Linux development environments vary, so we recommend the following for ease of use and consistency when working together. The next few steps will assist you in the setup & configuration of your Linux host based on the physical setup shown below. 1. Configure a Linux Host - If you already have a Linux host machine, go to Step 2. If you do not have a Linux host machine, you can configure a Linux host machine on your Windows PC using a virtual machine. • Build a Ubuntu 10.04 LTS Linux host with VMware on WinXP (preferred) • Build a Ubuntu 10.04 LTS Linux host with VirtualBox on WinXP For standard EVMs: 2. Configure your development For Beaglebone: 2. Configure your development environment environment 3. Install the SDK - Within your Linux host machine, Install 3. Run the START_HERE Script - When Beaglebone boots, a START_HERE the Sitara SDK directory will display on your Linux host desktop. To start your evalaution and development using the BeagleBone, Run the START_HERE.sh script NOTE: The START_HERE.sh script will run the setup.sh script. For Beaglebone boards before rev A5 the setup.sh script will attempt to install a udev rule to load the ftdi_sio module with the proper parameters to recognize the Beaglebone. If you experience difficulty with the Beaglebone being recognized you can load the module manually by doing: • sudo rmmod ftdi_sio • sudo modprobe ftdi_sio vendor=0x0403 product=0xa6d0 4. Run the Setup Script - Once the SDK has been installed, NOTE: If using a VMWare image you will likely need to import the beaglebone Run the Setup.sh Script to guide you through the remaining into the VMWare image as a mass storage device using the instructions here development environment configuration. Configuring a Serial Connection If you chose not to use the setup.sh script (or START_HERE.sh) to configure you connection you can always perform the following steps to configure a serial connection with the board. • The following steps will help you validate that you have a valid serial connection with your target board IMPORTANT These steps are written for boards like the EVM-SK and Beaglebone which use an FTDI USB-to-Serial adapter. For boards with a straight UART connection you can ignore the steps for /dev/ttyUSBx and instead just use the serial port on your Linux host that is connected to the board • Connect the USB cable between your Linux host and your target board Sitara Linux Software Developer’s Guide 4 IMPORTANT On the AM335x EVM-SK, the USB cable enables a USB-to-serial interface to the Linux host PC. If using a virtual machine, please insure the AM335x EVM-SK is a selected USB device. NOTE If you are running your VMWare image with Windows 7 some USB-to-Serial adapters do not properly work with Windows 7. Make sure that your adapter specifically says that it supports Windows 7. You may also need to install an additional driver for your adapter. • Open a terminal and run the following command to find the USB serial adapters available on the system. The FTDI chip used on the board presents two serial interfaces to the Linux host. The first interface is the JTAG interface and the second one is the serial console interface. ls /dev/ttyUSB* You should see output like: /dev/ttyUSB0 /dev/ttyUSB1 NOTE If using VMWare you may need to pass the "Future Technology Devices" device into the VMWare image • As mentioned above since the board's serial interface is the second interface you will want to open a serial console to the second device node. In this case that is /dev/ttyUSB1. This can be done by doing: • minicom -w -s • Select Serial port setup and press ENTER • Press A to modify the Serial Device and change the device to /dev/ttyUSB1. Press ENTER • Press ENTER to exit the serial setup • Select Exit and press ENTER • You should now see a minicom window. • Power on the board, you should see "ccccc" being printed in the window, if so the serial connection is working as expected. Go ahead and leave this console RUNNING in the background. NOTE For the EVM-SK board the power button is under the board in the upper-right hand corner. You must press and hold this button to power on the board. NOTE For the Beaglebone the board will power on as soon as the USB cable is connected. you can reset the board by pressing the reset button which should provide you with the expected output Sitara Linux Software Developer’s Guide 5 SDK Directory Structure Overview The Sitara Linux SDK contains the following top-level directories and files These directories contain the code and tools used to develop for Sitara devices. • bin - Contains the helper scripts for configuring the host system and target device. Most of these scripts are used by the setup.sh script. • board-support - Contains the SDK components that need to be modified when porting to a custom platform. This includes the kernel and boot loaders as well as any out of tree drivers. • docs - Contains various SDK documentation such as the software manifest and additional user's guide. This is also the location where you can find the training directory with the device training materials. • example-applications - Contains the sources for the TI provided example applications seen during the out-of-box demonstration. • filesystem - Contains the reference file systems.

    (A/V Codecs) REDCODE RAW (.R3D) ARRIRAW

    What is a Codec? Codec is a portmanteau of either "Compressor-Decompressor" or "Coder-Decoder," which describes a device or program capable of performing transformations on a data stream or signal. Codecs encode a stream or signal for transmission, storage or encryption and decode it for viewing or editing. Codecs are often used in videoconferencing and streaming media solutions. A video codec converts analog video signals from a video camera into digital signals for transmission. It then converts the digital signals back to analog for display. An audio codec converts analog audio signals from a microphone into digital signals for transmission. It then converts the digital signals back to analog for playing. The raw encoded form of audio and video data is often called essence, to distinguish it from the metadata information that together make up the information content of the stream and any "wrapper" data that is then added to aid access to or improve the robustness of the stream. Most codecs are lossy, in order to get a reasonably small file size. There are lossless codecs as well, but for most purposes the almost imperceptible increase in quality is not worth the considerable increase in data size. The main exception is if the data will undergo more processing in the future, in which case the repeated lossy encoding would damage the eventual quality too much. Many multimedia data streams need to contain both audio and video data, and often some form of metadata that permits synchronization of the audio and video. Each of these three streams may be handled by different programs, processes, or hardware; but for the multimedia data stream to be useful in stored or transmitted form, they must be encapsulated together in a container format.

    Performance Testing Suricata The Effect of Configuration Variables On Offline Suricata Performance A Project Completed for CS 6266 Under Jonathon T. Giffin, Assistant Professor, Georgia Institute of Technology by Winston H Messer Project Advisor: Matt Jonkman, President, Open Information Security Foundation December 2011 Messer ii Abstract The Suricata IDS/IPS engine, a viable alternative to Snort, has a multitude of potential configurations. A simplified automated testing system was devised for the purpose of performance testing Suricata in an offline environment. Of the available configuration variables, seventeen were analyzed independently by testing in fifty-six configurations. Of these, three variables were found to have a statistically significant effect on performance: Detect Engine Profile, Multi Pattern Algorithm, and CPU affinity. Acknowledgements In writing the final report on this endeavor, I would like to start by thanking four people who made this project possible: Matt Jonkman, President, Open Information Security Foundation: For allowing me the opportunity to carry out this project under his supervision. Victor Julien, Lead Programmer, Open Information Security Foundation and Anne-Fleur Koolstra, Documentation Specialist, Open Information Security Foundation: For their willingness to share their wisdom and experience of Suricata via email for the past four months. John M. Weathersby, Jr., Executive Director, Open Source Software Institute: For allowing me the use of Institute equipment for the creation of a suitable testing

Why is the Specification and Best Practices document needed? At the request of their customers, content providers and post‐house have been creating mezzanine files unique to each of their retail partners. This causes unnecessary costs in the supply chain and constrains the flow of new content. There is a demand to make more content available for digital distribution more quickly. Sales are lost if content isn’t available to be merchandised. Today’s ecosystem is too manual. Standardization will facilitate automation, reducing costs and increasing speed. Quality control issues slow down today’s processes. Creating one standard mezzanine file instead of many files for the same content should reduce the quantity of errors. And, when an error does occur and is caught by a single customer, it can be corrected for all retailers/distributors. Mezzanine File Working Group Participants in the Mezzanine File Working Group were: Amazon – Ben Waggoner, Ryan Wernet Dish – Timothy Loveridge Google – Bill Kotzman, Doug Stallard Microsoft – Andy Rosen Netflix – Steven Kang , Nick Levin, Chris Fetner Redbox Instant – Joe Ambeault Rovi
