I developer a myparser.au filter which will take upstream from {&MEDIATYPE_Stream, &MEDIASUBTYPE_NULL} and do some parse to ensure that is my media type.
In graphedit, I can open my media file(test.abc) using "file source async" filter, and point it to my "myparser" filter.
The problem down to how can i make the graphic automatically use "file source async" to open my file and point it to myparser??
I have try in regedit adding MEDIATYPE/extensions/.abc adding source filter with guid of my myparser?(Although I know it is not a source filter, and is doesn't work.)
1) So can I skip the process of writing my own source filter and use the "file source async" instead?
2) If Q1 is yes, which GUID I should use in the registry of the .abc extension
3) How to less graphedit know that the .abc is needed to be parse by the "myparser" filter
3)
