我在我的 iOS 应用程序中集成了 SkyWay SDK ( https://webrtc.ecl.ntt.com/en/ ) 以允许视频 session 。 我的问题是 - 我无法调整远程视频流帧以允许全屏流式传输？当我调整 rcRemote 的 CGRect 时，覆盖在该 View 上的视频不会调整大小，当我更改 maxWidth 和 maxHeight 约束时，框架不会改变。有没有根据您的要求自定义远程视频流帧？

[SKWNavigator initialize:_peer];

SKWMediaConstraints* constraints = [[SKWMediaConstraints alloc] init];
constraints.maxWidth = 960;
constraints.maxHeight = 540;
constraints.cameraPosition = SKW_CAMERA_POSITION_FRONT;

_msLocal = [SKWNavigator getUserMedia:constraints];

最佳答案

用这段代码替换你的代码

SKWMediaConstraints* constraints = [[SKWMediaConstraints alloc] init];
    constraints.maxWidth = 960;
    constraints.maxHeight = 540;

    //  constraints.cameraPosition = SKW_CAMERA_POSITION_BACK;
    constraints.cameraPosition = SKW_CAMERA_POSITION_FRONT;

    _msLocal = [SKWNavigator getUserMedia:constraints];

    //////////////////// END: Get Local Stream   /////////////////////////
    // Initialize views
    if ((nil != self.navigationItem) && (nil == self.navigationItem.title))
    {
        NSString* strTitle = @"Video Conference";
        [self.navigationItem setTitletrTitle];
    }

    CGRect rcScreen = self.view.bounds;
    if (NSFoundationVersionNumber_iOS_6_1 < NSFoundationVersionNumber)
    {
        CGFloat fValue = [UIApplication sharedApplication].statusBarFrame.size.height;
        rcScreen.origin.y = fValue;
        if (nil != self.navigationController)
        {
            if (NO == self.navigationController.navigationBarHidden)
            {
                fValue = self.navigationController.navigationBar.frame.size.height;
                rcScreen.origin.y += fValue;
            }
        }
    }

    // Initialize Local video view
    CGRect rcLocal = CGRectZero;
    if (UIUserInterfaceIdiomPad == [UIDevice currentDevice].userInterfaceIdiom)
    {
        rcLocal.size.width = rcScreen.size.width / 5.0f;
        rcLocal.size.height = rcScreen.size.height / 5.0f;
    }
    else
    {
        rcLocal.size.width = rcScreen.size.height / 5.0f;
        rcLocal.size.height = rcLocal.size.width;
    }
    rcLocal.origin.x = rcScreen.size.width - rcLocal.size.width - 8.0f;
    rcLocal.origin.y = rcScreen.size.height - rcLocal.size.height - 58.0f; // changed from 8 to 78 so to present this view above control views
    rcLocal.origin.y -= self.navigationController.toolbar.frame.size.height;

    // New frames for local and remote video views
    CGRect rcRemoteNew;
    rcRemoteNew.origin.x = 0.0;
    rcRemoteNew.origin.y = 0.0;
    rcRemoteNew.size.width = SCREEN_WIDTH;
    rcRemoteNew.size.height = SCREEN_HEIGHT;

    ////////////  START: Add Remote & Local SKWVideo to View   ///////////
    SKWVideo* vwRemote = [[SKWVideo alloc] initWithFrame:rcRemoteNew];
    [vwRemote setBackgroundColorUIColor blackColor]];
