我正在尝试上传视频。我已将视频文件保存为MP4文件,如下所示:
NSString *fileName = [NSString stringWithFormat:@"chatVideo-%d.mp4",arc4random()%1000];
NSString *myPathDocs = [documentsDirectory stringByAppendingPathComponent:fileName];
NSURL *videoURL = [NSURL fileURLWithPath:myPathDocs];
AVAssetExportSession *exportSession = [AVAssetExportSession exportSessionWithAsset:asset2 presetName:AVAssetExportPresetHighestQuality];
exportSession.outputURL = videoURL;
exportSession.outputFileType = AVFileTypeMPEG4;
NSData *videodata =[NSData dataWithContentsOfURL:videoURL];
我调用了图谱API以上传到Facebook:
[parameters setValue:videoData forKey:@"source"];
[parameters setValue:thumbData forKey:@"thumb"];
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me/videos"
parameters:parameters
HTTPMethod:@"POST"]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if ([error.userInfo[FBSDKGraphRequestErrorGraphErrorCode] isEqual:@200]) {
NSLog(@"permission error");
}
}];
但我收到此错误:
抱歉,您选择的视频文件格式不支持。
最佳答案
是的,经过很长一段时间,我才找到答案:
[parameters setValue:videoData forKey:@"source"];
肯定是:
[parameters setValue:videoData forKey:@"video.mp4"];
我讨厌Facebook文档==!。
