Android Question Media Player - setDataSource (MediaDataSource dataSource)

[shashkiranr]

Hi All,

I need to play an audio file from a byte array. I came across where you can set the data source of media player to be of type MediaDataSource.

As per the android developer - "For supplying media data to the framework. Implement this if your app has special requirements for the way media data is obtained"

I am getting the audio from an external source through the B4J webserver in a custom encoded format. I can decode the stream and want to use the bytes to play the audio without creating a temp audio file.

Is there any way to create a MediaDataSource so that I can use it with Media Player.?

Kindly let me know.

I don't think that there is any library available that implements a memory based MediaDataSource.

Hi Erel,

Is it possible to create the datatype using Javaobject or reflection or Inline java?

If it's decoded to PCM format you can play it directly with the Audiotrack library. https://www.b4x.com/android/forum/threads/audiotrack.14007/

Hi Steve,

I have to custom seekbar for which I need to set the secondary progress of the audio file that I am playing and it is not easy to implement with audiotrack or I still have to figure out how to do it and modify it for my current implementation and I am looking into it.

@Erel Is there any possibility MediaDataSource will be added in the future for the library?

Best,
SK

If your passing data from an array, you already know the position and don't need either library to return it.
