Capturing to MPEG file

That worked quite nicely. Thanks!

Next question: I need to make captures that are suitable for VCDs. Currently I'm using VCDgear to convert the .mpg to a format that CDRDAO can use to write VCDs. The problem is that VCDgear is complaining that my captures do not have a "pack size" of 2324. How can I configure the Osprey capture filter to produce files that conform to this requirement?

It would also be OK to run a command line utility to massage the .mpg into the proper format. Do you know of any such utility? I can *not* used GUI based tools for this application.

In order to accomplish this you will need to use the "dump" filter, which is included with Microsoft's DirectShow SDK. The "dump filter" is not installed with the runtime, so you will have to build this filter yourself. The dump filter will write data to disk without requiring timestamps.

I need to capture from the composite video/unbalanced audio inputs to a MPEG file. I do not need a preview window. This is for a custom application, I can't use any of the standard capture apps.

I was hoping that I would be able to use GraphEdit to build the filter graph to do this. The naive approach "Osprey MPEG2 Capture" feeding "File writer" did not work. I get the error "The graph could not change state" "No time stamp has been set for this sample" (Return code: 0x80040249)".

What did I do wrong? Which filters should I use and how should I connect them together to be able to record a MPEG file?
