Yapo Video Player: understand a foreign language easily with your favorite movies and TV shows

The client had an idea. We worked through it, together with him we drafted the technical documentation for the project and helped in the selection of technologies:
As a player, ffmpeg was selected. It has been adapted to the conditions of use with the ability to switch subtitles in real time, and for fast rewind.
One of the problems was that downloading content was possible only through iTunes, which very much scared many users. We have developed the functionality of uploading video content to a device from a computer through a browser, which reduced the user’s preparation time by several times.
