Usage

To run the Demo project; clone the repo, and run pod install from the VKVideoPlayer directory first. After installed pod, open VKVideoPlayer.xcworkspace in Xcode to run Demo Application.

Installation

VKVideoPlayer is available through CocoaPods, to install it simply add the following line to your Podfile:

pod "VKVideoPlayer", "~> 0.1.1"

Getting Start

Simple way to play Http Live Streaming contents.

VKVideoPlayerViewController *viewController = [[VKVideoPlayerViewController alloc] init];
[self presentModalViewController:viewController animated:YES];
[viewController playVideoWithStreamURL:[NSURL URLWithString:@"http://content.viki.com/test_ios/ios_240.m3u8"]];

Customize

Video Player

It is able to use customized video player view.

self.player = [[VKVikiVideoPlayer alloc] initWithVideoPlayerView:[[VKVikiVideoPlayer alloc] init]];
self.player.delegate = self;
[self.view addSubview:self.player]

Also VKVideoPlayerView has simple way for additional control.

- (void)addSubviewForControl:(UIView *)view;
- (void)addSubviewForControl:(UIView *)view toView:(UIView*)parentView;
- (void)addSubviewForControl:(UIView *)view toView:(UIView*)parentView forOrientation:(UIInterfaceOrientationMask)orientation;

Sample

// Display newButton when screen is landscape mode.
[self.player.view addSubviewForControl:newButton toView:self.player.view forOrientation:UIInterfaceOrientationMaskLandscape]

To cofigure VKVideoPlayer, there are some properties.

@property (nonatomic, assign) BOOL forceRotate;

This property can change behavior of orientation. If UIViewController has only Portrait mode, but it can rotate to Landscape when set it YES.

@property (nonatomic, assign) CGRect portraitFrame;

This property is used when rotate to Portrait by forceRotate. Video player view will be this frame size.

@property (nonatomic, assign) CGRect landscapeFrame;

This property is used when rotate to Landscape by forceRotate. Video player view will be this frame size.

Subtitles

To customize subtitles, there are some way. To change font size, use VKSharedUtility. There are 3 values.

// value accepts @0, @1, @2 or @3;
// @0 : Tiny
// @1 : Medium
// @2 : Large
// @3 : Huge
[VKSharedUtility setValue:@1 forKey:kVKSettingsSubtitleSizeKey];

Or you can override folloing method to customize caption style.

- (DTCSSStylesheet*)captionStyleSheet:(NSString*)color {
  float fontSize = 1.3f;
  float shadowSize = 1.0f;

  switch ([[VKSharedUtility setting:kVKSettingsSubtitleSizeKey] integerValue]) {
    case 1:
      fontSize = 1.5f;
      break;
    case 2:
      fontSize = 2.0f;
      shadowSize = 1.2f;
      break;
    case 3:
      fontSize = 3.5f;
      shadowSize = 1.5f;
      break;
  }

  DTCSSStylesheet* stylesheet = [[DTCSSStylesheet alloc] initWithStyleBlock:[NSString stringWithFormat:@"body{\
    text-align: center;\
    font-size: %fem;\
    font-family: Helvetica Neue;\
    font-weight: bold;\
    color: %@;\
    text-shadow: -%fpx -%fpx %fpx #000, %fpx -%fpx %fpx #000, -%fpx %fpx %fpx #000, %fpx %fpx %fpx #000;\
    vertical-align: bottom;\
    }", fontSize, color, shadowSize, shadowSize, shadowSize, shadowSize, shadowSize, shadowSize, shadowSize, shadowSize, shadowSize, shadowSize, shadowSize, shadowSize]];
  return stylesheet;
}
