cool.
just out of curiosity. how close to dv is dvcpro hd/100? just a
difference in resolutions, bitrate and 4:2:2 subsampling or also
other stuff?

Can be unzipped with unzip. It creates a directory, which
contains an xml
file and one mxf file for each A/V stream. If I interpret the
xml correctly,
and the MXFs are clip-wrapped, this can be decoded even without
an MXF
demuxer because the xml file already contains the start offset
of the
Data, the video codec and and the size. That's enough to fire up
a raw-dv
parser.
Indeed, this is also the case for the P2 samples that I have, I guess
this will make an implementation quite easy, I think I can do a tiny
utility to copy the contents into a raw DV file, this should make it
easier for existing software to handle the footage, I guess.
Ok, this was easy enough.
The following tool will extract the video data out of an MXF Project,
and dump those into a file raw.dv. It does not do anything to the
audio.

If you use the DVCPRO50 codec, the file should work with a
sufficiently recent version of ffmpeg.
If you manage to apply the patch that I linked in this thread, you
should even be able to work with DVCPRO HD footage in ffmpeg, altough
I haven't tried it.
The included README says:
-----8<--------------------------
This is a trivial utility that extracts the raw dv data from P2 MXF
Cards.
it is very simple and does not do many sanity checks, use at your
own risk.
you call the program with 2 arguments:
1: The /please/use/your/path/CONTENT/CLIP/blabla.XML argument
specifies the xml file of the video
you want to extract
2: the second argument gives the path to the P2 Project:
/please/use/your/path/CONTENT/
The utility will create a file called "raw.dv" in the current folder.
Thats all.
Cheers
