It couldn't run on win7 64bit....
when I run this program ,there is a black cmd windows flash then miss...


it said:

 usage:
mlv2dng.exe file.mlv[prefix]

=> will creat prefix000000.dng,prefix000001.dng and so on

[vnguyen972]

I've been unable to make use of "prefix". Everytime I tried, it just crashed. I'm using Windows version on win8 64bit.
It worked fine without "prefix" but I'd like to have prefix on the DNGs filename instead of just "numbers".

I tried many times after it crashed and it still works. Without the "prefix" sometimes it crashed but it worked after a retry.

Any one could help me out?
Thanks.

Hi guys!
I released a GUI MLV Converter for MacOSX

https://dl.dropboxusercontent.com/u/8769684/MLVConverter.app.zip

However, this version is very poor.
This converter has only function that convert plural .MLV sources at a time.
And this Converter does not have even a combination function for the present.

Please use this Converter if you want to handle plural files easily.

8-beeeaaat!!!

Thank you so much sir!!!!
I will send some smoking hot girls to your house right away

TIP: I achieved to decode a "corrupted" file using the Windows XP 3 compatibility mode. (Windows 8 x64)

[JCBEos]

Once again, got 2 files I can't decode :/

I'll upload them if I can't get the job done.

I tried to see if there's something wrong in the file structure with a hex editor, but nothing seems weird.

i quote myself again regarding corrupted mlv files.

 - what happens?  - some error message?

the program crash, i posted the windows error message here
http://www.magiclantern.fm/forum/index.php?topic=7802.msg75833#msg75833

 - what does mlv_dump say?

where can I download the mlv_dump.exe file? haven't found a good link here
http://www.magiclantern.fm/forum/index.php?topic=7122.0

 - can you convert it to legacy raw?

sorry but what do you mean? (  )


 - what does the mlv player say?

the one on the camera? or your "MLV Viewer"?
MLV viewer is crashing trying to open the file.

 - where can i download the corrupted files?

do you got a place where I can upload two 3gigs files?
Or maybe i can directly upload them to you using a .torrent or something else (got a 100mb/s symetric bandwith)


Thanks in advance, and sorry for the lack of provided infos 

[JCBEos]

Ok so I turned my brain "ON" and did some search....

I acheived to decode one of the two files with mlv_dump

but for the other one...

[g3gg0]

yeah this file is corrupted - it stops somewhere in the middle of data.
seems some part of it is missing.

run the same command, just without -r to dump its content into the output file in MLV mode (name it blah.mlv)
then you can process it using mlv2dng

[artrepublican]

After using this converter: https://dl.dropboxusercontent.com/u/8769684/MLVConverter.app.zip
on osx lion, I can not convert mlv to dng any more. It just make an empty folder.
Anybody know how can I fix that?

Ok so it seems to work, but it output a 1ko raw file :/

uhm when directly converting to raw, you get the message about "in the middle" and when
writing to mlv, it just doesnt output any image?

I recorded a couple of clips in MLV format today and I can play them in MLV viewer, but colors are wrong, highlights clipped. I cannot convert them in MLV2DNG.

Message "unknown header "styl"". My camera is in polish, can it affect this? Styl instead of "style"? like picture style?

Some clips cause the program to shutdown, some go through when on card, some only copied to HDD. One file works from card, then stops working from hddd.

They go through even without the header.

I tried mlv_dump, but it says that file ends in the middle of the block. I cannot convert them to legacy RAW.

can you give some more details about how this file was created?
can i download it?
how big is it?

[Mkolaj]

I don't have it anymore, but will try to recreate the problem.

It was about 3GB in size. I just used mlv_rec module, manual lens (Helios 44), iso 100. It looked like no problems while recording, but I was using global draw with buffer graph.

I've got the same issue on 60D (also Polish language).

Is there a working GUI version for mac? If not, can somebody provide a step by step guide on how to use the script?

[g3gg0]

gnarr, still around there?

[swinxx]

[g3gg0]

it seems this project is cancelled.
so i added dng support to mlv_dump. there is also a mac-os build around somewhere.
