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

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

Current status

• es2_info, es2gears and es2tri will work.
• GL4ES apps/games may work but in blank textures (will see in glxdemo and glxheads).

Notes

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

Known issue (Android)

• Some old devices: put app to background will make app lost EGL context (not show anything).

Quick start

• See USAGE.md for more instruction.

Server

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

Client

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])
