BlackVue video to image processing not working on Windows 10

[robertaustinbell]

When I run the command to extract the images from the BlackVue video it processes the first video clip but fails after that.

Here is what I am getting in powershell.

Seems you have a similar failure to @mikelo with a Gopro

I dont have an answer. I am running the Blackvue on Linux without fault.

[mikelortega]

Indeed, as @bob3bob3 says, I have exactly the same problem with a GoPro Session 4. Here is a link to the forum post. I also think it has something to do with ffprobe.

[mikelortega]

I'm just trying to guess, but I think this commit can be related:
revert: duration extraction - master v0.5.0 - commit ead2c0ed0ff5b85c7074f8862e9db5288370161f

Hi @robertaustinbell, I will look into this issue.
However, if you have a Blackvue, I recommend you just upload the videos with the new tools send_videos_for_processing command, these are then processed on the cloud, which is more practical than sampling it on your device.
You can read more about it here:
https://github.com/mapillary/mapillary_tools#blackvue

[robertaustinbell]

So when I run that command I get the same error. Also worth noting that I am on the most recent version of the package.

[josealb]

We are looking into the issue @robertaustinbell do you only get this error when using the send_videos_for_processing command? Can you use mapillary_tools successfully with other cameras otherwise?

@velmyshanovnyi can you try using the send_videos_for_processing command as suggested to @robertaustinbell above? This is the recommended method for Blackvue uploads from now on

[mikelortega]

I'd like to mention that I upgraded to the last version (Apr 16, 2019) and now it works correctly. I posted in the forum the workflow I'm using to upload videos. Thank you.

[velmyshanovnyi]

thnx

your fix is working! :)

im use video_process_and_upload

%MapiCamMapillaryTools% video_process_and_upload --advanced --version --verbose --import_path "%BlackVueFolder%\Record%BlackVueFPS%fps" --video_import_path "%BlackVueFolder%\Record" --user_name %MapiCamUsernameAtMapillary% --geotag_source "blackvue_videos" --geotag_source_path "%BlackVueFolder%\Record" --offset_angle %BlackVueOffsetAngle% --use_gps_start_time --interpolate_directions --duplicate_distance %BlackDuplicateDistance% --video_sample_interval %BlackVueInterval% --device_make "Blackvue" --device_model "DR900S-1CH" --overwrite_EXIF_gps_tag >> %MapiCamLOG%

[josealb]

@robertaustinbell we could reproduce the Unauthorized error on our machines. You can fix it by re-authenticating with mapillary_tools authenticate --advanced
Could you try that and let me know?

[DavidMetcalfe]

@josealb Just want to point out that send_videos_for_processing is not viable for videos where only a portion of the contents is viable for upload (such as completing a portion of a street and then turning into a driveway). Being able to process locally, and selectively upload the portion that will be of use to the community without the rest of the content is important, and if I upload, the content is automatically published and requires me to delete one image at a time.

[ptpt]

Please try the latest version: mapillary_tools upload_blackvue path/to/blackvue_videos which is equivalent to send_videos_for_processing
