gl-streaming

Streaming opengl commands over network

A fast, simple, lightweight and low latency framework suitable for embedded systems.

Original image

• gl_client : client framework and sample program

  The client system may not need to have any GPU. Even without GPU, opengl programs can be run on any system !

  (X Server is now required by client).

  Some codes are from @mittorn fork for base methods, @tinmaniac for base Android port and do my attempt on implement all stub methods to run on GL4ES.

• gl_server : server framework

  gl_server is optimized for Android for now. Therefore, the client system can use opengl es 2.0.

• android_gl_server : Android demo port app.

TODO implement

• glGetActiveUniform
• glGetError
• glGetIntegerv
• glGetFloatv
• glReadPixels (experimental)
• glGetProgramiv
• glGetShaderiv
• glGetString
• glTexSubImage2D

Current status

• es2_info, es2gears will work; es2tri probably.
• Some apps/games run on GL4ES will work on a blank screen, other will get crashed.

Notes

• Current minimum SDK level is set to 21 (Android 5) but it may work on older Android devices by some modify.
• Default port of server: 18145, client: 18146.

Known issue (Android)

• Rotate screen (change orientation) or put app to background cause app to spawn huge memory usage in a short time.

Quick start

Server

• Build android_gl_server use Android Studio or other similar to.
• Install android_gl_server apk to Android device or Emulator.
• Run it.

Client

• copy the gl_client directory to any computer.

cd gl_client

make

./sample1 -s 192.168.0.2:18145 -c 192.168.0.3:18146 -j /dev/input/js0

./sample2 -s 192.168.0.2:18145 -c 192.168.0.3:18146 -j /dev/input/js0

(Usage: ./sampleX [-c my_ip_address:port] [-s server_ip_address:port] [-j joystick_device])
