Hi,
I compiled all the latest stuff for the 7D from g3gg0/magic-lantern. I'm not able to get any results from mlv_dump other than a read out of the file structure of the .mlv.
I wonder what it is I'm doing wrong? maybe my usage is incorrect?
Code: [Select]
studio@studio-linux:~/Desktop/MLV_Dump0$ ./mlv_dump /home/studio/Desktop/MLV_Dump0/M02-2157.MLV

Code: [Select]
MLV Dumper v1.0
-----------------

[i] Mode of operation:
   - Input MLV file: '/home/studio/Desktop/MLV_Dump0/M02-2157.MLV'
   - Verify file structure
[i] File /home/studio/Desktop/MLV_Dump0/M02-2157.MLV opened
[i] Processing...
[i] Reached end of chunk 0/1 after 1379 blocks
[i] Processed 603 video frames
[i] Done


So, I searched and found.

In linux type

./mlv_dump -h and get the usage RULES

I'll keep my post so people can see and learn from my own mistakes

When I try mlv2dng.exe I have no problems getting the .dng output.

BTW. I am having no issues recording continuous frames at 16x9 @ 1782. on a 1066x toshiba 16gb.
no pink frames. no small hacks enabled. works great. I compiled these modules for the 7D. file_man, ime_std, ime_rot, xml_cfg, raw_rec, pic_view. Raw_rec works well. Am checking the buffering strategies for speed gains. right now with my card I get upwards of 67 MB/s write speed whilst recording. the card benchmarks avg. 90MB/s.

I did something to my 50D, now I have these .MLV files and am lost in a sea of forum posts.  I'm on Windows.  Can someone point me to where I can get a program/script, whatever, to get me to RAW so I can RAWanizer it :)  I've read just a thing exists, but have also read many problems.  So don't want to download something old and gnarly.  Thanks!  I just hope I can find my way back to this forum thread! :)

check out mlv2dng by gnarr.
https://dl.dropboxusercontent.com/u/3181048/mlv2dng.zip
the program is command line executable on windows something like.
c:> folder/where/mlv2dng.exe c:> file/where/Mxx-xxx1.MLV > c:> folder/where/you/want/xxxxxx.DNG
I make my folder before and drag and drop it onto the DOS prompt window. works good.
mlv_dump, is available from somewhere around here it's linux, but it's got more options (as far as I can tell)
search mlv_dump. or compile it yourself from g3gg0's repository @ bitbucket.org.

Thanks John.  I sent the dev a private note.  Don't see why a C++ person (scripting is all this old dog is useful for anymore) couldn't make a quick Windows command utility to parse MRV into RAW.  Anyway. offered to help.  In the meantime, I put my 50D back to one of Andy's stable builds.

Hey man, mlvdng.exe goes all the way to .dng no need for raw inter. Also, i'm pretty sure g3gg0 put up a mlv_dump.exe I may be wrong. but i would check developer g3gg0 threads.

for 50D I made MLV_REC and raw_rec so the choice is yours. raw_rec is still faster, except if you have a 5DIII.

Thanks for the 50D development! Looking to test out MLV... Wonder how the 50D will handle the extra info??? Thanks for the extra effort.

@dude: the link (in the Assimilate press release) for the Scratch player has been pulled by Assimilate, apparently, but I found the new location:

I sent you a private message and you're now publicly saying I don't take the time to read your work?  That's not very nice.  I've read everything you've wrote.  I can't find a mlv_dump.exe for Windows.   All if you have to do is say it doesn't exist and you don't know when it will, OR, point me to it.  Really, g3gg0! :)

sorry, i read forum and answer there before i check any PMs.


look in the main post and download the pre-built version.
> if you want to test recording, grab my sources from https://bitbucket.org/g3gg0/magic-lantern or use the pre-built ones. (tested on 5D3)

as i update the link when i make new versions, please use the link from the main post.
there is raw2dng.exe, mlv_dump.exe, raw_rec.mo and a few other modules in that zip.
just open the first page, check my post and search for "pre-built". this is a link to the latest version.....

Keep your personal stuff off this board!

If you read this thread you will find this on reply 218:

here is a windows build of mlv_dump

did not test it for 4GiB problems. can someone else try?

and a bit lower you will find this:

I just tried the mlv_dump.exe -o mlv.raw -r m10-2205.mlv

and ....  made the mlv.raw file

and ... drag and drop on raw2dng.exe and Yes!!!!!!!

Got dng files!

So try it and see.  If it is not compatible with current build then wait until dev makes it available.

@g3gg0!

I think the confusion is that you assume someone is going to load your sources and naturally see the utilities, which was natural when you started your effort. 

I ended up with source that creates .MLV, which I didn't realize (and still don't know exactly how that happened).  You might want to edit your first post to make it clear that if someone ends up with MLV files on their camera, that they can download your zip file and get the exe.   Many people like me probably use RAWanizer straight to Cineform to check what they've done, and save on time/space with the whole DNG/TIFF extraction stuff.

I may have missed things, as RenatoPhoto pointed out, but honestly tried very hard.   Again, thanks for all your efforts!

I hate sounding like a broken record... buuut :P
Anyone compiling some tests for 5D2 now that 50D seems to be getting some compiles too :)

Try the 50D one https://bitbucket.org/OtherOnePercent/tragic-lantern-6d/downloads/mlv_rec.mo should work in the 5D2 (at least for testing).

That scratch play looks interesting but ads in the free version? Come on! VLC/MPC doesn't put ads in. Quite insulting to have spyware in your media player.

@dude: If you convert a .raw file (using raw2cdng.exe rather than raw2dng.exe) to CinemaDNG, you can point Scratch to the first .dng file and it will open and play the clip. Pretty cool. Colors are a bit off but Scratch is apparently a huge application, even the player portion, and there's probably a way to insert a LUT somewhere so that the clip will look reasonably like what you shot. Just FYI, haven't played with it for very long. Cheers!

P.S. Not sure anymore where I got raw2cdng.exe, it was on the ML forum somewhere, you should be able to Google it.

well, thats the reason why i pointed out in the main post that one has to convert it to legacy .raw before he can use it in his normal workflow.
i also provided the binaries so one can run the tools without the hassle of cross-compiling.

as this is no release for the masses, i define my assumption to be perfectly fine.
it is for developers, for testers, BUT NOT for productional use yet.
as the board "General Development Discussion" implies, this is yet in development and end users will get a nifty UI, workflow, guide and whatever as soon it is in "New Releases" forum.

i understand that this is not the allround-happy-packet ready for everyone to use which you seem to have expected, but it was never meant to be that.
this will follow as soon this video format and the code is going to be merged into main tree.

@g3gg0

Sorry,  I made it sound like it was your fault, and that's not what I mean.  I meant to say that you might not realize that your code is now seeing its way onto more and more cameras (like my 50d) and that you may want to edit the first page a bit, for people like me who don't know a thing about MLV but now have it on their camera.  Again, I'm sorry if I implied that you had done something wrong.  I realize it was all just a big confusion.  I AM all round happy packet!   Please believe me.  And thank you again.

I can already see how MLV will be a big improvement with the EOS-M.  Right now, I have to pick which mode to clean up the files, normal or crop mode.  With your work, future software can figure that out.  Again, if there is anything I can do to help you with MLV, let me know.  So again, please accept my apologies and thanks!

I'm going to go out on a limb and say that MLV will be better for SD cameras in general... they already only go ~40mb so +/- 1MB won't make a difference. On 50D I struggle with 1920x1038 and 1080P where before I had idle time.
