I've updated the file in the link so osx user try and report back, if now it works.

Hi Scrax, if you're talking about the files here: https://bitbucket.org/600dplus/magic-lantern-things/downloads
unfortunately they're still not working for >2GB

Don't worry about 4gb limit so much... I recorded over 4GB already, haven't had a chance to decode it... I'll probably have to add that patch above to the converter...

lol ok, the only reason I'm interested in it is that the ability to record longer clips is make or break for my application (mkIII on a multirotor). I'll take your word that it's not a problem, I just didn't know the filesystem on CF cards was actually able to record past a limit of  4,294,967,295 bytes.

Thanks for the effort that's going into this, the results are really quite spectacular.

Thinking about it, isn't the 4GB file size a limitation of the FAT32 filesystem? I'm not sure there's any option for longer clips besides opening a new file and continuing the data stream there. raw2dng would obviously need to be updated to work with this scheme. Unless there's something I'm missing?

it's because it's not 64bit, I need to update it.

Ahh ok that explains it, thanks.

what are you using to convert them?

Using raw2dng on osx. After work tonight I can try it on windows and see if it behaves any better or not.

whats up with printing uint64 or long long int with printf? I can cut off the 4gb limit but the indicators are all fucked up.

Also regarding the 4gb cutoff, is it possible that the footer isn't getting properly written when the file is cut off? With any file that hit the limit, I get the 'Error: This ain't a lv_rec RAW file' message when I try to convert it. I have not yet tried pasting a footer onto the file.

Hehe, I got my own question....

Does this work:
printf("var = %llu\n", var);

This was helpful, thank you.
