man patch (package patch)

PATCH(1) General Commands Manual PATCH(1)

NAME
patch - apply a diff file to an original

SYNOPSIS
patch [options] [originalfile [patchfile]]

but usually just

patch -pnum <patchfile

DESCRIPTION
patch takes a patch file patchfile containing a difference listing produced by the diff program and applies those differences to one or more original files, producing patched versions. Normally the patched versions are put in place of the originals...

Example

.../views/tooltips$ patch tooltipmanager.cpp < tooltipmanager.diff
patching file tooltipmanager.cpp

'No news is good news' in this case.

A step forward - MouseOverAction.sh

The mouse over action can be a bit more flexible if the tooltips calls a script file and the script file calls the players:

Start play code:

Code:

    //Start Play
    //http://api.kde.org/4.x-api/kdelibs-apidocs/kio/html/classKFileItem.html
    //using m_item.mimetype() and m_item.localPath()
    QObject *parent;
    QString program = "/usr/local/bin/MouseOverAction.sh";
    QStringList arguments;
    arguments << m_item.mimetype() << m_item.localPath();
    QProcess *startPlay = new QProcess(parent);
    startPlay->start(program, arguments);

The MouseOverAction.sh is simple script file with cases. An example /usr/local/bin/MouseOverAction.sh:

Code:

#!/bin/sh

# MouseOverAction.sh Mimetype file

case "$1" in

      audio/x-ms-wma)
      ffplay -nodisp "$2"
      ;;

      audio/*)
      play "$2"
      ;;

      video/*)
      ffplay -x 640 -y 480 "$2"
      ;;
      
      *)
#     case trap
      exit

esac

The wma files are played with the ffplay (ffmpeg) other audio files are played with the play (SoX).

There can be more that one...

There can be more than one Dolphin installed:

The Dolphin+ plays previews - the standard Dolphin works as fallback

**Rog132** · Nov 28, 2013, 10:15 AM

Dolphin+

Building alternative versions of the KDE applications - Dolphin+

KDE CMake Tutorial: http://techbase.kde.org/Development/Tutorials/CMake

Needed from the kde-baseapps sources:

Directories:
- dolphin
- konqueror
- lib

Files:
- CmakeLists.txt
- *.cmake

Edit the CMakeLists.txt
- add CMAKE_PREFIX_PATH and CMAKE_INSTALL_PREFIX
- disable/comment out the unneeded directories (kdialog/keditbookmarks/...)

Add the MouseOverAction.sh code to the tooltipmanager.cpp: http://pastebin.com/trgvFBCw

Build

Code:

mkdir -p builddir
cd builddir && cmake .. -DCMAKE_INSTALL_PREFIX=/<Your_Path_Here>
make

Drag&Drop the Dolphin and the library binaries to the destination - at here to the /opt.

Add the Dolphin+ to the KDE Menu.

About the MouseOverAction.sh

The MouseOverAction is using the xdotool to read the mouse location and wmctrl to move, scale and raise the preview window.

Package xdotool

Package: xdotool
Priority: extra
Section: universe/x11
...
Description simulate X11 keyboard/mouse input
xdotool lets you programatically (or manually) simulate keyboard
input and mouse activity, move and resize windows, etc. It does this
using X11's XTEST extension and other Xlib functions.
...
Homepage: http://www.semicomplete.com/blog/projects/xdotool/

man xdotool

NAME
xdotool - command-line X11 automation tool

SYNOPSIS
xdotool cmd args...

Notation: Some documentation uses [window] to denote an optional window argument. This case means that the
argument, if not present, will default to "%1". See "WINDOW STACK" for what "%1" means.

DESCRIPTION
xdotool lets you programatically (or manually) simulate keyboard input and mouse activity, move and resize
windows, etc. It does this using X11's XTEST extension and other Xlib functions.

There is some support for Extended Window Manager Hints (aka EWMH or NetWM). See the "EXTENDED WINDOW MANAGER
HINTS" section for more information...

Package: wmctrl

Package: wmctrl
Priority: optional
Section: universe/x11
...
Description: control an EWMH/NetWM compatible X Window Manager
Wmctrl is a command line tool to interact with an
EWMH/NetWM compatible X Window Manager (examples include
Enlightenment, icewm, kwin, metacity, and sawfish).
.
Wmctrl provides command line access to almost all the features
defined in the EWMH specification. For example it can maximize
windows, make them sticky, set them to be always on top. It can
switch and resize desktops and perform many other useful
operations.

man wmctrl

NAME
wmctrl - interact with a EWMH/NetWM compatible X Window Manager.

SYNOPSIS
wmctrl [ options | actions ]...

DESCRIPTION
wmctrl is a command that can be used to interact with an X Window manager that is compatible with the
EWMH/NetWM specification. wmctrl can query the window manager for information, and it can request that cer‐
tain window management actions be taken.

wmctrl is controlled entirely by its command line arguments. The command line arguments are used to specify
the action to be performed (with options that modify behavior) and any arguments that might be needed to per‐
form the actions.

The following sections define the supported actions and options. Arguments to the actions and options are
written in the form <ARGNAME> in the descriptions below. The detailed syntax for writing arguments are in a
single section dedicated to that purpose...

MouseOverAction v0.2

Caps Lock as Preview Lock

The ffplay has controls while playing (man ffplay):

q, ESC
Quit.

f Toggle full screen.

p, SPC
Pause.

a Cycle audio channel in the current program.

v Cycle video channel.

t Cycle subtitle channel in the current program.

c Cycle program.

w Cycle video filters or show modes.

s Step to the next frame.

Pause if the stream is not already paused, step to the next video frame, and pause.

left/right
Seek backward/forward 10 seconds.

down/up
Seek backward/forward 1 minute.

page down/page up
Seek to the previous/next chapter. or if there are no chapters Seek backward/forward 10 minutes.

mouse click
Seek to percentage in file corresponding to fraction of width.

The 'Caps Lock' can be used to flip the preview from the auto mode to the controlled mode.

The 'Caps Lock' status can be read with the 'xset' command:

Code:

# Caps Lock will move the focus to the preview window
# and enable the ffplay controls
lockPreview ()
# Call: lockPreview windowtitle
{
   previewwindowTitle="$1"
   
   while [ 1 ] ; do
      if xset -q | grep "Caps Lock:   on" > /dev/null 2>&1; then
         wmctrl -R "$previewwindowTitle"
      fi
   done
}

Presentation Time Stamp

The ffplay can draw text on top of a video: http://ffmpeg.org/ffmpeg-filters.html#drawtext-1

A launchPlayer function with the pts on top of the video:

Code:

launchPlayer ()
{
# Call: launchPlayer windowtitle file

   localwindowTitle="$1"
   previewFile="$2"

   ffplay -vf drawtext='fontfile=/usr/share/fonts/truetype/freefont/FreeSans.ttf:fontsize=36:text=%{pts}:fontcolor=green: box=1: boxcolor=white' -window_title "$windowTitle" -x 1 -y 1 "$previewFile" > /dev/null 2>&1
   
}
