Default playing divx movies on a slow slow computer

sponsored links

i have a pretty respectible computer i'm making divx movies with.
But once in a while i like to play the movies on my slow 233mhz laptop.
But guess what? It plays them very choppy.

Is there a special setting to the divx5 codec where i can still get the nice quality but also make it easy to read for a slow computer without the chop chop?

On a 233mhz, there's no way you can play a high bitrate encoded divx movie. You can however lower the quality slider bar under the video divx5 properties and also use a low cpu intensive player to play it, but I seriously doubt this will make much of an improvement.

Divx is just not meant for a slow computer. At the very least, a 350mhz to play divx311 content. Even higher if you play divx5.

Make sure that you have such features as bframes, qpel, etc. disabled as the increase the amount of power required for playback.

As said make sure that post processing is disabled, also that the files are low res/bitrate.

You might also want to try ffdshow for playback instead of the divx5 decoder. You might even try the XviD decoder.

All the above may still not help enough though...

Well, my laptop is really not that bad. It's almost playing the divx5 files. A little bit of choppiness but not that notisable. The chop really comes when i fastforward or something like that

Can you tell me about ffdshow and Xvid a bit?
Are they players that use less CPU?
I'm using Gdivx right now - it works better than divx alpha...

ffdshow is a DirectShow decoding filter for decompressing DIVX movies. It uses libavcodec from ffmpeg project for video decompression, postprocessing code from mplayer to enhance visual quality of low bitrate movies, and is based on original DirectShow filter from XviD, which is GPL'ed educational implementation of MPEG4 encoder.

- fast video decompression using optimized MMX, SSE and 3DNow! code
- support for different codecs: XviD and all DIVX versions
- image postprocessing for higher playback quality
- automatic quality control: automatically reduces postprocessing level when CPU load is high
- hue, saturation and luminance correction
- experimental sharpening filter
- noising (of course if you want it)
- presets
- completely free software: ffdshow is distributed under GP

Of course you could have just looked that up on it's homepage.

What is XviD?

XviD is an ISO MPEG-4 compliant video codec. It's no product, it's an open source project which is developed and maintained by lots of people from all over the world.

The XviD decoder "should" be able to decode DivX5 content... Possibly with lower CPU usage. It can definaltly playback DivX5 content not using advanced features, which as i said above you should avoid.

now, the ffdshow is not an actual player. I downloaded it, and it installed dll codec files i beleive.
Are they integrated into gdivx for example?
What i'm saying is - when i play a divx movie, will it use those new and improved codecs from the ffdshow i install?

I think the answer is yes because I'm playing a pretty nice quality avi movie on my laptop now after installing ffdshow FULLSCREEN from the cdrom drive!!!! Usually i would be able to play the movie this well even from the hard drive!!!
Am I imagining?
