以下是实现代码,使用的ffmpeg是HarmonyOS ffmpeg编译链编译出来的ffmpeg。void rtmpPushManage::CGJCreatRtmpPush(napi_env env, napi_callback_info info) { avformat_network_init(); AVFormatContext *format_ctx = NULL; AVStream *video_stream = NULL, *audio_stream = NULL; const AVCodec *video_codec =...
AVFormatContext,AVStream,AVChapter,和AVProgram 可通过AVDictionary API 设置获取。 5 I/O read/write ffmpeg 不但可以读取本地文件,同时它还可以读取网络文件,市面上常见的流媒体协议它都支持(如rtmp,rtsp,http等)。同各种容器的媒体文件demuxers一样,不同的协议底层都需有相应的文件去实现,ffmpeg 有对各种协议...

1.2、调用AVInputFormat的read_header方法来尝试读取Stream的相关信息 intavformat_open_input(AVFormatContext **ps,constchar*filename,constAVInputFormat *fmt, AVDictionary **options) { AVFormatContext*s = *ps; FFFormatContext*si; AVDictionary*tmp =NULL; ...
Check these two functions. Setting flvflags to the options should work. int avformat_write_header(AVFormatContext *s, AVDictionary **options); int avformat_init_output(AVFormatContext *s, AVDictionary **options); Thanks, Guangyu On Tue, Jun 8, 2021 at 9:46 PM Mythili Vishalini Anbazhagan <...
