AKVideoImageView

Motivation

AKVideoImageView was created because I wasn't satisfied with the standard AVPlayer when I was implementing a video background for one of my apps. The main issue is that AVPlayer doesn't let the phone go to sleep mode. Additionally, you can't insensibly start the video from the first frame when the app enters the background. This class solves these problems and has a less noticeable lag when switching from the last to the first frame of the video.

Features

• Allows the phone to go to the sleep mode
• Ability to dynamically switch videos
• Automatically switches to the first frame of video to have a seamless transition when the app returns from the background
• Minimal memory footprint
• Good performance
• Ability to use mp4 files as the video source
• Interface Builder support

Usage

Compressing your video file

Before starting using this class, you need to properly compress the video. Here is an example of libx264 compression options on OS X system using FFmpeg utility:

ffmpeg -i input.mov -vcodec libx264 -level 3.1 -pix_fmt yuv420p -threads 1 -preset placebo -crf 19 -tune film -x264opts colorprim=bt709:transfer=bt709:colormatrix=bt709:fullrange=off output.mp4

Using Interface Builder

Just drag the UIImageView to your UIView and set its class to the AKVideoImageView. In the Attributes Inspector set the Video File Name to the name of your .mp4 video file without extension. See an example project for more info if needed.

Using Code

Objective-C:

#import "AKVideoImageView.h"

NSURL *videoURL = [[NSBundle mainBundle] URLForResource:@"videoName" withExtension:@"mp4"];
AKVideoImageView *videoBG = [[AKVideoImageView alloc] initWithFrame:self.view.bounds
                                                           videoURL:videoURL];
[self.view addSubview:videoBG];
[self.view sendSubviewToBack:videoBG];

Swift:

import AKVideoImageView

let url = Bundle.main.url(forResource: "video_1", withExtension: "mp4")!
let videoView = AKVideoImageView(frame: view.bounds, videoURL: url)!
view.addSubview(videoView)

Dynamically changing video

NSURL *videoURL = [[NSBundle mainBundle] URLForResource:@"anotherVideoName" withExtension:@"mp4"];
self.videoBG.videoURL = videoURL;

Installation

Manually

Just add AKVideoImageView.h and AKVideoImageView.m files to your project.

CocoaPods

Add the following line to your Podfile.

pod "AKVideoImageView", "~> 1.1"
