Controlling Movie Files

[laumh]

Is it possible for a subject to manipulate movies within MediaLab? I'd like to show the subjects several videos and have them perform a series of ratings on the videos, but I'd like for each movie to be paused and repeated at will by the subject. The only way I can think of is to create a powerpoint file to do this, but is there some other way directly within MediaLab?

Was just working on this--try opening the attached html file (see below) in a text editor and change "test.mpg" to the name of one of your videos. Put the video in a folder with the html file--and then open the html file in IE--does it play? If so, you can present this simple HTML page as a background to any item--simply modifying the the name of video clip. For the background, just specify:

embed.htm (t.1,l.1,w.5,h.5)

Or whatever works given the size of the video. There are other settings you can change in the html file if you want to experiment.

I have been trying to get a video into an html page but everything I'm looking up needs a server, which we don't have because we're not trying to make a web page- just questionnaires. The video needs to be able to be stopped/started and play automatically. I tried using the embed.htm file as said in the post above and the video did not play.

Does the posted sample work if you run it unaltered? If so, what kind of video are you trying to play?

No, the posted one does not work. It displays the windows media player but not a video. I am trying to play a .wmv.

Things seem to have been affected by the release of the newer version of the Windows Media Player.

Try typing these lines (one at a time) from the Run command on the Windows Start Menu:

regsvr32 wmpdxm.dll
regsvr32 wmpasf.dll
regsvr32 wmp.dll

That registers three important files that are required in order that the new WMP handles the embedded video rather than the old WMP. Try that and see if it helps. I've attached a slightly revised embed.htm file also. It has these comments included as well as a line that prevents IE from issuing a hassling statement when trying to open the html file.
