Which player to use (with API or SDK) for android with the ability to control the playback speed?

Question

Android

Good afternoon.
We want to embed the player in our application, but we can't find a suitable modem with the necessary functionality, namely, the ability to control the playback speed. Since the project is large, we are ready to buy a paid license.
In vitamio they do not answer, and in NexStreaming , judging by the demo, there is no speed control.
