我有 CHM 文件，其中包含 SWF 视频。
我想用 MP4 转换它并创建新的 CHM 文件。
已转换，工作正常。但我找不到任何像原来那样将视频文件包含到 CHM 中的程序。我尝试过例如 HTML Help Workshop。它创建一个小的 CHM 并让视频文件保存在它旁边。
另一个程序htm2crm处理一个大文件(右)。但文件内部路径不正确(左)。
您知道如何创建包含内部视频的 CHM 文件吗？为了拥有一个大文件。
最佳答案
简短的回答是 - 我不知道目前有任何应用程序可以使用集成的 .mp4 视频。
经过几次当前的尝试，我只能确认 statement Tim Green 已于 2014 年制作:
.. CHM now only permits embedding of SWF video files. All other video file formats must be external to the CHM, otherwise they won't play.
请注意以下引用自 About using video files 的提示
Use online video services in CHM. Help+Manual handles this so that the online site is only accessed when the user actually clicks on the preview image to start the video.
Local video formats will always cause problems in CHM files for at least some of your users and should be avoided.
Since the termination of Flash support, Microsoft CHM files no longer support embedding for any video formats. MP4 video files can be embedded in Windows eWriter eBooks. All other video files must be distributed with your help as separate files.

对于特殊情况，我记得一些旧的东西将视频文件保留在帮助文件之外并使用脚本来引用它们。在帮助项目中包含大型视频文件可能会产生巨大的已编译帮助文件。有时您也可能需要更新这些文件。
