Käyttäjä:Masa

masa on noob.

masa on myöskin sähkötekniikkaa "opiskeleva" noob.

masa ylläpitää omaa palvelintaan, jonka nimi on tällä hetkellä dual. dualilla pyörii irssi, webbiserveri, pellettipolttimen logitussoftat ja suurelle yleisölle on tarjolla 24/7 toimiva Hard-vaikeustason KillingFloor-palvelin. Suunnitelmissa on tarjota lisää pelipalvelimia, kunhan joskus saan paremman nettiyhteyden kotiin.

Gnome 3 default applications

nano /usr/share/applications/mimeinfo.cache nano ~/.local/share/applications/mimeapps.list

For default file manager, have this: inode/directory=nautilus.desktop;Thunar-folder-handler.desktop;

Some useful commands

Record a region from screen, with audio (can be used to record for example Minecraft). Shows the region outlines to align the window. ffmpeg -f x11grab -show_region 1 -r 25 -s 1280x720 -i :0.0+500,80 -c:v libx264 -preset fast -crf 22 -f alsa -i pulse -c:a libvorbis -b:a 96k -threads 0 -f matroska sda6/minecraft_withertaistelu_overview_2012-11-24_2.mkv

Another sometimes useful option fo x11grab:
-follow_mouse centered|<PIXELS>

When it is specified with "centered", the grabbing region follows the mouse pointer and keeps the pointer at the center of region; otherwise, the region follows only when the mouse pointer reaches within PIXELS (greater than zero) to the edge of region.

Random shell scripts

Safely shutdown a SATA hard drive (spins it down). Umount first! Usage example: scsiremove /dev/sdb

/usr/local/bin/scsiremove (needs sys-block/scsiadd and sys-fs/lsscsi):

1. !/bin/sh

if [ $# -ne 1 ]; then

       echo "Usage: $0 <device>"
       exit 1

fi

if ! which lsscsi >/dev/null 2>&1; then

       echo "Error: lsscsi not installed";
       exit 1

fi

if ! which scsiadd >/dev/null 2>&1; then

       echo "Error: scsiadd not installed"
       exit 1

fi

device=`lsscsi | grep $1`

if [ -z "$device" ]; then

       echo "Error: could not find device: $1"
       exit 1

fi

hcil=`echo $device | awk \ '{split(substr($0, 2, 7),a,":"); print a[1], a[2], a[3], a[4]}'`

scsiadd -r $hcil

---

Merge together video files in matroska containers (needs media-video/mkvtoolnix).

/usr/local/bin/merge.sh:

1. !/bin/bash

ALL="empty" DSTDIR=${1} FILES=${2}

for i in $(ls ${FILES}*) do

       if [ "$ALL" = "empty" ]; then
               ALL=${i}
               FIRST=${i}
       else
               ALL="${ALL} + ${i}"
       fi

done

1. COMBINED=$(basename $FIRST | sed "s/\.mkv/_all.mkv/")

COMBINED=`basename ${FIRST} | sed "s/\.\([a-zA-Z0-9]\{1,10\}\)$/_all\.\1/"`

if [ -f "${DSTDIR}${COMBINED}" ]; then

       echo "Error: the target file already exists!"
       exit

fi

1. echo "mkvmerge $ALL -o ${DSTDIR}${COMBINED}"

mkvmerge $ALL -o ${DSTDIR}${COMBINED} touch ${DSTDIR}${COMBINED} -r ${FIRST}

---

Encode videos into matroska container, with Ogg Vorbis audio and h.264 video (with x264 library). Needs media-video/ffmpeg, media-libs/libvorbis and media-libs/x264.

encode.sh

1. !/bin/bash

SRCDIR=/home/masa/Media/Fraps/Fraps/ DSTDIR=/home/masa/ware/dc/f/

SAVEIFS=$IFS IFS=$(echo -en "\n\b")

for i in $(ls ${SRCDIR}javaw*avi)

1. for i in $(ls ${SRCDIR}KillingFloor*avi)
2. for i in $(ls ${SRCDIR}*.avi)
3. for i in $(ls ${SRCDIR}Terraria*avi)

do

1. DST=$(echo ${i/avi/mkv})
2. DST=$(echo ${i/ /_})

i=$(basename $i | sed "s/^\.\///")

1. DST=$(echo $i | sed "s/avi/mkv/" | sed "s/ /_/g")
2. DST=$(echo $i | sed "s/mpeg/mkv/" | sed "s/ /_/g")

DST=$(echo $i | sed "s/\.[a-zA-Z0-9]\{1,10\}$/\.mkv/" | sed "s/ /_/g")

1. echo "$i -> $DST"

2. Tämä on se perinteinen:

ffmpeg -i ${SRCDIR}"${i}" -c:a libvorbis -b:a 96k\ -r 25 -c:v libx264 -preset slow -crf 25 -threads 0\ -f matroska ${DSTDIR}${DST}

chown masa:masa ${DSTDIR}${DST} chmod 644 ${DSTDIR}${DST} touch ${DSTDIR}${DST} -r ${SRCDIR}"${i}"
