I am having a problem with geotagging a video with a GPX file

Basic information

Steps to reproduce behavior

I have recorded a video with my Insta360 X3 and I have a .gpx file. Now I am trying to upload it with the command line using this command: mapillary_tools video_process "C:\Users.....\Downloads\Mapillary Tools\VID_20230107_150950_00_235.mp4" --geotag_source "gpx" --geotag_source_path "C:\Users......\Downloads\Mapillary Tools\VID_20230107_150950_00_235.gpx"

Actual behavior

Afterwards I get this error: ERROR - MapillaryFileNotFoundError: Import file or directory not found: C:\Users.....\Downloads\Mapillary Tools\mapillary_sampled_video_frames

Does someone know how to fix this?

I just added the missing folder.

@xdTAGCLAN

See #599 I was getting the same error and it was because no frames were being generated due to early exit.

2023-02-18 10:44:54,531 - WARNING - Since sample geotags have been written in EXIFs when you sampled videos by distance (3.0 meter(s)), so we force the option "geotag_source" to be "exif" to avoid unnecessary geotagging from the videos again

This indicates it tried to use distance based sampling, which will of course fail if your video is empty and you are trying to add gps data.

My solution was to switch to time based sampling.

@Zaneo made the point there. Switching to interval-based sampling can fix the issue:

# add --video_sample_distance=-1 --video_sample_interval=2 to enable interval-based sampling
mapillary_tools video_process YOUR_VIDEO_PATH --video_sample_distance=-1 --video_sample_interval=2 --geotag_source "gpx" --geotag_source_path GPX_PATH

Meanwhile I am fixing it either by adding proper message or default to interval-based sampling when geotag_source is specified.

Thank you!

Fixed by simply adding the error message "Geotagging from "gpx" works with the legacy interval-based sampling only. To switch back, rerun the command with "--video_sample_distance -1 --video_sample_interval 2". Let me know if it makes sense.

Ideally we should handle this GPX geotagging in sample_video with distance-based sampling but it requires some effort. Maybe next step.
