How to create a video from an array of images in Android?

Question

I want to call a function and build a video out of list of images, and then save it locally on the device:

public void CreateAndSaveVideoFile(List

        

Answer 1

You can use Bitmp4 to convert sequence of images to MP4 file.

Sample code :

...

val encoder = MP4Encoder()
     encoder.setFrameDelay(50)
     encoder.setOutputFilePath(exportedFile.path)
     encoder.setOutputSize(width, width)

 startExport()

 stopExport()

 addFrame(bitmap) //called intervally

It's a java library so it's easy to import it into Android project, you don't have to use NDK unlike ffmpeg.

Refer https://github.com/dbof10/Bitmp4 for sample code & downloads.
