• libav ffmpeg - streaming from both a mkv and input stream

  20 janvier 2020, par kealist

  I am trying to use ffmpeg libraries in C# with AutoGen bindings. The overall issue is that I am taking a collection of sources, some streams, and some .mkv containing recordings of a stream. As for now, they are all h264 and only video. For input streams, I am able to adjust the packets and broad cast them and that works fine, but any time I try to call av_interleaved_write_frame with packets from the MKV file, I get the error Error occurred: Invalid data found when processing input.

  Here is the main loop, where the error happens for mkv files. Is there an extra step ?

  /* read all packets */
  
  while (true)
  
  {
  
      if ((ret = ffmpeg.av_read_frame(ifmt_ctx, &packet)) < 0)
  
      {
  
          Console.WriteLine("Unable to read packet");
  
          break;
  
      }
  
      stream_index = (uint)packet.stream_index;
  
      type = ifmt_ctx->streams[packet.stream_index]->codecpar->codec_type;
  
      Console.WriteLine($"Demuxer gave frame of stream_index %{stream_index}");
  
  
  
  
  
      /* remux this frame without reencoding */
  
      ffmpeg.av_packet_rescale_ts(&packet,
  
          ifmt_ctx->streams[stream_index]->time_base,
  
          ofmt_ctx->streams[stream_index]->time_base);
  
  
  
      if (packet.stream_index < 0)
  
      {
  
          Console.WriteLine("Packet stream error");
  
      }
  
  
  
  
  
  
  
      ret = ffmpeg.av_write_frame(ofmt_ctx, &packet);
  
      if (ret < 0)
  
      {
  
          goto end;
  
      }
  
      else
  
      {
  
          ffmpeg.av_packet_unref(&packet);
  
      }
  
  }

  Anything need to be different for MKV files ?

  I get some contradictory error output where it claims it is annex b but also isn’t :

  [AVBSFContext @ 00000220eb657080] The input looks like it is Annex B already
  
  Automatically inserted bitstream filter 'h264_mp4toannexb'; args=''

  Verbose output from ffplay from an MKV file :

• Why i got an error with ffmpeg when i'm trying to merge 2 video file with the audio of a third video file multiple time in 1 line ?

  28 août 2020, par Niron

  I have 1 video file that i want to concat with an other video file using the audio of a third video file, and this 5 time in a line.
The only file that don't change is the first video file.
So i tried to run this command :

  


  ./ffmpeg.exe -i Video\\decompte.mp4 -i "Video\\Breaking Bad_OPENING_Opening.mp4" -i "TempVideo\\Breaking 
Bad_OPENING_Opening.mp4" -i "Video\\The 100_OPENING_Opening.mp4" -i "TempVideo\\The
