The i.MX27 (used on the APF27) has an internal DSP which can be used to encode/decode video stream, coming from various sources (CSI, buffer, etc...). To use it Freescale provides some useful tools.

Installation

$ make freescale-tools
  • then reflash your rootfs and you will get some stuff in /usr/bin/vpu/

Usage

mxc_vpu_test.out (yeah Freescale has strange ways to name its executables ;-) ) allows you to decode/encode video streams. This tool needs a configuration file (some are given as examples).

# mxc_vpu_test.out -c codec.cfg.net.enc.vga.h264
