HDMI Drops

Mon Jul 29, 2013 10:30 pm

I just finished a video looper project that plays video files the Pi finds on usb storage using omxplayer. Here's the thread where I asked a few questions about the code...http://www.raspberrypi.org/phpBB3/viewt ... 0&p=383559

The project works wonderfully except for one thing... every time omxplayer starts a new clip, the HDMI signal drops out for half a second. This causes the tv to refresh the input, so I lose sound for a few seconds, and the ugly source identification appears on the screen (see attachment). I've tried this on two separate tvs, and the same problem occurs on HDMI only. There are no problems on the composite output.

I just export H.264 files directly from adobe premiere, and the pi plays them beautifully! Omxplayer plays 1080p @ 30Hz without any hiccups during playback. My omxplayer code is below... any suggestions to eliminate this interruption?

Code: Select all

#!/bin/bash

while true; do

  cd "/media/PIDRIVE"
  set -- *.mp?
  for i;do
  omxplayer -r -o hdmi "$i"
  done

done

Michael did you found a solution meanwhile?

I have the same problem and it would be nice if you could give me a hint!

cheers

No :| Let's see if gkreid's solution works

I'll try that... just curious as to what that argument means. I've found very little relating to omxplayer's arguments.
