I recently published a post on Qt Labs Blog about using shader effects to transform video / viewfinder content in QML. http://labs.qt.nokia.com/2012/02/29/pimp-my-video-shader-effects-and-multimedia/
Strictly speaking, this isn't Qt5-specific: there is a version of the demo app which runs on Qt4 (using the Qt.labs.shaders plugin). But with the scene graph, the rendering path is optimised (decoder -> texture -> shader -> framebuffer), which should give better performance. And even if I say so myself, the demo does tick the cool box :) ---- Gareth Stockwell Accenture Global Mobility 20 Old Bailey London EC4M 7AN United Kingdom Tel: +44 7766 990156 ________________________________________ From: development-bounces+gareth.stockwell=accenture....@qt-project.org [development-bounces+gareth.stockwell=accenture....@qt-project.org] on behalf of [email protected] [[email protected]] Sent: 07 March 2012 17:57 To: [email protected] Subject: [Development] FW: [Marketing] Qt 5 alpha approaching Forwarding to the [Development] list since all the Qt 5 maintainers are here.

You can check with maintainers and I can check with marketing dudes.

Ok, I have started with http://wiki.qt-project.org/Qt_5 . I haven't been involved in any Qt release previously - bare with me and help improving the plans. (I wasn't sure about what wiki to use, if you prefer http://qt-project.org/wiki/ we can use that). Beef we need from the maintainers: - What modules are involved in the release. Essentials and which add-ons (if any)? - What are the highlights of each module. - What extra materials are availale: docs, code examples, screenshots, videos... - What areas in their module welcome more attention from testers, feedback, etc. Then we need to agree on the Qt 5 highlights. And how we promote them best in this Alpha release. All corners of the Qt Project are encouraged to find and contribute some spice to the release day. Can the MediaHub showcase some gerat visual features in an integrated way? Is someone making the most of the new QPA with some port? Is there some HTML5 beauty to show thanks to the new QtWebKit2? Any simple QtQuick 3D code generating amazing results? Anything running on a Raspberry Pi? You see where I'm coming from. If you are working on something cool and you can achieve an alignment with the Alpha release let us know here sooner than later. -- Quim _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development ________________________________ Subject to local law, communications with Accenture and its affiliates including telephone calls and emails (including content), may be monitored by our systems for the purposes of security and the assessment of internal compliance with Accenture policy. ______________________________________________________________________________________ www.accenture.com _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
