• Node Media Server not stream when i try to pass the argument "transpose=1" to ffmpeg

  28 mai 2020, par joao.jlf4

  I'm using node-media-server to stream to instagram, and i need to rotate the original vídeo, to be portrait. I know that there is a flag on ffmpeg called transpose (there is rotate too), but when i pass it on node_relay_session.js on 24 line at the argv array, it returns me a "[Relay end]" on console, and it does'nt stream. When I remove the transpose flag from argv array it backs to stream normaly. Here is my config to nms :

  



  import NodeMediaServer from 'node-media-server';
import removeBarOfRtmpUrl from './utils/removeBarRtmpUrl';
import path from 'path';
import { remote } from 'electron';

export default function(data) {

const streams = data.map(stream => ({
endpoint: removeBarOfRtmpUrl(stream.endpoint),
key: stream.key,
}))

const config = {
rtmp: {
port: 1935,
chunk_size: 60000,
gop_cache: true,
ping: 30,
ping_timeout: 60
},
http: {
port: 8000,
allow_origin: '*'
},
relay: {
// C:\Users\Usuario\Desktop\multistream\node_modules.bin\ffmpeg.exe
ffmpeg: path.join(remote.app.getPath('appData'), '..', 'Local', 'Programs', 'multistream', 'app', 'ffmpeg', 'bin', 'ffmpeg.exe'),
tasks: streams.map(stream => ({
app: 'live',
mode: 'push',
edge: ${stream.endpoint}/${stream.key},

  }))
},
};

const nms = new NodeMediaServer(config);
return nms;
}

// {
// app: 'live',
// mode: 'push',
// edge: 'rtmp://a.rtmp.youtube.com/live2/keyyoutube',
// },```

• avcodec/dovi_rpudec : implement limited DM decompression

  avcodec/dovi_rpudec : implement limited DM decompression
  This implements the limited DM metadata compression scheme described in
  
  chapter 9 of the dolby vision bitstream specification.
  The spec is a bit unclear about how to handle the presence of static
  
  metadata inside compressed frames ; in that it doesn't explicitly forbid
  
  an encoder from repeating redundant metadata. In theory, we would need
  
  to detect this case and then strip the corresponding duplicate metadata
  
  from the existing set of static metadata. However, this is difficult to
  
  implement - esspecially for the case of metadata blocks which may be
  
  internally repeated (e.g. level 10).
  That said, the spec states outright that static metadata should be
  
  constant throughout the entire sequence, so a sane bitstream should not
  
  have any static metadata values changing from one frame to the next (at
  
  least up to a keyframe boundary), and therefore they should never be
  
  present in compressed frames. As a consequence, it makes sense to treat
  
  this as an error state regardless. (Ignoring them by default, or
  
  erroring if either AV_EF_EXPLODE or AV_EF_AGGRESSIVE are set)
  I was not able to find such samples in the wild (outside of artificially
  
  produced test cases for this exact scenario), so I don't think we need
  
  to worry about it until somebody produces one.
