• Format your newly created partition with ext3 file system

• Create a folder for mounting your new partition at /ext_hdd
• Mount your newly created hard disk partition to /ext_hdd

STEP 5: Copy a Single Program Transport stream to your file system to be used for emulator video playback.

• Pre-requisite to the step is assumed that /ext_hdd is already mounted with the external hard disk partition on your emulator VM
• Copy your SPTS video file from your host machine to /ext_hdd folder on the emulator VM 
• Note: The following command is performed from your Host Machine

• Back on your emulator VM, create a link in /opt/www/ to point to the external hard drive at its mount point /ext_hdd

• In the screenshot below, <your_spts_file_name> is assumed to be "received_spts1.ts" as an example.

Usage Instructions

Logging into your VM

As described in the previous section, you can log in to your emulator VM from your Host Machine using the ssh command.

Note: In order to learn the IP address of your VM, use the RDK Browser application “tab” key to navigate to "Device Info" which will provide you the IP address. Press "Enter" key to enter Device Info

Using rmfApp

Introduction

The rmfApp application is supported for all build types. Once you SSH into your emulator VM, you can play a video stream located at a url using a source and a sink.

Where is rmfApp?

rmfApp is located in the folder: /usr/bin on your emulator VM

How to run rmfApp?

Navigate to the folder /usr/bin and run rmf App using command ./rmfApp. After the initial log statements when the rmfApp starts up, press "Enter" key to get the rmfApp prompt - "rmfApp>"

rmfApp Command Line Options

root@qemux86:~# rmfApp [-source SOURCE] [-sink SINK] [other options] url

SOURCE can be: hnsource,qamsource

SINK can be:   mediaplayersink 

Other options include:
•        -recordingId <id>: id of recording to create where <id> is a decimal number
•        -recordingTitle <title>: title of recording

Example Sequence of rmfApp usage

Before using rmfApp, it will be better to terminate rdkbrowser as it may impact the performance of playback. You may use the systemctl command to terminate rdkbrowser as shown below.

rmfApp is located in the directory /usr/bin. Navigate to the directory containing the rmfApp:

Launch RMF App using the command below:

Once the app is launched, press enter again to get the prompt "rmfApp->":

Simulated Live Playback on a Hybrid Emulator

In a simulated live playback, the following rmfApp command maybe used to playback the local SPTS video file:

launch -source qamsource -sink mediaplayersink ocap://0x125d

Where 

• source : qamsource
• sink; mediaplayersink
• url: ocap://0x125d

Simulated Playback on a Hybrid Emulator

launch –source hnsource –sink mediaplayersink http://127.0.0.1:50050/received_spts1.ts

Where

• source : hnsource
• sink : mediaplayersink
• url : http://127.0.0.0:50050/received_spts1.ts 

Simulated Live Playback on a Media Client Emulator

 In a simulated live playback, the following rmfApp command maybe used to playback the local SPTS video file:

 launch –source hnsource –sink mediaplayersink http://<HYBRID IP>:8080/vldms/tuner?ocap_locator=ocap://0x125d

 Where  

• source : hnsource
• sink; mediaplayersink
• url: http://<HYBRID IP>:8080/vldms/tuner?ocap_locator=ocap://0x125d

Scheduling & Playing Back Recordings from the Media Client using Recording ID

RDK recordings on the Hybrid device are created from a cloud-based scheduler using json messages. Once the recordings are created, the rmfApp on the media client device can be used to playback the newly recorded media content. 

This section outlines the use case:

Step 1: Preconditions / Prerequisites: 

• As the hybrid VM has very limited memory and as recordings are by default stored in /opt/data/, you should create a new directory /ext_hdd/data within the external hard drive that we had set up earlier and also create a soft link to /opt/data

Note: The above directory and the soft link needs to be in place each time before scheduling recordings. 

 Your recordings will get created in the following path on the Hybrid VM:

If there is a media file created in the /chunks folder above, then the recordings have been successfully created.

Step 2: Launching rmfStreamer on Hybrid VM

There are multiple scripts in the folder /usr/bin. There are two scripts for launching rmfStreamer:

• rmfstreamer
• rmfStreamer

Note that the name of each file is similar apart from the usage of upper case and lowercase "s" in each file name.

Launch rmfStreamer using the script: rmfstreamer

if you run in into issues accessing rmfstreamer, then change the access permissions of file appropriately:

Once rmfStreamer starts, you will see log print statements on the console.

Step 3: Start playback of recorded content on Hybrid emulator from your Media Client emulator

Now you can playback from the media client using the rmfApp on the media client VM using the following sample commands:

Note: Where the recording id is "6" as set in the schedule.json message from the server. Users may write a small application to simulate the scheduler server json messages.

Westeros and WPE-webkit Support on RDKV Emulator

RDK emulator supports westeros compositor and renderer module as westeros-renderer-gl

Building WPE-image:

# To build the same for different build types, use the below command
  
#Hybrid
MACHINE=qemux86hyb-morty source meta-cmf/setup-environment
bitbake rdk-generic-hybrid-wpe-image

To test WPE image from the VM console

1)Boot the VM in NAT mode and ssh in to the VM to get the console as mentioned above.

ex: ssh -p 2222 root@localhost

2)Then type the following command

To support westeros surface width and height are HD so emulator need to set HD resolution

To enable support for 1280x720 resolution in emulator please follow the steps mentioned in this page.
This will help us in adding custom resolution in Virtual Box.

Bringing up the Emulator on VMWare Player

Install VMplayer in Host Machine

Use the below Link download to install VMware Player on host

https://my.vmware.com/web/vmware/free#desktop_end_user_computing/vmware_player/5_0|PLAYER-504|product_downloads

After downloading

sudo ./VMware-Player-<Version>.bundle (LInux OS)

Run  VMware-Player-<Version>.exe  (Windows OS)

Reason for VMplayer: in Mesa Higher versions EGL-PLATFORM fbdev is not available as it is deprecated so we tried using DRM (Direct Rendering Manager driver for graphics)

for DRM driver is available only in vmware only (vmwgfx so we have gone for VMware Player)
 

Steps to bring up RDK Emulator on VMware Player

1        Once VMware Player is installed, open the VMWare Player  using the command

vmplayer &  or open using GUI


2       Click File --> Create a New Virtual Machine --> Select  'i will install my operating system later' --> click Next

3       Select 'Linux' --> Version  'Other Linux 3.x kernel' --> Click Next --> Give name --> Click Next

4       Maximum Disk Size : 8 Gb --> Select 'Store Virtual Disk as a Single File' --> Click Next --> Memory for this Virtual Machine '512 Mb' --> Click 'Close'  --> Click  'Finish'

5       Click 'Edit virtual machine settings' --> select Hard Disk (IDE) --> Click 'Remove'   -->Click  'Add'  --> Select Hard Disk  --> Select  'Use existing Virtual Hard disk'

6       File browse and set the path to the *.vmdk  file --> Click Finish --> Click 'Keep Existing Format'

7       Network Adapter select Bridge Adapter  --> Click Save

8       Click Play Virtual Machine

         Cannot connect the virtual device ide1:0 because no corresponding device is available on the host.
         Do you want to try to connect this virtual device every time you power on the virtual machine? [YES] [NO]

          You select [NO]

9       This will bring the emulator up with the initial splash screen followed by RDK-Browser as startup application.
