Videos with pvr350 can be grabbed with "cat /dev/video0 > output.mpg" and can be played with "cat output.mpg > /dev/video16".
In order to transcode from 23.97 avi to 25 mpg (dvd) a video file use: mencoder mymovie.avi -of mpeg -mpegopts format=mpeg2:telecine -oac lavc -ovc lavc -lavcopts acodec=mp3:vcodec=mpeg2video -ofps 25 -o mymovie.mpg
If you want to play it directly to the tvout modify it this way: mencoder mymovie.avi -of mpeg -mpegopts format=mpeg2:telecine -oac copy -ovc lavc -lavcopts vcodec=mpeg2video -ofps 25 -o /dev/video16
Small program that sends audio output to the pvr350: pvr350player
After emerging nvidia-drivers run: eselect opengl set nvidia Additionally merge "media-video/nvidia-settings".
gifsicle command line: gifsicle -D 2 -l -d 15 -t '#FFFFFF' arrow1.gif arrow2.gif arrow3.gif > arrowanim.gif -t '#FFFFFF' tells the program to handle the color white as transparent. -D 2 tells to use the background when the transparent part of the image is drawn. -l tells to loop, and as there is no number specified, it loops forever. -d 15 tells to wait 15 hundreds of seconds between the different frames.
Programs used to setup the modeline in linux:
xvidtune: try out different settings.
read-edid: tries to read the EDID informations in the monitor itself.
amlc
Use xvidcap as Desktop-recorder / screen capture utility.
Use 3ddesk as a fake 3d desktop switch utility.
Use avimerge to merge multiple avi files into a single one (contained in the transcode package).
Motiontrack to find differencies (e.g. if something has moved) between two pictures.
How to convert "ts" (transport stream) files to othe formats: http://www.togaware.com/linux/survivor/Converting_Transport.html http://gentoo-wiki.com/HOWTO_Master_a_DVD_from_DVB_transport_stream http://www.m740.de/wiki/Aufnahmen_schneiden_und_auf_DVD_brennen_unter_Linux
A nice site where to find subtitles for movies: http://www.moviesubtitles.org/
Use ogmrip to convert DVDs to mkv-files.
"feh" is a lightweight image viewer.
Use dvbcut to cut and remux "ts" files to "mpg".
To be able to recode to x264 or just backup some protected DVDs, use 1) dvdfab decrypter or CopyToDVD (from vso-software), then FixVTS, then Nero Recode or ogmrip or whatever.
In order for a user (userA) to have access to the X display started by another user (userX), the user requesting access (userA) will have to set the variable XAUTHORITY to the path of the .Xauthority file of the user owning X (userX). In this case: userA@computer ~ $ export XAUTHORITY=/userX/.Xauthority The .Xauthority file is re-created each time X is started! Therefore put some kind of e.g. chmod 704 /userX/.Xauthority in your X-start file (e.g. /etc/X11/Sessions/enlightenment)
Use podcatcher to download podcasts. Files which are being downloaded are stored in the /tmp/ directory.

When using Gnome, add to "System > Preferences > Startup Applications" an entry for "/usr/bin/compiz-manager". Other ways of setting it up with Gnome didn't work for me.
"cvt" can be used to generate the modelines of xorg.conf.

Additional truetype fonts can be put under "/usr/share/fonts". Afterwards X needs to be restarted.
To generate animated gifs:
Create somehow the single frames in any format, e.g. png.
Perhaps change a color to transparent (using Imagemagick): for f in frame* do echo Processing $f and creating transparent-$f convert -transparent "rgb(255,255,255)" -fuzz "25%" -format gif $f transparent-$f.gif done
After having created the animated GIF, you can change the properties of some of the frames. E.g. here... gifsicle -b mylogo.gif -d900 "#0" ...I set the delay of the first frame of the animation to 9 seconds.
FFMPEG commands:
Create a screencast of the desktop 0.0: ffmpeg -f x11grab -r 25 -s wxga -i :0.0 /tmp/outputFile.mpg
Create a video out of single images ffmpeg -f image2 -i img%d.jpg /tmp/a.mpg
Webcam reminders:
Use the programs "motion" or "zoneminder" to use the webcam to monitor the house/flat/area.
Install the package "v4l-utils" for the extra v4l2 utilities.
Run the command "v4l2-ctl -d /dev/video --list-formats" to show the formats supported by the webcam.
Run the command "v4l2-ctl -d /dev/video --list-formats-ext" to show the formats and resolutions supported by the webcam.
Run the command "v4l2-ctl -d /dev/video --set-fmt-video=width=,height=,pixelformat=" to set the resolution and streaming format of the webcam. So, e.g. "v4l2-ctl -d /dev/video1 --set-fmt-video=width=1280,height=720,pixelformat=MJPG" to set the resolution to 720p and a JPEG stream.
Test the camera with e.g. "mplayer -v tv:// -tv device=/dev/video1:driver=v4l2:width=1920:height=1080:fps=30:outfmt=mjpg"
List the available framebuffer resolutions: hwinfo --framebuffer
To set a different font in Eterm: Set it e.g. like this: Eterm -F -misc-fixed-medium-r-normal--14-*-*-*-*-*-iso8859-1 Find out how the cryptic string has to/can be set with the utility "xfontsel". Perhaps get rid of the menu at the top with the parameter "--buttonbar 0".
