Hi,

I can drop the file into the programme pupil player but then i just see a grey screen. The whole video is grey. I don't know what the problem is. Can you help me?

papr commented 2 years ago

@clussi Could you please share a screenshot and the player.log file? You can find it in the pupil_player_settings folder.

Based on the folder name, this looks like Pupil Invisible recording. There are two explanations for the gray video:

  1. The scene camera was not connected during the recording
  2. The scene video recording did not complete successfully and the video file may be corrupted

Could you share the recording with info@pupil-labs.com for concrete feedback?

Also have this problem. I'm planning to use a screen-record video as the world video, but after adjusting the video into 30fps 1280*720, the warning still shows up. I also don't know what the problem is. Could you please gave me a hand? GitHub-pupil-problem1 图片 Plus, when I drag the screen-record into video overlay, the warning also shows up. 图片

@zora-wxy How did you generate the world_lookup.npy file? And do you have a world_timestamps.npy file, too?

zora-wxy commented 2 years ago

The world_lookup.npy file is automatically generated. The world_timestamps.npy file isn't in the folder. I wrote a fake world_timestamps.npy file after reading this message, but it still can't run successfully because the pupil data can't be read. 图片

May I know how to deal with these .npy files so that I can make the screen-records combined with these pupil data when the world.mp4 file is missing? Or is there any document I can read?

Please try the following approach:

  1. Delete all world*files
  2. Use this script to convert the externally recorded video to generate the correct timestamps.
  3. Install this overlay plugin, open the original Pupil Capture recording, enable the plugin, and drag and drop the world video ontop. Then adjust the temporal offset in the plugin's menu to align the world video with the original recording.
