Streaming Video

The information on this page is for viewing embedded video, for information on downloaded Mp4 (video) and Mp3 (audio) files, please see the appropriate section

I can't see any embedded video

To view embedded video within a webcast page, you will need both Javascript enabled, and Flash Player Version 10 installed. To check which version of Flash Player you have installed, see How to I check which version of Flash Player I have installed?

Please note that some Webcasts are 'audio only', and have no embedded video.

If you get an error such as 'Server not found' and have never been able to view our embedded video, you may have to check port 1935 on your firewall. If you're in a corporate environment, you will need to check with your local IT staff as to whether this is the case. Alternatively, on home broadband, you may need to open this port on the router if it is not open already.

I get the 'Flash, version 10+ and Javascript are required to view this video within the page' error - but I've got Flash!

Check that Javascript is enabled in your browser, and you have Flash Version 10 installed. It may be that you have an older version of Flash Player - see 'How to I check which version of Flash Player I have installed?'

You may also be running a very old version of your browser software which we may not be able to support. It is recommended to run the latest version, at the very least from a security point of view. Updating your browser is beyond the scope of this document.

How do I check which version of Flash Player I have installed?

To check the version of Flash Player you have installed, go to http://get.adobe.com/flashplayer/. You should see a line like 'Adobe Flash Player version 10.0.42.34' - if you version number starts with a 9 or lower, you will need to upgrade your version of Flash.

Playback constantly buffers / stutters

Our higher quality video may not be appropriate for all connections. You may find playback smoother viewing the lower quality version which is approximately a third of the size.

There may also be other programs running on your system which may use a lot of bandwidth - Peer to Peer applications such as Spotify, BBC iPlayer (the downloadable version), and other programs using the BitTorrent protocol can be particularly bandwidth hungry.

Occasionally other programs on your system may be using large amounts of resources, which may cause your browser to become unresponsive. Ensure that there are no memory intensive programs running if you encounter issues.

How do I view full screen video?

There is a 'view full screen' button the far right of the embedded player. Clicking this should make the video full screen. To leave the full screen display, you can press escape, or press the same button again.

I can't hear any audio

There are multiple places where audio levels might be set or muted. Firstly check whether you can hear audio on your computer; you should check the volume level on your computers speakers (and that they're not muted). Next, check the volume bar on the embedded player.

The audio is out of sync

Occasionally, audio may become out of sync with the picture, usually if you jump around the timeline in particularly long videos. Pausing the video briefly often rectifies this, but if you find it happening consistently in one video, please email webcast@oii.ox.ac.uk so we can double check the encoding of that video.

How do I embed video in my blog/website?

Under each webcast which has embedded video is a link - 'Show Embed Code'; clicking on this should reveal embedding options for cut and pasting into your website. Most webcasts have two quality settings, 'low', which is 320x180, and 'high', which is 640x360.

If you use Wordpress, or another similar content management system, you may need to cut and paste this code in the 'HTML view' or 'Source Code' view.

If you have further issues, please see 'Embedding doesn't work with my website'

Embedding doesn't work with my website

Cut and pasting the embed code directly into a Rich Text Editor will often lead to the <embed> codes being stripped out. To avoid this, you can usually paste directly into the source code or HTML view of the editor.

In some content management systems such as Drupal, you may need to explicitly allow the <object> tag in the input filter to prevent it being stripped out.

Check the source code view of your site to see if the <object> code is actually making it through to the browser.
