What are the problems with miracast screen mirroring
Today, I will introduce you to some of the problems of miracast screen mirroring, such as our common image loss, black screen, blurred screen, delayed freeze, disconnection and other undesirable situations.
Miracast screen mirroring principle
Miracast uses the point-to-point Wi-FiDirect standard. It allows sending up to 1080p HD video (H.264 codec) and 5.1 surround sound (AAC and AC3 are optional codecs, the mandatory codec is linear pulse code modulation-16-bit 48kHz 2 channels). The connection is created via WPS, so WPA2 is used for protection. IPv4 is used at the Internet layer. At the transport layer, TCP or UDP is used. At the application layer, data transmission is initiated and controlled through RTSP and RTP.
Problems with miracast screen mirroring
Android phone manufacturers have not standardized the naming of MiracastSource. When users use it, they don’t know where to find this feature.
When using MiracastSINK, TV set-top boxes and smart TVs basically need to switch the WIFI mode, such as the need to cut off the WIFI link or hotspot mode, which increases the user’s learning and use costs.
At present, the access compatibility of MiracastSINK is relatively poor, which is manifested in: the phone cannot be connected/the phone connection time is very long, etc.
The stability of the existing MiracastSINK is relatively poor, as shown in: after multiple uses, the projection device is no longer connected/disconnected after a long time connection, etc.
The current experience of MiracastSINK needs to be optimized. The performance is: audio and video will be stuck or mosaic/picture is not clear/picture delay is relatively large.

How to solve the problem of miracast screen mirroring
If I say that it is impossible to solve the problem through the miracast screen mirroring protocol, and it does not make sense to users.
At present, no one can solve these problems.
Users only need to be able to stable, smooth and convenient wireless screen mirroring.
Therefore, AWIND adheres to the LINUX architecture and develops a wireless projector compatible with miracast screen mirroring, Airplay screen mirroring and DLNA screen mirroring to professionally solve wireless screen mirroring problems.
