不大，网络上的，时长就一两分钟。请问这个问题是否有解决办法呢？ @raymond1012

raymond1012 commented 7 years ago

先debug下是不是卡在mov.c 的mov_read_header

zhanggao commented 7 years ago

刚在mov_read_header里面加了log。在视频加载出来之前release，并没有走到 mov_read_header 这个函数里面。正常播放后再release，是进了mov_read_header的，正常播放时mov_read_header函数大概耗时500毫秒。 release会卡顿好几秒，有时候5s以上。看起来跟mov_read_header没什么关系。

raymond1012 commented 7 years ago

有调用mov_probe吗？

s->io_open 这句走到了 options.c的io_open_default函数里面，卡在了 return ffio_open_whitelist();这句。

执行 ffio_open_whitelist 这个函数的过程中走进了 http_read_header ，但http_read_header 这个函数没有卡住，瞬间执行完了。

是卡在 http_open_cnx 里了。

cur_auth_type       = s->auth_state.auth_type;
cur_proxy_auth_type = s->auth_state.auth_type;
// 貌似是这句代码比较耗时
location_changed = http_open_cnx_internal(h, options);
if (location_changed < 0)
    goto fail; // 非正常情况走进了这里。

当 http_open_cnx 函数没执行完就调用了release，就会导致release卡顿比较长的时间。

AlanJaver commented 7 years ago

确实遇到过_release和_reset两个方法造成的ANR，貌似是释放连接比较慢。这个如果java层开个线程去做，不知道会不会有其他隐患？

Tipsyume commented 7 years ago

@AlanJaver 我现在就是使用线程做释放，出现很多问题

Tipsyume commented 7 years ago

@zhanggao 你的问题解决了没，我现在也遇到这个问题，使用线程池做释放，还没彻底解决这个问题

JoeSteven commented 7 years ago

@Tipsyume 同为现在也遇到这个问题，放倒异步线程里面释放，用户反馈还是会anr

zhanggao commented 7 years ago

@Tipsyume @JoeSteven 我这边把ip解析改了就没这问题了，设置成只解析ipv4。你们可以搜下关于ipv6解析卡的问题。

yueyetv commented 6 years ago

@zhanggao 在我们公司的网络下解析非常慢，是否也有可能是IPV6造成的，具体怎么检查

zhanggao commented 6 years ago

禁止ipv6的解析，或者放自线程释放都能解决。

1、 https://github.com/Bilibili/FFmpeg/blob/master/libavformat/tcp.c#L106 hints.ai_family = AF_UNSPEC;表示先解析ipv6，超时再解析ipv4 hints.ai_family = AF_INET;表示只解析ipv4 2、子线程释放player的时候需要注意多线程的引用别乱掉了，java层实现。只需要把player的reset release放到子线程执行。 https://github.com/Bilibili/ijkplayer/blob/master/android/ijkplayer/ijkplayer-example/src/main/java/tv/danmaku/ijk/media/example/widget/media/IjkVideoView.java#L723 修改L723到L724

final IMediaPlayer tempPlayer = mMediaPlayer;
// mMediaPlayer.pause(); // 如果下面的释放放线程池里执行，可能执行时间比较靠后，也可以先尝试暂停。
mMediaPlayer = null;
new Thread(new Runnable() {
    tempPlayer.reset();
    tempPlayer.release();
}).start();

linjiansheng commented 6 years ago

@zhanggao hints.ai_family = AF_UNSPEC;表示先解析ipv6，超时再解析ipv4 上面你的注释不准确吧(><) addrinfo_one_by_one 和 addrinfo_timeout 配合使用，不需要去手动改代码，就可以达到先解析ipv4在解析ipv6的类似效果 - -

lgengsy commented 5 years ago

@zhanggao 你放到子线程中处理，在player释放的过程中如果重新打开一个视频会不会出问题。现在新打开的这个player会被停掉吧。

zhanggao commented 5 years ago

@zhanggao 你放到子线程中处理，在player释放的过程中如果重新打开一个视频会不会出问题。现在新打开的这个player会被停掉吧。

不会，打开新的视频，new出了新的player实例；tempPlayer引用的是老的实例，子线程里是释放老的实例。

你好, 请问有遇到其他anr问题么？现在我还遇到了播放视频退出时anr， getDuration anr， _stop anr， _setVideoSurface anr。

zhanggao commented 5 years ago

@oncealong 大面积使用没有遇到其它anr。只遇到释放anr，只有在没加载卡顿的，没加载出来的时候调用释放才会anr。

DysaniazzZ commented 5 years ago

@zhanggao 1、禁止 IPV6 的解析也并不能杜绝 ANR 的发生。我们线上发现有些视频源会频繁发生 ANR，如论使用系统播放器还是 ijk，都会发生。eg: http://lssplay.tcgqxx.com/qxdq/5a6049403b86c.m3u8?auth_key=1831619648-e8ffb6a1e5cb544f03bf3aba746638da 2、子线程释放播放器的操作会有副作用。测试发现，当释放一个播放器的同时播放下一个源，开始播放时可能会出现画面卡在上一个视频源，而音频播放的当前视频源。

ChinaZeng commented 4 years ago

@DysaniazzZ 这个问题有解吗，老哥

zhanggao commented 4 years ago

@ChinaZeng 我这边放子线程释放是没什么问题的，用很久了。

@zhanggao 在网速超级慢的情况下，放子线程里释放不会anr，但是有概率报错SIGABRT的错误，释放完差不多等了2分钟。https://github.com/Bilibili/FFmpeg/blob/master/libavformat/tcp.c#L106 hints.ai_family = AF_UNSPEC;表示先解析ipv6，超时再解析ipv4 hints.ai_family = AF_INET;表示只解析ipv4 修改完之后重新编译so文件，没有起到效果，释放的时候还是存在耗时。

有时候 IjkVideoView.release(true) 方法耗时好几秒 #3048
