[Announce] Mplayer touch screen control

Yet another mplayer interface !

As far as I know the media player is closed source and you have no chance to change the user interface.

But mplayer is flexible. Therefore I have written a python script and some shell scripts which control mplayer in slave mode via touch-screen. The keyboard is not necessary.

You can switch between the two menus by touching the lower left corner of the touch screen.

Here is an image how to control mplayer in virtual menu 1:

Here is an image how to control mplayer in virtual menu 2:

To quit mplayer press menu 2 (lower left corner) and then press quit (upper left corner).

Since I created the package by hand without scratchbox I am not sure if all dependencies are met. Let me know if something is missing.

Here is the package:
http://torsten-traenkner.de/wissen/n..._1.0_armel.deb

Local installation:

Code:

wget http://torsten-traenkner.de/wissen/n900/mplayer-touchcontrol_1.0_armel.deb

sudo gainroot

dpkg -i mplayer-touchcontrol_1.0_armel.deb

To use the scripts open a terminal and use "mm". For example:

Code:

mm /home/user/MyDocs/.videos/Nokia_N900.mp4

Currently mplayer is slow. Therefore the scripts might not be that useful. Maybe it is better to integrate the touch-screen interface in vlc.

The code can also be used for other applications.

Code:

The main script is:

/opt/maemo/usr/bin/mplayer-touchcontrol/touchscreenEvents.py



it reads the touch screen events from the touch screen device



/dev/input/ts

Re: [Announce] Mplayer touch screen control

This looks neat. Any chance you can post the sources? I'd prefer to look at them before installing.

Re: [Announce] Mplayer touch screen control

They are probably in the package (python + shell?).

Read the sources without installation:

Code:

mkdir test

cd test

wget http://torsten-traenkner.de/wissen/n900/mplayer-touchcontrol_1.0_armel.deb

ar xv mplayer-touchcontrol_1.0_armel.deb

tar xzvf data.tar.gz

cd opt/maemo/usr/bin/mplayer-touchcontrol/

cat touchscreenEvents.py

Basically, I read the events from /dev/input/ts. These are 16 byte for each touch on the screen.

Meanwhile, I have found MediaBox. Maybe the touchscreen interface would fit best into MediaBox since it has a better performance than mplayer.

Here is the code of the main script:

Code:

#!/usr/bin/python

# -*- coding: utf-8 -*-



# needed for pack and unpack

import struct

# needed to execute process

import subprocess

# needed to flush

import sys



# positions/buttons on the touch screen:

#

#  1 | 2 | 3

# ---+---+---

#  4 | 5 | 6

# ---+---+---

#  7 | 8 | 9



x = 0

y = 0

z = 0

touchScreenDeviceName = "/dev/input/ts"



# int, int, short, short, int

format = 'iihhi'



def touchScreenpressed(x, y):

  # print "pressed: ",x," ",y

  if x > 530:

    position = 3

  elif x > 300:

    position = 2

  else:

    position = 1



  if y > 315:

    position = position + 6

  elif y > 170:

    position = position + 3



  print "position: ",position

  sys.stdout.flush()

  subprocess.call(\

   ["su user -c /opt/maemo/usr/bin/mplayer-touchcontrol/"+str(position)+".sh &",

   ""], shell=True)



# open file in binary mode

touchScreenDevice = open(touchScreenDeviceName,"rb")

event = touchScreenDevice.read(16)



while event:

  # read single values from the 16 bytes

  (time1, time2, type, code, value) = \

    struct.unpack(format, event)



  # absolute coordinates

  if type == 3:

    if code == 0:

      x = value

    if code == 1:

      y = value

    if code == 2:

      z = value



  # synchronisation of coordinates ready

  # if type == 0 and code == 0:

  #  print x, ":", y



  # touchscreen

  if type == 1 and code == 0x014a:

    # pressed

    if value == 1:

      x = x / 5

      y = 500 - (y / 8)



      #print "pressed : ", x, ":", y

      touchScreenpressed(x, y)



  # read next event

  event = touchScreenDevice.read(16)

Thanks for sharing. This could really be useful as a full screen control interface for MediaBox.
