Exporting Data to AVI Video and PNG image

Metavision Player allows to export events data to AVI video and PNG image.

To export data, follow these steps:

  • open a command prompt and move to a directory where you have write permission

  • start Metavision Player (either with a live Prophesee’s camera or with a RAW file):

Linux

cd /home/username
metavision_player

Windows

cd C:\Users\%USERNAME%"
metavision_player.exe

  • events data will be shown in the viewer window on the screen

  • press “a” key on a keyboard to switch to Analysis Mode

  • GUI controls will be shown on the screen

  • adjust export settings if needed (FPS, accumulation time, etc.); for more detail, see GUI controls in Analysis Mode

  • press “v” key to export to AVI video with selected settings

  • press “s” key to export the current frame to PNG image

The exported video will be saved to an AVI file (video.avi by default) in the current directory. The output filename can be changed with the command line option --output-avi-file.

The exported image will be saved to a PNG file (frame.png by default) in the current directory. The output filename can be changed with the command line option --output-png-file.

You can modify the GUI settings and export data as many times as needed using the same acquired events.
