       dvr - Digital Video Recorder




       This  manual page documents briefly the dvr-qtgui command.  This manual
       page was written for the  Debian/GNU  Linux  distribution  because  the
       original program does not have a manual page.

       dvr  is  is  a  tool  to  record  movies  on a computer equipped with a
       Video4Linux-compatible video capture card. It can record  and  compress
       data at up to 25 fps in real time, using recent codecs like DivX, Indeo
       5, MPEG4, and others.

       Features include:

              Support for writing data in segmented files (to avoid  2GB  file
              size limitations)

              Support  for  recording  audio  in MP3 or PCM, with configurable
              frequency, mono/stereo, etc.

              On-the-fly capture and compression (requires a fast processor)

              Horizontal margin removal during capture (saves disk  space  and
              processor  ressources  when  recording  movies  that  have black
              top/bottom margins, such as 16/9)

              Detailed monitoring during recording (free  space  left,  frames
              lost, CPU usage, etc.)

              Configurable record start time and duration

              Large  number  of  configurable  parameters  (size, image depth,
              codec attributes, TV parameters, etc.)

              Session management (saving parameters on exit and reloading them
              on launch)

              Simultaneous preview and capture

              Fullscreen preview

              Support for multi-processor machines

              Session management

              Graphical user interface


       There are no command line options.

       The GUI is splited in several parts :

              General : configuration of the format of the input video (width,
              height, bits per pixel, ...), length in time, and others.

              Video codec : configuration of the video codec used

              Audio codec : configuration of the audio codec used

              Video : configuration of the video interface used :  norm  (PAL,
              SECAM, ...), input, channels, ...

              Monitoring : show statistics about the current recording

       The button at the bottom-left of the window is used to start recording,
       while the button at the bottom right is used to stop it. These  buttons
       are always visible.

       In  order  to  configure the channel list ("Video" section) you need to
       select a channel with your favorite TV program,  then  launch  DVR  and
       save  the tuned channel. Repeat the operation for each channel you want
       to configure.


       You need to launch your favorite TV program once and close  it,  before
       the first execution of DVR since the last reboot of your computer.
