SDK development for video player for Android and iOS

Here is the specification of video player SDK we need.

We need SDK of a video player for Android and iOS which can :

1. Should support RTMP live streaming playback
2. Can set any size preview
3. Adaptive play back with any network [LTE, wifi]
4. Record playback on file system
5. Automatic network abnormal reconnection
6. Supported network protocol RTMP/RTMPT/RTMPE/HLS
7. Supports playback of incoming calls to keep the network stream, pause the playback, and resume playback after hanging up
8. Support simultaneous playback of multiple live streams (because we will need to put 6 players on one screen)
9. Support setting the maximum buffer duration to prevent delay accumulation
10. It should not Freeze the video like VLC, we have already tried many video players and those have problem of video freezing over network
11. Microphone noise reduction
12. We are using FFMPEG so don't use that, otherwise it will conflict with our commands.
