View Full Version : Xvid choppy video on portable video player, but not DiVX

I've got a Wolverine MVP which I primarily use for offloading and display of videos and photos from my and other people's cameras (has lots of built in card reader slots), but I often throw some of my editted videos onto it to show off to other people.

I've had no problems with DiVX+mp3 encoded AVI videos up to about 1000kbps. They play smoothly, and audio is in sync.

I've recently been encoding some of my editted stuff with XviD because the motion tracking and detail tends to be better and it encodes faster. Everything plays fine on my PC, but on the Wolverine the video is choppy. It's dropping frames left and right.

I've started with all the defaults and then tweaked pretty much
every setting I could find in XviD codec resulting in high quality, low quality, high bitrates, low motion tracking, high motion tracking, xvid files with xvid versus divx fourcc, 1 pass, 2 pass, MPEG, H.263.. etc etc. None of it changes a thing.
In the end, all DivX encoded videos play smoothly, and all XviD encoded videos play choppy with dropped frames.

Here's a directory with one divx and a bunch of xvid samples of the same clip, if someone wants to test on their own portable player
http://www.thud.us/videos/misc/xvid-samples/

I've seen various references to XviD not getting along with some players. Is this just one of those things, or is there still a trick that I haven't tried that might help this?
Any help would be appreciated.

All of your xvids have two consecutive b-frames, the divx has 1. That's the only difference that leaps out at me. Give it a try with one and see if that changes anything.

I think this is more appropriate for the hardware forum.

zzzz...

That's odd, I don't see *any* other questions like mine
in the Hardware forum. Can't change anything on the
hardware side anyway. I'd have thought the XviD setting
experts would be in the XviD codec forum.

I'll give Max consecutive BVOPs = 1 a shot.

Try disabling Packed Bitstream if you're using more than 1-consecutive bframes.

A friend of mine is trying to figure out some decent XviD-presets with vast standalone-compatibility, basing on Teegedeck's presets, that don't take such things into consideration.
Yet even he thinks that 2 consecutive B-frames and QPEL should be supported, aiming at newer & better standalone players. When you consider the amount of standalone and portable devices, it's really hard to please everyone. ;)

This forum is about determining how to play video (mostly xvid) on crotchety standalone boxes, so it's a perfect fit. No threads specific to your device, it's mostly set-top boxes, but they all suffer essentially the same problems - and it's very likely the wolverine even uses one of the same decoding chips that are found in set-tops.
