    Default Video on FPP

    Hi I'm playing a video playlist on my projector via FPP.
    What determines the output resolution-- where is this set? The video frame seems is cut off on the left and right.
    Reminds me of when the resolution is not set correctly in System Settings on my Mac when outputting to a projector.

    On a similar note, can I play both this video playlist and a non-related Pixel sequence at the same time? I tried both in scheduler and it did not work. I needed to select one at a time.

    Thanks

    how do you have FPP setup are you using a virtual matrix?Here is a page from manual explain virtualmatrix Screen Shot 2021-12-08 at 10.38.24 PM.png
    I use the 16x9 aspect 768x432 settings and it outputs good.
    Are you using XLights to sequence?

    So with this particular playlist, I did not go through any sequencer. I just took the raw video files and loaded them onto FPP as media only files.
    It works, but I cannot seem to get a correct resolution set.

    I typically use Vixen for sequencing.

    This is a bit complicated. The Pi sets the HDMI video signal based on the EDID it receives from the display device (projector or monitor) that's connected. To actually tell what's going on, you need to go to the command line on the Pi. Type
    tvservice -d edid
    and then
    edidparser edid
    This will read out all of the modes supported by the display, and near the bottom will tell you what the preferred rate is.

    If your image is getting cut off, it's probably more related to overscan than resolution.
    first see if your tv/projector has any settings to turn overscan off or on. If that doesn't work, you can try to change it on the pi.

    To change it, you'll need to edit the /boot/config.txt file
    find the line that says
    disable_overscan=
    and change it (if it's 1, change it to 0. If it's 0, change it to 1.
    save the config file and reboot the pi.

    This requires some knowledge of the linux terminal.
    You'll need to use a text editor like nano or vi. If you don't know how to do that, there's plenty of resources on google.

    I was just playing with video last night. You can play a sequence with the video as the media. However, if you want a sound file to play with your sequence, then the video will need to be triggered in your sequence via a Command Preset. The FPP 5.0 manual does a fair job of explaining how this works.

    I can copy/paste stuff into the terminal pretty well
    But... now do I get to the Pi terminal from the from where I currently am (Falcon Player OS image)?

    you can connect with an SSH client like putty. or there's a browser based SSH terminal at the bottom of the help menu.

    Hi Jon--
    when I try this using the terminal under the help menu it doesn't quite work for me. When I type the first command in I get the message "Written 256 bytes to edid " but when I enter the 2nd (edidparser edid) I get "-bash: edidparser: command not found"

    looks like edidparser isn't in the current FPP OS image. i did a quick googling and didn't find an answer. however i am seeing references to a parse-edid utility that may be a substitute. try this:
    Code:
    tvservice -d edid
    parse-edid edid
    It didn't work on mine. It stopped with a partial read. But your mileage may vary.

    I just found an online edid parser http://edid.tv. you can take the edid file created by the tvservice utility and upload it to this site and it'll parse and read out your edid information.
