SUGGESTED FEATURE - Map tile

[MarcFinns]

Hello, this is an idea to make use of the empty tiles in the output videos.

• In one, the info from the event.json could be displayed (i.e. coordinates, city, timestamp)
• In the other, a map with a red dot on the coordinates from event.json.
  Anyone interested?

Great idea!

I also think it sounds like a good idea. For what it's worth, I added an option to prepend a map of the event location at the start of the video here, #154, which is now available after some fixups of my mistakes by @ehendrix23.

I don't know enough about ffmpeg to figure out how to add it in one of the empty tiles though, unfortunately.

This is actually a very good step, thanks. If you can generate already the one-frame video, looking at the code it should not be impossible to add it to one of the unused frames.

Hi there, is this mod working on linux?
I get tesla_dashcam: error: unrecognized arguments: --title-screen-map

[SimonKagstrom]

@MarcFinns , it should be --title_screen_map. I think it maybe changed since the first version of the pull request.

I got an even bigger error, The entire video is the map.

Can you open another issue for this and then run it with DEBUG log level and provide that together with full command (including parameters)?

I ran a little test and figured out how to add a map tile in the top left corner with a manual ffmpeg command based on what the script generates. The magic line was this:

[right1][map] overlay=eof_action=repeat:repeatlast=1:x=0:y=0 [map1];

The important bit is to turn on "repeat" and set "repeatlast=1" or it'll just flash the image briefly and go black.

You also need to add a new input with the map image (most of the code is already there from the title screen option).

I'm not familiar enough with the script to turn this into a full PR, esp. when you want to support multiple layouts and such, but it might be a good starting point.

My full command looks something like this:
