- 使用 Ubuntu 15.10 和 BackBox 4.5 进行测试。
- 显卡 i530
- 处理器 i7 6700k
- 航天飞机xpc sh170r6使用的主板
我在使用 vlc 和 mplayer 等程序将电影缩放到任意尺寸时遇到问题。我可以播放电影，但它的大小保持不变。我无法缩放或缩放至全屏。视频周围的区域充满蓝色或黑色。
我在浏览器（chrome/ffox）中观看电影没有遇到任何问题（例如youtube）
除此之外我没有遇到任何图形问题（2D）。
在 Xorg 日志文件中，我没有看到任何明显的错误。
我还是附上它
有人知道是什么原因导致这个问题吗？
TIA

答案1
无需关闭硬件加速/叠加。在 VLC 和 Gnome MPlayer 中，在首选项下选择 x11 作为视频输出模块。 Ubuntu 16.04、i7 6500U、skylake GT2、英特尔 HD 520 显卡
答案2
这部电影似乎是通过硬件覆盖播放的，并且无法调整大小。您可以强制播放器仅使用 CPU，而不使用 GPU（无硬件加速）。这是您的浏览器体验。视频的大小会随着 CPU 负载的增加而调整。
