omxplayer plays at speed 2.0 when using a pipe

[IpPsar01]

Some help is needed on the following:
I want to run omxplayer as a separate process and sent characters to it via a pipe in order to pause, stop, etc.
But when I run omxplayer and have it read from a fifo pipe it starts at playspeed 2.0!

The setup is as follows:
I create a pipe using: mkfifo /tmp/cmdVideo

On one terminal I start:
#!/bin/bash
export DISPLAY=:0
omxplayer -o local "/home/pi/Media/Videos/2019/2019-04-02 - Swan.mp4" </tmp/cmdVideo &

On another terminal I enter characters into the pipe.
To start the playing: echo –n . > /tmp/cmdVideo
To stop the playing: echo –n ‘q’ > /tmp/cmdVideo

The output from omxplayer is:
Video codec omx-h264 width 1920 height 1080 profile 100 fps 29.970030
Subtitle count: 0, state: off, index: 1, delay: 0
V:PortSettingsChanged: 1920x1080@29.97 interlace:0 deinterlace:0 anaglyph:0 par:1.00 display:0 layer:0 alpha:255 aspectMode:0
Playspeed 2.000
Stopped at: 00:00:10
have a nice day ;)

If run without the pipe it plays at normal speed:
omxplayer -o local "/home/pi/Media/Videos/2019/2019-04-02 - Swan.mp4"
Video codec omx-h264 width 1920 height 1080 profile 100 fps 29.970030
Subtitle count: 0, state: off, index: 1, delay: 0
V:PortSettingsChanged: 1920x1080@29.97 interlace:0 deinterlace:0 anaglyph:0 par:1.00 display:0 layer:0 alpha:255 aspectMode:0
have a nice day ;)

I have tested with different videos, doesn’t make any difference.

Any help is welcome.
Thanks in advance!

I am trying to do the same as you and although I have some issues, I do not have the same problem as you. For me it starts playback at normal speed, but I have issues after that.

Anyway, I think your issue is caused by that first DOT character you send to the FIFO. Try sending a SPACE character instead. If that does not work, send a second SPACE character separately (add a small wait in between sending them).

Thanks. I will play around with it at a later moment. Keep you posted.

This resolved it for me. Great.
It's now playing at the normal speed and due to that also with audio.
Thanks.
