OpenVideo | 视频APP--数据源自优酷

First off, your modal and trailerbox are not defined correctly. They are offspring of a sibling of the button so .closest() will not find them.

For each element in the set, get the first element that matches the selector by testing the element itself and traversing up through its ancestors in the DOM tree.

It tests itself, then the parent, so it will not encounter those elements. You need to use .find() from the parent.

After some trial and error I figured out how to make this work in Angular 12. For those who are interested in getting a list of files in their Firebase storage repository and then populating an array so that you can display the filename and the download link in your Angular component the code I used is found below. I'll be the first to admit I'm not the greatest coder in the world though so use at your own risk!

I've tried it myself and you essentially need to install @mux/videojs-kit and to provide your env variable as suggested in the docs.

Here is how it looks like

Here is a start

You need to set for settings like this or in plist.

You should add a contentView on your activity onCreate So change your onCreate Like this:

I think the problem is that you are creating mutiple instances of MediaPlayer which is causing OutOfMemoryError exception. Also, do not forget to release MediaPlayer instance when you are done with playback. According to MediaPlayer Documentation:

It is also recommended that once a MediaPlayer object is no longer being used, call release() immediately so that resources used by the internal player engine associated with the MediaPlayer object can be released immediately. Resource may include singleton resources such as hardware acceleration components and failure to call release() may cause subsequent instances of MediaPlayer objects to fallback to software implementations or fail altogether. Once the MediaPlayer object is in the End state, it can no longer be used and there is no way to bring it back to any other state.

Add a method in MediaItemPlayer to release MediaPlayer after use:

I didn't understand what was the problem.But it was solved when I changed onActivityResult to

think that I saved the uri in database as a string

You no longer have rights to access the content.

How to solve this issue ?

Use ACTION_OPEN_DOCUMENT to let the user choose the content. Then, in onActivityResult(), call takePersistableUriPermission() on a ContentResolver, to have access to that content for a longer period of time. See this blog post and the documentation for more.
