I think it will be a great feature to use a remote camera as if it was directly connected to the computer where Virtual Dub is running. As in another video programs as Quick Time where you can connect to a URL and the image is shown in the program's interface. Will it be possible with Virtual Dub?. I'm thinking about a few ways to do it so that I can help with the development, but I'm not totally sure. |

I'm not a developer, but to me it seems the cleanest way to do this would be to write a DirectShow driver that does this, and let VirtualDub simply access this in capture mode.

I wonder if DirectShow might already support this with one of its input filters. If so, then it might just be a matter of setting up the DirectShow graph differently.

I'm not sure of how to do it. I'm searching the web in order to look for the directshow filters to check if this feature of the IP driver is included, but there is nothing new in my search right now |

You can try downloading Media Player Classic and see if its Open URL function works.

It seems to work, but how can we use it to add the feature to virtual dub? I think it will be a great option for the capture mode. |

It involves modifying the DirectShow capture module to use a URL input filter instead of a capture filter. I'll have to look into this.
In the meantime:
- What protocol does the URL use? IOW, does it start with rtp:, http:, ...?
- What format does the camera produce? MJPEG, MPEG, H.264?

I have taken a look at different kinds of IP cameras searching the way to open them in Virtual Dub. Some of them use HTML to send the requests, others use FTP and, the most, use javascript. I've checked cameras with direct video transmission too. Maybe there is a unique way to do all of this in virtual dub... |

After a break, I've returned to work on it.
May RTSP be a good way to do it?
I'm taking different ways and the new cammera I'm testing has this option to transmit video. This cammera also allows to use Universal Plug and Play, so it's possible that the system detects the device and loads it as any other device supported in virtual dub.
Checking the transmission of the device, the video streaming uses this address to send the images, without the cammera's interface "http://IP_ADDRESS:PORT/video.cgi?resolution=CIF&random=0.8531384908443218" Maybe we can use it to load the images into the Virtual Dub's main window
I'm a little bit lost anyway, because I'm looking software as Real player and some related programs that allows IP connections so that the video appears in the main window instead of doing in a web browser. |
