VideoPlanet | I try to create video streaming application with Exoplayer | Video Player library

it wasn't the size after all I tested on some srt files that have a blank space for some duration and the flutter converter do a check on every element if the length is<3 it break on get out of the loop

I solved the issue by removing this line from my app level build.gradle file - implementation 'com.google.android.exoplayer:exoplayer:2.16.1'. I think there is no problem with the video player package, the problem is with the exoplayer.

As couldn't able to find direct player. I used cv module and ffpyplayer to integrate with pyqt5. it is temporarily resolved my issue. the code is given below.

The problem that I had was a high bandwidth in my flutter /firebase application . I had like 19gb a day with 10-20 videos and like up to 10 users.

There are two layers where caching can with this problem: initial video download, and subsequent video replay.

For initial video download, one option is to dedicate a server to act as an intermediary cache. It would download and stay in sync with the current videourl's content and then serve it. The videourls would then be pointed to this server so the client pulls videos from it.
This only moves the problem around though, and bandwidth isn't free. But you don't have to host this cache server, there are companies that will host for a fee.

The way caching can help for subsequent video replay is by keeping it in local temporary storage on the video playing client, and when returning to the video, retrieving it from local temporary storage and playing it - thereby avoiding asking it from the server again.

One possibly quick solution could be by using the better_player library. It allows many configurations, including using a cache. You can find it here

use event seeked and trigger it the first time setting the video.currentTime to 0, after that in the event you can continue to set at the end of the operation a new current time. After all remove the event and set the currentTime to 0 to reset the video.

This should work, but if I'm not mistaken you need to make sure the video has been prepared (essentially fully loaded) in order to change the playback speed, take a look at the official Unity documentation for the Video Player here

This is a known bug, which is a regression bug introduced in JavaFX 14. It was resolved in JavaFX 17. The best fix is to change your JavaFX version to 17 (or later; 17 is the current version at the time of writing). If that is not possible for some reason, reverting to version 13 or earlier will work, though you will see longer wait times before the video is ready.

In the pom, change to

Check out this question here: Firebase Storage Video Streaming

To achieve exactly what you're looking for you would have to upload your video in many different chunks and download them one by one.

And according to this answer on that post you can start streaming before the video is fully loaded, but it will still attempt to download the entire file.

While it is possible to achieve what you're trying to do with Firebase, this isn't really what cloud storage is meant for. If you want to achieve YouTube style loading as you go you should look into a dedicated video streaming service such as ziggeo

Another option, depending on your needs, would be to upload your videos to YouTube and stream them directly from your app.

Wrap your list of videos with a NotificationListener and listen to whether the user has started or stopped scrolling. Use this value to either play or pause your video.

Edit: misread your question. This will work for pausing once the user scrolls. If you want to detect whether the video is within the current view, check out ScrollablePositionedList.
