• 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=''

• FFMPEG php HLS and DASH conversion

  21 juillet 2020, par Angus Simons

  I'm using this repo https://github.com/aminyazdanpanah/PHP-FFmpeg-video-streaming to encode video in hls and then reproduce on the front end.

  


  After creating all the hls segments correctly the php script fail to execute the command below.
The command getting error is the next one :
