• iOS local host RTMP server

  16 septembre 2020, par estoril

  I have been tasked with creating an iPad application, iOS 12.3 latest support, to run as a local RTMP server. Purpose being, external devices connect to this local RTMP server on iOS iPad, either via the iPad's wifi connection or enabled hotspot, and playback the display of external devices (mirror) onto the iPad.

  


  I have been successful with creating a local host HTTP server, but upon connecting with external devices the local server on the iPad quits.

  


  I will be using open source software for decoding and playback of video feed such as vlc or ffmpeg, but need guidance on an iPhone local host implementation, such as https://github.com/sallar/mac-local-rtmp-server for a mac.

  


  Any help would be greatly appreciated !

  


• How to use AVPacket as local variable(or said temporary variable)

  27 août 2020, par pango

  my program receive a aac audio stream from net,and use ffmpeg to decode the stream,so I must pack the stream data to a AVPacket struct,I use a local variable to do this, the code like below :

  


  bool OnRecvAACStream(const char * audioDataPtr,int audioDataSize,int64_t tBeg,int64_t tDura)
{
    AVPacket pkt_tmp;   // local varible
    av_init_packet(&pkt_tmp);
    pkt_tmp.data = audioDataPtr;
    pkt_tmp.size = audioDataSize;
    pkt_tmp.pts = tBeg;
    pkt_tmp.duration = tDura;
    
    if (avcodec_send_packet(m_codec_ctx, &pkt_tmp) < 0)
    {
        assert(false);
        return false;
    }
    while (avcodec_receive_frame(m_codec_ctx, m_dec_frame) == 0)
    {
       // read out dec audio data
       ...
    }
    
    retur true;
}



  


  I just use av_init_packet() to init the local varible, av_packet_unref() and av_packet_free() are not called,so is it valid ? is there any memory leak problem ?
