最近在买机顶盒和电视,别人送了个盒子我暂时用着试试。

测试平台:
安卓,芯片S905x3,运行内存4GB,10bit色阶素材,remux4k素材,DTS和DTSHDMA音频
,安卓自带的硬件监测。功放,音箱等。


结果和讨论:
--- MXplayer pro和Plex和KMplayer都不能音频透传,直接卸载,Plex选项里只能支持
到eac3,不能传无损.
---偏重DTS系的用户,应该上shield试试,貌似没有我遇见的问题。而且普通版2G内存
shield应该够了。
---Kodi自带的音频分割器挺不错的,突出了DTS有损和无损的巨大差别。用音量简单判
别透传成功,功放也能点亮无损指示灯和HDMA。
---盒子播放4k文件的流畅度跟电脑差不多,70多GB的一个文件都可以随便拉进度,都
远比我8GB内存的手机好,也比电视自带系统好。感觉机顶盒能代替很多电脑事物,试
了购物应用,越看越想买,因为看大图至少比手机和笔记本电脑舒服。
---不知shield上其他APP是否支持HDR10plus。kodi至今不支持。但是可以提前转化成
SDR按这个链接的方法:

devices/
---不知remux的HDR10plus,是怎么得到的?按理应该是从杜比视界(DV)播放时录的
,而不是直接提取转化。除非他们知道破解DV的参数?
---惊喜的是kodi安卓居然直接支持10bitRGB输出(不知道苹果盒子是否支持),以前
PC版要靠插件才有这功能。VLC 不及格,但也许起因是盒子不兼容VLC。
---kodi和安卓和shield依然不支持指定亮度的HDR转化(不知道苹果盒子是否支持)。
所以我暂时不买shield。
---听说shield有自己的AI渲染器,画质比苹果盒子要强。不知kodi或者安卓是否有开
源社区的渲染插件?以后有空找找。


结论:
如果主力是电视机,那么买个一般的大牌机顶盒的画质已经够用,选个兼容HDR10和Rec
.2020的电视机即可。如果主力是投影机,要么用电脑上的专业播放软件,要么投更大
屏直接用Kodi机顶盒降到SDR。DV没啥意义,投影机连HDR10plus都不理。普通蓝光机的
硬盘播放也不如机顶盒,除非松下那个旗舰,可以指定亮度的HDR转化。有了电视机顶
盒和NAS,家里不需要太多的笔记本和电脑。
