Playing Videos in DirectRT- sound only

[lelliott10]

Hello,

I am trying to display several short videos in Direct RT. The files are in .mpeg format and play without a problem in the Windows Media Player. When I run the input file, the screen is black but I can hear the audio portions of the videos. I just can't see any images.

I tried using a different computer in a different lab and ran into the same problem.

What can I do to fix this?
Thanks.

What version of DirectRT (200x.x.x) and Windows Media Player are you using? And this is Windows XP? Also, can you attach a copy of your input file?

Thanks for your reply.

I am using version V2004.3.0.24 and the Windows Medial Player is version 9.00.00.3349. Yes, the computer is using Windows XP. Also, I've attached my input file.

Your help would be greatly appreciated!

Well, your input file is pretty straightforward! I would suggest trying clips from some other source to see if it has something to do with the encoding of the clips. If it does this regardless of the clip, then I would suggest downloading and trying v2008 just to see if it's a version issue. Or, if you if you like and the clips are short enough feel free to send me one via support@...com and I'll try it out here.

I downloaded a video from a random website and WAS able to run it in DirectRT without issue.

What does this mean for me? I really need to use the videos that aren't working. Is there anything I can do? I'll try to upload one of them.

You may be missing the codec intended to be used for the video on your machine--perhaps the Windows Media Player is adapting and using something else, whereas DirectRT is not being so flexible. When I play the video in the Windows Media Player, and check File > Properties, I see that this video uses the CyberLink Video/SP Decoder (PDVD7). Do you happen to have that on your machine (check My Computer > Hardware Device Manager > Sound Video and Game Controllers > Video Codecs > Properties). If not, do you have a copy of the Cyberlink Software that was used to create the video files?

I followed your instructions and checked to see if I have the Cyberlink codec and I do not. Also, I do not have a copy of the software used to create the video files. I'll try to see about getting a copy of the needed codec.
