Comment on DirectShow Video Source Filter for JPEG and M-JPEG IP Cameras by Roman

Great news: x64 build is also available, see http://alax.info/blog/1223

I have bits of code to build RTSP filter also, but this goes slowly as a low priorty thing.

Dear Roman,

Thanks for nice Directshow source filter, the only problem is that it works only with 32 bit applications but I have a 64 bit application and it did not accept it, could you also make the 64 bit version.
Also as a suggestion if it can accept RTSP URLs I thenk it will be ideal.

Comment on IP Video Source: Pure JPEG URLs and Software Version by Roman

If you put your camera online and email me it’s IP address, port, admin/username, vendor, model (believe it or not, sometimes you cannot figure out model through web interface; and also this time I know it is Panasonic WV-SC385), I can take a look if it can be set up with my library.

Without this, you one normally checks this out with vendor’s HTTP/CGI reference and/or using network sniffing tools.

Hi!
We are finding that the Alax.Info JPEG Video Input Devices could match our requirements.

We need to broadcast from a network camera using Microsoft Expression Encoder to use its smooth streaming feature.

The 1st problem is that MEE does not accept urls as live source. At this point your app makes the trick as when configured, it exposes new live sources to MEE and works fine.
The test has been done using an AxisP1346 camera and is is ok (http://user:pwd@ip/axis-cgi/mjpg/video.cgi?resolution=640×480&camera=1&compression=25).

The problem is that the production environment has Panasonic WV-SC385 cameras and has not been possible to configure them in a proper way to make the JPEG video source accept its stream. Neither is this stream accepted by the WMP, so I suppose that non standard mjpeg is broadcasted by these cameras. On the other side, VLC does recognizes this stream.
So several alternatives spring to mind:

- One attempt now would be to make VLC broadcast the Panasonic input stream in such a way that could be valid for your JPEG video source. Which settings should we use for this to be ok for your app?
- Another would be using a different filter that accept the Panasonic stream, but how could we expose it to Microsoft Expression Encoder?

Regards

Well, you can have both 32 and 64 bit spy registered – they don’t interfere. What you need to switch is 32/64 bit version of GraphEdit (Graph Studio) and also UAC-ness of the target application being spied.

Just in case anyone else is confused as to why they can’t see their system-wide graphs showing up in GraphEdit (or similar); you may need to switch to either the 32 or 64bit builds of DirectShowSpy.dll depending on the application generating the graphs.

Runs great in Windows 7, both Win32 and x64 builds.

Comment on Utility Clearance: Rasterize Font by Roman

Roman — Sat, 26 Nov 2011 09:21:10 +0000

Where does the program get the .TTF file to process, lets say when specifying the statement “Face=Times New Roman” in the .ini file; what will the program do to find the Times New Roman font file?

It takes a Windows font through Windows API. So it can be any font registered with Windows, such as residing in \Windows\Fonts or available through name mapping.

What does the statement “Weight=1024″ in the .ini file do?

Refer to MSDN http://msdn.microsoft.com/en-us/library/dd145037%28v=VS.85%29.aspx “lfWeight” constants.

Just FYI, I am using windows XP to activate the DOS window in order to activate the rasterizing program.

It is a Windows application, you can run it directly too.
