#warning 修改 原为 assetVideoTrack 后改为videoTrack 发现可以解决 error code=-11841
AVMutableVideoCompositionLayerInstruction *layerInstruction = [AVMutableVideoCompositionLayerInstruction videoCompositionLayerInstructionWithAssetTrack:videoTrack];

改过之后没出现过错误了吗

因为我的视频不是来自相册，所以我将此方法暴露出来。
调用发现水印添加不成功。没有报错，输出的有地址。

+ (void)export:(AVAsset *)asset range:(CMTimeRange)range type:(ZLExportVideoType)type presetName:(NSString *)presetName renderSize:(CGSize)renderSize watermarkImage:(UIImage *)watermarkImage watermarkLocation:(ZLWatermarkLocation)location imageSize:(CGSize)imageSize effectImage:(UIImage *)effectImage birthRate:(NSInteger)birthRate velocity:(CGFloat)velocity complete:(void (^)(NSString *exportFilePath, NSError *error))complete;

调用方法参数如下

[ZLPhotoManager export:fileAsset range:CMTimeRangeMake(kCMTimeZero, kCMTimePositiveInfinity) type:ZLExportVideoTypeMp4 presetName:AVAssetExportPresetPassthrough renderSize:CGSizeMake(CGFLOAT_MAX, CGFLOAT_MAX) watermarkImage:[UIImage imageNamed:@"plc_12"] watermarkLocation:ZLWatermarkLocationTopLeft imageSize:CGSizeMake(100, 100) effectImage:nil birthRate:0 velocity:0 complete:^(NSString *exportFilePath, NSError *error) {
NSSLog(@"exportFilePath == %@",exportFilePath);
    }];

@xxxIxxxx 你把视频导入相册，然后用demo试一下看是否能成功添加水印，图片格式jpg和png应该都行
