Hi All,

Does anybody know, where I can get a specification for DivX Media Format?

All I can find is a mention that it's based on AVI/RIFF.

Thanks in advance,
Al

Well, that SDK file does

Well, that SDK file does provide documentation but not for the file format specification if you were looking to code your own file handling functions in a programming language such as C++.

Can any of the divx developers provide a linux version of the binaries in the SDK mentioned above? Or supply the technical documentation on how to modify the avi format to make it .divx compliant. Seeing that you have chosen .mkv as a new format then I not sure how it could hurt by revealing the technical specs at this point.

My purpose is just to write a c++ command line program for doing exactly what DivxMux.exe does but natively in linux. This could also be released as a library for adoption by encoding suites ex. avidemux.

Cheers!

DMF 2 SDK

Have you guys seen this SDK for DivX Media Format (.divx)?

http://download.divx.com/labs/DivXMediaFormat_SDK_r2.rar

What's the use case you're going for? Are you trying to build your own mux?

I showed this to the VideoLAN

I showed this to the VideoLAN guys, and they said that the specification description is useless because the file descriptor is missing.

Is there any way to get the real specs for DMF (with the file descriptor)?

So that an open source full implementation of DMF (or at least the parts of it not related to the video on demand service) is possible?

DivX/DMF is touted as an open format (in contrast to Quicktime and WMV) so i hope you guys live up to the promise, and that those "open format" promises you once made weren't weasel words.

I have the same trouble. Is this open source specification?
