Xvid Nightmares

[MonaLeilani]

It first started out like this. I had a file I recieved in Xvid format.
I decided I wanted to convert it to Divx as the 100 fps of the movie bogged down my system (even though it has a 128mb vidcard and 2ghz proc ;_.
I was instructed to use a program that came with my Xvid codec, Nic's Mini AviC FourCC Changer. I switched it from its original setting (xvid, I think it was) to Divx. But now, nothing encoded in Divx will play. Nothing. I get this error message upon loading a file in Divx.
Alert: This file contains unknown video data.
The video file you are opening includes video data that is not
recognized by the DivX player.
The file contains the following type of data:
Video data: FOURCC code "Div3"
You may need to install a new video codec on your computer to watch this video.

You can pretty much substitute DIV3, XVID, DIVX, etc. for the "DIV3" box in the error...I've tried switching them but nothing seems to work. By the way, I have the newest Xvid codec, and the newest DivX player. I'm about to tear my hair out. I've made things worse for myself. I complained about my machine freezing up constantly while viewing the file (even with newest codec) and now I've made it so I can't view ANY Divx and Xvid encoded files. Can anyone help me?..

1) It's extremely hard to understand how changing the FOURCC header code on just ONE video file could possibly affect ANY player's ability to playback OTHER video files.

2) It's also hard to believe that ANY video of ANY type was encoded at 100fps - 23.976, 24.0, 25.0, 29.970, 30.0 perhaps, but not 100fps.


I would speculate that you were "given" a file that contained a virus...


Just curious - Since changing that one file's header, have you tried playing any videos in Windows Media Player?

[MonaLeilani]

1) I think I fixed this problem. I think I screwed up some of my codecs, so I downloaded them fresh again and reinstalled and all was well. Except for the video being upside down. But I fixed that.
2) Let my screenshot speak for itself.

Anyway, all is well now, but does anyone suggest a way for me to watch these videos without my computer crashing? My hardware should be good enough.

And I stand by what I said previously:

It's also hard to believe that ANY video of ANY type was encoded at 100fps - 23.976, 24.0, 25.0, 29.970, 30.0 perhaps, but not 100fps.


It is, however, possible (as you well know, based on what you first tried to do) that someone altered the header information of this video.

Just as an experiment:

1) Load the file into VirtualDub

2) Set BOTH "Video" and "Audio" to "Direct Stream Copy"

3) From under the "Video" dropdown menu, select "Frame Rate" - and select "Change to" 30 "frames per second" (You have to enter the amount of 30)

4) Save with a new filename

I tried what you said. The video moves choppily and slowly.

whoa... that is some pretty hefty chunk of movie there. how big is the file?

[MonaLeilani]

That particular file is about 174 mb. I still have problems being able to view it. The picture is fine, but it must really put some pressure on my system. Divx crashes periodically (i.e. every other 30 seconds) while viewing the episodes. I just don't get it. ::insert crying face::

[MonaLeilani]

Hahahaha...I just realized what my problem was. I had two different Xvid decoders installed on my computer. I download ffdshow, or whatever its named is, and installed it. Later on, I installed koepi's build of Xvid...I uninstalled ffdshow and everything works great now! Smooth as my other files.
It may also help I'm using bsplayer now, too. My memory usage is almost normal now that I play that file.
Anyway, thanks for your help.

"Anyway, thanks for your help."

Glad to hear that you've resolved your problem.


Just curious, now that things are performing properly, how does that experimental file (30fps) playback?

I guess by repeating your post I should interpret that to mean you played the experimental file both before finding your solution and after uninstalling FFDShow - and there was no change in the playback.






(If so, oh well... That's why it's only an experiment)


Once again, glad to hear you're now a happy camper ;>}

[MonaLeilani]

Oh, I see what you mean. I played the file before I uninstalled the ffdshow, yes. After your most recent post, I tried it again, with the same results. I guess it just is happy at 120 fps :/
All is well with playback, so...I'm not much worried about reencoding it. :|
