• How can I use libav to encode video to dvd compliant mpeg2

  18 juillet 2014, par Dave Camp

  Im new to using FFMpeg and I’d like to do the equivalent of using the command line option -f dvd but in my app, by using the libav api. In the source of FFMpeg the option sets up some parameters as

   opt_video_codec(o, "c:v", "mpeg2video");
  
   opt_audio_codec(o, "c:a", "ac3");
  
   parse_option(o, "f", "dvd", options);
  
  
  
   parse_option(o, "s", norm == PAL ? "720x576" : "720x480", options);
  
   parse_option(o, "r", frame_rates[norm], options);
  
   parse_option(o, "pix_fmt", "yuv420p", options);
  
   av_dict_set(&o->g->codec_opts, "g", norm == PAL ? "15" : "18", AV_DICT_DONT_OVERWRITE);
  
  
  
   av_dict_set(&o->g->codec_opts, "b:v", "6000000", AV_DICT_DONT_OVERWRITE);
  
   av_dict_set(&o->g->codec_opts, "maxrate", "9000000", AV_DICT_DONT_OVERWRITE);
  
   av_dict_set(&o->g->codec_opts, "minrate", "0", AV_DICT_DONT_OVERWRITE); // 1500000;
  
   av_dict_set(&o->g->codec_opts, "bufsize", "1835008", AV_DICT_DONT_OVERWRITE); // 224*1024*8;
  
  
  
   av_dict_set(&o->g->format_opts, "packetsize", "2048", AV_DICT_DONT_OVERWRITE);  // from www.mpucoder.com: DVD sectors contain 2048 bytes of data, this is also the size of one pack.
  
   av_dict_set(&o->g->format_opts, "muxrate", "10080000", AV_DICT_DONT_OVERWRITE); // from mplex project: data_rate = 1260000. mux_rate = data_rate * 8
  
  
  
   av_dict_set(&o->g->codec_opts, "b:a", "448000", AV_DICT_DONT_OVERWRITE);
  
   parse_option(o, "ar", "48000", options);

  How do these relate to the libav api ?

  The incoming video frames are at the correct resolution for pal of 720x576 in yuv420p format. Some of my params...

  pCodec = avcodec_find_encoder(AV_CODEC_ID_MPEG2VIDEO);
  
  
  
  pContext->bitrate = 48000000;
  
  pContext->width = 720;
  
  pContext->height = 576;
  
  
  
  AVRational fps = {1,25};
  
  pContext->time_base = fps;
  
  
  
  pContext->gop_size = 15;
  
  pContext->max_b_frmaes = 2;
  
  pContext->pix_fmt = AV_PIX_FMT_YUV420P;
  
  
  
  av_set_dict(&pDict,"packet_size","2048",0); // This seems to be ignored?
  
  
  
  avcodec_open2(pContext,pCodec,&pDict);

  The AVDictionary... What is the dictionary ? How does it relate the encoding process ? Is it simply a user dictionary for passing a collection of settings around your code ?

  Ultimately I’d like to be able to transcode incoming video frames that are already in the correct size and format for pal dvd and output a dvd compliant mpeg2 video ( data packets of 2048 bytes ). I understand the mpeg2 video format but I’m confused with ffmpeg params.

  Thanks !

• My discord music bot works locally, but not on a server [closed]

  8 décembre 2022, par Asmondya

  I have an issue with my discord music bot that I made with discord.js v14.

  


  When I run it locally, it works fine and plays music as it should. But when I put in on a server (here I use Vultr), it doesn't work.

  


  I am not sure but it might come from FFmpeg. I am kinda desperate and cant really figure where the issue is from. I think it is FFmpeg because it is what converts the music.

  


  What happens :

  


  Me: !play a music
Bot: Now playing a music
*and right after, without playing the music*
Bot: Music finished


  


  What should normally happen is that same thing but the "music finished" should be sent when the queue is finished.

  


  The thing is that the bot works perfectly locally, but does this when it is hosted on a server. Also I don't have any error messages or else. It just doesn't play the music like if the music was 0 seconds length.

  


  I tried making sure everything is installed on the server, same as making sure ffmpeg was installed globally and I have the good version of it. Here is the answer I have to the "ffmpeg -version" command :enter image description here.

  


  Does anyone know what could be the issue or what could cause it ? I can show some code if needed, even tho it works perfectly fine locally.

  


  Here's my code :

  It does come from my ffpmeg, I need to install one of these packages instead of the npm installation : https://github.com/BtbN/FFmpeg-Builds/releases

  


  How do I install it on a server (Vultr) ?
