VideoDecoderKit

Version: 0.9.5

0.9.5: 修复推流音频问题。重构了一堆接口。封装了推流器VCRTMPPublish,可以方便推流RTMP了。优化了H264编码器，加入参数修改接口，便于推流时修改参数。简化删除了不同的Demo，去掉了Masonry依赖。同时提供静态Framework和动态Framework两种连接方式（考虑到苹果在iOS 13.3.1 中关闭了免费正式对动态库的签名，Demo使用静态连接）。

0.9.4: 实现RTMP，可以推流FLVTag了

0.9.3: 添加H265硬解码支持，支持播放H264 H265裸流

0.9.2.1: 添加macOS支持，删除多余的ffmpeg编译参数，添加播放FLV音频测试Demo。

videocodeckit's Issues

当解码过程（已初始化解码器），分辨率发生了变化，解码报错 kVTFormatDescriptionChangeNotSupportedErr -12916

分辨率变化了，是需要重新初始化解码器吗？

我现在是这么做的，每次获取 I 帧后，通过如下代码，获取分辨率信息，如果分辨率改变了，则重新创建 _decodeSession，不知道这样做是不是最佳方式？

// 1. 获取 videoFormatDescription
...

// 2. 获取视频帧的分辨率信息
            CMVideoDimensions dimensions = CMVideoFormatDescriptionGetDimensions(mFormatDescription);
            CGSize resolution = CGSizeMake(dimensions.width, dimensions.height);
            NSLog(@"视频分辨率：%dx%d", (int)resolution.width, (int)resolution.height);

// 3. 如果分辨率改变了，则重新通过 VTDecompressionSessionCreate 创建 _session
