Is it possible to combine audio and video in android?

Question

• Hi Can I add audio to a video in Android (Java).
• List item Both are on my SD card and are combined and transferred to mp4 format.

Answer 1

Yes, you can. But it will not be so simple, you need to find out about these api's

• MediaExtractor to extract data / track from file.
• MediaCodec if you want to encode / decode
• MediaMuxer to include it in mp4 file

You can use all three of them together if you need to or individually. You can find sample code here .
