能进行V4L2下的视频采集保存,如果通过OMAP自带的模块实现视频图像透明度的变化,该查阅和修改哪些驱动代码?
网上的资料好少,想问下Omap是否也和DM6446等一样有VPSS的视频处理子系统。如果要实现osd功能,是否有Osd模块来做呢?
新手请求帮助,谢谢大家

谢谢你的关注!
我之前记了wiki上TI的某一个地方有:OMAP35x also has a 3-layer built-in OSD manager which is a little different than the one on our DaVinci processors which support more than 3-layers.应该也是能实现的,我再看看DEMO吧。
另外,我这在看http://processors.wiki.ti.com/index.php/UserGuideDisplayDrivers_PSP_03.00.00.05里面就讲到阿尔法模式,请问你能给我再介绍点其他关于阿尔法模式的资料吗?我希望能看到有个简单的小例程的,非常感谢你的帮助!
