Using an FME blog posting I extended a workflow developed by Dmitri Bagh in which he captured video and GPS data in both Car and Equestrian modes of transport. The workflow synced the video and GPS track file data to generate a co-located web application showing location map marker location and the video captured. The form factor in this workflow uses drone captured video which is watermarked using a ‘Subtitles’ file. The subtitles contains the UAV telemetry and location details at a coarse timing interval. The workflow being presented will detail how FME was used to parse the watermarked video to create a flight track vector from the subtitles to display the flightpath on a lightweight javascript web application showing synced map and video player frames in a web page similar to the workflow from blog post.

6. Collect Imagery & Lidar
UAV teams fly
missions collect data
FME stack
SysCaller + ffmpeg to
get stats of video,
then assemble js and
html, upload to S3
The result
Link to webapp
third
Some tips
Down sample the video.
Timestamps are fun
?
3rd Party Libraries are EASY
Using SysCaller and cmd line parameters.
.mp4
.gpx
.srt

7. Read subtitles file (.srt)
Frame
Timestamp
Location

8. Read input Video & table write html

9. Extensions

10. VideoRotator

11. VideoConcat

12. Create YouTube link

13. All the Videos
Once you begin playing with the third party libraries within FME the
sky is the limit.

14. Coordinate space
Be flexible on input files / types
Timestamps
machine OS nuances
FME Video (pitfalls)

15. Extract frames
join XY, create EXIF
pass to ML workflows
FME Video (wins)
