About two months ago I informed the followers of this blog that I will now be working on SPICE project for Red Hat . Judging from the questions I was asked after that, I realized that not many people know about SPICE so I thought I write at least one blog entry dedicated to explaining what SPICE is all about. Before I get to SPICE itself, let me first introduce you to the world SPICE lives in. Virtualization and Virtual Machines (VMs) For some reason, I feel that I should leave the definitions to wikipedia and only quote it so that is what I am going to do: " Virtualization, in computing, is the creation of a virtual (rather than actual) version of something, such as a hardware platform, operating system, a storage device or network resources. " " A virtual machine (VM) is a "completely isolated operating system installation within your normal operating system".Today, this is implemented by either software emulation or hardware virtualization ". V...
After I was informed about the existence of ClutterGstVideoSink, I quickly modified my super-video application to make it use that. But as soon as i did that, i stopped getting even the static image. After careful analysis for days, I figured that I was supposed to call gst_bus_add_signal_watch() on the pipeline bus since ClutterGstVideoSink uses messages on the bus combined with signal handlers to render the frames in the application thread. This is obviously a 'dirty' hack; a hack because gst elements are supposed to do all the media processing in the pipeline thread, dirty because gst bus is not meant for media transport. After this realization, I had been working on it from time to time. First I tried to make the actual rendering happen in the gst pipeline thread by using the clutter's thread safety primitives and that worked quite nicely in the end except for one minor problem: The call to clutters rendering thread blocks if it happens after the clutter main loop has b...
I am no more a fan of Ubuntu. The reason is their recent demonstration of lack of community spirit. Here is the release announcement of Ubuntu hardy alpha6. If you scroll-down you can see the gnome-system-monitor's new cool "Resources" view featured with a nice screenshot. Since Karl-Lattimer worked really hard to make this happen, he asked to be given personal credit on that page. Don't know about others but I see this as a very reasonable thing to ask. The result of this request can be seen in the announcement of hardy beta. They just removed the feature from the announcement. Shame Ubuntu shame. UPDATE: It's interesting how most of the comments that are from people who got pissed without actually caring to understand the main point of this blog entry (which me and Karl-Lattimer tried to emphasize in the comments) are posting as Anonymous. :) Acknowledging the possibility that they might not think comments are worth reading before commenting, let me make it c...
