOUNDATION 지원
- 설정 변경 시 다음 비디오 재생부터 적용되는 동적 디코더 전환 구현
