The VideoLAN Forums

Hello,
We need to buy one of hour of consulting/guidance time from a VLC expert.

Specifically, we need to know how to sout a RTSP input as a direct show device to be used/seen by Flash Media Live encoder (or other windows desktop app like Skype).

If you feel that what i require is possible, and can help, please contact me.

We will pay via Paypal.

Thanks
Sean

Did you have a look at

Jean-Baptiste,
Thank you for the reply.

If i understand the sensoray VLC code, it seems it that the code is to make Sensoray framegrabber products appear as show inputs to VLC.

Our requirements is to transcode ANY inbound stream on the VLC input into a DirectShow sout type stream thus enabling any IP camera to be a DirectShow device (via VLC)

I am not a videolan or video streaming expert, and i to not understand directshow, so my terminology may be incorrect. In which case I am sorry.

Adobe's FMLE (Flash Media Live Encoder) will only recognize DirectShow devices (like a USB web cam). In our application we have IP cameras on the network with FMLE, but they only stream OUT using RSTP (or MP4, MJPG, or H.264). So we need to transcode that IP camera so that it looks like a local USB camera and thus recognized by Skype or Adobe's FMLE or Movie Maker..

Any other suggestions would be greatly appreciated.

Thanks
Sean

The last post mentions a (non-free commercial) program called VCam, which can be used as a virtual webcam that things such as FMLE recognises. There's a VLC to VCam plugin for VLC which ones selects as a video output module. VCam can then use VLC as an input, and hence be used to stream to FMLE etc.

That's presumably just for video only - for audio there is a Virtual Sound Card product, but it may be doable without that.

So (if that works) there's a potential non-free solution.

EDIT: There's also an RTSP/RTP DirectShow source filter here:
http://sourceforge.net/projects/rtspdirectshow/

That could be used with RTSP streams directly, or perhaps with VLC streaming out via RTSP. Note the source code only is provided, however there's a binary of a RTSP source filter (possibly a different filter) here.

That by itself won't work as there needs to be a capture device that things like FMLE can see. Here's a link to an example source filter masquerading as a capture device:

Perhaps not what you're looking for though.

Finally (add http - max URLs in post reached):
alax.info/blog/1223

^If that works it can be used in conjunction with VLC which can stream M-JPEG over HTTP.

END OF EDIT.

Arite,
thank you for the thoughtful reply.

We have already tried vCam. The problem we had with it was too many transcoding processes running: RTSP > VLC>vCAM > FMLE > out to content delivery network. This really taxed our low end host and peaked at 100%. So we did not want to move forward with it.

We could try your suggestion for building our own from open source.. But that is beyond our scope.

We have already tried Alax.info. His solution is great and works with certain cameras for http streaming and does not require anything else, as it exposes the camera as a directshow device visible to FMLE. But we were not successful with RTSP and it was not a universal solution.

Thanks again for your suggestions and support.

Kind Regards
Sean
