• FFMpeg frame drop when merging a image sequence and overlaying during video creation process

  29 juillet 2018, par Killer

  I have reviewed both the answer as mentioned in Similar Issue But still, I am having some frame drops.

  Here is what I was doing :
  Question 1
  Question 2

  Currently, I am showing a few images (one after another each with
  duration ’x’) on a sample background along with a music playing in the
  background.

  This is the command I am using to get the desired functionality :

  ffmpeg 
  
  -hide_banner 
  
  -y 
  
  -loop 1 
  
  -r 1 
  
  -i /data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Images/IMG_WED_MOJO_WEDDING_FRAME.png 
  
  -r 1/4 
  
  -i /data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Images/IMG_WED_MOJO_SELECTED_IMAGE_%d.png 
  
  -filter_complex overlay=(W-w)/2:(H-h)/2,drawtext=text=WedMojo:fontcolor=white:fontfile=/data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Files/FONT_WED_MOJO_WEDDING.ttf:fontsize=30:x=w-tw-20:y=h-th-20 
  
  -c:v libx264 
  
  -profile:v high 
  
  -crf 17 -pix_fmt yuv420p 
  
  -preset ultrafast 
  
  -t 16 -strict experimental 
  
  -r 24 
  
  /data/user/0/mojo.wed.com.wedmojo/cache/wedding_video/Videos/VID_WED_MOJO_WEDDING_OUTPUT.mp4

  note : -r 1/4 for each image to be shown for 4 sec.

  I have checked the format of the images. All are the same. Also on changing preset and other values, the problem seems to be same. Log states drop=0, however, there are gaps as the overlay image is removed in between.

  Video sample with the duration set to 4 i.e each image to be set for 4 seconds.

  -> -> Video Output with 4 sec duration for each image

  However, there are no frame drops when the duration set to 1 or 2.

  -> -> Video Output with 2 sec duration for each image, ignore zoompan

  Log details :

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

  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 :

  Your input can’t be opened :

  Any suggestions about what would cause the errors displayed by VLC/avplay ?

• 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
