H264与AAC ES打包成MP4

大家好，欢迎来到IT知识分享网。

注意

设置图像的sps pps

MP4AddH264SequenceParameterSet(file,video,sps,sizeof(sps));

MP4AddH264PictureParameterSet(file,video,pps, sizeof(pps));

设置音频解码信息

MP4SetTrackESConfiguration(file,audio,pConfig,configSize);

MP4FileHandle file = MP4CreateEx(“new.mp4”);//创建mp4文件
    if (file == MP4_INVALID_FILE_HANDLE){
        printf(“open file fialed.\n”);
