Just as the title says. I'm fairly curious as to how I could go about it _without_ extracting the x264 stream from the container itself.

As additional information ; I'm on a linux system with all the available tools that would imply.

I'd appreciate any pointers I could get!

Uhm, I've looked at it. It's not what im looking for. I'm was hoping to do it without any such custom tools.

And it's gtk 1.2 which is god knows how old. Not even compiled in
on my system as there is no use for it. And from what i can tell it
does infact extracts parts or the entire stream to get the x264 stream header information.

without extracting ? mmh, depends on what you want to know.

The more appropriate materials might be mkvtoolnix/mmg or FFmpeg sources...

Well I want to know the encoding options of the x264 video stream inside the mkv.

I already know how i can go about this by extracting the video stream. But it would be very nice to go about this without the rather large space/time overhead extracting the stream itself creates.

And as I said earlier on I'm on linux so the tools available to do parsing of any kind is quite good. I've tried some myself but I have not been successful, which is why I'm asking for some help :)
