在Media Player Classic中,我找到了一种以编程方式跳转到视频/音频中某个点的方法,可以避开Go To...框。
跳转距离可在“选项”→“调整”中找到,
HKEY_CURRENT_USER\Software\MPC-HC\MPC-HC\Settings(JumpDistL/JumpDistM/JumpDistS)。

我要做的是在Media Player Classic的地址空间中找到跳转距离,并设置较大跳转距离的值,例如
如果将其应用于耗时,您将获得所需的时间。

然后,我发送带有参数WM_COMMAND/903904消息(全部通过AutoHotkey。我通过检索/解析Edit控件的内容来获得耗时。)

因为跳跃是相对于当前点的,所以它是不精确的,
并在正确时间的一秒内到达,但没有到达
每次都在完全相同的位置。

有没有更直接的方法可以做到这一点,如果没有,
任何Media Player Classic用户/程序员
考虑在论坛上进行讨论,引入新的WM_COMMAND消息
允许跳转到点(以毫秒为单位),
或检索列出的数值here
(statepositiondurationvolumelevelmutedplaybackratereloadtime)。
(发现here的方法太慢,无法准确获取时间,并且需要设置特殊选项)。

最佳答案

多亏来自wOxxOm的消息,在问题下方,
我已经能够创建此AutoHotkey脚本,
解决了我原来的问题:
以编程方式在Media Player Classic中设置耗时,
直接使用,无需使用Go To...框。

它还解决了检索问题
有关视频的信息。

热键是:
-Ctrl + Q启动MPC API,
-Ctrl + W检索信息,
-跳到视频途中的数字键。
