• Conversion for WebM file format using FFMPEG

  23 mars 2012, par user974435

  I am using followng command to convert video to webm format

  ffmpeg -i video/ds2.mp4 -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b:a 345k -s 640x360 video/ds2.webm

  I am receiving following errors :

  1) incompatible sample format 's16' for codec 'libvorbis'

  2) strptime() unavailable on this system, cannot convert the data string

  Do you any idea why I cannot convert, tested conversion to FLV and it's working very well

  Console output

• muxing into MPEG-TS : wrong parameters for audio stream

  18 janvier 2017, par user1058600

  I am trying to mux video (H.264) and audio (PCM_S16LE, no compression) into an MPEG transport stream using ffmpeg. The video shows fine. The audio stream, however, does not play. The audio stream, shown by ffprobe is AAC, which is obviously not my intention. So I must be doing something wrong in adding the audio stream. Any idea how I can correct this ?

  This is my code for adding an audio stream :

  void add_audio_stream()
  
  {
  
  
  
      CodecID codec_id = CODEC_ID_PCM_S16LE;
  
  
  
      AVStream *p_ast = av_new_stream(fc, 1);
  
  
  
      if (!p_ast) {
  
          fprintf(stderr, "Could not alloc audio stream\n");
  
          exit(1);
  
      }
  
  
  
      ai = p_ast->index;
  
  
  
      AVCodecContext *pcc = p_ast->codec;
  
      avcodec_get_context_defaults2( pcc, AVMEDIA_TYPE_AUDIO );
  
  
  
      pcc->codec_type = AVMEDIA_TYPE_AUDIO;
  
      pcc->codec_id = codec_id;
  
      pcc->sample_fmt = AV_SAMPLE_FMT_S16;
  
      //pcc->bit_rate = 44100*16*2;
  
      pcc->bit_rate = 0;
  
      pcc->sample_rate = 44100;
  
      pcc->channels = 2;
  
      pcc->time_base = (AVRational){1, 44100};
  
  
  
  
  
      // some formats want stream headers to be separate
  
      if (fc->oformat->flags & AVFMT_GLOBALHEADER)
  
      {
  
          printf(" **** 1 ****\n");
  
          pcc->flags |= CODEC_FLAG_GLOBAL_HEADER;
  
      }
  
      else
  
          printf(" **** 2 ****\n");
  
  
  
  
  
      AVCodec *codec;
  
  
  
      /* find the audio encoder */
  
      codec = avcodec_find_encoder(pcc->codec_id);
  
      if (!codec) {
  
          fprintf(stderr, "codec not found\n");
  
          exit(1);
  
      }
  
  
  
  
  
      /* open it */
  
      if (avcodec_open(pcc, codec) < 0) 
  
      {
  
          fprintf(stderr, "could not open codec\n");
  
          exit(1);
  
      }
