How to add filters to a video in react-native? both on Android and iOS - react-native

I have added filters to recorded videos using react-native-camera while recording.
But now I have to add filters after recording.
If anyone has the solution pls let me know.
There is a separate solution for Android, but can't find a solution that works cross-platform using react-native. Maybe we need to use third party APIs or something like that.

Video Trimming In Expo

Am developing an app which a user can upload a video status just like whatsapp but I need a video trimming library which I can use to implement this feature where a user can trim some portion of the video they selected with a time frame. I searched and found some libraries like react-native-video-processing and others but none seems to work with expo. so I will appreciate if someone can give me a working one or a guide on how I can use ffmpeg or other libraries to archive this.

Is there a way to turn an app into a website in React Native?

I built an application in React, is there a way that the same code will be used for a website?
I know Instagram is built on React and it also has a website, I wonder maybe you should add some link or something that it will open for me as a website?
Or maybe there is no such way and I have to build a website separately?
First off all, If you have written any code which is related to native functionality, then it can be challenging.
If you have only worked with views, images, and some of the basic functionality.
It can be done with react-native-web you can easily migrate your project to react-native-web.
If you project is created with expo they already provide react-native-web support.
Option 2: If you have some of the code you want to share and some is that you don't want to share or can't share.
You can use renderProp or customHooks pattern to reuse your logical code and seperate your view for react-native and react js apps.
If you want to reuse your views too, you can do those with primitives.
you can use styled-component primitives for that.

You can get some idea here as well.

ListView section headers don't seem to be working on Android, but they work fine on iOS?

Has anyone had success with ListView section headers on Android? Using the documentation and a few handy tutorials I was able to build this for iOS:
When we run the code on Android (Lollipop and Marshmallow) the ListView just acts like a ScrollView...no section headers :(
Has anyone else run into issues with the ListView on Android? Were you able solve them? We're no against building a separate component for Android so if you know of another react-native component that can be used to achieve this effect that would be great too.

How can we achieve coverflow view in android titanium?

I have seen that titanium support CoverFlowView in titanium but it works only on ios, Can anyone have idea to achieve CoverFlow in android with titanium
Thanks in advance
Looks like you are in luck! Someone already built a coverflow module for Android using the Android development environment.
https://github.com/moondroid/CoverFlow
You need to be willing to write the additional code for that to turn it into a module for Titanium.

It should be possible, but I must admit I've never tried to write one myself.
Basically you cannot get Coverflow on Android. Since it is a native iOs component which is not implemented in Android at all. Frameworks like Titanium always "link" your commands to internal system APIs. When there is no API there is no way to access it. Of course you could try to build it on your own but I think this would not work that well. And its a lot of work!
Additionally cover flow is not really useful (except for holding just a few items). Have a look at my question at ux.stackexchange.
