A brief analysis of several solutions for video playback in iOS

1、AVPlayer

(1) Pros and cons

Advantages: You can customize the UI and control it

Disadvantages: Simple playback, no control UI (progress, pause, play, etc. buttons), and if you want to display the playback interface, you need to use AVPlayerLayer to add layers to the layer you need to display.

(2) Realize remote video playback

Implement playback function (only sound)

1. Import the framework

#import <AVFoundation/>

2. Create an AVPlayer object through a remote URL

NSURL *remoteURL = [NSURL URLWithString:@"/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4"];
 _player = [AVPlayer playerWithURL:remoteURL];

3. Start playing

[ play];

There is a problem: only sound can be played, no images can be seen

Solution: You need to use the AVPlayerLayer object to create a layer based on the player and add it to the view

Show video

4. Create AVPlayerLayer based on player object

 AVPlayerLayer *layer = [AVPlayerLayer playerLayerWithPlayer:];

5. Set the layer's frame

   = CGRectMake(0, 0, ,  * 9 / 16);

6. Add the layer to the layer of the View that needs to be displayed

  [ addSublayer:layer];

2、MPMoviePlayerController

(1) Pros and cons

Advantages: The built-in playback control UI (progress bar, previous, next, pause), does not need to be added manually

Disadvantages: Cannot customize the UI

Only this controller view can be added to other views for display

This controller is not a view controller and cannot be popped up directly

The player's playback status is told to the outside world through notification

(2) Video playback implementation steps

1. Import the framework

#import <MediaPlayer/>

2. Create a controller based on the URL MPMoviePlayerController

NSURL *remoteURL = [NSURL URLWithString:@"/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4"];
 _moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:remoteURL];

3. Set the play view frame and add it to the view that needs to be displayed.

 // Set the frame of the playback view  = CGRectMake(0, 0, ,  * 9 / 16);
 // Set the play view control style  = MPMovieControlStyleFullscreen;
 // Add play view to the view to be displayed [ addSubview:];

4. Play

[ play];

3、MPMoviePlayerViewController

(1) Pros and cons

Advantages: The built-in playback control UI does not need to be added manually

This controller is a view controller, which can be popped up and pressed on the stack.

You can also manually resize the view and add it to other views

Disadvantages: Cannot customize the UI

(2) Video playback implementation steps

1. Import the framework

#import <MediaPlayer/>

2. Create a controller based on the URL MPMoviePlayerViewController

NSURL *remoteURL = [NSURL URLWithString:@"/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4"];
 _playerVC = [[MPMoviePlayerViewController alloc] initWithContentURL:remoteURL];

3. The controller is popped up directly modally (or: set the play view frame and add it to the view that needs to be displayed)

[self presentViewController: animated:YES completion:^{
   [ play];
 }];

4. Play

[ play];

4. For the second and third implementation solutions, after iOS9.0, AVPlayerViewController is used uniformly

(1) Pros and cons

Advantages: The built-in playback control UI does not need to be added manually

This controller is a view controller, which can pop up and press the stack.

You can also manually resize the view and add it to other views

Disadvantages: Cannot customize the UI

(2) Video playback implementation steps

1. Import the framework

 #import <AVFoundation/>
 #import <AVKit/>

2. Create AVPlayer based on URL

  NSURL *remoteUrl = [NSURL URLWithString:@"/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4"]; 
  AVPlayer *player = [AVPlayer playerWithURL:remoteUrl];

3. Create an AVPlayerViewController controller based on AVPlayer

  _playerVc = [[AVPlayerViewController alloc] init];
  _playerVc.player = player;

4. Set the play view frame and add it to the view that needs to be displayed.

   = CGRectMake(0, 0, ,  * 9 / 16);
  [ addSubview:];

5. Play

  [ play];

Merge of Step 4 and Step 5:

[self presentViewController: animated:YES completion:nil];
