The compression options can also be set programmatically using the ILMMPEG2Encoder interface. The compression options for the LEAD MPEG-2 Encoder can be set manually through the encoder property page. See "Supplement 42: MPEG2 Transfer Syntax" and "Supplement 137: MPEG2 Transfer Syntax" of the DICOM specification for more information on requirements of the MPEG-2 SD or HD video. The DICOM files can store MPEG-2 SD or HD video. The compressed video data can be stored inside MPEG, AVI, DICOM or Ogg files with the option of saving the file with or without the audio data. The most common applications include DVD-Videos, SVCD and digital TVs. MPEG-2 is a high quality video compression algorithm and is best suited for applications with higher bit rates or high-bandwidth usage. MPEG-2 is the newer standard and has lower compression than MPEG-1 but the quality is much better than MPEG-1. MPEG-1 compression is used in VCD (video on CD). MPEG-1 is the older standard and achieves higher compression than MPEG-2 (but at lower quality). The LEAD MPEG-2 Decoder is a DirectShow® filter for decompressing MPEG-2 video data. Nevertheless, I wish to have same performances.The LEAD MPEG-2 Encoder Filter is a DirectShow® filter for compressing video data using the MPEG-2 (ISO/IEC 13818-2) or MPEG-1 (ISO 11172-2) standard. I don't know how VLC processes the video streams and maybe I don't have to. I didn't try with media player since I cannot start 4 instances.with GraphEdit (source->decode->render x4) : CPU 35%.with my program (release mode) : CPU 65%.

I tried do display 4 H264 videos (640x480) on the same screen, in 4 windows : There I read that my card should decode H264 if the right codec is installed (and I think it is since I'm under Win7).

In the same time, I've also posted a question on NVIDIA support forum about how to check H264 capabilities of a graphic card. This software, and I have good results (my card is compatible). I've checked the DXVA properties of my graphic cards with

Perhaps the EVR is still using a rending surface out of the graphic card (such as GDI things.). Here I would like to correctly set the configuration of existing filters. The docs you gave me are really interesting but they are almost better for a filter development.

I also tried to do the same to the output pin of the decoder which implies an error because (of course) there is no compatible interface. I can watch the videos but my CPU is still overloaded :-( Then no improvements of decoding performances.
