MPEG4 decoding of vlc streamed video

[minosander]

Hi everybody,
please let's read shortly:
I'm streaming mpeg-4 video (DivX) with vlc encapsulated in MPEG-2 TS. On the receiver site, I use my own receiver client which is actually DirectShow filter graph. As demultiplexor filter, I'm using that delivered within DirectX 9 -> Micorsoft MPEG-2 Demultiplexor. After demultiplexing, video elementary stream is passed to the downstream filter which is any divx decoder filter (e.g. ffdshow or DivX ). Unfortunately I don't see any rendered video from the decoder filters. When I render the same video locally, of course, it is played without any problems (AVI Splitter filter is used in this graph). I compared input for decoder filter in these both cases and found out that there are quite different. Then I tried to get just video PES from demux and then transform media samples to the ES (by removing PES headers). Decoder was then feed with such transformed samples. Such transformed video ES was almost the same as the AVI Splitter is producing when file was locally rendered. And once again, when I run the filter graph and deliver some samples to the decoder filter, the decoder filter always crashes:( And my Qs are:
1) Has anybody any experiences with such tasks?
2) Can be DivX/ffdshow/... sw decoder feed with video ES which is obtained by removing PES headers from vlc video PES in order they are coming from the vlc? Is there necessary to do anything additionally (since it's still not working:( )? Remind that correct DirectShow timestamps are set from PTS values and similar tests, but with mpeg-2 video, were successful.
3) Does the vlc use on win32 platform the DirectShow filters graph to decode video too?

Thanks in advance,
Milan
