Hii,

Only .mp4 videos can be downloaded in the app. There is no feature to download YouTube videos or videos in other formats.

Thank you!

Mr. Priyank

I will wait for the solution. Thank you very much. This is important to me. Once these problems are solved, I will start working.

With each problem there is a video to make it easier for you to access the problem and solve it. Thank you very much and I am waiting for the solution

The first problem is turning on subtitles on all videos, and the subtitles do not separate. If you exit the video and come back again, the subtitles are working.

The second problem is that subtitles only works in landscape mode and does not work in full screen

The fourth problem with videos that work and videos that do not work together is that they have the same permissions, meaning that anyone with the link can watch it.

This works

These are from my server and the links are all there is no problem on the server, but in the application one works and the other does not.
The fifth problem is that comments and likes do not work and do not appear in the application
