1.nginx rtmp本地推流拉流服務(wù)器搭建
1.1 安裝 （沒安裝brew的同學(xué)，闊以看下這篇文章http://blog.csdn.net/wdd1324/article/details/72769789）
sudo brew install nginx
1.2 查看版本號
nginx -v
安裝成功則返回 nginx version: nginx/1.12.2
1.3 啟動nginx
sudo nginx
如果報錯
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
這個是端口被占用，我們可以殺死其他占用該端口號的進程或者在nginx.conf里修改端口號
先說殺死一個進程的方法线得，后面會說到修改nginx.conf
sudo lsof -i tcp:8080
然后找到PID值斋泄，再kill掉該進程
kill PID
再次啟動 nginx
啟動成功
打開瀏覽器 輸入http://localhost:8080 出現(xiàn)以下界面則成功
1.4 配置nginx
打開終端 cd到nginx目錄下
cd /usr/local/etc/nginx
運行vim 打開nginx.conf
vim nginx.conf
配置rtmp (這里可以不用做配置匆笤，直接用一個端口就能實現(xiàn)推拉净薛，推拉都為同一個端口)
listen為監(jiān)聽的端口號，192.168.4.205是我本地的ip地址啊胶，我用一個src作為推流地址，一個des作為拉流地址垛贤，用ffmpeg將輸入源接入輸出源焰坪，360x480為輸出的分辨率
rtmp {
server {
listen 8080;
chunk_size 4000;
# TV mode: one publisher, many subscribers
application src {
# enable live streaming
live on;
interleave on;
wait_key on;
# publish only from localhost
allow publish all;
#deny publish all;
allow play all;
exec /usr/local/opt/ffmpeg/bin/ffmpeg -i rtmp://192.168.4.205:8080/src -vcodec libx264 -vprofile main -tune zerolatency -s 360x480 -pix_fmt yuv420p -movflags +faststart -preset ultrafast -f flv rtmp://192.168.4.205:8080/des;
}
application des {
live on;
interleave on;
wait_key on;
}
}
}
1.5 重啟nginx
sudo nginx -s reload
這樣就OK啦，可以在mac上通過OBS來推流聘惦，VLC來拉流測試是否成功某饰。
1.6 其他命令與問題
關(guān)閉nginx
sudo nginx -s stop
2.使用LFLiveKit來推流（采用的是h264視頻編碼，ACC的音頻硬編碼）
2.1用Pods來添加LFLiveKit
pod 'LFLiveKit'
2.2LFLiveSession初始化
設(shè)置視頻圖像的分辨率
LFLiveVideoConfiguration *config = [LFLiveVideoConfiguration defaultConfigurationForQuality:LFLiveVideoQuality_Low1];
config.videoSize = CGSizeMake(360, 512); //圖片分辨率
初始化session
_session = [[LFLiveSession alloc] initWithAudioConfiguration:[LFLiveAudioConfiguration defaultConfigurationForQuality:LFLiveAudioQuality_Low] videoConfiguration:config captureType:LFLiveCaptureMaskVideo];
_session.preView= self.livingPushView; //推流預(yù)覽
_session.captureDevicePosition = AVCaptureDevicePositionUnspecified; //設(shè)置為后置攝像頭部凑，默認為前置攝像頭
_session.beautyFace = NO; //是否美顏
_session.running = YES; //是否播放(默認為NO的露乏，不添加則無預(yù)覽圖像)
_session.delegate = self; //設(shè)置代理
2.3LFLive的代理方法
根據(jù)代理可以查看到推流狀態(tài)
- (void)liveSession:(nullable LFLiveSession *)session liveStateDidChange:(LFLiveState)state {
switch (state) {
case LFLiveReady: {
NSLog(@"-準(zhǔn)備");
}
break;
case LFLivePending: {
NSLog(@"-連接中");
}
break;
case LFLiveStart: {
NSLog(@"-已連接");
}
break;
case LFLiveStop: {
NSLog(@"-已斷開");
}
break;
case LFLiveError: {
NSLog(@"-連接出錯");
}
break;
case LFLiveRefresh: {
NSLog(@"-正在刷新");
}
break;
default:
break;
}
}
2.4 開始推流
LFLiveStreamInfo *stream = [LFLiveStreamInfo new];
stream.url = @"rtmp://192.168.4.205:8080/src";
[self.session startLive:stream];
界面消失的時候停止推流
[self.session stopLive];
下面我們看一下拉流
- IJKPlayer
3.1IJKMediaFramework集成
大家闊以看下這片文章，寫得很詳細
http://www.reibang.com/p/1f06b27b3ac0
3.2 IJKMediaFramework集成成功后涂邀，在使用的地方導(dǎo)入
#import <IJKMediaFramework/IJKFFOptions.h>
#import <IJKMediaFramework/IJKMediaPlayer.h>
#import <IJKMediaFramework/IJKFFMoviePlayerController.h>
3.3 配置IJKFFOptions
IJKFFOptions *options = [IJKFFOptions optionsByDefault];
[options setPlayerOptionValue:@"1" forKey:@"an"]; //靜音設(shè)置
[options setPlayerOptionValue:@"1" forKey:@"videotoolbox"]; //開啟硬解碼
[options setPlayerOptionIntValue:10 forKey:@"max-buffer-size"]; //最大緩存
[options setFormatOptionIntValue:10 forKey:@"rtbufsize"]; //緩存
[options setFormatOptionIntValue:2000000 forKey:@"analyzeduration"];
[options setFormatOptionValue:@"nobuffer" forKey:@"fflags"];
[options setFormatOptionIntValue:4096 forKey:@"probsize"];
這是樓主的一些配置參數(shù)瘟仿。
3.4 IJKFFMoviePlayerController初始化
self.player = [[IJKFFMoviePlayerController alloc] initWithContentURLString:_ipstring2 withOptions:options];
self.player.view.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
self.player.view.frame = CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);
self.player.view.backgroundColor = [UIColor blackColor];
self.player.scalingMode = IJKMPMovieScalingModeAspectFill; //縮放模式
self.player.shouldAutoplay = YES; //開啟自動播放（player準(zhǔn)后后，自動播放）
[self.view addSubview:self.player.view];// 添加拉流預(yù)覽視圖
[self.player prepareToPlay];
3.5 添加觀察者比勉，監(jiān)聽拉流狀態(tài)
//監(jiān)聽網(wǎng)絡(luò)狀態(tài)改變
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loadStateDidChange:) name:IJKMPMoviePlayerLoadStateDidChangeNotification object:self.player];
//監(jiān)聽播放網(wǎng)絡(luò)狀態(tài)改變
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playStateDidChange:) name:IJKMPMoviePlayerPlaybackStateDidChangeNotification object:self.player];
//網(wǎng)絡(luò)狀態(tài)改變通知響應(yīng)
- (void)loadStateDidChange:(NSNotification *)notification{
IJKMPMovieLoadState loadState = self.player.loadState;
if ((loadState & IJKMPMovieLoadStatePlaythroughOK) != 0) {
NSLog(@"LoadStateDidChange: 可以開始播放的狀態(tài): %d\n",(int)loadState);
}else if ((loadState & IJKMPMovieLoadStateStalled) != 0) {
NSLog(@"loadStateDidChange: IJKMPMovieLoadStateStalled: %d\n", (int)loadState);
} else {
NSLog(@"loadStateDidChange: ???: %d\n", (int)loadState);
}
}
//播放狀態(tài)改變通知響應(yīng)
- (void)playStateDidChange:(NSNotification *)notification{
switch (_player.playbackState) {
case IJKMPMoviePlaybackStateStopped:
NSLog(@"IJKMPMoviePlayBackStateDidChange %d: stoped", (int)_player.playbackState);
break;
case IJKMPMoviePlaybackStatePlaying:
NSLog(@"IJKMPMoviePlayBackStateDidChange %d: playing", (int)_player.playbackState);
break;
case IJKMPMoviePlaybackStatePaused:
NSLog(@"IJKMPMoviePlayBackStateDidChange %d: paused", (int)_player.playbackState);
break;
case IJKMPMoviePlaybackStateInterrupted:
NSLog(@"IJKMPMoviePlayBackStateDidChange %d: interrupted", (int)_player.playbackState);
break;
case IJKMPMoviePlaybackStateSeekingForward:
case IJKMPMoviePlaybackStateSeekingBackward: {
NSLog(@"IJKMPMoviePlayBackStateDidChange %d: seeking", (int)_player.playbackState);
break;
}
default: {
NSLog(@"IJKMPMoviePlayBackStateDidChange %d: unknown", (int)_player.playbackState);
break;
}
}
}
3.6 界面消失的時候劳较，關(guān)閉播放器
[self.player stop];
[self.player shutdown];
