MediaCodec Mirroring

This is :

• Mirroring using MediaCodec.
• It operates in the background. So, it does not stop to interrupt.

※ interrupt ? call, message, home button and so on.

Server

• 1. get Bitmap using getDrawingCache().
• 2. Bitmap to Byte[]
• 3. Byte[] into Encoder
• 4. get Byte[] (encoded data) from Encoder
• 5. Transfer Byte[] to Client

Client

• 1. Receive data from Server
• 2. Received data to Byte[]
• 3. Byte[] into Decoder
• 4. Decoded data into Surface
• 5. Rendering with the Surface

However :

• It's not implemented layout.
• It's not encoded with the surface. So, need to RGB2YUV and NV21->NV12. Results in a low performance.

Feature

• Application Mirroring
• H.264 Encoding, Decoding
• It's not used MediaExtractor.

Requirements

• Requires minimum API 16 (Android 4.1)

Android API

• MediaCodec : http://developer.android.com/reference/android/media/MediaCodec.html
