求助，使用LAV splitter会使部分影片画面比例错误或者无法拉进度条

使用LAV splitter会使部分影片画面比例错误或者无法拉进度条，但使用Haali就一切正常，这是为什么呢？

这个是画面比例错误片子的播放信息与文件信息

这个是无法拉动进度条的播放信息与文件信息，只要一拉动画面就会停止，但播放器还是有响应的。

也许封装的时候没有设置好 SAR、DAR 之类的信息？

realcaptain

回复 Edison 的帖子

那就可能是片源文件封装的问题咯？这样的话，暂时唯一的解决办法就是更改分离器，对么？还好貌似出问题的文件数量不是很大。

你可以试试看去掉 LAV CUVID Decoder 里 Stream Aspect Ratio 的勾。

1. Use Stream Aspect Ratio: If checked, the Aspect Ratio encoded in the stream is used. Note that this value is not always correct, and may cause your Video to be played back with the wrong dimensions – however it is required for content which switches the Aspect Ratio during playback.

btw, lav cuvid decoder 0.8 看来就快出了。

谢谢，去掉Stream Aspect Ratio 的勾后也正常了。
