摘自@NanNan大佬的Potplayer 安装 LAV Filters 改善播放体验与质量
LAV的视频硬解配置中LAV Video Configuration有5种硬解码模式(Hardware Decoder to use:),如果没有特殊需要的话设置为 D3D11 即可,5种模式具体的解释如下:
D3D11(推荐):使用DirectX3D接口直接将数据输入给显卡的3D引擎,接下来的工作全部由显卡自行调度。由于没有其他奇奇怪怪的中转因此支持的格式是最多的,不会有显卡理论上可以支持却不能硬解的问题,并且画质几乎和软解一样好。不过因为除了显卡的解码模块外还用到了3D引擎,因此功耗会略大(其实也没高多少一点)
DXVA2 (native):为微软开发的硬件加速接口,解码完成的内容不经过内存中转直接渲染,因此能效比是所有里面最好的,缺点为限制极多且支持的格式很少,因此很容易因为硬解失败导致解码器回退到软解模式。
DXVA2 (copy-back):微软开发的硬件加速接口,解码完成的内容经过内存中转给渲染器,由于有回传动作因此能效比比上一个略差,优势为可以在解码器与渲染器中间添加滤镜,缺点和上面一个一样,支持的格式很少。
NVIDIA CUVID:Nvidia专用硬硬件解码接口,可以开启硬件去交错,现已基本弃用。
Intel QuickSync:Intel核显专用解码接口,CPU使用率比其余硬解模式稍高5~10%左右,可以开启硬件去交错,现已基本弃用。
在硬解模式设置的下方有一个叫 “Hardware Device To Use” 的选项卡,这是在电脑上有多个显卡的时候指定要用来解码的显卡,一般来说目前解码格式支持的最多的是 Intel,然后是 Nvidia ,最后是 AMD ,默认为 Automatic ,即软件自行指定。需要注意,如果手动指定设备,那么会自动回退到 Copy-Back 模式,因此除非软件选错了显卡,一般不更改。
I like what you guys are up also. Such intelligent work and reporting! Carry on the superb works guys I?¦ve incorporated you guys to my blogroll. I think it will improve the value of my site 🙂
