Any way to seamlessly switch between preencoded and live video?

[Whatsisname]

I want to do stuff sorta like a tv station, and be able to switch from preencoded video to live and back and forth and shit. Is anything like that possible?

[Jay]

you could try using camtasia but I have not tried this myself. There are no official tools for doing this.

thats what i was thinking i'll need to think of some way to haxor the input from a webcam or something so i can stick video ontop so i can switch to stuff

[_HF_]

set up a batch files which goes something like:

code:


:TOP

nsvenc cap:0,0 sc:<SERVERIP>:PORT:headers.txt



nsvenc cap:1,1 sc:<SERVERIP>:PORT:headers.txt



goto TOP

where cap:0,0 is your live source and cap:1,1 is your pre-recorded source (camtasia?)

then, in the command window when the file is running, all yuo have to do is hit ESC to switch between the two. (and use CTRL-BREAK to stop it altogether).

Also, one of the lines could be a different prog (nsvscsrc ?) for nsv file streaming.. etc etc..

HTH,

nsvenc and streaming with batch files is generally not a good thing, I have found that in transition some clients are locked out of the rest of the stream and must restart it.

yeah thats what i was worried about. Given i havent searched for more than 5 seconds for the source, but is the source for the NSV tools and stuff available? I could attempt to ghetto-rig a stream switching app.

[Jay]

nope

This is a early NSV encoder / streamer application written in dephi. ( Open source / GNU }

This might can help you with your video switch application.

A bit buggy on Windows 2000 and above. Works on Win98 SE.

What about, editing the shoutcast server to correctly relay NSV, run it as a local host relaying to your main server, and then just connect and disconect the live and preencoded sources to the local host , using it as a buffer to the main server. Does NSV react appropriatly to reconecting sources? Hmm, I guess, if it could you wouldnt need a buffer relay. oh well I'll shut up now, but it seems that could be an area to explore.

[Jay]

no, this will cause similar problems as the batch file trick.

There is a video DJ on Ranttv DJ Pulse who does a live show on the weekends. He is able to switch between a live camera and video files. He is also to switch between different cameras.

sounds like hardware

If your running usb web cams, you can use a simple usb switch to go from camera 1 to 2 etc.

I suppose you could use some thing like camtasia to go from live to encoded files.

I have the answer for you.. this will also let all of you asking howto stream mpg, avi, without pre encoding it.
The bonus?
Its Free.

http://www.splitcamera.com/ (preview seemed to work fine, but filter error on capture. Might work.)

http://www.softcam.com this one works and captures for me, and evenen animated watersmarks. thought he gui seems a little bubbly. It works for me thou.

Might ad more as i find them, try google for "virtual capture device"
