WebRTC音视频通话-WebRTC推拉流过程中日志log输出

之前实现iOS端调用ossrs服务实现推拉流流程。
推流：https://blog.csdn.net/gloryFlow/article/details/132262724
拉流：https://blog.csdn.net/gloryFlow/article/details/132417602

在推拉流过程中的WebRTC的相关日志log输出可以看到一些相关描述信息。在WebRTC日志需要用到RTCCallbackLogger，使用startWithMessageAndSeverityHandler来处理日志输出。

一、实现log输出WebRTCLogger

实现开启log，启动startWithMessageAndSeverityHandler将在执行日志记录回调。

- (void)start {__weak typeof(self) weakSelf = self;[weakSelf.logger startWithMessageAndSeverityHandler:^(NSString * _Nonnull message, RTCLoggingSeverity severity) {DebugLog(@"WebRTCLogger startWithMessageAndSeverityHandler severity:%@,message:%@", [weakSelf loggingSeverityDescription:severity], message);}];
}

完整代码如下

WebRTCLogger.h

#import <Foundation/Foundation.h>
#import <WebRTC/WebRTC.h>
#import <UIKit/UIKit.h>@interface WebRTCLogger : NSObject- (void)start;- (void)stop;@end

WebRTCLogger.m

#import "WebRTCLogger.h"@interface WebRTCLogger ()@property (nonatomic, strong) RTCCallbackLogger *logger;@end@implementation WebRTCLogger- (instancetype)init
{self = [super init];if (self) {self.logger.severity = RTCLoggingSeverityVerbose;// 设置日志记录器RTCSetMinDebugLogLevel(RTCLoggingSeverityVerbose);}return self;
}- (void)start {__weak typeof(self) weakSelf = self;[weakSelf.logger startWithMessageAndSeverityHandler:^(NSString * _Nonnull message, RTCLoggingSeverity severity) {DebugLog(@"WebRTCLogger startWithMessageAndSeverityHandler severity:%@,message:%@", [weakSelf loggingSeverityDescription:severity], message);}];
}- (void)stop {[self.logger stop];
}- (NSString *)loggingSeverityDescription:(RTCLoggingSeverity)severity {if (RTCLoggingSeverityVerbose == severity) {return @"RTCLoggingSeverityVerbose";}if (RTCLoggingSeverityInfo == severity) {return @"RTCLoggingSeverityInfo";}if (RTCLoggingSeverityWarning == severity) {return @"RTCLoggingSeverityWarning";}if (RTCLoggingSeverityError == severity) {return @"RTCLoggingSeverityError";}if (RTCLoggingSeverityNone == severity) {return @"RTCLoggingSeverityNone";}return @"RTCLoggingSeverityNone";
}#pragma mark - Lazy
- (RTCCallbackLogger *)logger {if (!_logger) {_logger = [[RTCCallbackLogger alloc] init];}return _logger;
}@end

二、使用WebRTCLogger

我们需要启动WebRTCLogger，我们在使用地方，创建实例对象。

- (WebRTCLogger *)webRTCLogger {if (!_webRTCLogger) {_webRTCLogger = [[WebRTCLogger alloc] init];}return _webRTCLogger;
}

在需要的地方开启日志log

/**开启RTCLogger*/
- (void)startWebRTCLogger {[self.webRTCLogger start];
}

当关闭推拉流后关闭日子log

/**停止RTCLogger*/
- (void)stopWebRTCLogger {[self.webRTCLogger stop];
}

至此，通过webRTCLogger看到WebRTC在推拉流过程中输出的相关日志信息
