Audio track name is not populated

[dawidchyrzynski]

Describe the issue Audio tracks returned by the MediaPlayer.AudioTracks.GetAudioTracks() have empty name regardless of the metadata. It applies to both MediaPlayer and ExoPlayer.

Your Setup (please complete the following information):

• Unity version: 2020.3.29f1
• AVPro Video version: 2.5.7 ultra
• Operating system version: Android 8.1
• Device model: Pico G2
• Video specs (resolution, frame-rate, codec, file size): H264, 3840x3840, 4 audio tracks (mp3)

To Reproduce

1. Open video file that contains multiple audio streams. Each audio stream should have title and language set
2. Call MediaPlayer.AudioTracks.GetAudioTracks() method. It returns proper amount of audio tracks but name property of each is empty.

Does it work in the editor?

[dawidchyrzynski]

The editor (macOS Monterey) shows the list of tracks but the title is missing.

Here is the metadata of the mp4 file:

VLC and MediaInfo apps are listing audio tracks properly with the title and language.

I have also noticed that "AudioTrack.Language" property is also empty on Android. See screenshots below. The first one shows C# implementation (printing audio tracks), the second shows the result. The code is executed in the main thread.

OK, thank you for the clarification. Our Android dev is back from holiday next week, so we will look into it further then.
