MLVFS - a FUSE based, "on the fly" MLV to CDNG converter

[mothaibaphoto]

Am I the first one who really tried?
Dokany installed. I see mounter.exe process launched from Dokany install dir.
Here is my attempts to launch mlvfs:

If I try to start the exe with all requered params it just exits silently:(

[surami]

Is the MLVFS folder at the path and environment variables?

[mothaibaphoto]

@surami: It makes me wonder, why, but I tried with no difference. Did you get it working this way? If no, please, don't advice just guessing.

[surami]

@mothaibaphoto: Sorry, I just guessed. I can't get it working till now, let's wait for a pro...

mlvfs <mount point> --mlv_dir=<directory with MLV files>
for windows there is only the possibility to mount as drive, so the path must be a drive letter

e.g.
mlvfs x: --mlv-dir=d:\raw
to mount on X:


edit:
clarified my post, didnt see that you've tried to mount into a dir.

[mothaibaphoto]

Great, it works!!! Thanks to g3gg0, MLVFS for us, windowsers just around the corner !!!
Issues:
1. I can browse with explorer, but Bridge prompts that there is no free space on disc. If enter to folder with Bridge anyway, mlvfs.exe crashes:

And Resolve crashes mlvfs.exe too, without promps.

2. If I try to open http://localhost:8000/ I get messages in cmd window with started mlvfs:

Page in browser stays empty.
I tried AE too: it imports and renders without problems...

For windows version Web based GUI works but strangely all fields in "Configuration Options" are empty or not checked. If you try to check any radio button the "Configuration Options" table looses it's last three lines (e.g. "Interpolation" and below, same in firefox, internet explorer and microsoft edge). Refreshing page gives all blank fields again. MLV files info is working, previews are working as well.

So the paratemets can not be changed from the web I guess. Did not try from CLI switches though.

Thanx for the great solution for ml raw editing

@mothaibaphoto:
i am using it on a folder with a dozen of faulty, old, new and weird MLVs without any crash or (unexpected) error.
but i am only using the windows explorer and picture viewer.

can you nail it down to either a specific MLV file that causes trouble or the tool that raises that errors?
maybe its a combination of two things, idk

you can add the option -d to mlvfs to show a debug log, please post/upload one when it's crashing.

It's a fresh and correct MLVs shot with last MKIII build, non-crop mode, nothing special. Windows explorer and even Adobe AE works flawlessly for me too. Here is what happens with Bridge:

What browser? IE? I noticed this too, there's something wrong with the jquery that reads the initial values, it still works to set the values of options though. The last three options are actually supposed to be hidden unless dual ISO is turned on, since they only apply to dual ISO.

Does it work with other browsers?

@g3gg0
I actually managed to mount into an empty directory (Win7 x86 VM)

@mothaibaphoto
You need to start MLVFS from the directory it's in (cd to mlvfs.exe dir before launching it) so it can find it's support files. That's why the webgui is blank.

I suspect I did something dumb
Ok, now webgui behaves exactly as @bouncyball described with Firefox and MSIE.
Command-line parameters seems works - I successfully tested --stripes on file with vertical stripes.
It's possible to open files one by one.
Attempt to select all files and copy to another disc - crashes mlvfs.exe, such as Bridge and Resolve.

[g3gg0]

@dmilligan:
repeated copying several times, worked properly for a while. selectively copying files is fine.

after maybe about 2k DNGs i got:
build_index: fopen error: Too many open files

so there is something troublesome indeed.

[g3gg0]

ok think i've found the reason.
it doesnt always close chunks. prepared a patch.

[g3gg0]

@dmilligan:
https://bitbucket.org/g3gg0/mlvfs/commits/48aa2f6f7434df7bdf05b33b33d1e6fe5621b8fb
https://bitbucket.org/g3gg0/mlvfs/commits/a6602a4b9cf649cfa58db3bc1db6e86946430e9c

those two address some issues that cause the mlvfs.exe to crash.
e.g. the .gif reading crashed in a reproducable manner when offsets were beyond end and debugging was enabled.
so i also sanitized parameters in .dng reading.

it also adds a lot of checks to malloc'ed areas to play safe.
i hope it will fix the reported problems.


still i am wondering how it will free allocated image buffers.
the memory footprint raises slowly but continuously when copying files.
memory is allocated via get_or_create_image_buffer and never free'd.

[g3gg0]

ah shiiit. VS doesnt take the indentation the project uses by default...
will fix.

thats the fixed version:

[g3gg0]

for those who want to try: mlvfs.exe

[bouncyball]

@dmilligan
the problem shows up in every browser: firefox, msie, chrome, microsoft edge.

[dmilligan]

@g3gg0

Image buffers should be getting marked when the file is closed and then disposed when new image buffers are needed. I recently changed some of this behavior so there may be some issues. All this code is rather convoluted b/c we try to be efficient as possible. For example if some program opens a file, reads part of it, closes it and then opens it again, we don't want to have to reprocess the frame, so we try to to be smart about keeping processed frames around for a bit after being closed. MLVFS was much simpler and efficient when we could just process the requested section of the file, but now we have processing options that need to process the whole frame at once (decompression, dual ISO, etc).

[g3gg0]

yeah, makes sense and fits to what ive seen.

proposal:
check if image buffers that are already allocated > x MiB and free the oldest ones to get < y MiB
every buffer has an age field (timestamp of the last access using time()? or some counter?)

[mothaibaphoto]

With last exe browsed some folders with Bridge(!!!), than run Resolve ... and get smiley bsod never seen before...

[g3gg0]

no troubles here with LR

but when stumbling through the code, i found another thing that can be troublesome.
can you redownload the mlvfs.exe from the last link and try if its better?

[dmilligan]

proposal:

I've cleaned up and simplified that code quite a bit. Since its a linked list we just delete from the beginning of the list and add on to the end, so the oldest buffers are always at the beginning. Haven't verified that there aren't any leaks, so there could still be some, or leaks from other places.

Just curious, which version of dokany are you compiling against? I was using 0.8.0 and provided links for that version. Just want to make sure we're on the same page.

[g3gg0]

yeah it's the oldest one, but is it also the LRU one? hehe.

right, i am using 0.8.0

[dmilligan]

Yeah I know, but vast majority of the time programs access frame sequentially. I think KISS applies.

[g3gg0]

ok
