Integration Guide

Environment requirements

To configure the support for HTTP requests, you need to set App Transport Security Settings->Allow Arbitrary Loads to YES in the info.plist file of your project.

Component dependency

Add the GCDWebServer component dependency. 
pod "GCDWebServer", "~> 3.0"
GCDWebServer is a lightweight HTTP server based on GCD and can be used for OS X and iOS. This library also implements extended features such as web-based file upload and WebDAV server.

Using the Player

Declare the variables and then create an instance. The main class of the player is TXCPlayerAdapter, and videos can be played back after it is created.
A fileId is usually returned by the server after the video is uploaded:
1. After the video is published on the client, the server will return a fileId to the client.
2. When the video is uploaded to the server, the corresponding fileId will be included in the notification of upload confirmation.
If the file already exists in Tencent Cloud, you can go to Media Assets and find it. After clicking it, you can view relevant parameters in the video details on the right.
NSInteger appId; //// `appid` can be applied for in Tencent Cloud VOD
NSString *fileId;
// `psign` is a player signature. For more information on the signature and how to generate it, visit https://www.tencentcloud.com/document/product/266/42436?from_cn_redirect=1.
NSString *pSign = self.pSignTextView.text;

TXCPlayerAdapter *adapter = [TXCPlayerAdapter shareAdapterWithAppId:appId];
Request the video information and play back the video:
id<ITXCPlayerAssistorProtocol> assistor = [TXCPlayerAdapter createPlayerAssistorWithFileId:fileId pSign:pSign];
[assistor requestVideoInfo:^(id<ITXCPlayerAssistorProtocol> response, NSError *error) {
    if (error){
        NSLog(@"create player assistor error : %@",error);
        [self.view makeToast:error.description duration:5.0 position:CSToastPositionBottom];
        return;
    }
    [weakSelf avplayerPlay:response]; // Play back the video
}];



- (void)avplayerPlay:(id<ITXCPlayerAssistorProtocol>)response
{
    AVPlayerViewController *playerVC = [[AVPlayerViewController alloc] init];
    self.playerVC = playerVC;
    TXCStreamingInfo *info = response.getStreamingInfo;
    AVPlayer *player = [[AVPlayer alloc] initWithURL:[NSURL URLWithString:info.playUrl]];
    playerVC.player = player;
    playerVC.title = response.getVideoBasicInfo.name;
    [self.navigationController pushViewController:playerVC animated:YES];

    [player addObserver:self forKeyPath:@"status" options:NSKeyValueObservingOptionNew context:nil];
}
Terminate the player after use:
[TXCPlayerAdapter destroy];
