BMK MPEX card problem

I am trying to use VLS in combination with the MPEX card from BMK. I am using the drivers from bytesex.org with the patches for v4l applied. When I try to read from /dev/video1, I get a nice MPEG2 TS stream. However, when i try to use VLS to stream from /dev/video1 i get the following error:

[ERROR\kfir] Unable to start program video
[ERROR\kfir] Error: unable to start streaming of program video
Error: Unable to create thread
Error: Could not open file '': No such file or directory

I am using the vls.cfg file for the kfir card and the VLS version is 0.5.6.

Could anyone please help me with this? I have been trying for quite some time now without success.

almost the same problem ...

Hi,

we are also trying to stream the output of the MPEX card from the mpeg-2 device /dev/video1. No way ...
Is there somebody out there who can give an advice ?
I have found the following in the CVS changelog:
2003-08-14 Thursday 19:20 adq
* This change moves the precaching from InitWork() to DoWork() in tsstreamer.
The caching can take a while to finish on certain sources and I don't think
it should force the rest of vls to wait for it.

Also, with the MPEX MPEG2 encoder card (spits out a TS stream): If it gets no
video signal, it outputs no TS packets until it gets one. This causes VLS to
hang when starting this input until a video feed is plugged in.

...

So there must be a way to get the MPEG from the MPEX !
What´s the commandline for it ?

Hi, actually I found what caused my problem. In videoinput.cpp, on line 181, "device" should be changed to "filename".
