  • RPI Xorg driver
  • Simon's accelerated X development thread
  • Rob Clark's xf86-video-omap
• Raspberry Pi Userland - recently released user space interfaces to binary firmware blobs to GPU and other hardware. See the announcement.

• Splash images
  • psplash - recommended by Mentor Graphics
    • As used with BeagleBoard and BeagleBone
  • Plymouth - early userpace splash, replaces usplash, xsplash, splashy and bootsplash
  • xsplash - X based boot splash
  • usplash - Userspace bootsplash utility
  • Splashy - userspace replacement for bootsplash in kernel

    • fbida releases
  • Configuring boot splash screens for OpenMoko - generally useful tips for u-boot and beyond.

Audio

• Driver: snd_bcm2835
  • If you want sound through the HDMI cable type: sudo amixer cset numid=3 2
  • if you want sound through the analogue (headphone) socket type: sudo amixer cset numid=3 1
• Amplify your music with MagicPlay and the Raspberry Pi

i2c / SPI

• Raspbian package: i2c-tools
  • Modules: i2c-bcm2708, i2c-dev
  • On Raspbian, need to add "pi" user to i2c group
    • usermod –a –G i2c pi
• SPI
  • SPI-based touch screens - discussion on getting these working on a RPi.

Distros

• Arch Linux

XBMC

• Raspbmc XBMC Build instructions provide assitance on how to build XBMC for that platform. Chances are that it will work for PiBox as long as dependencies are met. It appears that the userland utilities and libraries may be required for this.
• XBMC Raspberry Pi FAQ
• Cross-compilation of XBMC-RBP on Arch linux ARM
• Build problems
  • building Xbmc problems - suggests building Mesa as is, without EGL, as possible closure of build process for XBMC.
  • Problem with cross-compiling XBMC

Flash

• Shumway Project @ Mozilla; open SWF runtime, GIT Repo

• RPi webcam streaming - someone's experiments to get webcam streaming working on a Pi.
• How to play live video from USB Webcam on web page - discusses use of ffpmep/ffserver
• Streaming Raspberry Pi Camera H264 into HTML over RTMP - uses jwplayer and suggests only 1s delay
  • How to capture Webcam input with ffmpeg
  • crtmpserver (aka rtmpd) - can stream rtsp from ffmpeg input to JWPlayer
• GStreamer based
  • Web Cam streaming from Raspberry Pi to Android using gstreamer - includes an Android app for viewing the streamed output.
