Video not playing correctly

What are you trying to achieve?: playing videos

Hello,
I am running a new experiment where I present 1s dynamic faces (a total of 72 mp4 videos) which have emotional sounds on them, but I am encountering issues when running them.
Two main things are happening:

  1. When I use the moviepy backend version I get a warning message saying "Parameter volume has unrecognized inputType “float”. What is happening in this case is that the video is running so fast that only a few ms of it appear, while the volume overlaps with the response time.
  2. I then used the ffpyplayer backend version and with this parameter the video plays for 1s and it stays on the screen for longer than 1s while the sound is looping.
    Here is the message I get on psychopy:
    WARNING: pytables package not found. ioHub functionality will be disabled.
    1.5280 WARNING Monitor specification not found. Creating a temporary one…
    ioHub Server Process Completed With Code: 0

When I use my Mac i have no issues playing the videos for 1s using the moviepy backend.

Any input would be appreciated.

Hi,

I’m having the exact same problem as well! Did you find a solution?

I also have the same problem with audio looping when using ffpyplayer, and crashes and other error when using others
