WebRTC audio and video calls - log output during WebRTC push-pull streaming

WebRTC audio and video calls - log output during WebRTC push-pull streaming

Previously, the iOS side called the ossrs service to implement the push-pull flow process.

Pull flow: https://blog.csdn.net/gloryFlow/article/details/132417602

In the log output related to WebRTC during the push-pull flow, you can see some related description information. RTCCallbackLogger is required for WebRTC logs, and startWithMessageAndSeverityHandler is used to process log output.

1. Realize log output WebRTCLogger

Realize opening the log, and starting startWithMessageAndSeverityHandler will execute the logging callback.

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

The complete code is as follows

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

Two, use WebRTC Logger

We need to start WebRTCLogger, where we use it, and create an instance object.

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

Enable logging where needed

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

Close the day log when the push-pull stream is closed

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

So far, through webRTCLogger, you can see the relevant log information output by WebRTC during the push-pull flow process
