在 Iceweasel 下的 YouTube 中没有带有 HTML 5 播放器的视频

Question

今天，我注意到在使用 HTML 5 播放器（在http://youtube.com/html5 上启用）观看 YouTube 视频时没有视频（音频在那里）。

如果我使用 Flash 播放器，一切正常，但我宁愿避免它。

我gstreamer安装的是：

看起来我缺少一个编解码器，但我不知道是哪个。我正在使用 Debian“测试”，Iceweasel 26.0。该怎么办？

Answer 1

您需要安装该gstreamer0.10-ffmpeg软件包。

然后，要查看它是否有效，请访问http://youtube.com/html5并查看 旁边是否有绿色勾号H.264。

[编辑] 在最近的 Debian 版本 (>= 8.0) 上，您需要 gstreamer1.0-libav
