This is a set of GStreamer 1.0 plugins for plugins for Freescale's i.MX platform, with emphasis on video en/decoding using the i.MX VPU engine.

Currently, this software has been tested only with the i.MX6 SoC family.

The software as a whole is currently in beta stage.

These plugins are licensed under the LGPL v2.

• imxvpudec : video decoder plugin
• imxvpuenc_h263 : h.263 encoder
• imxvpuenc_h264 : h.264 baseline profile Annex.B encoder
• imxvpuenc_mpeg4 : MPEG-4 encoder
• imxvpuenc_mjpeg : Motion JPEG encoder
• imxipusink : video sink using the IPU to output to Framebuffer (may not work well if X11 or Wayland are running)
• imxipuvideotransform : video transform element using the IPU, capable of scaling, deinterlacing, rotating (in 90 degree steps), flipping frames, and converting between color spaces
• imxeglvivsink : custom OpenGL ES 2.x based video sink; using the Vivante direct textures, which allow for smooth playback
• imxv4l2src : customized Video4Linux source with i.MX specific tweaks

You'll need a GStreamer 1.2 installation, and Freescale's VPU wrapper library (at least version 1.0.45).

Au-Zone has replaced the original WAF build system with a standard CMake build system to allow Debian packaging as WAF has numerous issues which make it unsupported by Debian.

KERNEL_HEADERS defines the path to the Linux kernel headers (where linux/ipu.h can be found). It is currently unfortunately necessary to set this path if linux/ipu.h is not in the root filesystem's include directory already. (Not to be confused with the ipu.h from the imx-lib.) Without this path, the header is not found, and elements using the IPU will not be built. By default CMake will attempt to find linux/ipu.h using /usr/src/linux-headers-uname -r/include as a HINT.
