streamer(1) General Commands Manual streamer(1)NAME
streamer - record audio and/or video
SYNOPSIS
streamer [ options ]
DESCRIPTION
streamer reads audio and/or video data from /dev/video0 and /dev/dsp and writes the data to the disk. Various output formats are sup-
ported. Start streamer with '-h' for a list of options and supported output formats.
streamer will use the file extention of the output file name to figure which format to use. You need the -f/-F options only if the exten-
tion allows more than one format. If you get the "neither audio nor video format specified/found" message and don't know why, you can
enable the debug output (-d switch) to see what is going on.
You can safely stop the recording at any time with Ctrl+C. streamer will catch the signal and stop recording correctly (i.e. write movie
file headers) before exiting.
EXAMPLES
streamer -o foobar.jpeg
write a single jpeg file.
streamer -o quicktime.mov -f yuv2 -F stereo -r 12 -t 0:10
record a short quicktime movie.
