1 second HDMI lag with omxplayer?

[hoothoot]

I have a script that plays video with omxplayer and xterm (for fullscreen).

Code: Select all

def play_vid_nonblocking(num):
        return subprocess.Popen(["xterm", "-fullscreen", "-e", "omxplayer", "-o", "hdmi", "-r", "/home/pi/Ligia/{:02d}.mp4".format(num)])

It seems that when the video function is called, there's a second or two where there is no HDMI output of any kind before the video plays.

This isn't an issue when running the script on my monitor, but when the Pi is hooked up to a projector, this 1 second interruption causes the projector's default "NO INPUT" screen to flash, which is annoying.

Any ideas here? I've already edited config.txt to include

Code: Select all

gpu_mem=192

Where should I go from here? Thank you in advance!

Try with "-r" removed. That option changes HDMI mode to match video framerate (for smoother video playback).
Most displays/projectors require between a second and several seconds to lock onto the new settings. That is unavoidable.

This did the trick, thank you
