1 MANISHA AGRAWAL: Hi. My name is Manisha Agrawal. I am with Texas Instruments Video Security team. In this video, I will be covering DM385 IPNC RDK out of box demo-- Part 3. Here, I'll be showing flashing the uboot using prebuilt binaries available in RDK-- running IPNC using NFS filesystem-- runtime configuring the camera and video parameters using Web browser on Internet Explorer-- playing the IPNC streamed video on VLC player. And finally, I will also show how to boot the camera from SD card. For this, you will need a Linux machine with Ubuntu or above, a Windows machine-- XP or 7-- and DM385 IP network camera. Let's begin flashing the nand using the prebuilt binaries available in RDK. Here the assumption is that your camera is already flashed with some version of first stage and second stage uboot. And hence, you are able to see the second stage uboot prong after you hit Enter-- seeing this DM385 on your Teleterm console. To flash the camera from the prebuilt binaries, you need to come to your Linux machine under directory binaries of the installed RDK package. Go to the directory, DM385 nand. Under that, you will see two for the directories, depending on the camera type that you have. Go to the directory AR331 if you have a [INAUDIBLE] camera.

2 If you have Panasonic sensor camera, then go to the directory MN Copy these binaries to your TFTP server location. Now, instructions to flash the nand from uboot is handy in this file update dot txt, available under folder binaries. Simply copy/paste those instructions from update dot txt to the Teleterm console running on the Windows machine for updating the first stage, second stage uboot, kernel, and updating the file system. Now, if the TFTP server IP address is not updated in your camera, you need to update the IP address of the TFTP server by typing this command-- see if there's enrollment [INAUDIBLE]. Type dhcp to get the IP address to camera. Now copy from the update dot txt one instruction at a time. And paste it on your Teleterm console. With this, you are done updating your first stage, second stage uboot, kernel, and file system on a working camera using prebuilt binary. Now you need to update the bootargs and boot commands. Again, you can copy that from update dot txt. For low power boot command for Panasonic sensor, just copy these instructions. And paste it to your Teleterm console. For UBIFS spaced bootargs and dhcp boot mode, copy this instruction. Now, I will cycle the camera. Now with this, camera is updated with the latest binaries and running same without any issues. Now, since camera is up and running, let's see how to access the streams from the Internet Explorer and runtime configures various parameters of the camera.

3 For this, first get the IP address of the camera. To note the IP address, type ifcon fig. And it will print the IP address of the camera. Copy this. Open the IP Explorer. Type the IP address of the camera I show on my screen. It will ask you if you would like to install the software. Press Install. After installation, you will see the main login screen. Enter the username as admin-- a-- d-- m i n. Password is four times-- 9 and submit. Now you can change video's parameters of the camera runtime from here. Left Panel allows you to navigate to the other screen. I will go through a few menu options here. You can read IPNC RDK GUI guide dot PDF to understand in detail various options and features to configure camera runtime. For example, in video settings, you can select the Stream Type if you want to run single streaming tools-- streaming or tri-streaming. By default, it is tri-streaming. You can select the Codec Combo that you want the streams to be--

4 of type. So, default type is primary stream is of type H dot 264. Secondary stream is also of type H dot 264. And third stream is of type MJ PEG. In this option resolution, you can change the resolution of various streams. Currently, only 1080p D1 as primary and secondary stream is supported. And third stream is always of type MJ PEG 1080p. You can select the Frame Rate options for individual streams here separately. So, the default's frame rate is 30 FPS at 10 megabits per second. And rate control is of type variable bit rate. You can change it to 60 FPS for the primary stream. Similarly, you can configure the Frame Rate, Bit Rate, or Rate Control for the secondary stream and for third stream. Go to the Advanced Feature. You can configure a face detection on or off. You can change the Region of Interest settings-- change the Confidence Level, and Direction. Face recognition is not supported on DM385. So you can ignore the settings. Say Configure. You can also turn on motion detection feature by pressing OK. You can change video's advanced feature of camera runtime. Like the two-way settings, you can turn off or on or to Exposure or to White Balance. Similarly, there are other options that you can set runtime. All these settings that you see here get stored in nand partition 5 of IPNC camera.

5 So, next time when you power cycle the camera, it runs from those settings that you configured last time from the Web browser. So, if you want to reset the settings, you need to type flash underscore erase all dev mtd5 on your Teleterm console after you log in as root. Let's now look at playback of these streams streaming from the IP network camera on VLC player. For this, you will need to download the VLC player. To download this player, go to www dot videolan dot org. Click on Download VLC. And this will download the VLC player on your Windows machine. Double click on the downloaded executable. This will open up a window. Click on Run. To open the stream, go to Media. Open network stream. And copy this link to play H dot 264 first stream on VLC player. And paste it over here. This will start playing the streams on VLC player. The link to be copied on VLC player is also documented in Section 3.4 RTSP streaming demo in VLC section of RDK install guide. So you can copy this one your VLC player after replacing this with the IP address of the camera. And you know how to get the IP address of the camera. For that, just go to your Teleterm console.

6 Press Enter. And then type ifcon fig. Just use this. And replace it to over here. And finally, copy this link to play the first stream on your player. Copy this link to play this H dot 264 secondary stream on your player, and so on. You can also change fields in media player settings for low latency playback, as I mentioned in Section of IPNC RDK install guide. Note that the settings are documented for version 2 dot 0 dot 3 of VLC player and hence may not be applicable to the later versions of VLC player if you have downloaded [INAUDIBLE]. So far, you learned how to run out-of-box demo with UPIFS filesystem. Now, if you are needing to modify some software or adding some feature to RDK and want to incrementally run or test a feature, you may want to run IPNC with NFS-based filesystem. With that, you need to have NFS server installed in your Linux [INAUDIBLE]. How to install NFS server on Ubuntu Linux host machine is documented in Section of IPNC RDK install guide. Just copy this instruction on your Linux host machine. And this will install the NFS server on your machine. For my machine, you are seeing the instruction that this is already the newest version, as I already have NFS server installed on my machine. Next, you need to do is to export the target file system path in the next host machine where the file system is mounted.

7 For that, refer to Section of IPNC RDK install guide. Refer to Step 3. So, you need to open etc exports file as root. And copy/paste this in that file. After modifying the path, export the backup filesys installed in your Linux machine. So, I have updated etc exports file with path of the filesys in my Linux host machine. Do the changes. Save the file. And close it. After that, export the file system by running this instruction s root on your Linux host machine. Once exported the file system, start NFS service using this command-- s root. With this, the NFS server is turning on Linux machine. And now you can access the files running on Linux machine from your IPNC camera after modifying the bootargs as documented in IPNC RDK install guide. For that, refer to section 3.1 of IPNC RDK install guide. And go to the section of bootarg settings. Copy these bootargs in your Teleterm console after second stage uboot prompt. After modifying this NFS root path, export the path in your Linux host machine. Here, you need to update the address with your NFS server IP address and the location of your target file system running on Linux host machine. Modify the eth address. Export the MAC address of your IPNC camera.

8 And modify IP equals to-- with DHCP if you're running in a DHCP mode. If you are running in a static IP mode, you need not modify this address. I copied the bootargs from the RDK install guide to note that and updated NFS root with the location of my machine. I also updated the eth address and the IP as per my settings. Now copy/paste that to your Teleterm console after second stage uboot prompt. And then type Boot. With this, your camera is now running with binaries on the filesystem on your Linux host machine. Finally, I will show how to boot from SD card. For that, you need a SD card with 1GB or above size. A flash card reader/writer that can be plugged on your Linux host machine. To format SD card, you will need first stage uboot, which is MLO. Second stage uboot binary, kernel binary-- and the tar vol for file system. I am showing here the prebuilt binaries of a [INAUDIBLE] RDK package for Panasonic sensor. So, you have separate tar vol for full feature or the low power application. To create tar vol of your own file system, make sure you are at the level target filesys. At this level, type sudo, tar, cvfz-- name of the tar vol that you want to give. And create two [INAUDIBLE] folders under this directory. So, that is dot forward slash star.

9 Press Enter. This will create the tar vol of the file system under that directory. Now copy it to the location where all other binaries for the SD card are located. Plug the SD card reader to your Linux machine. Take where the card mounted. For that, you can see ls, dev, sd, star. So, I see on my machine it is mounted to SDB. So, first thing is to unmount these partitions. Once you have unmounted those partitions, if any existed on your SD card, you need to format the SD card. There is a script-- mskd-ti814x.sh-- available under location I RDK utils sd script. Copy that script to the folder where all other binaries are. Now type this command-- sudo-- name of the script-- name [INAUDIBLE] for this device-- first stage uboot-- then name of the second stage uboot binary-- [INAUDIBLE] image-- and finally, name of the filesys tar vol. Press Enter. It will ask to continue or not.

10 Make sure that you are giving the right device name. If you accidentally give the name of your Linux machine, then it will format your entire Linux machine. So, be very sure that you are giving the device name for the card. To ensure the name of the device, I do a list dev sd star before plugging in the flashcard reader/writer. So, before plugging, it just shows me dev sda. After plugging the sd card reader/writer when I do ls slash dev slash sd star, I do see additionally the SDB. This confirms that the card reader/writer will not take the name-- the SDB. With this, it has completed formatting of the SD card. To run the camera from SD card, take the [INAUDIBLE] port and short the JP two pins as shown on my screen. Next, insert the SD card in IPNC camera as shown on my screen. [INAUDIBLE] the connection remains seen as shown in the hardware setup Section of RDK out-of-box demo video Part 2. Now, to run the camera from SD card, you need to update the boot command in bootargs. For that, go to the RDK install guide. And refer to Section To boot from SD card, the boot command should have this instructions. Now, there is a bug in IPNC RDK install guide of version 3.2. For Panasonic sensor boot command for SD boot, here this MMC rescan scan 0 fatload mmc 0 is not updated. So what you need to do is to just replace this part of the Panasonic sensor boot command with the highlighted portion of the boot command for ft [INAUDIBLE]

11 sensor. This is how the boot command for Panasonic sensor should look finally. Copy this. And paste in your Teleterm console. After that, copy those bootargs to your Teleterm console after updating the eth address with your EMAC address off the IPNC camera and the IP [INAUDIBLE]. Paste to your Teleterm console. And enter boot. With this, the camera is now booting from SD card. This concludes Part 3 of out-of-box demo. Thank you for watching this video.
