[meta-freescale] [for-daisy][PATCH 2/8] qtmultimedia: Add support for i.MX6
Otavio Salvador
otavio at ossystems.com.br
Wed Jun 4 14:09:08 PDT 2014
This patch implements GStreamer-buffer to OpenGL-texture for i.MX6
allowing fluid video-playback up to 1080p with very little CPU load.
The patch has been backported from Qt 5.3.

+adding zero-copy-QSGVideoNode for imx6
+
+On imx6 there is a platform-specific API to implement
+memory-mapping from gstreamer-buffer to opengl-texture.
+
+This plugin uses this API to avoid CPU-based-memory-copy.
+
+This allows fluid video-playback up to 1080p with very little CPU load.
+Before even 720p used one cpu-core completely and wasn't fluid.
