ScreenCastDemo

This is a FFmpeg 4.0 android library demo built over android MediaCodec Encoders(H.264, AAC).
You - as a developer - can easily cast android screen with this library to Network (RTSP, RTMP, UDP, ...) including File.

You can mirror your Android device screen to a PC or a SmartTV.
The RTP unicast is more stable than UDP unicast.

1) For RTP, ScreenCastDemo options can be :
    -f rtp -sdp_file /mnt/sdcard/rtp.sdp rtp://your_pc_ip:port
    ex) -f rtp -sdp_file /mnt/sdcard/rtp.sdp rtp://192.168.10.10:1234
Press START button, then after about 15-seconds later the screen cast will begin.
And the sdp_file - /mnt/sdcard/rtp.sdp - is generated in your Android device.
Take out the rtp.sdp file to your PC and remove the top line which contains 'SDP:'.
And play the rtp.sdp file with VLC player.
1-1) For RTP (2nd)
      -f rtp_mpegts rtp://your_pc_ip:port
      ex) -f rtp_mpegts rtp://192.168.10.10:1234
Press START button, then after about 15-seconds later the screen cast will begin.
And play VLC in your PC with rtp://@192.168.10.10:1234 or just rtp://@:1234.

2) For UDP, ScreenCastDemo options can be :
    -f mpegts udp://your_pc_ip:port?pkc_size=1316
    ex) -f mpegts udp://192.168.10.10:1234?pkt_size=1316
Press START button, then after about 15-seconds later the screen cast will begin.
And play VLC in your PC with udp://@192.168.10.10:1234 or just udp://@:1234.
