Linux/Ubuntu 無法在 vlc 和 mplayer 中調整電影大小

• 使用 Ubuntu 15.10 和 BackBox 4.5 測試。
• 顯卡 i530
• 處理器 i7 6700k
• 用於shuttle xpc sh170r6的主機板

我在使用 vlc 和 mplayer 等程序將電影縮放到任何大小時遇到問題。我可以播放一部電影，但它的大小保持不變。我無法縮放或縮放到全屏。影片周圍的區域用藍色或黑色填充。

我在瀏覽器（chrome/ffox）（例如 youtube）中觀看電影沒有任何問題

除此之外，我沒有遇到任何圖形問題（2D）。

在 Xorg 日誌文件中，我沒有看到任何明顯的錯誤。

我仍然附上它

有誰知道是什麼導致了這個問題？

TIA

這部電影似乎是通過硬體覆蓋播放的，並且無法調整大小。您可以強制您的播放器僅使用 CPU，而不是 GPU（無硬體加速）。這是您的瀏覽器體驗。影片的大小可以以更高的 CPU 負載為代價進行調整。

無需關閉硬體加速/覆蓋。在 VLC 和 Gnome MPlayer 中，在首選項下選擇 x11 作為影片輸出模組。Ubuntu 16.04、i7 6500U、skylake GT2、Intel HD 520 顯卡
