OGG/WMA with DivX?

[Malfeasance]

I've just been getting into encoding for my Pocket PC lately as I'm still only about half a year into the Pocket PC scene. Before things weren't an issue with my desktop, but with much less space avaliable to me on my Pocket PC I find myself cutting corners everywhere I can to save some space. Before I would use mp3 for my CD ripping and such on my desktop, it was standard and did the job just fine, space wasn't a big deal. But now I check more into audio codec and find that WMA and OGG can give me the same quality at roughly half the size. That's a pretty nice cut back for me, and have been testing between the three to see which I'll go with. I'm leaning more with OGG currently, but I hear it's performance on PocketMVP isn't that great (I just don't like having multiple players for the same task, and PocketMVP runs video far better then anything else I've found).

I've been encoding my divx from a tutorial I found when researching. Each time the person encodes the audio portion of the divx in mp3, mono, around 32kbps. Now I figure that if OGG and WMA can offer the same performance at less space consumption, why not go with that? Is it something in the codec that requires mp3 or does ogg take to much processing power to render the video well? Or is it possible, just not supported by any player? It seems odd to me to stick with the mp3 format for divx encoding if wma or ogg can offer the same quality with less space. I'm sure there is some tech reason that I just don't know, so that's what I'm trying to find out. Thanks in advance.

Just for playing audio, I encode to WMA. For music, it sounds fine. Doesn't do so well with other sounds though. If you want WMA in your videos, however, you'll need to encode in WMV too -- WMP is the only player that supports WMA audio in video currently.

OGG takes more resources, yes, and doesn't seem to get along with the standard AVI container either. Which is why we use MP3 to encode our DivX AVI's.

Enter OGM containers. They require a few steps more than you're already taking to make DivX videos, but it will merge DivX with multiple OGG tracks if you like (ie. you can do a DVD with multiple languages, or get the commentary track) and can encode in chapters (ever wonder what the File->Chapters menu in PocketMVP was for? :wink: ). At this early point in the game though, the catch is that since OGG uses its fair share of resources, as does DivX, you have to pay more attention to your screen size, framerate, and bitrate or you'll start dropping a lot of frames.

Well I like my DVDs in Wide screen, so I rarely come across something in full screen. In fact, I think the only DVD I have in full screen is my Transformers ones. I've been playing with a Lord of the Rings clip to adjust bitrate, frames, and such for performance. I've been using 250 bitrate with about 25 frames and have been pleased with the results. My Fellowship of the Ring resoultion is at 320w X 136h. It would be great to use chapters for movies especailly the longer ones. Is there a way to use chapters with using mp3 for the audio over multiple ogg tracks? I would have to have to cut down my bitrate, frames, and such to spare more power for ogg files. Since I'm using a 1910 iPAQ for my media needs I'm not to strong on the processing power end, but man is that screen pretty. :mrgreen:

I've actually just recently updated PocketMVP, I don't think the version I had before had supported chapters. Maybe I'm mistaken though. I was out of the loop with updating my software for quite some time, but after playing Age of Empires and seeing how beautifully it made the jump to PPC I've been on a rampage to get every last bit of media performance I can out of the little 1910.
