Does overlay plan support pixel level transparent (iMX6Q)

weishanli — Tue, 12 Aug 2014 10:24:16 GMT

This question is on iMX6Q platfrom, in case of use LCD panel which resolution is 1024x768 on SabreSD board.

I found a lot of demos on showing camera live view on fb1, but at that case, fb1 works under YUV mode and doesn't support pixel level transparent.

I'd like to show an icon on fb1 and let it float on main display.

Would you please tell me if framebuffer fb1, which known as "overlay", support partly transparent or not, if support, how can I change to this mode?

You may try using mfw_isink plugin, described in Appendix A (mfw_isink Usage)

of "i.MX_6_Series_Yocto_Project_Multimedia_User's_Guide.pdf".

Also, please refer to package with Linux Multimedia Codecs, which contains

Freescale Gstreamer plugins.
