Example of inter-process texture sharing with DMA-BUF

An example of how to share a GL/GLES texture in EGL context between different processes by using DMA-BUF.

Detailed explanation is in this blog post.

Prerequisites:

• Linux OS (for dma-buf and unix domain sockets)
• EGL extensions:
  • EGL_MESA_image_dma_buf_export
  • EGL_EXT_image_dma_buf_import
• GLES extensions:
  • GL_OES_EGL_image_external

Build:

$ make

Run:

# Terminal 1
$ ./dmabufshare server

# Terminal 2
$ ./dmabufshare client
