Multiple XviD codecs?

[LighthouseJ]

I have a few files that use koepi's XviD codec (http://www.roeder.goe.net/~koepi/xvid.shtml), and some that use Nic's XviD codec(http://nic.dnsalias.com/). Of course only one codec can occupy the C:\WINDOWS\SYSTEM32\xvid.ax file, so that means I can only watch files that use one codec at a time. To watch a file that plays properly in the other codec, I have to uninstall the current codec and install the other one I want. One codec can open the others' file, but there are too many video errors to simply ignore.

Is there a way to get the two to peacefully co-exist? I like BSPlayer so if I could tell it to use one XviD codec for one set of files, then another codec for another set of files.

All of those will decode Xvid equally as well. The only real difference between the three comes into play when you are actually encoding.

are you sure that you need to reinstall the old nic build of the xvid codec to watch old files
im pretty sure that the XviD - Koepi 1.0 RC1 is backwards compatible

before installing the new XviD - Koepi 1.0 RC1 any new files which use it would not run
after installing the XviD - Koepi 1.0 RC1 all my old xvid files still work which leads to my thinking of backward compatability

the only difference i noticed between the pair of codecs was the options screens when setting up to encode
is it just me or do other people find that the new XviD - Koepi 1.0 RC1 encodes a fair bit faster

Yeah, here's an example of the differences I experience. For example, you have a video of a ball dropping from the top of the video to the bottom. If the video is encoded in one release and I play using the difference release, then you see the pixels and blocks above the ball become distorted and skewed. Given this is a simplistic example, when more action happens, it makes the video unwatchable at times, and I have to wait for a keyframe.

Well, I'm watching some files encoded right now with Nic's using Koepi 1.0 RC3 and for the most part it plays but there are times when the above happens with the artifacts. I used to have RC1 installed and the compatability was a lot worse though.

Have you tried using ffDshow to see if it handles both well?

I personally prefer it over any Xvid decoder. You can pick up a copy of it here: http://athos.leffe.dnsalias.com I am currently using the Feb 25 2004 build (too lazy to check out any newer ones), but you should be ok using the latest one.

Yeah, the packaged codec pack that came with the Koepi's codec pack prescribes the usage of ffdshow (alpha 2003-05-23). I tried it but the xvid.dll file kept crashing, and found through trial and error that I was better off without ffdshow.

I downloaded and installed the March 25th 2004 release of ffdshow and I'm looking at videos encoded using both codecs and it looks like we have a winner. I liked the post-processing options from the earlier version and I'm glad to have them with the newest version of ffdshow that can show all of my XviD videos.

is the fragmentation in this xvid avi screenshot should be below due to this
i will try using the reinstalling the old xvid codec so that it occupies the C:\WINDOWS\SYSTEM32\xvid.ax file
interesting hope it works as i have a couple of old files with fragmentation
i thought it was down to a poor download or just that the source file was badly made

your right the 2 codecs do perform differently
my old nic build works fine
most strange

hope that it is fixed in a future version of the codec

it is very odd that it is only noticable on a couple of videos
there must be a certain setting that the new rc1 codec doesnt handle well/at all that certain people used when encoding
