ShanaEncoder ffmpeg声音画面不同步报错分析，日本ts录制音频视频文件修复
日志报错如下，修复方法等待补充分析，其中一有段时间损坏报错，播放过程会产生卡顿暂停情况，此时播放器→一下就好了，转码后输出声音画面不同步和这个有关系
这种问题就是视频文件本身有损坏引起的，修复方法未知
这里有一份群友分享的方法可以参考下：https://bbs.itzmx.com/thread-96251-1-1.html

搜了一圈没搜到片源文件时间戳出错导致时长不对如何修复文件相关的解决办法，后续联系ffmpeg官方技术支持，提供了一个参数让其尝试解决该问题，针对拥有错误信息的ts文件有帮助
可以试试ffmpeg的参数，ShanaEncoder 按f8加入 -async 1 进行测试一下试试，由于天翼云盘的服务器硬盘坏了导致源文件丢失已经无法下载到测试ts文件，有同类ts异常片源文件的可以进行测试一下ffmpeg官方提供的实验性参数
看起来很不错哦，收藏之~~~
谢谢LZ啦！！！ {:3051:}
