无法播放多P视频 #49

Closed yejingchen closed 8 years ago

yejingchen commented 8 years ago

系统：Arch，发issue时前刚更新 mpv: 0.15.0，官方源

无法播放B站的多P视频，mpv 一直在提示[cache] Cache is not responding - slow/stuck network connection?，但是带宽是占满的，通过nethogs查看的确是mpv这个进程占用着网速，但是mpv仍然提示网速慢。

在我的系统上一直都可以复现：找一个多P的视频（比如叛逆的鲁鲁修）即可。

终端的输出：

刚刚发现这个问题可能跟 https://github.com/m13253/BiliDan/issues/47 是同一个原因，可是那里提到这只会发生在 2014 年的视频之前，可是我在看2015年的多P视频也会如此

m13253 commented 8 years ago

这个问题我已经了解。正如你看到的那样，我已经联系了 MPV 方面进行修复。 我不知道那边有没有修复好，如果修复好的话，升级到最新版 MPV 就能立即起效。

Solution by @Goshin :

I've met this problem few months ago, and I found controlling the buffer size would be helpful.

Just specify the --cache, --cache-backbuffer, --cache-secs options in the command line for Mpv. It will restrain the buffering of the not playing segments when limited buffer filled in. Refer to https://github.com/Goshin/Yatto/blob/master/src/yatto.py#L144,L145 Official manual: https://mpv.io/manual/stable/

Note that the Mpv needs to fetch the video header of every segment to tell or estimate the playback duration, so the short wait in the beginning is necessary.
