How to play audio while recording video and mix both audio and video after completion of record in Android studio
2 mai 2018, par TirupatiraoI tried ffmpeg and mediamuxer and some others solutions
But I’m unable to achieve it
I need feature like dubsmash
I tried some stack overflow answers even though not done
I want play audio while recording video and after that output will be the custom audio(what I have played) with video
Please help us...we are trying since 26 days onwards
Thanks
