vcap-mgr

Runs on:

QNX OS

Options:

-c filename

Specify filename as the absolute pathname to the configuration file with which vcap-mgr will use to start (e.g., with pre-loaded drivers). For example:

# vcap-mgr -c /etc/vcap-mgr.conf
                

See vcap-mgr commands for all the valid commands that you can specify in the configuration file.

Note:

If you specify this -c option, you must start screen prior to starting vcap-mgr.

If you don't specify this -c option, vcap-mgr will not load any capture driver when it starts.

-v verbosity_level

Start vcap-mgr with a level of debugging messages specified by verbosity_level (an integer in the range [0..4]). The level of debugging messages increases from 0. Each debug level includes log messages for that level and all messages from previous levels. If you don't specify this -v option, vcap-mgr uses the default verbosity level of 0 (zero). You can use the slog2info utility to view the system log for errors and messages.

Debug level	Message types
0	Error messages Note: If errors occur while vcap-mgr is starting, the error messages are your console; otherwise, you can see the errors with the slog2info utility.
1	Warning messages
2	Informational messages
3	Debugging messages
4	Detailed debugging messages

Note:

Any verbosity level above 1 may impact the performance of vcap-mgr. You shouldn't consider higher levels of debugging on a production system.

Description:

The vcap-mgr utility enables you to load and unload multiple capture drivers on-demand. It also allows input frames from a video capture library to multiplex into multiple Screen streams and/or Screen windows.

After you start the vcap-mgr utility, it provides mount point (/dev/vcap-mgr/command) as an interface with which you can interact via specific commands.To run vcap-mgr on your target, simply run vcap-mgr from a shell.

See vcap-mgr commands for more information on how to use commands to interact with the Video Capture manager.
