• Ffmpeg x265 error : "Color Primaries must be", "ransfer Characteristics must be", "Matrix Coefficients must be" [closed]

  16 septembre 2022, par Mister Sir

  I'm trying to do the following conversion :

  


  ffmpeg -i video.mp4 -map 0 -c copy -c:v libx265 -crf 30 -vf "scale=-1:\'min(720,ih)\'" -c:a libopus -b:a 44k -map_metadata 0 -loglevel error -hide_banner video.mkv


  


  This works fine except for a specific video. I'm getting the following output :

  Can't find a single result when I google the first error text, ffmpeg "Color Primaries must be unknown"

  


  This is the verbose output :

  I'm not an expert at video encoding, so I don't really know what this all means. Probably something with the source file. How to get around this ? Thanks in advance ! If I need to upload the video, let me know how I can do that.

  


• How to Skip frames while decoding H264 stream ?

  16 septembre 2018, par TTGroup

  I’m using FFMPEG to decode H264 (or H265) RTSP Stream.

  My system have 2 software : Server and Client

  Server: Read frames from RTSP stream --> Forward frames to Client    
  
  Client: Receive frames from Server --> Decode --> Render

  I have implemented and it worked ok, but there is a case make my system work not good. That is when internet from Server - Client is slow, frames can not transfer real-time to Client.

  In present, I deal with this issue by Skip some frames (not send to Client) when the Queue is reached limit of count. The following is my summary code

  //At Server Software (include 2 threads A and B)
  
  //Thread A: Read AVPacket and forward to Client
  
  while(true)
  
  {
  
      AVPacket packet;
  
      av_init_packet(&packet);
  
      packet.size = 0;
  
      packet.data = NULL;
  
      int ret = AVERROR(EAGAIN);
  
      while (AVERROR(EAGAIN) == ret)
  
          ret = av_read_frame(pFormatCtx, &packet);
  
      if(packet.size > 0)
  
      {
  
          if(mySendQueue.count < 120) //limit 120 packet in queue
  
              mySendQueue.Enqueue(packet); ////Thread B will read from this queue, to send packets to Client via TCP socket
  
          else
  
              ;//SkipThisFrame ***: No send
  
      }
  
  }
  
  //Thread B: Send To Client via TCP Socket
  
  While(true)
  
  {
  
      AVPacket packet;
  
      if(mySendQueue.Dequeue(packet))
  
      {
  
          SendPacketToClient(packet);
  
      }
  
  }
  
  
  
  //At Server Software : Receive AVPacket from Server --> Decode --> Render
  
  While(true)
  
  {
  
      AVPacket packet;
  
      AVFrame frame;
  
      ReadPacketFromServer(packet);
  
      if (av_decode_asyn(pCodecCtx, &frame, &frameFinished, &packet) == RS_OK)
  
      {
  
          if (frameFinished)
  
          {
  
              RenderFrame(frame);
  
          }
  
      }           
  
  }
  
  UINT32 __clrcall av_decode_asyn(AVCodecContext *pCodecCtx, AVFrame *frame, int *frameFinished, AVPacket *packet)
  
  {
  
      int ret = -1;
  
      *frameFinished = 0;
  
      if (packet) 
  
      {
  
          ret = avcodec_send_packet(pCodecCtx, packet);
  
          // In particular, we don't expect AVERROR(EAGAIN), because we read all
  
          // decoded frames with avcodec_receive_frame() until done.
  
          if (ret < 0 && ret != AVERROR_EOF)
  
              return RS_NOT_OK;
  
      }
  
  
  
      ret = avcodec_receive_frame(pCodecCtx, frame);
  
      if (ret < 0 && ret != AVERROR(EAGAIN))
  
      {
  
          return RS_NOT_OK;
  
      }
  
      if (ret >= 0)
  
          *frameFinished = 1;
  
  
  
      return RS_OK;
  
  }

  My question is focus in line of code SkipThisFrame ***, this algorithm skip frame continuously, so it maybe make the decoder on Client occur unexpectedly error or Crash ?

  And when skip frame like that, make Client Render frames is not normally ?

  And someone call show me the proper algorithm to skip frames in my case ?

  Thank you very much !

• FFmpeg ignores some HTTP options when using the PUT method

  6 mars 2020, par mehdi.r

  I am using FFmpeg to create a CMAF stream and I upload it to an AWS resource (AWS MediaStore) using the PUT method of FFMpeg.
  I need to pass the Content-Type header when uploading manifests & segments.
  I have 3 type of files :

  application/x-mpegURL : m3u8 manifest

  application/dash+xml : mpd manifest

  video/mp4 : video segments

  Currently, all the types are set to Binary - octet-stream in the AWS resource (AWS MediaStore).
  As I will upload a huge number of files, I can’t use AWS Lambda functions to set the correct content type after a file as been uploaded.

  FFmpeg upload logs

  [https @ 0x555fe7a7d1c0] Opening 'https://XXXX.YYYY.amazonaws.com/chunk-stream0-00001.mp4' for writing

  My tries

  I tried static builds & master branch of FFMpeg.
  I tried different ways to pass the content type, without success :

  -mime_type 1 -headers "Content-type: video/mp4\r\n"

  -mime_type "video/mp4,application/dash+xml,application/x-mpegURL"

  -content_type application/dash+xml
