测试了一个直播码流，发现播放10秒钟不到，就画面静止再也不能播放了。log如下：

请指教如何解决！

使用stable-n010版本，去掉do-while(0),增加以下代码
if (is->audioq.size > 50 &&
is->videoq.size >5) {
ffp_toggle_buffering(ffp, 0);
}
PS：这个值是否是合适的？

目前可以播放，但是播放期间会经常停顿一下，不算流畅（大概5～10秒停顿1～2秒，网络环境还算不错）。后续是否会考虑增加缓存播放呢，来处理直播流卡顿的问题。
谢谢！

直播流后面会考虑优化，现在没怎么接触过，所以我也没什么经验。

最近还在查看这个问题，发现在读数据的时候会进入这个条件：
if ((!is->paused || completed) &&
(!is->audio_st || is->audio_finished == is->audioq.serial) &&
(!is->video_st || (is->video_finished == is->videoq.serial && is->pictq_size == 0)))
然后会做seek的动作，在直播流中一做seek就挂住了。
去掉ffp_notify_msg1(ffp, FFP_MSG_COMPLETED);不做seek动作，可是在av_read_frame的返回却一直是AVERROR_EOF，无法恢复了。

现在想请教两个问题，来帮助理清思路找出解决方法。
1.if ((!is->paused || completed) &&
(!is->audio_st || is->audio_finished == is->audioq.serial) &&
(!is->video_st || (is->video_finished == is->videoq.serial && is->pictq_size == 0)))这个条件是判断什么的？当finished==serial时说明了什么？

2.ffp_check_buffering_l是一个什么策略？

谢谢。期待你的解答。

问题1：是说明队列中没有数据了。

av_read_frame读取又一直是失败状态，所以无法恢复了。

那么是说明导致av_read_frame一直读取失败呢？网络是正常的，每次播放5秒左右就出现问题。重新打开又是只能播放5秒。
所以现在表面问题可以定位在是什么导致av_read_frame读取失败并且不能恢复。

这个有时效性，每次能有效一周。我debug发现和ffmpeg的源码有关，对hls的解析和重定向可能存在bug。我继续跟踪中。

发生seek以前就已经遇到错误了。

  1. 请把刚连上时，输出的视频编码信息贴出来，
  2. 请把m3u8的文本内容wget下来，贴在这里
  3. 如果是嵌套的m3u8，麻烦嵌套的m3u8文本也贴出来。

是ffmpeg版本的问题，建议升级到最新版本，问题解决。
