Why doesn't music visualization work on Jelly Bean?

Postby MobileVisuals » Tue Aug 20, 2013 5:40 pm

Visualization for external players worked before, but it does not work on Jelly bean. I have played music with external players, like Spotify and Winamp, while debugging the apps. The bytes in the updateVisualizerFFT method are always 0 for external players, when a visualizer is created with 0 as an argument:
new Visualizer(0);

This results in no visualization, since there is no signal to use for visualization. Do you know why this happens and how this can be fixed?

It still works for internal players. I mean when the app has its own built in player. The bytes in the updateVisualizerFFT are not 0 then, so the app has something to use for visualization, even when the visualizer is created with 0 as an argument.

I see, where did you find information about this? I can not find any info on why visualization for external music player is not supported by Jelly bean.

So Morphyre Music Visualizer does not support external players? It says on their product info that it visualizes "whatever is playing on your Android device". It also says "Some music players apply filters to the music they play, and so do not allow visualizations to react to the sounds they produce".

Morphyre Music Visualizer has features for External player app control. Using Snoop mode or Live Wallpaper mode this app provides visualization for another media player as well.

You said that visualization for external music player is not supported by Jelly beans OS. In that case, how can Morphyre provide visualization for other media players with Snoop Mode?

If this is the case, does it mean that visualization for external music player is supported by Jelly beans OS?

If you have this kind of players you have to disable filters (if possible), You can set up Morphyre to use the Microphone for sound reactivity or simply use any other Music players available for Android.

I assume that "Microphone for sound reactivity" does not visualize the music from Spotify or Winamp, if it is played from headphones? I assume that it only visualizes the music when it is played from a loudspeaker?

What do you mean with "simply use any other Music players available for Android"? How can it be simple if I have to disable the filters for each one of them?

My company has developed some music visualizers. I want to fix this problem in my apps, so they can visualize music from other apps. Do you know if I can disable filters for Spotify in the code for my apps?

Or is this something, which the user has to do? I mean, does the user has to go to the Spotify app settings and disable the filters from there?

There is an intent filter for music files, you have to remove that filter from the Spotify Android app.

I assume that this is not something that I can do from the code in my own app? I assume that I have to go to the settings for the Spotify Android app to do that?
