Any Xvid Experts can tell what I did wrong, details below

[TBoneit]

Hello, I have some Xvid AVis that do not play in teh Toshiba 3990, they just say loading forever.

Details: from MPEG4Modifier

Packed bitstream: Yes
QPel: No
GMC: No
Interlaced: No
Aspect ratio: Square pixels
Quant type: H.263

I-VOPs: 727 (0.84%)
P-VOPs: 34367 (39.94%)
B-VOPs: 50949 (59.21%)
S-VOPs: 0 (0.00%)
N-VOPs: 0 (0.00%)

Max consecutive B-VOPs: 2
1 consec: 45.56%
2 consec: 54.44%

In my testing I tried unpacking the Packed Bitstream, w/mpeg4modifier, no help, Tonight as test I took the troublesome AVI, used source audio, w/direct stream copy which should eliminate the audio as the problem. Took the Video chose full processing mode divx 5.2.1 home theatre profile using Vdub. This file played normal. So I'm guessing that the AC3 audio isn't the p[roblem and something in the Xvid settings I gave above is the source of the problem.

I'd like to pin down what works and what doesn't with this player so I can avoid doing encodes twice. BTW The player is supposed to support Qpel and GMC but this is an older encode from when I wa sthinking about the Phillips 642 wjhich as I understand it did not support those features.

Many thanks

Make sure the fourcc is DX50.

[TBoneit]

Shouldn't the Fourcc match the Xvid? I play Divx 3 & 5.x and Xvid in this player all the time. Sorry if that is a stupid question?

However as a test I will try that, what have I got to lose? Oh yes, the cost of the disc and this is where those cheapo 10cent discs come in for problem testing.

Did you finalize the disks?

Did you finalize the disks?

Excellent question. If the movie is right at 702MB, the extra info on an unclosed disc will make the data too big for the disc.

Sometimes when a disc will not play in my DivX players, I will direct stream copy them into a new contrainer. I have a couple of movies that MPEG4Modifier says are corrupted but one I used DivXFix on and the other I direct stream copied in VDub and both discs play in my players.

Looking at the original post I can see I forgot to say DVD. Which does work fine in this player. Sorry about that.

a. Finalized discs? Always.
b. DVD and never quite full.

Most Divx/Xvid play from the DVD fine, some do take a little longer loading of course.

I moved to DVDs when Sony came out with their Dula format DRU-500a and never looked back. I'm still using the last of the 50Pack CDs I bought early last year on sale (Fuji MIJ) when Staples had them for $8.94 a 50 pack

With the Toshiba I can even mix Divx3, Divx5 and Xvid and MPG for example on one DVD Disc and they all play.

It is just these 8 files from the same time that seem to do this loading forever problem. I'm trying to learn what went wrong to learn and to be able to avoid this problem in the future. I may have only paid 30cents for the Verbatims I use but I don't like to waste them and the time to burn and test. When they go wrong I feed them into the shredder. I only kept these for investigation, once I figure out what happened then they'll be for the shredder too.

OT: If I could only find an affordable shredder for Water/Soda/Milk bottles I'd be set.

Anyway does anybody see anything grossly wrong in the data I posted in the opening text?

Many Thanks for the help.

if you changed the fourcc and nothing, then the player either doesn't like 2 bframes.. or maybe there's a VBV issue with the encode that's not compliant with the player. Download this utility http://download.divx.com/labs/Fuse02182005.zip and see if what info it spits out on the file. usage is simple:

example
Fuse -v inputfile -o test.avi

Cheers

I don't know your player in particular but many Divx players will have problems with:

Frame rates over 30 fps.
Frame sizes over 720x576.
Bitrates over ~2500 kbps.

Divx Ultra certified players excepted.

Thanks. Ok, I think I see the problem, VBV test failed. 23.976 and 640 x 272 and approx 1000kb bit rate so its gotta be the VBV. Now I know what to avoid. Many thanks. I hate unsolved puzzles.

I usually encode my Xvid files with no B frames at all. The only reason they save space is because they use a higher quantizer value (lower bitrate, lower quality).

[TBoneit]

I'm thinking I just play safe and use the Divx 5 Home Theatre profile and up the bitrate to 1500 or so which should still let me get 2 movies onto one disc or 8 episodes of TV shows vs the 1 movie or 4 episodes I've been putting on as standard DVD format.

It isn't quality of Divx vs DVD or saving the discs, It's saving the space as that is my limiting factor. I've already gone to Standard size DVD cases that hold 2, 3, 4, or 5 discs to save space on the shelves. Now if I can double the disc content I can get twice as much in the same space.

Anyway, enough rambling
Many Thanks. This has solved my curiousity and helped me decide on the proper path for future encodes. Most of the Std DVD format discs I create in the future will be home movies for redistribution to other family members. Next big project 8mm Film to DVD.

Many Thanks for helping out.
