 Description  « Hide
Sub task to implement streaming audio via gstreamer.

OpenAL itself does not support streaming and it is fairly trivial to hijack the existing streaming media class and give it a URL of an audio source and it just plays fine.

Note the gstreamer patches on VWR-2662 are now broken on 1.19.1, new ones will appear on this JIRA.

Basic issue is that audio is now initalised before gstreamer DSO symbols are loaded so trying to create a private instance of LLMediaImplGStreamer crashes on viewer startup. Solution init the streaming audio after the symbols are loaded.

Comment [ I'm trying to compile the OpenAL patch on Windows using VC8, but I get:

c:\Projects\linden\indra\llmedia\llmediaimplgstreamer.h(44) : fatal error C1083: Cannot open include file: 'gst/gst.h': No such file or directory

Is the gst package available for Windows? I've checked out the whole 1.20.6 source code with SVN, but sofar it doesn't seem to be able to build. ]
