    <gsachin> so this is done and the status is that it is being discussed between STE Legal and Joe Bates

    <gsachin> until copyright assignment is finalised

    <sudipj> I have mailed him to review the app

    <gsachin> ok

    <gsachin> moving on

    <gsachin> gsachin to discuss uds attendance with Linaro MM WG engineers

    <gsachin> so I know the status for most

    <gsachin> mkum : any further update

    <gsachin> mkum_ : any further update

    <mkum_> i have libjpeg-turbo working on OMAP4 now

    <mkum_> with optimized NEON functions

    <gsachin> ok

    <mkum_> There were some issues Tom was facing and I helped him with that

    <gsachin> I am asking about update on your travel to UDS

    <mkum_> oh

    <mkum_> about that it seems very difficult to get Hungary's visa

    <gsachin> ok

    <mkum_> Based on my talk internally I think I won't be able to attend UDS

    <gsachin> ok

    <gsachin> thats the case for most of people

    <gsachin> yes

    <krtaylor> more details will follow

    <gsachin> action : wayne to check if eglsink could be merge into gst-plugin-gl

    <wayne> I mailed to Julien, author of gst-plugins-gl for GLES2 compile problems. And he said he would resolve this in next weeks.

    <gsachin> but what I saw from your code

    <gsachin> that you are using some freescale specific extensions

    <wayne> I'm building environment for the gst-plugins-gl, it depends on gstreamer 0.10.32

    <wayne> My environment now is lucid

    <wayne> I'm discussing with him about the extension

    <gsachin> that is fine but it seems from your code that you are using some proprietary egl extensions

    <gsachin> and if we need to propose some extensions then khronos is right place

    <wayne> Yes. No standard interface exists

    <gsachin> ok lets discuss this later

    <gsachin> moving on

    <wayne> ok
