问题描述

PLPlayer RTMP直播流第一次播放，声音与视频对不上，画面与声音差了十几秒

问题出现的环境背景及自己尝试过哪些方法

自己封装了一个播放器，已进入界面就播放。尝试进来先暂停几秒再播放还是有问题。

// 请把代码文本粘贴到下方（请勿用图片代替代码）
PLPlayerOption *option = [PLPlayerOption defaultOption];

[option setOptionValue:@15 forKey:PLPlayerOptionKeyTimeoutIntervalForMediaPackets];
NSURL *url = [NSURL URLWithString:self.url];
self.player = [PLPlayer playerWithURL:url option:option];
self.player.delegate = self;
self.player.playerView.frame = self.frame;
[self addSubview:self.player.playerView];
[self.player play];
//控制视频控件
UITapGestureRecognizer * tap  = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(playerViewTap:)];
[self addGestureRecognizer:tap];

self.cover = [[UIView alloc]init];
self.cover.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.1];
[self addSubview:self.cover];
[self.cover mas_makeConstraints:^(MASConstraintMaker *make) {
    make.left.right.top.bottom.equalTo(self);
}];
//全屏按钮
self.btnFullScreen = [[UIButton alloc]init];
[self.btnFullScreen setImage:[UIImage imageResize:[UIImage imageNamed:@"ico_-full-screen"] andResizeTo:CGSizeMake(25, 25)] forState:(UIControlStateNormal)];
[self.btnFullScreen setImage:[UIImage imageNamed:@"退出全屏"] forState:(UIControlStateSelected)];
[self.cover addSubview:_btnFullScreen];
[self.btnFullScreen mas_makeConstraints:^(MASConstraintMaker *make) {
    make.right.offset(-5);
    make.bottom.equalTo(self->_cover).offset(-10);
}];
[self.btnFullScreen addTarget:self action:@selector(fullScreen:) forControlEvents:(UIControlEventTouchUpInside)];
//视频当前时间
self.currentTime = [[UILabel alloc]init];
self.currentTime.font = [UIFont systemFontOfSize:15];
self.currentTime.text = @"00:00:00";
self.currentTime.textAlignment = NSTextAlignmentLeft;
self.currentTime.textColor = [UIColor whiteColor];
[_cover addSubview:self.currentTime];
[self.currentTime mas_makeConstraints:^(MASConstraintMaker *make) {
    make.left.equalTo(self->_cover).offset(10);
    make.centerY.equalTo(self->_btnFullScreen);
}];

你期待的结果是什么？实际看到的错误信息又是什么？

第一次加载声音跟视频画面能够对应的上
