  • Download a video from blob:https url from eventive

    26 août 2020, par jjcasmar

    I want to download a video from eventive but the tag contains a blob url (blob :https://watch.eventive.org/**************).

    


    I have been reading some answers to similar questions but they all assume that the video has a mp3u8 file extension, which in my case doesn't.

    


    I have also tried to directly download that url (removing the blob :) with curl, but I obtained a html code which I cant really understand, which contains a lot of references to javascript files.

    


    Any tip would be really helpful.

    


    Edit :

    


    I have been doing some more tests and I have been able to found a url to a manifest file which points apparently to the video data. I have tried to open that url using VLC and it loads some info about the video, and it even plays it, but the screen is completely black.

    


    I have also tried to download it using ffmpeg but it gives a bunch of errors.

    


    ffmpeg -i https://eventiveprod-usea.streaming.media.azure.net/02968382-069a-4f02-ab3b-67c0b5a8d5b7/5f427f2d65a569006ebd326c.ism/manifest\(format\=mpd-time-csf\)  output.mp4

  • ffmpeg : Can't convert file due to missing pixel format info ?

    20 mai 2020, par user13576035

    I'm new to ffmpeg and i've been having problems converting this kux file to mp4. I've converted other kux files in the same way before without issues but it seems that this one isn't working because the pixel format is missing from the metadata ?

    



    The error message I get is "Could not find codec parameters for stream 0 (Video : h264 (avc1 / 0x31637661), none, 1920x1080, 2991 kb/s) : unspecified pixel format
Consider increasing the value for the 'analyzeduration' and 'probesize' options"

    



    The pixel format of other files from the same site is yuv420p so i think that's what it should be.

    



    I tried ffmpeg -pix_fmt yuv420p -i input.kux output.mp4and some others but it doesnt work. Is there a way around this ?

    



    screen cap

    



    $ ffmpeg -i file.kux output.mp4

  • Errors while Audio decoding ?

    13 avril 2015, par Kuldeep More

    Hi all I am decoding audio streaming using FFMPEG API and writing into the .pcm file , but while decoding audio I am getting following errors .
    Also I am using Live555 to receive audio encoded streaming.

    Please tell me what is going wrong in the following code.

    I am calling following function for initializing purpose.

           AVCodec *acodec;
    
       AVCodecContext *ac=NULL;
    
       AVCodecParserContext *parser = NULL;
    
       AVFrame *picture;
    
       AVPacket avpkt;
    

    

    

    
  int initFFMpeg(RTSPClient* rtspClient)
    
  {  
    
      avcodec_register_all();
    
      av_init_packet(&avpkt);
    
      acodec = avcodec_find_decoder(AV_CODEC_ID_AAC);
    
      if (!acodec)
    
      {
    
        fprintf(stderr, "acodec not found audio codec\n");
    
        exit(1);
    
        return 0;
    
      }
    
      ac=avcodec_alloc_context3(acodec);
    
      picture = avcodec_alloc_frame();
    
      ac->skip_loop_filter=AVDISCARD_ALL;
    
      ac->strict_std_compliance = FF_COMPLIANCE_EXPERIMENTAL;
    
      ac->codec_type = AVMEDIA_TYPE_AUDIO;
    
      ac->channels = 2; 
    
      ac->sample_fmt = AV_SAMPLE_FMT_S16; // AV_SAMPLE_FMT_S16
    
      ac->sample_rate = 44100; // 44100
    
      ac->channel_layout = 3; // 3
    
      const AVRational timeBase = {1, ac->sample_rate};
    
      ac->time_base = timeBase;
    

    
      if (avcodec_open2(ac,acodec,NULL) < 0)
    
      {
    
        fprintf(stderr, "could not open codec\n");
    
        exit(1);
    
      }
    
  }

    And for decoding audio I am calling following function.

     void decodeaudioframe(unsigned char *fbuffer,int frameSize)
    
 {
    

    
  int len,out_size;
    
  unsigned char *buffer = new unsigned char[frameSize];
    
  memcpy(buffer, fbuffer, frameSize);
    
  uint8_t* in = buffer;
    
  int size = frameSize;
    

    
  while(size > 0)
    
  {
    
    avpkt.data =in;
    
    avpkt.size = size;
    

    
    len = avcodec_decode_audio4(ac, picture,&out_size,&avpkt);
    

    
    if (len < 0)
    
     {
    
         fprintf(stderr, "Error while decoding audio frame %d\n", aframe);
    
          break;
    
     }
    
     if(out_size)
    
     {
    
         fprintf(stderr, "Audio decoding audio success frame no= %d\n", aframe);
    
         printf("channels %d",picture->channels);
    
         printf("Sample rate=%d",picture->sample_rate);
    
         fwrite(picture,1,frameSize,faudio);
    

    

    
     }
    

    
     size -= len;
    
     in += len;
    
     ++aframe;
    
 }
    

    
  delete []buffer;
    
 }

    Following errors are coming when I run this code.
