General Information
This DirectShow filter is for monitoring the data throughput of
a FilterGraph as it is running. It is designed to work with the
VirtualVCR application but it is also useable on its own to monitor
data throughput of a running FilterGraph in GraphEdit.
It has a simple properties page that is accessible when inserted
into GraphEdit as follows:
The filter will start with a value of zero for Bytes and Samples
and as samples and Bytes as passed through the filter the counter
keep track of the values.
Example with GraphEdit
The following is a sample with two FlowMeter filters in a
play back graph:
When run the filters will keep track of the samples and bytes
that pass through them.
Sample Results
Here are some sample results from the play back graph above:
