Transcode and Add Pulse Video Analytics to Video Content on Cisco Show and Share
Revised: February 26, 2013
When Cisco MXE 3500 integration is enabled in Cisco Show and Share, videos uploaded to Cisco Show and Share are delivered to the Cisco MXE 3500 for transcoding. When the transcoding is complete, the transcoded videos are returned to Cisco Show and Share.
•Guidelines and Limitations
•Configure the Cisco MXE 3500
•Register the Cisco MXE 3500 in the Cisco DMM
•Configure Cisco Show and Share to Use the Cisco MXE 3500
•Testing the Integration
•Cisco Show and Share Release 5.2.1 or later.
•Cisco Media Experience Engine 3500 (MXE 3500) Release 3.2 or later.
•Administrator login credentials for the Cisco Show and Share and Cisco MXE 3500.
•Cisco MXE Release 3.3 and Cisco Show and Share Release 5.3 are required for Pulse video analytics.
•For Pulse Analytics, the Cisco MXE 3500 must have a Pulse feature license installed.
Guidelines and Limitations
•You can only configure one Cisco MXE 3500 or Cisco MXE 3500 cluster in Cisco Show and Share.
•There is no co-location requirement for Cisco Show and Share and Cisco MXE 3500 hardware. The appliances can be deployed anywhere in the network provided that they can communicate by using FTP (TCP port 21) and HTTP (TCP port 80). Cisco Show and Share uses FTP to submit user videos to Cisco MXE 3500 and retrieve transcoded versions, and uses HTTP to submit transcoding job requests. If network loading or bandwidth are a concern with large video files, Cisco Show and Share and the Cisco MXE 3500 should be co-located.
•The Cisco MXE 3500 licenses, Standalone and Resource Manager, both work for this integration. Other than the functional differences between the two licenses, there are no specific configuration limitations.
•When integrating Cisco Show and Share with a Cisco MXE 3500 cluster (resource nodes managed by a resource manager), observe these guidelines:
–Verify that the resource nodes (RNs) have full control access to the \\mxe_ip_address\dms shared folder on the Resource Manager (RM) appliance. mxe_ip_address is the IP address of the standalone or the RM appliance.
–When configuring the host setting, we recommend using the IP address for the RM. Verify that the RNs can reach the RM IP address.
•Configure the FTP client settings on Cisco Show and Share to communicate with Cisco MXE 3500.
•If Pulse video analytics is enabled, the processing time to add keywords and speaker identification is approximately 1.5 times the length of the video. A one-hour video takes approximately one and one-half hours to process.
•In Cisco Show and Share Release 5.3, videos are transcoded to MP4 format using the H.264 video codec. You can configure the transcoding process to produce up to three versions of the video using different resolutions:
–360p—Low resolution. The Cisco Show And Share mobile client displays videos in this resolution. Viewers can also select this resolution for smoother playback over slow connections.
–480p—Medium resolution. Videos transcoded to this resolution are also transcoded to 360p.
–720p—High resolution. Videos transcoded to this resolution are also transcoded to 480p and 360p.
Table 1 Transcoded File Specifications
Note Cisco Show and Share does not upscale a video. For example, if you set transcoding for all three resolutions, and upload a video at 480p, Cisco Show and Share will only produce the 480p and 360p versions of the video.
•Integrating Cisco MXE 3500 Release 3.3 that has Pulse video analytics enabled with Cisco Show and Share Release 5.3 adds keywords and speaker identification to video content. In Cisco Show and Share, viewers click on the keyword or speaker to go to the corresponding location in the video. Pulse Video Analytics is a licensed feature on Cisco MXE 3500 Release 3.3.
•In Cisco Show and Share Release 5.2.x, videos are transcoded to Flash video 8 (.flv) format with the following specifications:
–Bitrate: 400 bps
–Frame rate: 30 fps
–Maximum height: 268 pixels
–Maximum width: 480 (for 16:9 ratio), 360 (for 4:3 ratio)

Testing the Integration
Cisco Show and Share now automatically submits transcoding jobs to the Cisco MXE 3500.
Step 1 Upload a video to Cisco Show and Share, and save it as a draft.
Step 2 Log in to the Cisco MXE 3500 user interface.
Step 3 Choose Monitoring > Job Status. A job will be running without a Job Profile Name.
Step 4 Select the job.
Step 5 The Tasks tab displays the job details. When the Cleanup task is complete, the Cisco MXE 3500 has completed the transcoding and deleted the submitted video from the C:\dms\input folder.
Step 6 On Cisco Show and Share, the status of the uploaded video will change from Processing - Draft to Draft. You can now publish the transcoded video in the Cisco Show and Share video portal.
Figure 7 Job Details in Cisco MXE 3500
1. Upload Video to the Cisco Show and Share video portal.
Tip If you have Pulse video analytics enabled, upload the video as Draft. This allows you to review and edit the Speaker names before publishing the video.
The status shows as Processing-Draft. If you select the Go to Publish Page option when the video is uploaded, the status shows as Processing-Publish.
Cisco Show and Share submits the video by using FTP to the Cisco MXE 3500 for transcoding. The Cisco MXE 3500 transcodes the video; if Pulse video analytics is enabled, Cisco MXE 3500 also applies keyword tags and speaker IDs to the video content.
Cisco Show and Share uses the MXE API to submit and poll the status of the job it submitted. When the Cisco MXE 3500 completes processing the video, Cisco Show and Share uses FTP to copy the transcoded video to the Cisco Show and Share video portal.
2. After the status changes to Draft, click on Edit Video to review and edit or tag the speaker names.
If the Go to Publish Page option is selected during video upload, the status changes to Published. The video is automatically published to Cisco Show and Share. To review and edit the speaker names, click Manage Video, then Save as Draft. In the draft copy, click Edit Video to edit or identify the speaker names.
Once a speaker is identified, the system recognizes and automatically identifies the speaker in subsequent videos.
3. Publish the enhanced video content for sharing.
