I want to capture cc(closed caption) as plain text to text file; using directshow, graphedt.

I have used VBICodec and Dump filter. My graph is as follow

Ospray Capture Device (has 4 output pin:Capture, Preview, CC, VBI) -> Tee/Sink-to-Sink

Converter -> VBI Codec -> ClosedCaptions.txt(dump filter).

the file has encoded data and not the plain text.

how can i save closedcaption to text file ? (i have windows 2008 server)

The Osprey (and likely any other capture card that supports NTSC and ATSC captions) outputs EIA-608 format. It has special character sets and control codes that have to be converted to whatever format you need.

Unfortunately I don't know of any readily available DirectShow filters that will convert this to a text format for you so you'll probably have to write one.
