Hi
@DVPlayer, I have a Viofo T130 and I was trying to use your software to view both front and interior channels simultaneously (I don't have the rear cam connected), but they didn't play at first and I think I found why so I thought I would give you some feedback.
I think it is a combination of how Viofo are naming the files and how your player is expecting them to be named.
The files are named like so:
YYYY_MMDD_HHMMSS_F - front channel
YYYY_MMDD_HHMMSS_I - interior channel
YYYY_MMDD_HHMMSS_R - rear channel
Here's an example:
2022_0928_183209_F - front channel
2022_0928_183210_I - interior channel
As you can see some of the files are not with the exact same timestamp in the seconds part and I think because of this your player (Dashcam Viewer as well) doesn't view them as part of the same trip and won't display them together.
I switched the video playback mode DVPlayer from 2 to 3 channels and after I open a file it showed at the top of each window how does it expect the files to be named and then after I changed the interior files ending from "I" to "S" it played both channels. There was an echo because it played both audio channels simultaneously as well (there is a few milliseconds delay between each, but I think this is down to Viofo)
Also I've noticed your player doesn't display the GPS info or is this a full version feature?
