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.
Support for writing data in segmented files (to avoid 2GB file
Support for recording audio in MP3 or PCM, with configurable
frequency, mono/stereo, etc.

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
Simultaneous preview and capture
Support for multi-processor machines
