1. Will Dashcam Viewer work with my dashcam?
The only models I have tested against are listed on the dashcamviewer.com home page. Other models may or may not work.
If your dashcam movies do not play in DCV or you don’t see any GPS data displayed, I may be able to make it work — if you help me. You’ll need to send me a ‘clone’ or zip of your camera’s SD card disk image. The clone should contain at least 3 movies and associated GPS data files.
Some dashcams use separate files for the videos and the GPS data. In that case, the file/folder structure of the clone must be preserved. For example, the Mini 0801 stores its movie and GPS data like so:
SD Card |--- DCIM |--- 100MEDIA |--- AMBA0462.MOV |--- AMBA0463.MOV |--- MISC |--- gps |--- gps0462.log |--- gps0463.log
Zip a copy of the entire SD Card folder. Also, please provide your dashcam’s firmware version. You can send me the zip via https://wetransfer.com. My email is firstname.lastname@example.org.
2. How do I register the software? Is this a one-time payment?
You first purchase a license using the PayPal links on the home page. Within 24 hours (usually a lot quicker) you will receive a personalized registration code. You enter the code into the Dashcam Viewer program. Click here for more info or watch the registration video.
A common question I hear is: “Is this a one-time payment or will I have to purchase a yearly subscription?” I personally despise subscription-ware! Since version 1.0 was released in 2016, I’ve provided free updates for everyone and I have no plan to change this policy.
3. [Windows] When I run Dashcam Viewer I don’t see any of the program’s windows but the Dashcam Viewer icon appears in the Task Bar.
If you’ve recently changed your monitor resolution or screen configuration, Dashcam Viewer may be drawing the windows offscreen. Try this “hard reset” procedure, I think it will fix it:
- Quit Dashcam Viewer
- Hold down the Shift key
- Start Dashcam Viewer
- You will see a dialog box come up asking if you’d like to Reset All Settings. Click “Yes”.
Now all your windows should appear onscreen.
4. What are some best practices for running Dashcam Viewer?
Here are some tips for getting the most out of Dashcam Viewer. I’ll add to this list as time goes on:
- If Dashcam Viewer’s windows don’t appear onscreen, see the reset procedure above.
- For best video exporting experience, replace the LGPL version of ffmpeg with the GPL version as described below.
- Simultaneous playback of multiple videos while updating maps and widgets can be CPU-intensive. If video playback appears to stutter, or Dashcam Viewer issues the error “Time out has occurred while trying to load file…”, you can try the following:
- Use a fast, high-quality, USB3 SD card reader if your Mac/PC doesn’t have have an internal SD card slot.
- Copy the video folder from your SD card to your internal hard drive. Then load the videos from the hard drive.
- Change your dash cam’s settings to produce lower-resolution videos.
- Set your dash cam to record videos no longer than 5 minutes each.
- When you load your videos from the SD card everything works fine, but if you copy them to a folder on your hard drive and load them from there suddenly the Map, Graphs, and Dashboard no longer display GPS data. This can be caused by an extraneous folder named “GPS” or “gps” in the video folder. If you dashcam doesn’t create a “GPS” folder, make sure you don’t add one to directory containing the videos or Dashcam Viewer will get confused.
- If you’re running Windows and Dashcam Viewer playback is slow or stuttering, try re-installing the K-Lite Codec Pack and experimenting with the tick boxes in the Advanced Options. Users have reported improved playback performance by tweaking the options.
- If no GPS data is displayed, the problem could be that your files are on a Network Storage Device (NAS)If Dashcam Viewer can’t seem
5. When I use Dashcam Viewer to export a video clip from my dual-channel dashcam, how come I don’t get a picture-in-picture video as a result?
Dashcam Viewer ships with the LGPL version of FFmpeg. The LGPL version will only export the front channel to your videoclip when you choose the Export Video option. The solution is to replace the LGPL version of FFmpeg with the GPL version off the internet. You can download the Mac GPL ffmpeg here and the Windows GPL ffmpeg here.
Mac GPL ffmpeg installation: The GPL Mac FFmpeg download comes as a zip file. Select the most recent ffmpeg .zip file (not the .zip.sig file) and download it. On newer macOSs, applications downloaded from the internet need to be verified the first time they are run. To do this, immediately right-click on the ffmpeg icon and choose Open. You should see a dialog that looks like this:Click “Open” and it will run in the Terminal and immediately quit. Now you are ready to replace the old version as follows:
- Right-click on the Dashcam Viewer icon and select Show Package Contents. This will open the contents in a new window:
- Open the Contents/MacOS You will see the LGPL version of ffmpeg. Move it to a safe location outside of the package.
- Now move the GPL version of ffmpeginto the MacOS folder. Close the package window and you’re good to go!
Windows GPL ffmpeg installation: Download the latest ffmpeg zip file. Unnzip the ffmpeg package and copy the ffmpeg.exe (located in the bin directory) to the Dashcam Viewer directory. You will be asked if you want to replace the existing ffmpeg.exe. Click Yes. That’s it.
One caveat. Since each version of Dashcam Viewer ships with the LGPL version, you will need to repeat this process every time you update Dashcam Viewer.
6. Why doesn’t Dashcam Viewer play the .TS files from my INNOVV K2?
TS format is not supported in Dashcam Viewer. MP4 will work fine, though. MP4 is much more common and more compatible with video software. You can change the format to MP4 in your INNOVV K2’s settings.
7. When I play videos from my Viofo A129 Pro or A129 Pro Duo on my Mac they appear to stutter. Why?
For some unknown reason the A129 Pro’s MP4 encoder produces video files that skip when played on a Mac using Quicktime Player or Dashcam Viewer. No workaround at this time so this dashcam model is not on the supported list for Mac. This does not appear to be a problem on Windows.
8. Why doesn’t Dashcam Viewer work with the Rexing V1P Pro?
Although Dashcam Viewer works with the Rexing V1LG and V1P, the latest firmware of the V1P Pro and V1P (Gen3) was written such that the vehicle’s latitude and longitude waypoints are now encoded in a proprietary format that I haven’t seen before. Two V1P Pro owners have contacted Rexing to request the data encoding scheme, but Rexing has refused to provide assistance. So unless Rexing agrees to provide the encoding scheme or I ‘crack’ the encoding, I’m afraid I won’t be able to support the V1P Pro or Gen3. I suggest contacting Rexing on this issue. There’s power in numbers.
9. After I download the Windows version from your website and run the setup.exe, I get an warning saying “SmartScreen prevented an unrecognized app from starting”. What do I do?
On Win8.1 click on More Info to reveal the “Run Anyway” button. Click the Run Anyway button and the install will proceed. There is probably an equivalent override option in Win7 and Win10.
10. Why can’t I see my Map window?
Sometimes the windows obscure each other. Try selecting the Map window from the Windows menu of Dashcam Viewer and it should be brought to the forefront. Also, see question #3.
11. Why do I see a black screen when I try to play a video (on Windows)?
This is rare but here are a few things to try:
- Make sure you’ve installed the K-Lite Codec Packs. This free 3rd party software installs codecs missing from Windows that are required for some dashcam models.
- Dashcam Viewer works best on Windows 10. Please try again on a Win10 machine. Older versions, like Win7, may work but have not been thoroughly tested.
- Turn off antivirus protection. There have been some reports of antivirus software interfering with programs like Dashcam Viewer.
- Make sure you’re not running Windows on a virtual machine. VMs may not have the necessary video hardware emulation.
12. My videos don’t play and I see this message. What’s going on?
This message will be displayed if there’s some kind of decoding issue with the video. The most likely cause is that you didn’t previously install the K-Lite Codec Pack (Windows only). This error can also if it’s taking too long to load a video for some reason. In that case try loading the video again (your OS may load it from cache the second time, which is faster). If that doesn’t work try moving the videos to a faster hard drive and load from there.
13. I have a Viofo A119. The movies play fine but I don’t see any GPS data in the Map or Graphs. What’s going on?
I have heard this complaint from a dozen A119 customers so far. I have examined sample movie files provided to me and have determined that there is no GPS data written into the movie file. Here are hex dumps of the movie file where the GPS data is supposed to be in sample movies produced by two different A119 dashcams. Only the A119 on the right is correctly writing data into the movie file.
This A119 is NOT working correctly. It is not embedding GPS data into the movie file.
This A119 is working correctly and saving GPS data to the movie file.
A number of A119 owners have corrected the problem by downgrading the firmware from 2.01 to 2.0. In one case the vendor (SpyTech) exchanged the customer’s A119 for a new one. Presumably this fixed the problem. If you send me a sample movie I can examine it to see if it has this problem.
UPDATE: Viofo notes that it addressed this issue in the firmware v2.02 update.
14. Does Dashcam Viewer work with the DDPai M6+ dashcam?
This popular dashcam is not “officially” supported. The way the DDPai M6+ manipulates files and stores GPS data on the card is unique among dashcam manufacturers. They store some of their GPS data in a folder called “103gps” although some folks had their GPS data in a folder called “203gps”. Furthermore, not all the GPS data is in these folders. Some of it is stored in an archive format and is dearchived by the dashcam when needed. So the state of files on the SD card is always in flux. Sadly, DDPai does not seem interested in supporting the desktop community and instead focuses on smartphone users. In a recent post in a dashcam forum DDPai states, “our products were designed to connect to smartphone for pictures and video sharing on social community, and we built our own community to make more fun to use our social car dvr, rather than just recorder.”
That said, Dashcam Viewer will look for DDPai “gpx” files in the 103gps and 203gps directories. So as long as there are filename-matching gpx files in the 103gps or 203gps folders then the DDPai M6+ is “unofficially supported” in Windows Dashcam Viewer. Unfortunately, the MP4 movie format they use is not compatible with the QuickTime Player 7 library so the movies don’t play in the Mac version of Dashcam Viewer.
15. My dashcam’s movies don’t play in the Mac version of Dashcam Viewer. Why?
The Mac version of Dashcam Viewer uses the same video backend as QuickTime Player 7 (not Quicktime Player 10). Although the reasons are not clear, a few dashcam manufacturers produce MP4 movies that are not compatible with QuickTime Player 7 (and therefore, not Mac Dashcam Viewer). These dashcams include DDPai M6+, Thinkware F750/F770, and Garmin DC20. Unfortunately, there’s not much I can do I my end to remedy the situation other than switching the video backend (something I’m contemplating). UPDATE: Dashcam Viewer 3 uses a new video backend and should now be compatible with the Thinkware F750/F770.
16. I would like to run Dashcam Viewer on my Mac and PC. Do I need to buy two licenses?
Yes, each platform is a separate purchase. Developing and maintaining two “separate but more-or-less equal” versions is actually quite challenging and time-consuming.
18. I’m using a Mac and when I try to run your software the first time I get a message like this:
Mac’s Gatekeeper is blocking DCV from running. In newer versions of macOS, it’s easy to override Gatekeeper: After copying Dashcam Viewer to your Applications folder, right-click on the Dashcam Viewer icon and select ‘Open’ in the popup menu. You will then be given the option to run the program even though it’s not from an ‘approved’ developer. Fortunately, you only have to do this once!
Another way is to temporarily adjust your Security & Privacy settings. Go to your System Preferences and select Security & Privacy. Then choose “Anywhere” for “Allow applications downloaded from:”. After you run DCV the first time successfully you can switch your Security&Privacy settings back.
19. Dashcam Viewer is hanging on my MacBook Pro with Retina display running Yosemite (OS X 10.10). Any idea why?
We have found that the Graphs display on Dashcam Viewer has an issue some Retina Macs. Try this tip from https://support.apple.com/en-us/HT202471.
Try opening the application using Low Resolution mode:
- Quit the application if it is currently open.
- In the Finder, choose Applications from the Go menu.
- In the Applications folder that opens, click the application’s icon so it is highlighted.
- Choose Get Info from the File menu.
- Place a checkmark next to “Open in Low Resolution” to enable Low Resolution mode.
- Close the window and double click the Application to reopen it.
20. When I use the “Export Clip” feature I don’t hear audio in the exported clip.
This is a rare issue but the customer who had this problem reported that it only occurred if the clip was played in Quicktime Player. The audio was heard correctly if the clip was played in VLC or the clip was uploaded to YouTube.
21. When I try importing a Dashcam Viewer GPX file into Garmin BaseCamp, I get an error that the file “is not a valid GPX file and cannot be opened.”
22. I just downloaded/purchased Dashcam Viewer for my new PowerUCC Panorama-G camera and noticed something odd. All the “extra windows” (map, graph, Data Display Window) are running about 30-seconds AHEAD of the actual video.
The problem is that the dashcam’s internal clock is not set to the correct time. This issue was confirmed by comparing the displayed clock time in the movie to the time captured by the GPS. Please make sure the camera’s internal clock is synced to GPS time.
23. Why doesn’t Dashcam Viewer work with the BMW Advanced Car Eye dash cam?
As a former MINI and 328i owner I would have liked to have made this dashcam work, but I’m afraid it’s got me beat—for now.
24. I have a Panorama X2 with front and rear cameras. How do I view both movies simultaneously in picture-in-picture mode on my Mac?
This mode is supported in DCV v1.6.3 and higher. See the FAQ section of the Users Manual for details.
25. I get the following error when trying to run the 32-bit version of Dashcam Viewer: “The program can’t start because MSVCP120.dll is missing from your computer. Try reinstalling the program to fix this problem.”
You need to install the “VS2013 Redistributable Packages” on your computer. Download and install the Redistributables from here:
26. I have a Windows PC and got the following error when I ran Dashcam Viewer: The ordinal 4369 could not be located in the dynamic link library LIBEAY32.dll.
This is an error due to multiple version of the LIBEAY32.dll on your system. User Dennis McKay was able to fix the problem on his PC. He sent a very detailed email on how he fixed the problem:
I found an old system at work that had a lot of miscellaneous software installed on it and 17 copies of LIBEAY32.dll. None of the copies were in the c:\windows\system32 folder but were in various software installation folders. I ran dashcamviewer and received the dll error. I took the LIBEAY32.dll from OpenSSL and placed it in the c:\windows\system32 folder and dashcamviewer ran without an error. On my computer I moved the LIBEAY32.dll from SysWOW64 to System32 and mine now runs without an error. Installing the 32 bit version of OpenSSL correctly places the dll in the correct system folder.
From what I have seen and some additional reading on Microsoft TechNet it appears that most programs install the version of LIBEAY32.dll that is used in developing the software in its own folder. So there are multiple copies and because it is not a registered dll, each program uses the version it installed. I tried putting this dll into the dashcamviewer directory and it still gave the error, so it expects to see it in the c:\windows\system32 folder. I have a fair amount of software installed on all of my computers at home and work and none of them have this dll in that folder.
I don’t know why only a couple of us have had this problem or what software the other users are installing that puts this file in the system32 folder. But I don’t think you need to change the way you are programming it and include this files since statistically the error rate is inconsequential and the fix is simple. I have never run into this problem before with this library file so just chalk it up to another one of those weird things thanks to Microsoft.
27. I don’t see any GPS data. Why?
Without more specific info it is difficult to diagnose the problem. Here are a few things to check:
1) Are you sure the GPS was ON and had established a lock on the satellites?
2) Are there any error messages displayed? Do you see any data traces in the Graphs window?
3) Make sure your 0803’s internal clock is set to the correct timezone and correct time. DCV relies on the correct timestamp of the movies to sync with the GPS data files. The GPS, your computer, and the dashcam should all have the correct time.
4) If that doesn’t work, send me a clone of your SD card that contains about 3 movies on it and I will try to diagnose the problem. It’s important that you send me an image of the SD card such that the file and folder structure is preserved. The structure should look something like that below. You can send me a zip of the SD card via https://wetransfer.com using my email address as the destination.
28. I am running Windows 7 and Dashcam Viewer shows a black screen when I try to play a movie.
Although many people have reported no issues with Windows 7 and Dashcam Viewer, a number of people have reported the ‘black screen’ issue. For that reason I no longer recommend Win7 for use with DV. I suggest a move to Windows 10, which has much fewer issues with DV. If you stick with Win7, you could try reducing the movie resolution to 720p on your dashcam’s settings, which may help, or installing the K-Lite codec pack.
29. How can I import a custom vehicle path (trajectory) if my movie doesn’t contain GPS data?
If your GPS data is from a separate source than your video camera (like a Garmin GPS receiver), you can export your GPS data to GPX file (see here for format), name the gpx file with the same base name as your movie but with a .gpx extension. If the gpx file is in the same directory as the movie file, Dashcam Viewer will load it.
30. Is there a version for the iPad?
Sorry, no iPad/iPhone version is in the works. With the large movie file sizes recorded by these cameras transferring data to the iPad would be very slow anyway.
31. I have an idea for a new feature.
Great! Send it to me: email@example.com
Due to my day-job and limited spare time I cannot guarantee your idea will be implemented promptly (or even at all). But don’t let that dissuade you. Many features currently implemented in DCV were supplied by users like yourself.
32. I think I found a bug.
Darn. OK, send it to me via email.
