• ffmpeg : Convertion to mkv with compatibility with Samsung BluRay

  25 octobre 2018, par Yehor

  I have several videos (FullHD resolution) which I want to convert to mkv format and play on my Samsung BluRay Player (model BD-J5900).
  Based on User Manual (http://media.datatail.com/docs/manual/252846_en.pdf , page 6) it supports mkv playing if codecs are :

  • Video : H.264 BP/MP/HP
  • Audio : MP3

  Thus, based on https://ffmpeg.org/ffmpeg.html the command to convert it into proper format is :

  ffmpeg -i input.avi -f matroska -vcodec libx264 -acodec mp3 output.mkv

  It converts, but file is not playable on player. It say "Video format is not supported".

  After checking info here : https://trac.ffmpeg.org/wiki/Encode/H.264 - I thought it may require some compatibility and change the command to :

  ffmpeg -i input.avi -f matroska -vcodec libx264 -profile:v baseline -level 3.0 -acodec mp3 output.mkv

  But it also didn’t help - player demonstrates the same error.

  How to fix that ?
  Thanks !

  Updated :
  Also tested following options

   ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -x264-params bluray_compat=1 -acodec mp3 output.mkv
  
   ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -profile:v high -level 4.2 -x264-params bluray_compat=1 -acodec mp3 output.mkv
  
   ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -profile:v baseline -level 3.0 -x264-params bluray_compat=1 -acodec mp3 output.mkv
  
   ffmpeg -i input.file -vcodec libx264 -vf format=yuv420p -preset veryslow -acodec mp3 output.mkv

  Also not supported.

• 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++)

  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.

• How to use ffmpeg to copy streams and preserve format and metadata ?

  24 septembre 2023, par dzeek

  I have two files with multiple streams in each.

  



  Output.mp4 has 2 streams : video and audio (streams 0,1)

  



  Input.mp4 has 3 streams : video, audio and data (streams 0,1,2)

  



  I need to add stream 2 from Input.mp4 to Output.mp4 yielding Final.mov.

  



  I tried using this command but it does seem to preserve the format and metadata for the stream that is added :

  



  ffmpeg -y -i Output.mp4 -i Input.mp4 -c copy -map 0:0 -map 0:1 -map 1:2 Final.mov


  



  The output from ffmpeg seems to show that it is working but the format and metadata for the streams in the Final.mov is not correct.

  



  I would appreciate any help with how to change the command to make it work.

  



  Thank you !

  



  Here is the command output :

  



  ffmpeg -y -i Output.mp4 -i Input.mp4 -c copy -map 0:0 -map 0:1 -map 1:2 Final.mov
