• FFmpeg avcodec_decode_video2 decode RTSP H264 HD-video packet to video picture with error

  29 mai 2018, par Nguyen Ba Thi

  I used FFmpeg library version 4.0 to have simple C++ program, in witch is a thread to receive RTSP H264 video data from IP-camera and display it in program window.

  Code of this thread is follow :

  DWORD WINAPI GrabbProcess(LPVOID lpParam)
  
  // Grabbing thread
  
  {
  
    DWORD i;
  
    int ret = 0, nPacket=0;
  
    FILE *pktFile;
  
    // Open video file
  
    pFormatCtx = avformat_alloc_context();
  
    if(avformat_open_input(&pFormatCtx, nameVideoStream, NULL, NULL)!=0)
  
        fGrabb=-1; // Couldn't open file
  
    else
  
    // Retrieve stream information
  
    if(avformat_find_stream_info(pFormatCtx, NULL)<0)
  
        fGrabb=-2; // Couldn't find stream information
  
    else
  
    {
  
        // Find the first video stream
  
        videoStream=-1;
  
        for(i=0; inb_streams; i++)

          {
  
            videoStream=i;
  
            break;
  
          }
  
        if(videoStream==-1)
  
            fGrabb=-3; // Didn't find a video stream

        {
  
            // Get a pointer to the codec context for the video stream

            // Find the decoder for the video stream
  
            pCodec=avcodec_find_decoder(pCodecCtxOrig->codec_id);

  When program receive RTSP H264 video data with resolution 704x576 then decoded video pictures are OK. When receive RTSP H264 HD-video data with resolution 1280x720 it look like that first video picture is decoded OK and then video pictures are decoded but always with some error.

  Please help me to fix this problem !

  Here is problems brief :
  I have an IP camera model HI3518E_50H10L_S39 (product of China).
  Camera can provide H264 video stream both at resolution 704x576 (with RTSP URI "rtsp ://192.168.1.18:554/user=admin_password=tlJwpbo6_channel=1_stream=1.sdp ?real_stream") or 1280x720 (with RTSP URI "rtsp ://192.168.1.18:554/user=admin_password=tlJwpbo6_channel=1_stream=0.sdp ?real_stream").
  Using FFplay utility I can access and display them with good picture quality.
  For testing of grabbing from this camera, I have a simple (above mentioned) program in VC-2005. In "Grabbing thread" program use FFmpeg library version 4.0 for opening camera RTSP stream, retrieve stream information, find the first video stream... and prepare some variables.
  Center of this thread is loop : Grab a frame (function av_read_frame) - Decode it if it’s video (function avcodec_decode_video2) - Convert to RGB format (function sws_scale) - Display to program window (GDI function SetDIBitsToDevice).
  When proram run with camera RTSP stream at resolution 704x576, I have good video picture. Here is a sample :
  704x576 sample
  When program run with camera RTSP stream at resolution 1280x720, first video picture is good :
  First good at res.1280x720
  but then not good :
  not good at res.1280x720
  Its seem to be my FFmpeg function call to avcodec_decode_video2 can’t fully decode certain packet for some reasons.

  Folks, I have the following ffmpeg command :

  I have just found out something regarding the files I will be processing with above command : that some mp4 files are video/audio, some mp4 files are audio alone and some mp4 files are video alone. I am already able to determine which ones have audio/video/both using ffprobe. My question is how do I modify above command to state what each file contains (video/audio/both).

  This is the scenario of which file has video/audio/both :

  video   time
  
  ======= =========
  
  Area 1:
  
  video1a    audio
  
  video1b     both
  
  video1c    video
  
  
  
  Area 2:
  
  video2a    video
  
  video2b    audio
  
  
  
  Area 3:
  
  video3a    video
  
  video3b    audio
  
  
  
  Area 4:
  
  video4a    video
  
  video4b    both

  My question is how to correctly modify command above to specify what the file has (audio/video/both). Thank you.

• Bring back support for CommonJS

  19 juin 2018, par bbc2

  Bring back support for CommonJS
  Browserify, which follows CommonJS module conventions, parses the AST
  
  for `require` calls to determine the dependencies of a project.
  jQuery File Upload used to support this ; it was removed in
  
  e2cda462610c776a1f7856692c98b1baab02231a when a new version of
  
  jquery.ui.widget.js was vendored.
