Time slider broken with missing video file

[J.D. Laurence-Chasen]

Hey Ben, Here’s a new (low priority) one:

1. Have trial with 2 AVI videos, tracking complete
2. Video files are deleted from source folder for space saving
3. Need to check the video to confirm behavior, so re-download camera 2 avi and put in source folder
4. Open XMALab file – time slider is broken, plot window shows 2D points, but slider doesn’t show any frames

When I download the camera 1 video and re-open the trial, it works fine.

‌

Thanks!

JD

Hi JD, xmalab does not store how long the video sequence was but does only reads the length once a video file is opened. I can check if i can change this for the next version

Awesome! Thank you

But I don’t think that’s the exact source of the bug, because I just tested again, and with cam1 video missing, and # of frames went from 1124 to 100, but with cam2 video missing, number of frames is correct. So I think XMALab is probably looking at just cam1 for sequence length, which would be an easier fix than storing the length.

Hi JD,

Thanks for the info. I will check the code but believe it should check both cams.

fixes #228 : Added nbImages of Trials in xma-files. This sets the sequence length correctly when no video data is provided for new xma-files.
