七牛短视频SDK使用

功能：从相册选取视频(不支持录制)，添加滤镜，上传七牛服务器

Xcode Version 11.2

SDK Version

• PLShortVideoKit (2.2.0)

1.相册选择视频

TZImagePickerController (3.2.4)

相册选择视频 得到 PHAsset *asset

2.预览 + 编辑

// 编辑工具类 短视频SDK中的类
@property (strong, nonatomic) PLShortVideoEditor *shortVideoEditor;
// 所有滤镜 短视频Demo中的获取滤镜管理类
@property (strong, nonatomic) PLSFilterGroup *filterGroup;
// 输出配置，必传参数
@property (nonatomic, strong) NSMutableDictionary *outputSettings;
@property (nonatomic, strong) NSMutableDictionary *movieSettings;

/// PHAsset 转 AVAsset  

// 核心方法
- (PHImageRequestID)requestAVAssetForVideo:(PHAsset *)asset options:(nullable PHVideoRequestOptions *)options resultHandler:(void (^)(AVAsset *__nullable asset, AVAudioMix *__nullable audioMix, NSDictionary *__nullable info))resultHandler API_AVAILABLE(macos(10.15));
// 依赖
#import <Photos/Photos.h>

// 项目代码
- (void)test {
    
    __weak typeof(self) wself = self;
    PHVideoRequestOptions *option = [[PHVideoRequestOptions alloc] init];
    option.version = PHVideoRequestOptionsVersionOriginal;
    option.deliveryMode = PHVideoRequestOptionsDeliveryModeAutomatic;
    option.networkAccessAllowed = YES;
    [[PHImageManager defaultManager] requestAVAssetForVideo:self.videoAsset options:option resultHandler:^(AVAsset * _Nullable asset, AVAudioMix * _Nullable audioMix, NSDictionary * _Nullable info) {
        dispatch_async(dispatch_get_main_queue(), ^{
            __strong typeof(self) self = wself;
            if (asset) {
                self.asset = asset;  // 存储asset,导出是需要
                self.shortVideoEditor = [[PLShortVideoEditor alloc] initWithAsset:asset videoSize:CGSizeZero];
                self.shortVideoEditor.loopEnabled = YES;
                self.shortVideoEditor.previewView.frame = self.view.bounds;
                [self.view insertSubview:self.shortVideoEditor.previewView atIndex:0];
                [self.shortVideoEditor startEditing]; // 开始编辑
                if (self.videoAsset.pixelHeight > self.videoAsset.pixelWidth) {
                    self.shortVideoEditor.fillMode = PLSVideoFillModePreserveAspectRatioAndFill;
                }

                // 总的导出参数字典对象
                self.outputSettings = [[NSMutableDictionary alloc] init];
                // 原视频参数字典对象
                self.movieSettings = [[NSMutableDictionary alloc] init];
                self.movieSettings[PLSAssetKey] = asset;
                self.movieSettings[PLSVolumeKey] = [NSNumber numberWithFloat:1.0];
                self.movieSettings[PLSStartTimeKey] = [NSNumber numberWithFloat:0.f];
                self.movieSettings[PLSDurationKey] = [NSNumber numberWithFloat:CMTimeGetSeconds(asset.duration)];
                self.outputSettings[PLSMovieSettingsKey] = self.movieSettings;
            }
        });
    }];
}
    
// 获取所有滤镜数据
    self.filterGroup = [[PLSFilterGroup alloc] initWithImage:nil];

// 添加滤镜
    self.filterGroup.filterIndex = indexPath.row; // 设置你选中的对应下标
    [self.shortVideoEditor addFilter:self.filterGroup.colorImagePath];

// 存储选中的滤镜，导出时需要
    self.colorImagePath = self.filterGroup.colorImagePath;

3.导出

// 导出成功后会回调一个 本地路径 url
- (void)export {
       
    __weak typeof(self) wself = self;
    PLSAVAssetExportSession *exportSession = [[PLSAVAssetExportSession alloc] initWithAsset:self.asset];
    // exportSession.outputFileType = PLSFileTypeMPEG4;
    exportSession.audioChannel = 2;
    exportSession.delegate = self;
    exportSession.audioBitrate = PLSAudioBitRate_128Kbps;
    exportSession.outputVideoFrameRate = MIN(60, self.asset.pls_normalFrameRate);
    exportSession.outputVideoSize = self.asset.pls_videoSize;
    [exportSession addFilter:self.colorImagePath]; // 你存储的滤镜
    exportSession.outputSettings = self.outputSettings; // 输出设置 必须设置
    
    [exportSession setCompletionBlock:^(NSURL *url) {
        
        dispatch_async(dispatch_get_main_queue(), ^{
            NSLog(@"Asset Export Completed");
           // 这里应该成功了，必须回到主线程来操作
        });
    }];
    
    [exportSession setFailureBlock:^(NSError * _Nullable error) {
        dispatch_async(dispatch_get_main_queue(), ^{
            // 失败也要在主线程处理
            NSLog(@"error - %@", error);
        });
    }];
    
    [exportSession exportAsynchronously];
}

4.上传

// token 为校验字符串 一般通过自己后台接口获取
- (void)shortVideoUploadVideo:(NSString *)token { // 短视频上传功能
    
    __weak typeof(self) wself = self;
    PLSUploaderConfiguration *config = [PLSUploaderConfiguration defaultWithToken:token];
    PLShortVideoUploader *uploader = [PLShortVideoUploader sharedUploader:config];
    [uploader uploadVideoFile:self.url.absoluteString];
    uploader.delegate = wself;
}

// 进度回调
- (void)shortVideoUploader:(PLShortVideoUploader * _Nonnull)uploader uploadKey:(NSString * _Nullable)uploadKey uploadPercent:(float)uploadPercent {
    
    __weak typeof(self) wself = self;
    dispatch_async(dispatch_get_main_queue(), ^{
        

    });
}

// 结束回调
- (void)shortVideoUploader:(PLShortVideoUploader * _Nonnull)uploader completeInfo:(PLSUploaderResponseInfo * _Nonnull)info uploadKey:(NSString * _Nonnull)uploadKey resp:(NSDictionary * _Nullable)resp {
    
    __weak typeof(self) wself = self;
    if (info.statusCode == 200) { // 成功
        
        
    } else {
        
    }
    NSLog(@"resp - %@", resp);
}
