Capture mobile video stream data in Android.

Currently, there are two methods to capture mobile video data in real time. One is to obtain the source data through the camera callback. The source data obtained here is not encoded.

Some people send YUV data and draw pictures there, which also means video chat is really ridiculous. This method implements video chat, but the encoding library needs to be transplanted.

Currently, Android opencore code can be transplanted. For more information, see http://www.shouyanwang.org/thread-184-1-1.html.

FFmpeg encoding, which is hard to find on the Internet, but is also implemented by some people. (High encoding efficiency, but not support HD videos)

After the encoding is complete, the RTP protocol can be used for sending. Video. Let's not talk about the RTP protocol.

For the code of the above method, it is better to reply to the code at this link, which is not complete. Link: http://www.eoeandroid.com/thread-51460-1-1.html

2nd methods, that is, the method I used.

Recording through mediarecorder. Then, bind a localsocket to obtain the encoded video data transmission;

The Code is as follows:
