App for video player for Android and iOS

We need a custom SDK for a video player / recorder for Android and iOS which:



Should support RTMP live streaming playback
Can set any size preview
Adaptive play back with any network [LTE, wifi]
Record playback on file system
Automatic network abnormal reconnection
Supported network protocol RTMP/RTMPT/RTMPE/HLS
Supports playback of incoming calls to keep the network stream, pause the playback, and resume playback after hanging up
Support simultaneous playback of multiple live streams (we need to put at least 6 players on one screen)
Support setting the maximum buffer duration to prevent delay accumulation
It should not Freeze the video like VLC, we have already tried many video players and those have problem of video freezing over network
Must have strong microphone noise reduction algorithm because this player is also working as a recorder
