TestDataFilter is a Windows command-line application that tests the Data PID interface to the B2C2 MPEG-2 filter. The desired tuner parameters and data PIDs are set via command-line arguments.
Dump.ax (located in the B2C2 SDK\Filters directory) is a DirectShow filter required for running the sample Microsoft Visual C++ project Test Data Filter. The Dump.ax filter can be installed as follows:
Dump.ax
File dump filter Dump.ax is a useful debugging tool. You can build a filter graph using the Filter Graph Editor and connect the Dump filter to the output of a transform filter or any other output pin. You can also connect a tee filter and put the Dump filter on one leg of the tee filter and the typical output on another leg to monitor the results in a real-time scenario. Dump.ax uses base filter class CBaseFilter, rendered input pin class CRenderedInputPin, and the IFileSinkFilter interface.
Dump.ax is classified a "renderer” filter in that it has no output pins; it has only a single input pin, which is dumped to a file. Dump.ax prompts the user for a filename when it is instantiated and closes the file when it is freed.
Dump.ax is installed with the Microsoft® DirectShow® run time (a set of DLLs used for playing back supported media) and is available through the Filter Graph Editor when you choose Insert Filters from the Graph menu, and select the DirectShow Filters category. Microsoft® DirectShow® samples are part of the Microsoft® DirectX® Media Software Development Kit (SDK).
Run TestDataFilter directly from the command prompt by typing TestDataFilter followed by the required command-line arguments. Note: Settings provided are for example only. Actual Tuner and PID settings vary with the local network.
Satellite Example:
TestDataFilter -i s -f 12384 -s 20000 -l 11250 -e auto -o h -k 0 -d a/a -p0 0x1623
To run TestDataFilter from script, edit a *.bat file script such as run_tavf_sat.bat using required command-line arguments. Run the *.bat file by typing its name (run_tavf_sat.bat) at the command prompt.
