需要加 -lmingw32  例如使用minGW32 ：执行g++命令：g++ -o mysql.exe main.cpp -lmingw32 -lSDLmain -lSDL main.cpp #include #include "SDL/SDL.h" #define WIDTH 640 #define HEIGHT 480 #define BPP 4 #define DEPTH 3

//定义目标音频参数 uint64_t out_channel_layout=AV_CH_LAYOUT_STEREO; //nb_samples: AAC-1024 MP3-1152 int out_nb_samples=pACodecCtx->frame_size; AVSampleFormat out_sample_fmt=AV_SAMPLE_FMT_S16; int out_sam

pFrameRGB=av_frame_alloc(); int numBytes=avpicture_get_size(AV_PIX_FMT_BGR24, pCodecCtx->width, pCodecCtx->height); out_buffer=(uint8_t *)av_malloc(numBytes*sizeof(uint8_t)); avpicture_fill((AVPict
