Concatenate video & audio in react native

Request details

Hi, we’re building this mobile app in react native for iOS currently: [login to view URL]

It’s nearly ready but I can’t find a dev who knows how to concatenate video and audio files together in react native.

What we have so far: there is a studio in the app where you can import audio and video files. Then you can change the time positions of the video files inside the video track, and you can do the same with audio files in their audio tracks. There can be many audio tracks with one or more audio files inside them. Then you can apply audio effects to the track and change the track volume. For audio we are using the Superpowered SDK; you’ll need to use this SDK to save the applied effects and volume to the audio file. Users can also split audio files at whatever time position they choose and delete a split off portion.

So what I need is:

You need to make it so the user can export concatenated video and audio tracks and save the resulting file(s) to their iCloud (and camera roll for video).

For the audio track, all audio effects and volume chosen by the user should be applied to the saved file.

User should be able to choose: export all, export track, export video, export audio.

—export all: export all tracks in the studio as separate files and save them in a zip file to user’s iCloud. Each track must have all files within the track concatenated and with correct time positions and audio effects/volume applied.

—export track: export just the currently selected track (concatenate together all files inside the track, with audio effects/volume applied) and let the user save it to their iCloud (and camera roll for video track).

—export video: create a video by concatenating all video and audio files in the studio, with their correct time positions and audio effects/volume, and let the user save it to their camera roll and iCloud.

—export audio: create an audio file by concatenating all audio files in the studio, with their correct time positions and audio effects/volume, and let the user save it to their iCloud.

Please let me know your time and cost estimate to complete this task. Thanks.
