代码如下:
- (void)convertVideoWithURL:(NSURL *)url
{
NSDate *date = [NSDate date];
NSDateFormatter *dateformatter = [[NSDateFormatter alloc]init];
[dateformatter setDateFormat:@"YYYY-MM-dd-HH-mm-ss"];
NSString *dateName = [dateformatter stringFromDate:date];
NSString *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES).firstObject;
NSString *pathName = [path stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.mp4",dateName]];
NSLog(@"沙盒：%@",pathName);
//转码配置
AVURLAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];
AVAssetExportSession *exportSession= [[AVAssetExportSession alloc] initWithAsset:asset presetName:AVAssetExportPresetMediumQuality];
exportSession.shouldOptimizeForNetworkUse = YES;
exportSession.outputURL = [NSURL fileURLWithPath:pathName];
exportSession.outputFileType = AVFileTypeMPEG4;
[exportSession exportAsynchronouslyWithCompletionHandler:^{
int exportStatus = exportSession.status;
switch (exportStatus) {
case AVAssetExportSessionStatusFailed:
{
// log error to text view
NSError *exportError = exportSession.error;
NSLog (@"AVAssetExportSessionStatusFailed: %@", exportError);
[SVProgressHUD showErrorWithStatus:@"视频压缩失败"];
[SVProgressHUD dismissWithDelay:1.0];
break;
}
case AVAssetExportSessionStatusCompleted:
{
self.videoData = [NSData dataWithContentsOfFile:pathName];
[[NetTool shareDL]upLoadVideoWithURL:@"http://192.168.1.102/php/image.php" paremeter:nil data:self.videoData videoName:[NSString stringWithFormat:@"%@.mp4",dateName] progress:^(NSProgress * _Nonnull uploadProgress) {
[SVProgressHUD showProgress:1.0*uploadProgress.completedUnitCount/uploadProgress.totalUnitCount status:@"正在上传"];
NSLog(@"正在上传%f%%",(1.0*uploadProgress.completedUnitCount/uploadProgress.totalUnitCount)*100);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
[SVProgressHUD showSuccessWithStatus:@"上传成功"];
[SVProgressHUD dismissWithDelay:1.0];
} fail:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
[SVProgressHUD showErrorWithStatus:@"上传失败"];
[SVProgressHUD dismissWithDelay:1.0];
}];
}
}
}];
}[manager POST:url parameters:parameter constructingBodyWithBlock:^(id_Nonnull formData) { [formData appendPartWithFileData:videoData name:@"upimage" fileName:videoName mimeType:@"video/mp4"]; } progress:^(NSProgress * _Nonnull uploadProgress) { progress(uploadProgress); } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { success(task,responseObject); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { fail(task,error); }];
