FlowMeter Filter

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:

Filter Results File Results Difference
Video Bytes 676218499 676048896 169603
Audio Bytes 45684072 45575168 -108904
Total Bytes 721902571 721985536 82965


The filter results come directly from the properties pages of the FlowMeter filters in the FilterGraph, the file results are from VirtualDub file information.
