[NativeMediaPlayer] [BUG] Errors in data chunk when playing single item

[Manurocker95]

Playing a playlist with a single item throws this error:

AndroidJavaException: java.lang.OutOfMemoryError: Failed to allocate a 104 byte allocation with 1958456 free bytes and 1912KB until OOM, target footprint 268435456, growth limit 268435456; giving up on allocation because <1% of heap free after GC. java.lang.OutOfMemoryError: Failed to allocate a 104 byte allocation with 1958456 free bytes and 1912KB until OOM, target footprint 268435456, growth limit 268435456; giving up on allocation because <1% of heap free after GC. com.google.gson.reflect.TypeToken.(TypeToken.java:72) com.google.gson.reflect.TypeToken.get(TypeToken.java:303) com.google.gson.Gson.(Gson.java:114) com.glitch9.media2.playlist.Playlist.(Playlist.java:41) com.glitch9.media2.Media2.processData(Media2.java:137) com.glitch9.media2.Media2.$r8$lambda$2ciMAVAim7f76ihqAWdchtbEwgA(Unknown Source:0) com.glitch9.media2.Media2$$ExternalSyntheticLambda1.accept(Unknown Source:4) com.glitch9.media2.utils.DataReceiver.receiveDataChunk(DataReceiver.java:40) com.glitch9.media2.Media2.receiveDataChunk(Media2.java:117) com.unity3d.player.UnityPlayer.nativeRender(Native Method) com.unity3d.player.UnityPlayer.-$$Nest$mnativeRender(Unknown Source:0) com.unity3d.player.UnityPlayer$F$a.handleMessage(Unknown Source:122) android.os.Handler.dispatchMessage(Handler.java:102) android.os.Looper.loopOnce(Looper.java:210) android.os.Looper.loop(Looper.java:299) com.unity3d.player.UnityPlayer$F.run(Unknown Source:24) UnityEngine.AndroidJNISafe.CheckException () (at <00000000000000000000000000000000>:0) UnityEngine.AndroidJavaObject._Call (System.IntPtr methodID, System.Object[] args) (at <00000000000000000000000000000000>:0) Glitch9.NativePlugins.NativeMediaPlayer.MediaPlayer.HandleInitialization (System.Boolean playWhenReady, System.Int32 startMediaItemIndex, System.Single startPosition) (at <00000000000000000000000000000000>:0) Glitch9.NativePlugins.NativeMediaPlayer.MediaPlayer.Initialize (Glitch9.NativePlugins.NativeMediaPlayer.Playlist playlist, System.Nullable1[T] playWhenReady, System.Nullable1[T] startMediaItemIndex, System.Single startPosition) (at <00000000000000000000000000000000>:0)

2024-07-04 update

• changed the logic to send each media item + compression
• added artwork size limit (2mb)
• test successful on Pixel 6 (8gb ram), Galaxy note 8 (6gb ram)

will work on iOS if this works on Manurocker95's end.

Not working: That version is triggering this:

[Manurocker95]

Crashing on Retroid Pocket 4, Redmi Note 9 and Anbernic 405

[Manurocker95]

What trigger the error is:

 // java: public void receiveMediaItem(int mediaItemIndex, String json) 
 foreach ((int index, string json) mediaItemData in DataTransferUtil.SendMediaItems(CurrentPlaylist))
 {
     _plugin.Call(RECEIVE_MEDIA_ITEM, mediaItemData.index, mediaItemData.json);
 }

[Manurocker95]

Before crashing the following events are triggered:

ON_PLAYLIST_UPDATED ON_INIT_CHANGED_TRUE ON_IS_PLAYING_CHANGED_FALSE

This line is a big hint. I believe you are using PersistentDataPath but it's loading audio from StreamingAssets

[Glitch9Inc]

Yeah that was crucial. The new playlist factory was not passing the correct uriType. I'll send you the updated version with this fix.

Noice! I sent you by mail an example that crashes so you can check if that also works :)

[Manurocker95]

Playlist.AddMediaitem(mediaItem) overrides the mediaItem datapath in "prepareMediaItem" within "playlist DownloadDirectory":

    private MediaItem PrepareMediaItem(MediaItem item)
    {
        item.PlaylistIndex = Index;
        item.Index = index;
        item.PersistentDataPath = DownloadDirectory;

        if (item.UriType != UriType.Unknown && item.UriType != UriType)
        {
            Debug.LogWarning($"MediaItem#{item.Index} UriType is not equal to the Playlist's UriType. Setting it to the Playlist's UriType.");
        }

        item.UriType = UriType;
        return item;
    }

[Manurocker95]

In addition, mediaitem constructor should set PersistentDataPath value to URL in constructor when uritype is PersistentDatapath

[Manurocker95]

In addition, you now need to set the whole persistentdatapath value instead of the relative value so AFTER doing playlist.AddItem, u need to do

            playlist.MediaItems[playlist.MediaItems.Count-1].PersistentDataPath = Application.persistentDataPath + "/" + filePath

            or modify the value in the prepare

[Manurocker95]

MediaItem constructor should be something like:

    public MediaItem(UriType uriType, string url, MediaMetadata metadata = null)
    {
        this.uriType = uriType;
        this.url = url;
        this.metadata = metadata;

        if (uriType == UriType.PersistentDataPath)
        {
            this.persistentDataPath = Application.persistentDataPath + "/" + url;
        }
    }

and prepare item in Playlist:

    private MediaItem PrepareMediaItem(MediaItem item)
    {
        item.PlaylistIndex = Index;
        item.Index = index;
        if (string.IsNullOrEmpty(item.PersistentDataPath)
             item.PersistentDataPath = DownloadDirectory;

        if (item.UriType != UriType.Unknown && item.UriType != UriType)
        {
            Debug.LogWarning($"MediaItem#{item.Index} UriType is not equal to the Playlist's UriType. Setting it to the Playlist's UriType.");
        }

        item.UriType = UriType;
        return item;
    }

That makes it work on Editor but now on android is triggering:

Unity has received an error from Native: Error: 1, -2147483648

And I'm using the same exact audios which are .mp3. All of them worked before the data chunk rework.

[Manurocker95]

Okay, it seems the URL is skipped when "downloading":

2024/07/05 13:39:03.507 28847 28847 Warn System.err [NativeMediaPlayer] getPersistentDataPathAsset: /Audio/Albums/MySong.mp3

2024/07/05 13:39:03.508 28847 28847 Warn System.err [NativeMediaPlayer] File does not exist at /storage/emulated/0/Android/data/com.Manurocker95.MyProject/files/MySong.mp3. Downloading...

As you can see "Audio/Albums/" is completely skipped

[Manurocker95]

With latest update and manually sending Application.persistentDatapath + relativepath in persistentdatapath and URL, the audios play again.
