Hi Mike,
yup right now it'll work from an attached device as Stephan said
but in addition including a capture card, provided the device has
a quicktime driver installed. When I wrote the live feed extension
part of the work included support for a stream, however I did not
get that far and the capture card was sufficient for the client.
I wrote some documentation for the ".live" processing that Robert
asked me to put on the wiki - so I should do that tomorrow if you
think it would be of use to you. Are you on Windows or Mac BTW?
Since you asked about the ".live" then A=as a ten second piece of
documentation off the top of my head start by using a slightly
modified osgmovie app until I submit the osgvideo example:
0. Modify the osgmovie.cpp and make sure that the .live
extension is associated with the osgdb_qt plugin:
osgDB::Registry::instance()->addFileExtensionAlias("live","qt");
1. run osgmovie --devices
If you have any live feed devices associated with a QuickTime
driver then this will spit out some command line options and
associations.
eg: ...
4:1.live Blackmagic HDTV 720 Intensity HDTV 720p 59.94
...
2. run osgmovie x.y.live
This will force load the osgdb_qt plugin, and then attempt to
open the x.y.live where x and y are the input and channel of
your input - eg 5:0.live
Sorry I can't help you regarding the streaming using QuickTime
at this point in time.
Cheers,
Colin.
