about the "NUT open Container Format"

[Yong]

Where can i find the informations about NUT open Container Format, thier muxing tools or splitter?

[RadicalEd]

Currently NUT only exists as part of libavformat in FFMPEG, AFAIK.

Any specs?

Search the mplayer-dev-eng mailing list archives for 'nut' and 'specs' ....

Its a great container with a focus on extremely low overhead and very low CPU consumption for parsing ( typical Linux doctrines ;) ). There are not many tools supporting it right now, but you can play NUT files fine with mplayer, even the win32 version, and FFMPEG contains a NUT muxer AFAIK.

I hope nobody minds me saying that, but there is something i would like to add here about NUT and us. When the first matroska specs draft ( MCF that time ) was ready, we were asking the mplayer dev team about some comments. They found it bloated and too Windows centric, and NUT's birth can also be seen as their answer to our Windows crap ;), coded by ( quote )'.. stupid DirectShow kiddies ...'( unquote ).

As you might know, MKV files already have a lower overhead than most other containers we know, and our focus was more to have a feature rich container with menues and a nice tagging system, as well as excellent editability. We never understood why the mplayer guys thought we are wanting too much ( = bloated ), and invested so much time and effort into a new project, instead of adapting matroska for their needs ( EBML would easily allow to do that ).

That time communication between them and us wasnt really nice, especially because one of their team members was obviously missing all the classes about politeness and a normal, human way of discussion in shool and before, and we were finally sick and tired of being insulted repeatedly for the decision to code our main library in C++, instead of C .

Today we are having a kind of normal relationship again, but to be honest, this is mainly the case because the mplayer team has stopped trying to make fools of us, for obvious reasons :D. The whole matroska team is proud about the fact that our 'bloated' project has been supported in so many different apps meanwhile, and on so many different platforms , while NUT has never been truely supported outside the mplayer team, and until today mainly on Linux.

Sorry for the OT talk, but i thought some people might be interested in some background information about the mutual relationship between NUT and matroska ;) ....

If you read C this will give you some info:
http://www.mplayerhq.hu/DOCS/tech/mpcf.txt

As ChristianHJW suggested the mplayer mailing lists should contain more information.

Thanks for the information and explaination.;)
New question here,
Can i use this ffmpeg (http://www.cbu.edu/~nwebb/ac3.html) enoder to trascode avi to NUT container?
The NUT file seems can't play in the mplayer or MPC,mplayer cant play at all; MPC just display the first video frame and pause at the first frame...:(

Remember that the NUT specs aren't finished yet before putting anything into it. That's also why no player currently supports it.

hm i think there were some more docs pointed to in this forum already, but i didnt find the links by using search :(

But MPC have one splitter for it.

@bond,
I'll find it someday, Thanks!

Which implements an older version of the specs. Haven't you wondered why MPC only displays the first frame?

[Yong]

Oh, i just want to test this splitter and container only.:)

[Mark0]

Sorry to revive an old tread.

Anyone can point me to some place where download same file in NUT format? Even samples/test should do the job.

Thanks,
Bye!

It's not done yet, the specs are not finished, only ffmpeg can create such files, there are no samples, you wouldn't be able to play them back even if there were samples.
