• Streaming live video with avconv/ffmped on nginx rtmp server player error

  6 juin 2014, par user3715403

  Good morning,
  My current project involves playing live video (testing using a usb webcam for now). I compiled and installed nginx server with the rtmp module (obtained from https://github.com/arut/nginx-rtmp-module). The nginx configuration file is as :

  worker_processes  1;
  
  
  
  error_log  logs/error.log debug;
  
  
  
  events {
  
      worker_connections  1024;
  
  }
  
  
  
  rtmp {
  
      server {
  
          listen 1935;
  
  
  
          application myapp {
  
              live on;
  
  
  
              #record keyframes;
  
              #record_path /tmp;
  
              #record_max_size 128K;
  
              #record_interval 30s;
  
              #record_suffix .this.is.flv;
  
  
  
              #on_publish http://localhost:8080/publish;
  
              #on_play http://localhost:8080/play;
  
              #on_record_done http://localhost:8080/record_done;
  
          }
  
      }
  
  }
  
  
  
  http {
  
      server {
  
          listen      8080;
  
  
  
          location /stat {
  
              rtmp_stat all;
  
              rtmp_stat_stylesheet stat.xsl;
  
          }
  
  
  
          location /stat.xsl {
  
              root /path/to/nginx-rtmp-module/;
  
          }
  
  
  
          location /control {
  
              rtmp_control all;
  
          }
  
  
  
          #location /publish {
  
          #    return 201;
  
          #}
  
  
  
          #location /play {
  
          #    return 202;
  
          #}
  
  
  
          #location /record_done {
  
          #    return 203;
  
          #}
  
  
  
          location /rtmp-publisher {
  
              root /path/to/nginx-rtmp-module/test;
  
          }
  
  
  
          location / {
  
              root /path/to/nginx-rtmp-module/test/www;
  
          }
  
      }
  
  }

  The command line to start streaming is as :

  avconv -s vga -f video4linux2 -i /dev/video0 -vcodec libx264 -an -f flv -b 800k -r 30 rtmp://localhost/myapp/live

  While streaming, the following stats are displayed :

• 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=''

• Problems with frame rate on video conversion using ffmpeg with libx264 [migrated]

  29 mai 2013, par Lars Schroeter

  I have problems with transcoding some videos. I ran the most simple ffmpeg command and it takes very long time and the output file is about 10 times bigger. If I provide the frame rate parameter -r it works well (small file, fast transcoding). What is the problem and how can I solve it ? I don't want to set a fixed frame rate because I guess it's better to leave it the same as source, isn't it ?.

  Maybe the problem is something else, because I found many examples in web where the -r option isn't used. Also transcoding to a different format or with a different source works well without -r option (I tried with ffmpeg 0.7.15 and also 1.2.1). The videos are provided by the users of my website and automatically converted to be suitable for the web. So I need the most general command for automatic conversion.

  In the following ffmpeg output you will find this two suspicious messages :

  • Frame rate very high for a muxer not effciciently supporting it. Please consider specifiying a lower framerate, a different muxer or -vsync 2
  • MB rate (36000000) > level limit (983040)

  The ffmpeg command and output (without -r option) :
