OK，I have translated the readme into English and added readme_cn for Chinese.

push_frame前处理就好了，已经是解码后的帧

The scaling of picture caused distortion, I changed GL_NEAEST => GL_LINEAR，this can help to reduce distortion, although it consumes more computing resources. See HGLWidget.cpp: ``` glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER,...

ffplay uses ffmpeg and sdl，sdl uses d3d on Windows，OpenGL on Linux. OpenGL cross-platform, but d3d is more efficient on Windows. If set dst_pix_fmt = BGR24, sws_scale convert yuv -> rgb...

Set `draw_fps = false` when you test.

Maybe we can try to integrate SDL into hplayer, renderer is too complex.

Try hplayer.conf `renderer = sdl`

Add `HV_STATICLIB ` to precompiled macros to avoid hexport.h dllimport.

我仔细看了你的提交，非常的精彩，适配了udp connect和多线程收发一个udp端口，并且还添加了IpHash的负载均衡策略，看的出你对libhv掌握的很深。 但是我感觉这个PR不太适合合入主分支（目标适用人群很少，增加了代码复杂度），udp connect的方式不常用，另外udp和tcp不同，udp server只有一个fd，用一个IO线程专门收就够了，然后放入消息队列，用线程池去消费，这样的多线程模型更合理易懂些。

我就代码风格和命名上添加了一些评论，这个PR后续是否会合入还不确定，需要给出udp connect这种方式的优势和适用场景
