Just a quick note of an error I get in Lightroom 4 final, and also get in the Lightroom 4.1 release candidate. Immediately that Lightroom attempts to display a video thumbnail in the Library tab, I get a popup:

I'm on Windows 7 64-bit. I have Lightroom 4.1 RC 64-bit and Creative Suite CS5 Master Collection installed. I also have Lightroom 3.6 64-bit, which I haven't yet dared uninstall, as well as Photoshop CS6 64-bit beta (which I installed after the problem in Lightroom was already discovered, so that's not related).

I haven't yet had time to try deactivating all my plugins and programs, then reinstalling CS5 and Lightroom from scratch.

I've done a forum search, and while others seem to have had their share of problems with dynamiclinkmediaserver.exe, none seems to have reported this same issue with it crashing.

Does it happen with a specific video file, or with all video files? What type of video file is causing the problem?

Thanks,
Becky

Interesting, hadn't tried checking different video types, but it is specific to AVI files -- but not from all cameras, only for certain models. I *think* they're all Motion JPEG compressed, offhand, but then so are some of those from the cameras that don't cause a crash.

I get a crash for any video from the following (all videos are straight out of camera, unmodified before import into Lightroom, and play correctly in other apps):

* AVI -- Air Hogs Hawk Eye Blue Sky (r/c plane with built-in video camera)
* AVI -- Pentax K-x
* AVI -- Pentax K-7
* AVI -- Pentax K-5
* AVI -- Olympus E-P2
* AVI -- Olympus E-PL1
* AVI -- vtech Kidizoom 1227 (cheap ruggedized kids camera)

I *don't* get a crash for any of the following:

* AVI -- Fujifilm FinePix A303
* AVI -- Fujifilm FinePix 2600 Zoom
* AVI -- Canon Digital IXUS 850 IS
* AVI -- Canon PowerShot G6
* MOV -- Canon EOS Rebel T2i
* MOV -- Canon EOS 60D
* MOV -- Konica Minolta DiMAGE X50
* MOV -- Minolta DiMAGE Xt
* MOV -- Olympus Stylus 800
* MOV -- Pentax Q
* MP4 -- Sanyo Xacti VPC-HD1
* MP4 -- Sony Alpha DSLR-A560
* MTS -- Panasonic Lumix DMC-ZR3
* MTS -- Sony Alpha SLT-A55V
* MTS -- Sony Alpha DSLR-A560

The crash happens as soon as you open a folder containing video files in the library, using the thumbnail view. It happens even if there aren't currently and video files shown on the screen, so long as there are one or more in the folder.

Hopefully this is detailed-enough to lead you to the cause. :-)

Check your Anti-virus quarantine file and see if anything in the DynamicLinkServer folders was quarantined during install.

Hi Rikk -- Double-checked (I'm using Microsoft Security Essentials on Win 7 64-bit) and nothing was quarantined.

Thanks for the suggestion, though!

Just to add a little more to this topic, I've realized on trying an import that as of Lightroom 4, I can only import a new video from one of the above cameras if I'm quick and a bit tricky. Importing videos from these cameras worked fine with Lightroom 3.6, which I still have installed but don't dare try, since I'm not sure if there have been any changes to the catalogue format.

Once dynamiclinkmediaserver.exe crashes in Lightroom 4.x (including the latest 4.1 RC2), video importing no longer works. (I get an error message for every video file in the import, when the import is summarized.)

There's a workaround, but it's sneaky. I have to get the import set up (acknowledging the dynamiclinkmediaserver.exe crash at the relevant point), then browse to a folder that doesn't contain any videos from the affected cameras. Then I close and restart Lightroom.

If I then go to start an import of affected videos, it will allow me to do so if I click import before it manages to thumbnail any videos. (Ie. there's no time to change import options, but those are remembered from my last import attempt.)

Once the import starts, I immediately browse to a folder with no videos from the affected cameras (to get away from the current import folder, as otherwise once the first video is shown on importing, dynamiclinkmediaserver.exe crashes taking Lightroom along with it, and the whole import fails). I also hit Shift-Tab to hide the panels at the edges of the screen, just to be on the safe side. (I'm guessing rendering of the thumbnails for the import along the bottom of the screen might also cause a crash, but haven't tried leaving that bar active to see. ;-)

I've just tried this and successfully imported 37 videos from one of the affected cameras without dynamiclinkmediaserver.exe or Lightroom crashing. (Well, obviously dynamiclinkmediaserver.exe crashes when I try to browse to the relevant folder after the successful import, but at least I don't have a huge number of videos building up waiting for me to add them to my catalogue, while I wait for a fix.)

I share this info in the hopes of helping anybody else who happens to have the same problem. Becky contacted me outside the forum the Wednesday before last to request some logs, which I've provided, so hopefully I'll be able to get a resolution in the not-too-distant future. (Becky, please let me know if by any chance you didn't receive the logs.)

I have the same problem. Running on Windows Vista 64 bit. The problem is tragic, but the lack of customer support is inexcusable!! Seems there is only support for installing...not caring that the installed product doesn't work!!!

I have occasionally got it to work by stopping dynamiclinkmediaserver.exe and rebooting. But that was only a couple times, and most the time it doesn't fix it. I checked my anti-virus software Kaspersky...nothing was quarantined during installation. I uninstalled the software and tried downloading it again...Adobe wouldn't let me. I had to re-install with the software I originally downloaded.

At this point, unless there is a solution very quickly, I'm inclined to get a refund and stick with version 2.7. Granted, the new tools in 4.1 are great...but not worth the money for the hassle. 4.1 is also much slower...hmmmmm.

I also have this problem, in the exact same way as the original poster. I'm using Windows 7 64bit. The only way that I can avoid it is by making absolutely sure there are no video files in the directory or subdirectories that I am importing (which makes the import process nearly useless). Help please!

Just a reminder this is a symptom that can be caused by a virus scanner quarantining a file or two. Try a re installation with your Virus Scanner unplugged...

I can't speak for Jared, but in my own case and apparently that of William as well, the virus scanner is not in any way related to the problem. No files were quarantined on installation of the program (in fact, I don't believe I've ever had a single file quarantined since I switched to my current PC 18 months ago)...

When I last heard from Becky at Adobe, she seemed to believe it was related to missing or corrupted codecs in Windows itself, and requested some logs from me, which I provided very shortly thereafter. Unfortunately she's not had a chance to get back to me in the last few weeks, so I can't say for sure if there's a way to fix this beyond the rather extreme suggestion that reinstalling Windows from scratch might help.

Keep in mind that some scanners will quarantine files well after installation and you might not have noticed. Have you tried a LR reinstall?

Nothing has been quarantined or detected by my scanner (I just checked; it is also set not to delete anything, to retain quarantined files permanently until I manually delete them, and to log all detections).

I've not had time to try a reinstall yet, of Lightroom *or* Windows.

It is 100% not related to any virus scanning on my system. I've looked through and tried all of the "fixes" I've found listed online (in this forum and others) and none have worked for my situation.

However I do have one question: Is Quicktime absolutely required to run Lightroom 4? If so, then that may very well be the genesis of my problem. I loathe QT quite possibly more than I loathe any Norton product, and will do everything in my power to prevent it from being installed on my system. I didn't see any requirement that it be installed for LR4 to work correctly, although I may have missed that.

Honestly, I don't care about video within LR. I have no need for video import, and would just as soon turn it off if I can. I just want to be able to import photos without the application crashing when it discovers video files in the same folder as photo files.

So even if I have to turn off video functionality within LR4, that's fine. But having a functional application is the first priority.

Adobe....any progress on this issue?

Jared,

You are running RC2 and you have reinstalled?

Just pinging this topic again to see if there's any progress.

@Becky Sowada, can you please confirm you received the requested logs? I still experience this issue on the latest version 4.3.

Just figured I'd ping this topic again, given that two years later, the problem *still* exists in Lightroom 5.4.

I never heard back from Becky after sending dxdiag logs as requested, so I'm no closer to a solution myself and simply have to avoid browsing to folders containing video from any of the cameras I listed previously.

And like that, I stumbled into the answer myself, after doing some digging with Process Explorer. Whose software is to blame, I don't know, but the answer is that Adobe's software doesn't play nice with that from Blackmagic Design.

If the Blackmagic Desktop Video package I received with my Blackmagic Intensity Shuttle is installed, I get this crash from dynamiclinkmediaserver.exe repeatably, 100% of the time, every time when I browse a folder containing MotionJPEG video from at least the following cameras (and probably more):

* AVI -- Air Hogs Hawk Eye Blue Sky (r/c plane with built-in video camera)
* AVI -- Pentax K-x
* AVI -- Pentax K-7
* AVI -- Pentax K-5
* AVI -- Olympus E-P2
* AVI -- Olympus E-PL1
* AVI -- vtech Kidizoom 1227 (cheap ruggedized kids camera)

MotionJPEG video from certain other cameras, though, is not a problem. If I uninstall BlackMagic's software, Lightroom shows and plays videos from the above cameras just fine.

I have tried updating to the latest Blackmagic Desktop Video 10.1 for Windows release as well as the latest 64-bit Lightroom 5.4 [955652] (aka Lightroom 5.4.0.10 if I check the version of the executable), and the problem still exists.

I will also report this problem to Blackmagic, and direct them to this support thread.

The problem has now been reported directly to Blackmagic. Unfortunately, they don't have an official, public forum, so there's no thread I can cross-reference. If this problem has occurred for you too and you own Blackmagic hardware/software, I would suggest also reporting it to them directly.

As a temporary workaround, instead of uninstalling Blackmagic's entire app, you can rename BMDCodecMJPG64.dll in the Blackmagic program directory. (If you're not using Lightroom 64-bit, you may need to rename the version without 64 in the filename, but for me on a 64-bit system, just this file was enough to resolve the problem for me.)

Of course, renaming that file could cause problems for you in the Blackmagic software. I've not tried troubleshooting that to see if it works OK without the file, but it seems unlikely it would be there if the app 100% worked without it present.

I would hold out hope that Adobe will liase with Blackmagic to resolve this issue more permanently for their users, though!
