Java implements PPT to MP4 file conversion

Environmental requirements

Must be a Windows computer with Microsoft Office installed and activated.

Import Jar

First introduce the jar package in the pom

<dependency>
  <groupId>cc.pptshow</groupId>
  <artifactId>pptshow</artifactId>
  <version>1.3</version>
</dependency>

write test code

This jar package has encapsulated this method and can be used directly

PPTUtil.PPT2MP4(String pptPath, String mp4Path)

The first parameter is the PPT file address

The second parameter is the path of the mp4 file that needs to be generated

Due to system reasons, parallel generation is currently not supported

Notice:

1. The system must have installed and activated Microsoft Office
2. Windows system only
3. During the generation process, there may be an abnormality in the Office software that may cause the conversion to fail, so be sure to test that your Office is not a lite version, only if you have this function!

 

compressed MP4

The generated video is generally relatively large (more than 100M), and generally we need to use it after compression

Compression requires that ffmeng has been installed on our computer and the environment variables have been configured

PPTUtil.mp4Compression(String bigMp4Path, String smallMp4Path)

bigMp4Path: MP4 file generated by PPT2MP4 method

smallMp4Path: The storage path of the reduced file, ending in .mp4, does not support overwriting, and there must be no file in this path

The MP4 file generated by compression is automatically compressed into a 1280x720 video with 15 frames. Generally, the 25-page PPT video is about 20MB after compression

Notice:

1. It is necessary to install ffmeng on the computer and add environment variables
2. Adjustment parameters are not currently supported

Tips

Support animation operations (both element animation and page change animation are supported)

Support Chinese fonts, no need to convert fonts in advance (provided that the fonts are installed on the computer)
