无法让Handbrake使用“MP4 Normal”

General Support / Questions Profiles

我是新用户，发现所有使用“MP4 Normal”配置文件的转码最终都调用了 ffmpeg。我在日志里看到 Handbrake 报错，但不太明白原因。以下是日志中的相关片段：

求助！

谢谢，

能否附上你的轉換記錄檔？裡面可能有更多資訊。你有 Nvidia 顯示卡嗎？

我确实有一张Nvidia显卡，虽然是比较老的型号。这里有一个示例转换日志文件的链接：

非常感谢帮助！！

好的，經過大量閱讀後，我猜測 MCEBuddy 正在從 Handbrake 轉向 ffmpeg，以便能搭配我的 Nvidia 顯示卡使用 NVENC。我本來以為我有 QSV，但因為主機板內顯被停用，所以無法使用。

很希望有人能幫我確認這就是目前的狀況。

謝謝！

所以我做了個快速測試，如果我把「硬體編碼」關掉，它就會使用 Handbrake。

我搞不懂的是：a) 如果它平常不是用 Handbrake，是因為找不到 QSV，那 b) 為什麼從上面的日誌看來，即使偵測到了 NVENC，它似乎也沒有用 ffmpeg 去呼叫 NVENC？

這通常是驅動程式某種詭異的問題嗎？我傾向直接關掉硬體編碼，讓它用 Handbrake 就好，但我還是想先把來龍去脈弄清楚…

你說得對！這兩點正是正在發生的情況。你可以從日誌檔案中看到，它偵測到 Nvidia 硬體並優先使用你的編碼器。

你可以：

  1. 停用重新排序（請參閱進階命令）

  2. 在轉換任務的專家設定頁面停用硬體與編碼

  3. 啟用你的 QSV Intel 顯示卡作為主要顯示卡，以便使用 HandBrake 硬體編碼。

7

我遇到了同样的问题，但我似乎找不到“禁用硬件和编码”选项。

如果您進入轉換任務並點擊「進階設定」，然後捲動到畫面最底部，您會找到「專家設定」。點擊該選項後，您會在頁面中間找到「硬體加速」的核取方塊。
