Hi I'm using LTMM15 AxltmmPlayCtrl component in C#.

I want to hard code the DirectShow Graph for some items but I don't know how to do it.

I have all the DS filters ids and I tried unsuccessfully to achieve it with GetSubObject and GetSubObjectDispath.

I would be so glad if some could provide me an example.

Thanks in advance.

Jordi,
I'm afraid there is no way to build the entire graph yourself using our toolkit. Our controls will always add filters that are needed by the toolkit. However, you can control some parts of the graph such as the compressor, splitter, etc.

For example, you can choose the preferred splitter (Demux) for MPEG2 files using the IltmmPlay::put_PreferredMPEG2Splitter. You can also choose some other preferred filters (like decompressors) using IltmmPlay::SetPreferredFilter.

In LEADTOOLS Multimedia v15, there are some features that were not implemented yet. Some of these features are:
- Support for LAME MP3 Encoder.
- Flash Version 6 (FLV) with automatic recompression.
- Flash Version 9 (MP4/F4V) with automatic recompression.
