I'm not sure if this is the right place to ask. If not could you please tell me where to ask?

My company is searching for a replacement for VKC Media Player. Can you tell me if your app meets the following requirements?

Sixteen Cameras
We need to support displaying upto 16 cameras while keeping optimal performance

We use the option to take snapshots while displaying Audio selection in Live Streaming

Required for playing with live streaming and playback mode
RTSP and HLS Stream
Playing RTSP and HLS stream in Client and Live Streaming
Playing DVR Data
Playing for DVR data in Live Streaming, we should be able to jump back and forth with ease while watching

We also need accurate duration/time of the DVR data (which increases every X seconds while the live stream is ongoing)
Be able to start and stop playing the streams
Debug Logs
We have been relying on VLC logs for debugging issues from time to time
Custom Parameters

Thank you,
