使用 VLC 播放视频时出现质量差和播放问题

我在使用 VLC 或其他播放器播放 H.264（未测试过）编码的视频时遇到了问题（测试过 MPlayer、Totem 不播放视频只播放声音）。我确定这是驱动程序的问题，但我不知道如何修复它。我尝试安装 AMD 的专有驱动程序，但重启后我无法登录（只能登录终端）。我的显卡是 AMD Radeon HD 8 系列。我不知道这是否相关，我使用 nomodeset 选项启动。感谢您的帮助。

答案1

对我来说，SMPlayer 效果最好，它可以完美播放 h264。你安装了吗sudo apt-get install ubuntu-restricted-extras？安装新驱动程序后，你需要配置 X 才能正确使用它。如何配置AMD和这也能派上用场。

答案2

感谢@JohnnyD，我已成功通过手动安装 Catalyst 13.4 解决了我的问题（这)，然后编辑 grub 选项。将 nomodeset 选项更改为 acpi_backlight=vendor。

答案3

您是否尝试过为您的特定安装安装“Ubuntu Restricted Extras”？这些将为您提供一系列流行的格式编解码器和插件，让您可以毫无问题地播放大多数媒体格式。我不确定您使用的是哪个版本的 Ubuntu，但假设您使用的是 12.04 LTS，您将使用以下命令：

sudo apt-get install ubuntu-restricted-extras
