前置条件
需要Mac上已经安装Homebrew、Git、yasm
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install git
brew install yasm
下载ijkplayer
在任意位置创建一个文件夹,打开终端并cd到此文件夹,然后按照下述命令进行代码的clone。
ijkplayer官方Github地址
git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-ios
cd ijkplayer-ios
git checkout -B latest k0.8.8
支持RTSP
如果不需要支持RTSP可跳过此部分,到“编译工程”部分
- 修改ijkplayer-ios/config下的module-lite.sh ,生成新的 module.sh
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --disable-protocol=rtp"
找上到述行,并修改为以下内容并保存(即允许rtp、打开rtsp音视频分离器)。
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-protocol=rtp"
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-demuxer=rtsp"
直接删除module.sh或cd到ijkplayer-ios/config目录后,使用以下命令删除
rm module.sh
删除后重新生成module.sh
ln -s module-lite.sh module.sh
- 修改 ijkplayer-ios/ijkmedia/ijkplayer目录下的ff_ffplay.c
在ff_ffplay.c文件约第336行,将packet_queue_get_or_buffering方法修改为下述内容:
static int packet_queue_get_or_buffering(FFPlayer *ffp, PacketQueue *q, AVPacket *pkt, int *serial, int *finished)
{
// assert(finished);
// if (!ffp->packet_buffering)
// return packet_queue_get(q, pkt, 1, serial);
while (1) {
int new_packet = packet_queue_get(q, pkt, 0, serial);
if (new_packet < 0)
return -1;
else if (new_packet == 0) {
if (q->is_buffer_indicator && !*finished)
ffp_toggle_buffering(ffp, 1);
new_packet = packet_queue_get(q, pkt, 1, serial);
if (new_packet < 0)
return -1;
}
if (*finished == *serial) {
av_packet_unref(pkt);
continue;
}
else
break;
}
return 1;
}
编译工程
回到ijkplayer-ios路径下,逐一执行下述命令。
./init-ios.sh
cd ios
./compile-ffmpeg.sh clean
./compile-ffmpeg.sh all
以上命令会创建iOS工程、下载并编译ffmpeg。
可能会遇到下述错误:
- 报错"xcrun -sdk iphoneos clang is unable to create an executable file.",运行命令行
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer/
后重新编译
生成Framework
打开ijkplayer-ios/ios/IJKMediaPlayer目录下的IJKMediaPlayer.xcodeproj,选择IJKMediaFramework,将Scheme的Build方式改为Release后,分别将设备选为模拟器和真机各编译一次。此时可见工程下的Products目录中IJKMediaFramework.framework已存在,Show in Finder并cd到文件所在目录,执行以下命令合并两个Framework
lipo -create Release-iphoneos/IJKMediaFramework.framework/IJKMediaFramework Release-iphonesimulator/IJKMediaFramework.framework/IJKMediaFramework -output IJKMediaFramework
集成
将IJKMediaFramework.framework拖拽到你的工程,并添加以下依赖库
AudioToolbox.framework | AVFoundation.framework | CoreGraphics.framework |
---|---|---|
CoreMedia.framework | CoreVideo.framework | libbz2.tbd |
libz.tbd | MediaPlayer.framework | MobileCoreServices.framework |
OpenGLES.framework | QuartzCore.framework | UIKit.framework |
VideoToolbox.framework | libc++.tbd |
调用示例如下:
#import <IJKMediaFramework/IJKMediaFramework.h>
@interface ViewController ()
@property(nonatomic, strong) IJKFFMoviePlayerController *player;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
NSURL *url = [NSURL URLWithString:@"rtsp://10.1.3.146/ch5"];
IJKFFOptions *options = [IJKFFOptions optionsByDefault];
self.player = [[IJKFFMoviePlayerController alloc] initWithContentURL:url withOptions:options];
[self.view addSubview:self.player.view];
[self.player.view mas_makeConstraints:^(MASConstraintMaker *make) {
make.edges.mas_equalTo(self.view);
}];
[self.player prepareToPlay];
[self.player play];
}
@end
