基本思想是:先把字库中的文字叠加到图片buffer上,叠加的时候如果能先得到背景的现在图片,最好了,就可以取反,这样任何光线环境都可以看清文字。
然后再把这个图片以图形层的方式叠加到输出的主高清通道HD0上即可。
中间生成文字图片的过程一次完成,可以在线程内执行,通常每秒处理一次即可。这样就可以实现OSD时间,各种文字信息的叠加。
我这边实现的是整个Debug调试信息的叠加,有20行。
由于代码在我的整个项目内,还没有搞清爽,所以摘主要关键的传上来大家参考。
其他的部分,参考SDK里面的那个叠加llogo图片的例子,注意把背景色都弄成黑色0x0即可,透出输出的视频了。
附件中,有汉字的字库,本文仅仅使用HZ16Lib.c即可,直接添加到自己的工程里就可以了。如果嫌弃自体小,还可以找24或者32的字库,基础图片可以小一倍,然后叠加时,对缓冲进行放大,要用到那个TDE处理一下缩放,这样效率高些。
我这边输出现在是1024*768,图片用的也是1024*768,所以没用TDE缩放,效率没问题,3520速度很快,我叠加了20行debug信息,都没事,每秒才处理1次。
