here you have the file:

However, we are trying to implement the recording graph in a C++ library. We have found that using GraphEdit we can record without problems but when we try to code this, we cannot match the Mux Filter with the file writer (nor the Ds File Writer, neither the Solveig MM file Writer).

 HRESULT: 0x80040217 (2147746327)
Description: No combination of intermediate filters could be found to make the connection.
Severity code: Failed
Facility Code: FACILITY_ITF (4)
Error Code: 0x0217 (535)

Thank you!

Hi Dmitry,

First of all, thank you for the immediacy of your response.

We have tried the Axis H264 Video Decoder and ffdshow Video Decoder and we have obtained the same result.

Where could I upload an example file?

Best regards,

We are developing an application in order to save live streaming video.

We are using the directshow filters SolveigMM File Writer and SolveigMM Matroska Muxer and we are trying to record Axis cameras H264 video streams.

We make the directshow graph RTSP Source --> SMM Matroska Muxer --> SMM Filewriter and we craft properly the .mkv file but when we want to playback, we only can play it with the VLC application. If we want to play the resulting file with directshow we can construct the graph without problems (file source --> SSM Matroska Splitter --> Video Renderer), we can do the play action, but we get a black screen all the time we are playing the video.

Is there any reason for that?

Thanks in advance!

Javier Almendrote
