||||
```json
|
||||
{
|
||||
"type": "error",
|
||||
"message": "导出失败: 文件不存在",
|

}
|

```
|
||||
|
||||
## 前端集成示例
|
||||
|
||||
### JavaScript/TypeScript
|
||||
```typescript
|
||||
async function exportVideo(exportRequest: ExportRequest) {
|
||||
const response = await fetch('/api/export/stream', {
|
||||
method: 'POST',
|
||||
headers: {
|
||||
'Content-Type': 'application/json',
|
||||
'Accept': 'text/event-stream'
|
||||
},
|
||||
body: JSON.stringify(exportRequest)
|
||||
});
|
||||
|
||||
const reader = response.body?.getReader();
|
||||
const decoder = new TextDecoder();
|
||||
|
||||
while (true) {
|
||||
const { done, value } = await reader!.read();
|
||||
if (done) break;
|
||||
|
||||
const chunk = decoder.decode(value);
|
||||
const lines = chunk.split('\n');
|
||||
|
||||
for (const line of lines) {
|
||||
if (line.startsWith('data: ')) {
|
||||
const data = JSON.parse(line.slice(6));
|
||||
handleProgressEvent(data);
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
function handleProgressEvent(event: any) {
|
||||
switch (event.type) {
|
||||
case 'start':
|
||||
console.log('导出开始');
|
||||
break;
|
||||
case 'progress':
|
||||
console.log(`进度: ${event.progress * 100}% - ${event.message}`);
|
||||
break;
|
||||
case 'complete':
|
||||
console.log('导出完成:', event.download_url);
|
||||
break;
|
||||
case 'error':
|
||||
console.error('导出失败:', event.message);
|
||||
break;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 重要注意事项
|
||||
|
||||
### 1. 视频源处理优先级
|
||||
1. **本地文件路径** - 直接使用
|
||||
2. **HTTP/HTTPS URL** - 自动下载
|
||||
3. **Blob URL** - 需要提供 `videoFiles` 中的 base64 数据
|
||||
|
||||
### 2. 高质量流复制模式
|
||||
- 系统默认启用流复制模式，保持原始视频质量
|
||||
- 处理速度提升 10-20 倍
|
||||
- 零质量损失
|
||||
|
||||
### 3. 音频兼容性
|
||||
- 自动检测混合音频情况
|
||||
- 智能处理有音频/无音频片段的兼容性
|
||||
|
||||
### 4. 错误处理
|
||||
- 无效视频源会被自动跳过
|
||||
- 详细的错误信息通过 SSE 实时推送
|
||||
|
||||
### 5. 云存储集成
|
||||
- 支持七牛云自动上传
|
||||
- 上传失败时提供本地下载链接
|
||||
|
||||
## 验证接口
|
||||
|
||||
在正式导出前，建议先调用验证接口：
|
||||
|
||||
```http
|
||||
POST /api/export/validate
|
||||
Content-Type: application/json
|
||||
|
||||
{
|
||||
"ir": { /* 同导出接口的ir参数 */ },
|
||||
"options": { /* 同导出接口的options参数 */ }
|
||||
}
|
||||
```
|
||||
|
||||
验证接口会检查：
|
||||
- IR 数据完整性
|
||||
- 视频分辨率、帧率、时长
|
||||
- 导出选项有效性
|
||||
- 返回详细的验证错误信息
