SUPER for Xvids

[David K]

I've been fooling around with it, converting from mpeg to xvid, but the resulting avi files are not recognized by some other programs (Virtual Dub, Windows Media Player, Media Player Classic.) Something odd in the header; these programs do not recognize the Xvid codec in the Avi file. (And yes they recognize it with Xvids encoded with Virtual Dub on my machine.) Anyone else having this problem?

[celtic_druid]

Not used SUPER myself, but I have encoded with XviD via mencoder which I believe it uses. No problems with the resulting files. How large were the avi's though? Because some mencoder builds will have problems with output over I think 1GB.

If I want quality, I use VirtualDub Mod or one of the VirtualDub variants because of the control and the options.

I reserve SUPER for the less common formats when quality is not the major concern. I haven't tried it for MPEG to Xvid. I don't know why it would output a non-standard Xvid, though. You might drop one of the non-standard ones into Gspot 2.52 and see what is different about it.

[David K]

G-Spot can find some of the information in the header (like xvid) but it doesn't find all of the information like those boxes which indicate BVOP NVOP.
The files are not larger than 1GB.
I would agree that Virtual Dub is a better bet for Xvids, but I wanted to try it out with SUPER. The files do play on my Oppo stand-alone player and look good, but I'm concerned that they are not compatible with other programs.

This is the error message I get in Media Player classic when trying to play a SUPER's Xvid avi.

Which version of GSpot are you using, and which version of XVid?

[redwudz]

That sounds more like a codec problem than a player problem. Especially if VD doesn't accept the file. I just tried converting a MPEG to Xvid with SUPER and VirtualDub had no problem opening it. I used the default settings in SUPER. Maybe something there was set different, though I don't see any settings there that should bother VD.

Or maybe there is a problem with your Xvid codec when playing back the file. In that case VD probably wouldn't accept any Xvids, though.

Yes it is weird because VD recognizes other Xvid avi, but it doesn't recognize the ones from SUPER.
This leads me to believe that the way SUPER is writing its header is confusing to some programs.
AVI-Mux Gui file info feature's analysis of the SUPER avi describes some of the header information as written by a broken program.

I was resizing in my encodes with SUPER (480x480 to 640x480 but it did not actually resize), so perhaps that was the added complication.

[Ai Haibara]

Hmm... what happens when you uncheck "Use DirectShow" in SUPER? Also, you can try switching between mencoder and ffmpeg for encoding, to see if that helps.

[David K]

If you want the whole story, I did try the various options.
It just crashed with the direct show option enabled, so I disabled that.
Using mencoder made Xvids that froze after the first few frames.
Using ffmpeg gave me Xvids that did play on my Oppo stand alone DVD player, but had the header problems that started this thread.
My sense is that right now SUPER is good for simple format to format conversion, but buggy if you want to do other things as well (like resize, especially from a non-standard resolution).

On your Oppo, or on the computer?

Well... someone more familiar than I with the inner workings of ffmpeg and mencoder would have to reply, here, though I thought they didn't have problems with resizing, from most resolutions. I don't know if recent builds (or the custom builds used in SUPER) encode for a specific version of XVid, either.

I'm not sure, but you might also try utilities like AVI Recode. I don't know if that'll fix the header problems, though.

[celtic_druid]

Most builds are statically linked, so they use whatever lib they were linked against. Can also be linked dynamically though in which case the version is determined by whatever build of xvidcore.dll you have.
