Hello Albert,
How are you doing ?
I have read your job description, Now I am ready to work on FFMPEG in browser to edit short videos,and It will be mobile friend and works perfect on safari and other browser, with the flow will follows as;
1. The user imports a clip to our website.
2. The user uses our online video editor to select which areas to use and which images to add.
3. Once the user is done, a new page will be open, it will display the message "We are creating your clip".
4. Once this page is displayed, ffmpeg will run in browser. This is your part to be developed.
5. Once ffmpeg ends, a success message will be displayed and the user will be able to download the file.
