  avdevice/decklink_dec : Convert decklink input module to use codecpar
  There are still a couple of deprecated calls that I’m not sure what to do with.
  
  They are both related to some logic around AVCodecContext.coded_frame.
  
  I couldn’t find anywhere that really documented what that was, or where it was intended to move to.
  
  I left the warnings on.

• avcodec/opus : Move stuff shared by decoder and parser to a new file

  3 octobre 2022, par Andreas Rheinhardt

  avcodec/opus : Move stuff shared by decoder and parser to a new file
  opus.h (which is used by all the Opus code) currently includes
  
  several structures only used by the parser and the decoder ;
  
  several elements of OpusContext are even only used by the decoder.
  This commit therefore moves the part of OpusContext that is shared
  
  between these two components (and used by ff_opus_parse_extradata())
  
  out into a new structure and moves all the other accompanying
  
  structures and functions to a new header, opus_parse.h ; the
  
  functions itself are also moved to a new file, opus_parse.c.
  
  (This also allows to remove several spurious dependencies
  
  of the Opus parser and encoder.)

• How to manage hls in Nginx RTMP module

  27 mars, par syrkandonut

  I would like to manage the hls broadcast on request, like stop/start or some other way in Nginx RMTP module.
My rtmp server needs to support many cameras, however, when it does ffmpeg exec for 200-300 rtmp streams, this is very difficult for the processor, so I would like to execute the ffmpeg command in parallel only on request, how could this be done ?

  


  Rtmp Server

  


  rtmp {
    server {
        listen 1935;
        chunk_size 8192;

        application live {
            live on;
            record off;
            drop_idle_publisher 10s;
            allow publish all;

            on_publish rtmp-router:8082/on_publish;

              exec ffmpeg -i rtmp://localhost:1935/live/$name
              -f lavfi -i anullsrc -c:v copy -c:a aac -shortest -f flv rtmp://localhost:1935/hls/$name_main;
        }


        application hls {
            live on;
            hls on;
            hls_fragment_naming system;
            hls_fragment 2;
            hls_playlist_length 4;
            hls_path /opt/data/hls;
            hls_nested on;

            hls_variant _main BANDWIDTH=878000,RESOLUTION=640x360;
        }
    }
}


  


  I would like to solve this through nginx or python itself, since the server running with threads is written in FastAPI.
