"MlRawViewer is a cross-platform viewer for raw video files produced by Magic Lantern." and outdated, not supported anymore. Nobody will fix your issue.
Move on to supported applications.

I didn't know it was outdated. What application is people using now?
This one maybe? https://www.magiclantern.fm/forum/index.php?topic=20025.0

Most people prefer running native programs programmed for the OS they are actually running. Don't know if W10's Linux subsystem supports MLV App.
Take your pick among https://www.magiclantern.fm/forum/index.php?board=54.0

And your problem with MLRAWviewer is most likely caused by path length. I suggest to redesign your directory structure if you want to avoid further troubles.

To be fair, Mlrawviewer is not that outdated except for the fact no new version has been released in years, if you wanna play vanilla MLV's it works fine. Also for viewing uncompresssed DNG's it works perfectly.

I use MLrawviewer all the time for reviewing footage, in my opinion it's the most intuitive program for Raw or DNG viewing. Its fast, has a fast WB correction, LUT support and most major Log profiles.

Can also work with other brands DNG outputs.

I cant run MLRawViewer on this Windows 10 Home Laptop I purchased.

Its a cheap HP Laptop with i5 8250u CPU @ 1.60 GHz  1.80 Ghz - a NVidia MX110. 8 GB Ram This computer actually runs 14 bit 1920x1080 Cinamdng's from on Resolve very well! With only two nodes its real-time... That blew my mind. A testament to Davinci.

anyways, I cant get MLRawViewer to run, which I always use to review footage.

Windows error message:

QuoteC:\Program Files (x86)\MlRawViewer_1_4_3\mlrawviewer.exe

The Application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail

I have no idea what this means, online one suggestion for the Side By Side issue was to reinstal Microsoft Visual C++ Redistrabutable XXXX I reinstalled a few.. But Nothing. Any changes or locations this should be on.

Or is it the GPU that is not supported.

Please give me some suggestions.

Ofcourse the alternative is to just use Davinci for reviewing, but I have a good workflow for MLRawViewer being my Review app before Moving/deleting.

I have an issue. It does not export to dng. MOV is ok, but when i start export to dng it only creates a folder and does nothing else. Anybody knows how to fix this?

MlRawViewer is abandoned and doesn't suuport anymore.
For DNG export try MLV App 1.7 or smth like this.

I'm having issues viewing MLV files.
The program shows I have two files inside a folder:

But when I access the folder, I don't see any files:




Hi! I have that issue too in the 1.5 version (for mac) but I think it's related only to MLV files in lossless compressions. When I open a folder with MLV files that weren't shot in lossless raw, in MlRawViewer 1.43, there are the previews.

But honestly I don't think it's a real issue.. I just drag and drop on the MlRawViewer's window the MLV files that I want to review, from the finder folder, to play them...

I know this is an old thread and the MLRawViewer is abandoned now, but I figured I'd share the info I have in case anyone has/makes a fix. It is an open source project, and the alternatives aren't as lightweight...

Anyway, on Windows 10 2H22, after running SxsTrace Trace and SxsTrace Parse, I see the following:
ERROR: Component identity found in manifest does not match the identity of the component requested. Reference is Microsoft.VC90.MFC,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.21022.8".

ERROR: Activation Context generation failed.
End Activation Context Generation.

From that, I installed the x86 version of "Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package MFC Security Update", which allows the app to launch, but it fails to play any mlv files.

Maybe (hopefully) someone else knows how to fix this.

Not a fix, but mpv is free, cross-platform, and can play MLV files.  ffmpeg also has some support.  If you want a GUI, smplayer works for me.

Thanks for the info! mpv just closes and ffplay gives weird a sweeping spectrum-like image. Googling this, it looks like some others had already gone down this path two years ago... [link]

names_are_hard

Oh well, works for me.  The obvious choice of course is to use MLVapp.

I looked into this a bit more, and ffmpeg didn't have support for lossless compressed MLV.  Do uncompressed MLV files play okay for you with ffplay?

I added support for lossless compressed to ffmpeg, and will be submitting the changes upstream.  Will probably take a while before it reaches published builds.

Interesting. I tried playing mlv files long ago with ffmpeg/ffplay but they came out all greenish. Didn´t dig into this matter too much but would be very nice to have it working. I guess it would be easy to test simply exporting a short clip ffmpeg -i input out.mlv

names_are_hard

I suspect the green tint is because they're BGGR, and nobody tried to adjust for white balance.  I would guess this would be fairly easy to add.  Even if you need to do per-cam adjustment, that wouldn't be much harder, ffmpeg extracts the camera name correctly.

For MLV, there's no encoding, only decoding, so your example would not work.

Something that does work, however, is this:
ffmpeg -i 70d_04_high_res.mlv -c:v prores_ks -vf scale=1280:720 test.mov
Transcode to ProRes with resize.  This is faster than realtime with a 3072x1318 source, and should be possible to combine with ffmpegFS.  Realtime preview in DaVinci, etc.  I'd guess that for any raw->raw transcode the white balance doesn't matter.

For playback, to me it makes a lot more sense to improve ffmpeg support than try to do it all ourselves.  There are lots of nice GUIs over ffmpeg already, and we get free transcoding, too!

Thanks a lot! It can be super helpful to review clips if it can decode 3K in real time!  :o
