Mobile Video Delivery Support Frequently Asked Questions

General

I'm building an application for iPhone/Android/BlackBerry. Can I use yospaceCDS to supply video to this application?

Yes. You will need to read one of the supported output feed formats into your application (we suggest MRSS).

I'm building an iPhone application on OS 2.x. I want to offer high quality video when the device is in WiFi coverage and standard quality otherwise. How do I do that?

Read our article on access URLs. You will be able to detect which network the iPhone is on and programmatically adjust the access URL accordingly. The next release of yospaceCDS will support iPhone OS 3.x automatic bandwidth detection.

I am building an application that will manage video content structured in a variety of ways. I want to use yospaceCDS to support mobile delivery, but structuring content in feeds so it can be ingested through the Content Management Console doesn't fit my application model. Is there anything I can do?

You can use the lower level Web Services API to put content into yospaceCDS and request the content through the yospaceCDS delivery system to take advantage of automatic device and format adaptation.

Feeds and Formats

I can't find such and such a video format in the Feed Type list? How do I select the video format for my feed?

You don't need to. This is done automatically by yospaceCDS. The reason for this is that the Feed Type relates to the syntax of feed of videos, rather than the format of videos themselves. The Feed Type relates to the syntax an embedding application needs to be able to show the videos to the end user. When the user selects the video, a call is made to yospaceCDS which determines the correct format for the accessing device. This is carried out by the yospaceCDS internal device targeting system.

I have a new device, how do I get yospaceCDS to recognise it, and provide the correct video format?

Email support@yospace.com with the User-Agent that the device supports and the video format(s) it supports.

I have 10 items published in my feed, but there are more than 10 items in the Content Group that feeds it. What is going on?

The output feed could be limited to 10 items. Check the output feed settings.

Or, the items have been marked for deletion by the input feed. They are not immediately deleted to allow devices that have a cached URL referencing the video not to receive broken links. You can check the status of a video item, by selecting Edit and choosing the RSS Details tab.

What kind of formats can yospaceCDS accept?

Most formats are supported; this includes MPEG-2, MPEG-4, MPEG-4 AVC (H.264), FLV (H.263), AVI, MOV, WMV, etc.

Does yospaceCDS accept Flash Video files encoded in H.264?

Yes.

I have tried to upload a video without a sound track, but it appears in the Content Management Console with an error flag, what has happened?

Currently, yospaceCDS only accepts video files with an audio track.

Devices

When I test video access on my Blackberry, I get an error message appear stating "HTTP Error 413 Request entity too large". Why is this?

Make sure that you are accessing the video content via the "Internet Browser". The BlackBerry browser operates through the MDS and imposes a maximum file size limit. This size limit can varies depending on your MDS configuration, and usually is 100K, but can be configured to 1MB.

If you are using the Internet Browser and still get this message, check your media limit under Media/Options.
