Hi John,

I currently have a problem with DCV since upgrading from Mac 3.7.0 to 3.8.0, whc I did on 31st December 2021:
The initial problem is that the video wasn't shown nor was the map.

I updated via the program itself and saved the .dmg file before I ran it.

I initially thought that it might be that I'd downloaded the M1 file instead of the Intel one, so I visited the DCV website and downloaded the Intel version as I have an older Mac (2015 MacBook Pro, Quad-Core Intel Core i7, 2.5 GHz, osMac Big Sur 11.6).

I installed the 3.8.0 Intel version and had the same results.

I downgraded and installed 3.7.0 (from my folder of older DCV .dmg files) over 3.8.0 (without first deleting 3.8.0) and this improved things but this is the current status:

Files on External hard drive: DCV shows everything OK, i.e. video, audio, GPS location on (Google) map
Files on SD Card: DCV does NOT display video. Audio and GPS location on (Google) map is OK, speed shown in the (blank) video window. QuickTime Player plays files OK with audio and video.

Is this a resource (i.e. SD Card) access problem that I've caused?

So, a couple of questions:
1. What have I done wrong? As DCV updates normally go without a hitch.
2. What can I do to get 3.7.0 and preferably 3.8.0 working fully with both external hard drives and SD Cards?

I have thought of fully deleting DCV and installing 3.8.0 as a fresh new install, but I can't work out how to delete it on my Mac! :shame:
Could somebody advise me? Also, will deleting it affect my registration code and do I need to have that handy for a re-install?

Many thanks,

@Privateer I apologize for the issues you're experiencing. I recommend trying the "hard reset" procedure in whichever version of DCV you are using:
  • 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 the "Yes" button
This clears out Dashcam Viewer's settings and resets to defaults. If you're using a registered version of Dashcam Viewer, yes, you will need to re-enter your registration code again (I can provide this to you if you can't find it). Then try loading your videos again and see if everything is back to normal.

Not to bore with details but for those that are interested, here's little background info about Mac Dashcam Viewer v3.8.0.

The actual source code differences between 3.7.0 and 3.8.0 are very very minor. But v3.8.0 is different than earlier versions in a few significant ways. First of all, I moved the entire project from a 2015 MacBook Pro (Intel) to a 2020 MacBook Air (M1). That is not only a major change in CPU architecture, but also a change in macOS version (Big Sur vs Mojave), a change in Xcode compiler version, a change in build process (Intel+arm64 vs just Intel), a change in auxiliary library builds, and a change in application signing, bundling, and entitlement process. Although both Intel and M1 versions of 3.8.0 work for me, I suspect one of these differences is the culprit that's causing you grief (probably the last item I mentioned). I will be investigating this further and come to the bottom of it.

John

I have encountered similar issues with a speedcam database program I supply. Which Robert knows :)

When I bought a new PC recently and loaded Visual Studio 2022 it tried to recompile using the latest .net architecture and I had to manually switch it back to use .net 4 so all current installations would work.

Hi John,

Many thanks for your quick reply.

Then try loading your videos again and see if everything is back to normal.

I was lucky, I found my registration code from December 2016! (y)

I did the above and then installed 3.8.0 (Intel). I loaded up a new SD card with today's dashcam footage and everything was OK, the video showed, speed in the video window, and location on Google Map. This was before I made any changes in Preferences.

One thing that was 'slightly wrong' was the video was stretched horizontally. So I went to Preferences | General and changed:

Temperature units from F to C
Aspect Ratio from Fill to Maintain

With Aspect Ratio as "Maintain" setting, I get a blank video
With Aspect Ratio as "Fill" setting, I get the video working
I have switched numerous times and the above stays true.

I also lost the Google Map on the first occasion that I changed the Preferences | General settings but after restarting DCV I'm afraid that I cannot recreate the problem as the Google Maps have stayed operational for all other times.

Summing up
It appears to be the use of the Aspect Ratio setting in "Maintain" that causes the problem. This is easy to live with as I have found that the Aspect Ratio "Fill" setting is OK to use. As 3.8.0 would have taken the Preferences from 3.7.0, this makes sense as I would have had the Aspect Ratio in the "Maintain" setting. Your advice to Hard Reset DCV brought the Aspect Ratio problem to the surface.

Once again, many thanks for your help and advice.

Kind Regards,
Robert.
