Ijkplayer: 视频缓冲和分段播放问题

Created on 17 Apr 2015  ·  72Comments  ·  Source: bilibili/ijkplayer

感谢作者贡献了这么好的项目！我在使用的时候碰到了一些问题：
1、在使用IJKFFMoviePlayerController的暂停时缓冲也跟着暂停了，我用NSTimer去输出缓冲也是不变
2、处理多段播放能否使用另一个FFPlayer进行预缓冲和切换
3、最终缓冲playableDuration与视频的duration会有0.4～0.6秒的差距，这个是否是正常的
谢谢

视频缓冲问题找到了，是我MAX_QUEUE_SIZE设置的太小了，导致直接缓冲好停止在那里

Zard1096 picture Zard1096 on 17 Apr 2015
  1. 理论上可以，但是我没试过有什么问题。
  2. 不正常，不过在我接受范围之内。

最终缓冲playableDuration我找到问题了，在ff_ffplay.c中的 static int read_thread(void *arg)中会在数据加载完后设置eof = 1，然后走continue，之后缓冲 ffp->playable_duration_ms = buf_time_position; 就不执行了，可以考虑把缓冲代码调到前面或者在加载成功的eof = 1处加入
ffp->playable_duration_ms = ffp_get_duration_l(ffp);
如果MAX_QUEUE_SIZE设置小一点还好，会有0.4~0.6s的误差，如果设置成50 * 1024 * 1024可能会有5～10+s的误差

分段播放(处理网络分段)上我还是有问题，在获得结束通知时再切换FFPlayer一定会造成1s左右的卡顿，我换成切换IjkMediaPlayer在显示时报错，然后看了以前的关于分段的issue #38 有一个concat协议，但是网上查了很久也没有发现有相关iOS代码，我想请教一下用concat处理分段具体应该怎么做 @bbcallen

Zard1096 picture Zard1096 on 22 Apr 2015

http://www.ffmpeg.org/ffmpeg-formats.html#Syntax

bbcallen picture bbcallen on 22 Apr 2015

这一段Syntax我看的很糊涂，我是按着这样的格式作为我的FFMrl
concat:url1|url2...
但是在读取的时候分段虽然都有加载，但是无法自动播放下一段，format_control_message也没有被调用
如果用
file 'url1'
file 'url2'
又无法识别
有没有一个相关示例代码能让我了解一下 @bbcallen

Zard1096 picture Zard1096 on 22 Apr 2015

你直接看 libavformat/concatdec.c 的代码吧，很短的。

bbcallen picture bbcallen on 23 Apr 2015

1.跟着ffmpeg源代码走我发现设置url为concat:url1|url2|...是对的，protocol也正确读出是concat，不过在执行ffurl_connect的uc->prot->url_open2(uc,uc->filename,uc->flags,options)报错走了url_open。
2.我对format_option设置 ffconcat , version 1.0但是返回没有ffconcat这个选项，而在concatdec的concat_probe对应的是AVProbeData的buf开头有ffconcat version 1.0,我想问一下我具体该在哪里设置ffconcat version 1.0？
3.我在部分资料中查到concat支持的格式很少，而在官方文档中又看到了对flv格式,我想问一下concat是否支持mp4,m4a,flv,f4a等格式。
谢谢 @bbcallen

Zard1096 picture Zard1096 on 24 Apr 2015

因为ffmpeg的url有长度限制，无法通过url传入所有分段，
所以你需要构造一个 ffconcat 的文件，把分段的时长和url写进一个临时文件，
然后把这个临时文件传给ffmpeg.
概念上类似m3u8, http://en.wikipedia.org/wiki/M3U

理论上，只要压制参数完全相同的分段，都是可以支持。

bbcallen picture bbcallen on 24 Apr 2015

就是我需要写一个txt，url为concat:filepath,或者文件结尾为".ffcat" or ".ffconcat" 对应文件类似于

ffconcat version 1.0
file 'url1'
duration 100
file 'url2'
duration 100
...

绕了太多的弯路，谢谢帮助 @bbcallen

我认真看了一下两位的答案，还有一些不懂。

  1. 例如一个视频有3段分片，在客户端把这三个分片的url和duration按照格式写入一个txt文件中？
  2. 如果是在客户端构造了这个txt文件，那么这个文件怎样传给ffmpeg呢？
  3. 文件中的duration是怎样获取的呢？
    还是这个txt文件是在服务端写好，然后客户端只需要将这个文件的地址当作url传入就可以了呢？

这些问题研究了半天还没有结果，还请各位不吝赐教。

sarahzuo picture sarahzuo on 26 Jun 2015

这个是需要自己去实现的吧，默认应该是不行的，可以使用ffplay测试一下

bolee picture bolee on 30 Jul 2015

1.你可以客户端生成也可以服务端生成，服务端也是传回这个文件url.
2.把这个文件保存的路径url传入ffmpeg即可,地址开头协议可用ffconcat.
3.需要服务器传回每段长度或者想办法获取，也可以不传duration不过这样有可能seek不精准或者无法seek.

Zard1096 picture Zard1096 on 30 Jul 2015

@Zard1096 能否给一个范例的concat文件，我自己试了一个好像不行，文件名是test.txt，内容是：
ffconcat version 1.0
file 'http://xxxx'
duration 186
file 'http://xxx'
duration 210

调用的时候采用mVideoPath = "ffconcat:/storage/emulated/0/test.txt"
还是会提示无法播放

leonard0629 picture leonard0629 on 7 Aug 2015

路径应该设为 ffconcat://fileurl,ffconcat是协议
或者你尝试将文件命名为 *.concat 或 *.ffconcat

Zard1096 picture Zard1096 on 7 Aug 2015

@Zard1096 请给一个测试文件吧

Android4MediaPlayer picture Android4MediaPlayer on 7 Aug 2015

文件构成一样的,没有区别,你截一下日志我帮你看一下吧
还有concat需要设置option safe 0

Zard1096 picture Zard1096 on 7 Aug 2015

@Zard1096
ffconcat version 1.0
file http://hot.vrs.sohu.com/ipad2457075_4648026007963_5668396.m3u8?plat=17&prod=app
duration 2935
file http://hot.vrs.sohu.com/ipad2457075_4648026007963_5668396.m3u8?plat=17&prod=app
duration 2935
报错 Unsafe file name 'http://hot.vrs.sohu.com/ipad2457075_4648026007963_5668396.m3u8?plat=17&prod=app'

Android4MediaPlayer picture Android4MediaPlayer on 7 Aug 2015

@Zard1096 不会只能本地文件吧

Android4MediaPlayer picture Android4MediaPlayer on 7 Aug 2015

unsafe file name 要设置设置option safe 0
你为什么要在ffconcat中设置m3u8?有m3u8直接设置m3u8就能读了。
还有在ffconcat中的文件压制码率必须一样。
ffconcat中再包一层HLS协议我不确定能不能读。
iOS是有新版好像变成ijkmp_set_option
Android应该是有个类似的setOption的方法

Zard1096 picture Zard1096 on 7 Aug 2015

测试下这个协议，safe是出于什么考虑呢

Android4MediaPlayer picture Android4MediaPlayer on 7 Aug 2015

http://www.ffmpeg.org/ffmpeg-formats.html#Syntax
这是ffmpeg的安全措施

Zard1096 picture Zard1096 on 7 Aug 2015

safe设置为0，还是一样的错误

Android4MediaPlayer picture Android4MediaPlayer on 7 Aug 2015

@Zard1096 给个测试链接吧

Android4MediaPlayer picture Android4MediaPlayer on 7 Aug 2015

我并没有服务器,测试concat我都是本地组装或者挂在自己mac的Apache上测的
还是显示unsafe我估计你是没设置对
你自己扔到服务器上改一下ip测测看吧

@Zard1096 @Android4MediaPlayer 我用 Zard1096提供的concat文件 测试了 报错：
/storage/emulated/0/ffmpeg_concat/ffconcat.concat: Operation not permitted

不需要修改源码的，ffmpeg就本身支持

@Android4MediaPlayer 我测试成功了，但是 播放的时候 发现个问题，就是在播放分段视频的时候 播放一段时间会暂停，当点击 播放按钮的时候 他还是暂停的， 除非 seek 才会播放。你遇到过 这个问题么？

@Zard1096 请问，我也写了一个.concat文件，然后将该文件本地的URL作为参数，可是视频不播放，报错是：ffconcat://Users/mac/Library/Developer/CoreSimulator/Devices/746273E7-5F1A-4542-A98B-093449641FAB/data/Containers/Data/Application/CDCD7E95-7532-4AFD-9205-CD0CBA4836B7/Documents: Protocol not found
这是什么原因呀，我的.concat文件内容是http://pan.baidu.com/s/1i557xhb

DanielYQ picture DanielYQ on 29 Jul 2016

@DanielYQ
协议为 concat:// , protocol是concat不是ffconcat
还有一个问题可能存在的问题是你文件好像只到了路径,没有到最终的文件

追加: 下了你的文件看了一下,第一段url错了,视频能否播放就由你自己验证了,格式没问题

检查ffmpeg的config是否没有开启concat

singno picture singno on 24 Aug 2016

@Zard1096 看了您的回复，我有一些问题想请教：如果获取到分段视频的地址了，但不知道视频每个分段的长度，该如何写concat这个文件？可否不指定duration？
搜索了很多资料，ijkplayer还支持m3u8（m3u8貌似可以不指定duration也可以播放），若要本地加载m3u8该如何处理？谢谢

yujieace picture yujieace on 6 Sep 2016

@yujieace 请注意看之前的回答:

3.需要服务器传回每段长度或者想办法获取，也可以不传duration不过这样有可能seek不精准或者无法seek.

m3u8里面需要有每段时长信息的.
本地加载concat或者m3u8都需要你自己把这文件临时创建出或者打在包中.
m3u8详见https://en.wikipedia.org/wiki/M3U
concat详见http://www.ffmpeg.org/ffmpeg-formats.html#Syntax

Zard1096 picture Zard1096 on 7 Sep 2016

@Zard1096 谢谢，看您的回复，不传duration回导致seek不准确，也就是无法快进快退是吗？
另外，我按照格式制作了concat文件，内容如下,没有设置duration：

你没有把player的视图添加到你需要显示的视图中

Zard1096 picture Zard1096 on 8 Sep 2016

@Zard1096 谢谢，之前贴的代码没有包含添加视图和布局的部分，但实际是添加了的，如下

[IJKFFMoviePlayerController checkIfFFmpegVersionMatch:YES];
    [IJKFFMoviePlayerController setLogLevel:k_IJK_LOG_DEBUG];
    [IJKFFMoviePlayerController setLogReport:YES];
    self.player=[[IJKFFMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:_url] withOptions:[IJKFFOptions optionsByDefault]];
    IJKFFMoviePlayerController *player=(IJKFFMoviePlayerController *)self.player;
    //[player setPlayerOptionValue:@"0" forKey:@"safe"];
    player.tcpOpenDelegate=self;
    //player.segmentOpenDelegate=self;
    [self.player prepareToPlay];
    [_player setShouldAutoplay:YES];
    _player.scalingMode=IJKMPMovieScalingModeAspectFit;
    self.player.view.frame=self.view.bounds;
    [self.view addSubview:self.player.view];
    [self.player.view mas_makeConstraints:^(MASConstraintMaker *make) {
        make.edges.equalTo(self.view);
    }];

添加了还是出现这个问题

参照一下ijk的demo,添加视图应该在prepareToPlay之前添加

Protocol not found去ffmpeg中把concat协议加上

Zard1096 picture Zard1096 on 21 Sep 2016

@Zard1096

是在实现里加以下代码吗?
IJKFFOptions * options = [IJKFFOptions optionsByDefault];
[options setFormatOptionValue:@"concat,file" forKey:@"protocol_whitelist"];

IJKFFOptions * options = [IJKFFOptions optionsByDefault];
[options setFormatOptionValue:@"concat,file" forKey:@"protocol_whitelist"];

[IJKFFMoviePlayerController checkIfFFmpegVersionMatch:YES];
[IJKFFMoviePlayerController setLogLevel:k_IJK_LOG_DEBUG];
[IJKFFMoviePlayerController setLogReport:YES];
self.player=[[IJKFFMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:self.textView.text] withOptions:options];

self.player.tcpOpenDelegate=self;
[self.player prepareToPlay];
[_player setShouldAutoplay:YES];
_player.scalingMode=IJKMPMovieScalingModeAspectFit;
self.player.view.frame=self.view.bounds;
[self.view addSubview:self.player.view];

加了,效果一样

ffmpeg的config

Zard1096 picture Zard1096 on 21 Sep 2016

@Zard1096
是CONFIG_CONCAT_PROTOCOL吗?

pogong picture pogong on 21 Sep 2016

Android 有人使用吗？ 能在线替换 部分视频 或者 视频中的音频文件吗？ 谢谢~

虽然 closed，但硬是给看呆了。。。Protocol not found 应该是指路径的开头 concat:// 错误吧，路径是类似 file:// 开头吧。。。 concat 只需要把文件拓展名设成 .ffcat 或者 .ffconcat 就可以识别了。
