I am streaming RTSP link and I am using the following class that is working. I have taken the main idea of this class from an official git repository:
https://code.videolan.org/videolan/libv ... ivity.java
Now, I have to add a feature. Pressing a button I would be able to record the streaming while I am watching this and save the file to disk. How can I achieve this?
