NAME
jpeginfo - prints information and tests integrity of JPEG/JFIF files. SYNOPSIS
jpeginfo [ options ] [ filenames ] DESCRIPTION
jpeginfo is used to generate informative listings of jpeg files, and also to check jpeg files for errors. Program also supports automatic deletion of broken jpegs. OPTIONS
Options may be either the traditional POSIX one letter options, or the GNU style long options. POSIX style options start with a single ``-'', while GNU long options start with ``--''. Options offered by jpeginfo are the following: -c, --check Check files also for errors. (default is just to read the headers). -C, --comments Display file comments (from COM markers). -d, --delete Delete files that have errors. (default is not to delete any files). -f<filename>, --file<filename> Read filenames to process from given file. To use standard input (stdin) use '-' as a filename. This is alternative to default where filenames are given as parameters to the program. -h, --help Display short usage information and exits. -5, --md5 Calculates MD5 checksum for each file. -i, --info Displays even more information about each picture. Prints image coding (Huffman/Arithmetic), density (in dpi/dpc), and whether CCIR601 sampling was used or not. -l, --lsstyle Uses alternate listing format (ls -l style). -v, --verbose Enables verbose mode (positively chatty). --version Displays program version. -q, --quiet Quiet mode, output just the jpeg infos. -m<mode>, --mode=<mode> Sets the delete mode, meaningful only when used with -d flag. Mode can be one of the following: all files containing any type of errors/warnings, not necessarily preventing the decoding. (default) erronly only files with serious errors (ie. cannot be decoded at all). BUGS
None, so far :-) SEE ALSO

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. SEE ALSO
