Forums -> VideoSaver -> Mpeg2 videos stretched across 3 screens.

I have successfully done this on one system with a tri-panel, but not another system with different specs, both are very nice workstations.

I'm noticing that some mpeg2 codecs seem to allow this tri-panel stretching of videos with VideoSaver, and some mpeg2 codes do not.

How do I determine which do versus which don't?

I guess I am looking for a way to determine which mpeg2 codec videosaver uses.

The only detection software I know if is called GSpot, but it doesn't tell me which mpeg2 codec VideoSaver is using.

VideoSaver uses the default MPEG2 codec, should be the same one used by Windows Media Player.

The following could prevent the video from getting stretched across all monitors:

- the codec doesn't support multiple instances

- the codec requires a video overlay, but overlays are not available on all monitors

Yeah, I seem to have noticed this. When I install 1 mpeg2 codec, Windows media player plays video's rather choppy on this one workstation, and of course, it figures, that the mpeg2 codec I have that plays the videos choppy, is the same one that has slow and choppy performance while stretching across 3 screens.

When I then remove that Mpeg2 codec and default to the regular windows Mpeg2 codec, the video playback is perfectly fast, but then doesn't strecth across 3 screens. VideoPlayer errors out.

So, it sounds like so far, I have tested only 2 mpeg2 codes, the default windows one, and another one located here:

And one thing I noticed, is the free one I d/led is very old (2000 to 2002). Perhaps it is too old, and I should try a different one?

Do you happen to know about how many different mpeg2 codecs exist?

Sounds like I need to find the right one that will allow me to stretch an mpeg2 across all 3 screens without performance drops.

On the 1 machine I have, I am able to use this older mpeg2 codec just fine.

I'll also have to look in to the overlay option. I looked on the cards drivers but couldnt find that option. I'll have to double check.

The MPEG2 codec from Elecard might be worth a try.

MPEG2 codecs also get installed together with DVD players like WinDVD, etc.

Yeah, I tried that one, was too choppy for me with 3 screens:

Elecard MPEG-2 Video Decoder file: ver. 1.1.4586.5065 = 3 screens but too choppy.

Ligos MPEG Video Decoder file: ver. = 3 screens but too choppy.

The above are the 2 I tried on 1 system. Those 2 codeces both allow stretching the videos with VideoSaver but the performance is very very choppy.

If I use another codec, one that doesnt allow stretching, I can play the same video on all 3 screens at once, but it is 3 screens of the same videos playing on each one, instead of one video being stretched on all the screens.

I wish I could tell which mpeg2 codec I was using on the system with the tri-panel that gets great performance is using, but MS video decoder checkup program doesn't show which codec is being used until you hit the Select Preferred codec button.

I notice that MainConcept codec is installed on the good sytsem. I wonder if that one is the right one. Tried installing it on the other tri-panel but it didn't install correctly.

I'm trying to compile a list of which mpeg2 codes allow stretching onto 3 screens. So far I have confirmed the 2 above. I can see this may turn into a long drawn out process, but it is a learning experience.

I need better tools than Gspot and MS Vid Decoder Checkup Util.

I'm not aware of a tool which shows the default MPEG2 codec, let me know if you find something.

Try Final Codecs 2008
This program gives you control over most codecs
