流媒体协议的图挂了，显示不出来

attribute_deprecated AVFrame *coded_frame

This is an outdated property that has been reported as unusable
#if FF_API_CODED_FRAME
/**
* the picture in the bitstream
* - encoding: Set by libavcodec.
* - decoding: unused
*
* @deprecated use the quality factor packet side data instead
*/
attribute_deprecated AVFrame *coded_frame;

I帧是帧组GOP的基础帧(第一帧),在一组中只有一个I帧;？

你好。从定义来看，每个GOP的第一帧应该是IDR帧吧；每个GOP中应该是只有一个IDR帧，普通I帧可能不止一个。

nvcodec 编码的文件问题

FILE* inf = fopen(argv[1], "rb"); FILE* outf = fopen(argv[2], "wb");

inf 是不是 420的yuv文件？
outf 是不是h.264文件？
