How to merge two videos in android
4 juillet 2016, par LukasI’m new to android, but not new to mobile development.
My goal is to record two videos, and the mix it into one video using audio from both tracks. E.g two recorded videos are both 10 seconds. I want to take the first 5 seconds from the first video, and the last 5 seconds from the second video, combine them together with combined audio from both videos, and have it in an mp4 file.
On iOS there is an AVFoundation framework, which lets you combine multiple videos and audio into one video file (h.264 codec in mp4 container). I want to achieve similar results on android, but fail miserably at finding frameworks or 3rd party libs for doing that. If anyone could help me by showing some links or any directions where to look for information it would be really helpful. Thanks in advance !
