New file format: call for developers

Postby streaming2u » 05 Apr 2010 11:24

Hello,
I would like VLC to support a proprietary video container format.

Is there any developer available for the task? We have budget restrictions on this project, but I have some money for it.
Thank you to anyone interested and sorry if this is OT, won't post again.

BR

Just out of curiosity, what is the new file format going to provide that existing one can't do, or be extended to do? I am asking the question, simply to find out whether you are making the best use of available resources.
Providing logs, messages, configuration info (VLC, OS, Hardware) and a clear explanation of the issue always helps the problem solvers help you, even if they don't end up solving the issue. Just think what you would need if you were solving someone else's problem. Additional: Always looking for eager and capable MacOS X developers to join the VLC team - for more information see here.

Maybe. How much implementation effort is needed? Something like Matroska would take many months, possibly a year to implement. Fortunately, most file formats are a lot simpler.

Hello,
our container format is nothing but an encrypted version of an existing format, so what we really need to do is do:
- get the key
- decrypt the file
- pass it over to vlc for playback.

We've been digging around in the source of VLC and 95% is already there, we just need someone experienced in VLC to join together the pieces and link against our decrypt library. The alternative is for us to learn how VLC works, which we think we'll take us longer.

It's a few days work, really.


Do you know of anyone we can ask to?
Thank you.

If the whole file is ciphered and and a custom header (hopefully with a new magic number at start) is prepended, then it should be relatively easy.

On the other hand, if encryption is tied to the file format, similar to Apple's proprieraty extensions to MPEG4, then it might still be easy, but you'll need to get someone who knows the file format. The author(s) of the relevant VLC plugin may be a good start, though I cannot talk for him/them.

Hello Rémi,
I've contacted two of the authors of the modules that are involved, but got no answer so far.

Anyhow, it's really a piece of cake for anyone with a reasonably good understanding of vlc, would you recommend me someone specific? Thank you for your patience.
