For example, Sony action cameras do not embed GPS information in the video itself, but rather in a separate file. You can now convert that seperate file to GPX and upload it together with the video to Mapillary (see instructions).
Happy uploading and cheers to @nikola on the implementation.
Let’s say I have a mp4 video and a gpx file, but the gpx file is way longer than the video, and at least that the gpx is still recording while I am recording a video, is it possible to upload the video to Mapillary? I have tried it a month ago however it is stuck at ingesting until now, probably because the gpx is not trimmed?
@Zh9567 - in this case you need to trim the gpx file to match the start and end points of the video recording. You can use something like https://gpx.studio/ (or many other tools) to do the trimming.
