This is a message for the Nokia people.
Since you have 3gp codec/controller plugins for the Symbain MMF on all of your phone, I can only assume you have the code already written.
I can't understand why you don't compile it for the Emulator running on windows. I know I'm not the only one who encountered problems in developing apps with video playing/recording capabilities. Having to do all debuging on the phone is a major slowdown of developing time.
This issue isn't only for .3gp file specifically, but any codecs you already have written the code for anyway. You can supply the appropriate DLL for the emulator and make our life easier. This, ultimately, will give the end user (your customers) a better experience using Symbian products and Nokia phones. Since I assume it's all about making this platform the dominator of the market, it's better for you as well to help us cut developing time.
While we are at that, is there any chace of getting some serious documentation for the MMF. It's quite impossible to develope anything using low-level APIs.
Thanx a lot, and hope to hear from you,
