Below describes the necessary steps for recording freely available media from the internet for your own personal use. You have to be on a system using pulseaudio, such as ubuntu, fedora, centos.
\end{enumerate}
-When recording from the screen, a large green-colored boundary box appears to allow you to easily frame the screen area to be recorded when you move it around to where you want to position it. In addition there are \textit{record cursor} and \textit{big cursor} check boxes which allow for also recording the cursor and for making the cursor bigger.

+\index{capture!digital broadcasting}
You can do real-time capture of a full transport stream of Broadcast TV. Record television programs using \CGG{} by setting up ahead of time to start recording later at the specified time. Then you can use \CGG{} to watch later and easily fast forward through the commercials or edit the program, deleting the commercials, to watch uninterrupted. Some details may be slightly different than what it is in the United States. There are 3 requirements you must have to take advantage of this capability.

The main menu pulldown, \texttt{Settings $\rightarrow$ Preferences $\rightarrow$ Playback A} and \texttt{B} Tabs, must be properly configured in order to take advantage of the Dual Screen Mode capability.
-In the main menu Window pulldown there are \textit{Tile left} and \textit{Tile right} options for the 2 monitors. If you have only 1 monitor, you will see no change upon activating these options. Tiling is possible due to the existence of one long horizontal screen display buffer. Tile left takes \CGG{} and moves all of its windows to the $2^{nd}$ monitor/TV and Tile right puts it back to the $1^{st}$ monitor. The left and right monitors are the left part or right part of a Playback A/B Xwindow host referenced in the Video Config Playback A/B for separate X screens. Shortcuts for Tile left and Tile rights are the letters \texttt{a} and \texttt{b} on the keyboard once you have set \textit{Remote Control mode}. Below is a summary of the configuration letters:

+\CGG{} DVB recording/playback can now easily be done in \textit{couch potato} mode using a remote control. This comes in handy when you want to playback on a big TV screen for multiple person viewing. You can use the Application/Menu key on the keyboard to toggle between standard \CGG{} usage or a Dispatcher methodology through use of a remote control, an Android programmed device such as a tablet, or keyboard. The Application/Menu key on most keyboards is between the Alt and Ctrl keys on the right hand side bottom and depicts a menu on it either with or without a pointer (see image below). THe Menu key is keycode 135. An ati-x10 Remote Control device (figure~\ref{fig:remote01}) is currently working with \CGG{} and other remote controls may work but have never been tried. The red box on the top left main screen of \CGG{} indicates Dispatcher Method access is activated which allows for keyboard grab which routes all key strokes until toggled off. Below are the currently defined operations.

When the remote is operated with the \textit{Power} (menu) button, there is a little orange box on the upper left corner of the display to indicate the remote state is active. If you do not see the little orange box when the menu key is tapped, the communication is broken and must be fixed before proceeding. Follow the directions in the paragraph below.

BIG NOTICE: the firewalls in your computer and wifi router can stop this thing dead. Re-configuring a firewall is tricky and varies from distro to distro. If possible, during setup it is suggested that you disable the firewall temporarily. For those with advanced skills, use tcpdump or wireshark to look for udp messages from the IP address of the device.

\section{The commercial DB}%
\label{sec:commercial_db}
+\index{capture! commercials database}
While watching broadcast television, it is possible to use \CGG{} to automatically mute commercials being aired during a broadcast capture. Visual muting as well as sound muting is done! You can NOT use ffmpeg for the format when working with the \textit{commercial DB}. This database that was added is a \textit{novel architecture} shared memory database, a \textit{Traveling Data Base} (TDB). With TDB you have direct access to the shared database presence (instead of having to go to the server).
Currently, to activate the commercial database (db) methods you must do the following as root:
-\begin{lstlisting}[language=bash,numbers=none]
+\begin{lstlisting}[style=sh]
cd <cin-path>/bin
mkdir /cinelerra #yes, currently only in the / filesystem
./cin_db /cinelerra/media.db #to create a new empty commercial capture database
Currently, only a customized \textit{ati-x10} (kernel mod required) radio remote control works. But this can quite readily be modified for other remote control models.

-If you want to transfer the data on a VHS tape or DVD disc into \CGG{}, you can do so by playing the media and recording while playing. This captures the media, which you are able to view as it plays, and writes it to a file so it can be played directly or edited. Because there is so much variation in hardware on both the Computer side and the Media Player side, these \textit{how to} directions are only a guideline. You will most likely still have to do some experimentation and testing to see what works for you.

The basic strategy consists of 3 operations: connect the relevant outputs to representative inputs, configure the capture card to match the video, and start the Record monitor. Each of these may have to be experimented with to get them correct for your hardware setup.
For example in a test case using the \textit{CX23418} capture card (an older/unusual single chip MPEG-2 encoder with integrated analog video/broadcast audio decoder), one end of an S-Video cable was plugged into the back of a DVD player and the other end plugged into this computer’s Capture card; the audio was plugged into the \textit{line in} on the computer sound card.

+\end{figure}
+
\begin{itemize}
\item Choose \texttt{Settings $\rightarrow$ Preferences $\rightarrow$ Recording} tab in the Preferences menu (figure~\ref{fig:recordingx}).
\item Choose a \textit{File Format} -- a common suggestion is \textit{ffmpeg} with a \textit{file type} of mp4. In some cases depending on your capture card, the File Format will be set to \textit{MPEG stream} capture. Some formats support MPEG stream capture technique, otherwise the data has to be decoded first and then encoded.
\item Check that the \textit{Audio In} section has the \textit{Record Driver} set to \textit{Alsa} with \textit{Device} set to \textit{default} as the Capture Source. If you are using something besides Alsa, change that selection accordingly. This may not always be default and you may have to change to something else based on your specific hardware. It has to match up what you see in our Control Panel on your computer. So for example, if your device is HDMI, than the \textit{default} could be \textit{HDMI}\dots instead.
- \item In the \textit{Video In} section, change the\textit{ Record Driver} to whatever makes sense for your capture card. The test case for the CX23418 would use Video4Linux2 MPEG. If unknown what your card uses, you should experiment with Video4Linux2 or Screencapture as good possibilities.
- \item Also, \textit{Device path} should be verified to be correct in case you have more than 1 device.

+ \item Also, \textit{Device path} should be verified to be correct in case you have more than 1 device. In the 2 previously mentioned devices, it should proabably be set to /dev/video0.

-\textit{Step 3}: Next use the \textit{File} pulldown to choose \textit{Record} and then the Recording menu will popup (figure~\ref{fig:vhs01}).
-
\begin{itemize}
\item Click on the Antenna icon ($3^{rd}$ icon from the left on the left side of the right hand screen window).
\item In the popup \textit{Channels} menu, click on \texttt{Add} which brings up the \textit{Edit Channel} menu.
\item Use the down arrow in the \textit{Input} box to display the available options. In the test case, and very likely your case too, \textit{S-Video 1} should be picked.
- \item In the Recording menu, be sure to designate a complete path and filename in the \textit{Path:} textbox which will be used to record/write the playing media. Remember you must have the media on a file in order for \CGG{} to load it on the timeline for editing purposes.

\item Then highlight \textit{S-Video} in the \textit{Channels} Menu. Again, the choice in the Channels Menu might not be S-Video -- choices could vary widely. Start recording in your Recording menu by clicking on the second icon from the left, next to the \textit{Transport} label (it is usually a round red colored button).
\item Next press \textit{play} on your media hardware device. If on the \textit{Video In} side window you see only noise, then S-Video or something else was an incorrect choice and you will have to perform some tests to find correct choices.

\end{figure}
Now you can \textit{Load} the file that you played and recorded via the \textit{Insertion strategy} choices on the bottom of the Recording menu and edit the file as usual. Note, that the audio and video may have started at slightly different times so you might have to initially line them up at the beginning using \texttt{nudge}. Generally once they are correctly aligned they will stay that way. Nudge is in the expanded patchbay. The nudge value is the amount the track is shifted left or right during playback. The track is not displayed shifted on the timeline, but it is shifted when it is played back.
