• lavf/dashenc : pass standards compliance value to the internal context

  27 avril 2018, par Jan Ekström

  lavf/dashenc : pass standards compliance value to the internal context
  Enables one to test possibly nonstandard formats such as Opus or
  
  FLAC in ISOBMFF, among other things.
  This becomes much more useful if output segment format becomes an
  
  option, or if the WebM segment feature gets removed.

• Invalid data found when processing input when using Streaming Discord Bot (python)

  4 mai 2022, par DimKewl

  After refactoring and working on all possible solutions I could find on google
I always get the following error :

  


  Invalid data found when processing input

  


  My code snippet :

  


   FFMPEG_OPTIONS = {
    "before_options": "-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5",
    "options": "-vn -sn -dn"
}
@commands.command()
async def radio(self,ctx,url):
    await self.joinLogic(ctx)
    await self.playStreamOpus(ctx,url)

async def joinLogic(self, ctx):
    if ctx.author.voice is None:
        await ctx.send("Please join a voice channel!")
    else:
        voice_channel = ctx.author.voice.channel
        if ctx.voice_client is None:
            await voice_channel.connect()

async def playStreamOpus(self, ctx, url):
    source = await discord.FFmpegOpusAudio.from_probe(url, **self.FFMPEG_OPTIONS)
    ctx.voice_client.play(source)


  


  What have I already tried :

  


  

  • Re-install all dependencies on pip.

  


  • A variety of streaming links that were working in the past for the same code.

  


  • Tried the PCM instead of Opus.

  


  • Different streaming URLs.

  


  • More options in FFMPEG_Options to explicit that I need only audio.

  


  • Made sure that my bot is joined in my channel and can reach other places in my code.

  


  


  Streaming (sample) links I tried (worked before) :

  


  

  • https://streema.com/radios/StereoAnime

  


  • http://www.e-radio.gr/Radio-Polis-994-Larisa-i54/live

  


  • http://live24.gr/radio/generic.jsp?sid=169

  


  


  Full FFmpeg options from Debugger console :
['ffmpeg', '-reconnect', '1', '-reconnect_streamed', '1', '-reconnect_delay_max', '5', '-i', 'http://www.e-radio.gr/Radio-Polis-994-Larisa-i54/live', '-map_metadata', '-1', '-f', 'opus', '-c:a', 'libopus', '-ar', '48000', '-ac', '2', '-b:a', 'Nonek', '-loglevel', 'warning', '-vn', 'pipe:1']

  


  Youtube links work just fine in a similar method in the class.

  


  async def playYouTube(self,ctx,url): 
   await self.joinLogic(ctx) 
   YDL_OPTIONS = { "format": "bestaudio" }
   voiceClient = ctx.voice_client 

   with youtube_dl.YoutubeDL(YDL_OPTIONS) as youTube: 
       info = youTube.extract_info(url, download=False) 
       formattedUrl = info['formats'][0]['url'] 
       source = await discord.FFmpegOpusAudio.from_probe(formattedUrl, **self.FFMPEG_OPTIONS)
       voiceClient.play(source) 


  


  So most likely the problem lies with the URLs, which still boggles me cause they were working before ?

  


  Any insights will be highly appreciated !

  


• Executing FFmpeg recording using in-line SDP

  3 décembre 2020, par Sarvesh Patil

  I'm trying to record audio on a webrtc server in NodeJS using FFmpeg.

  


  I am able to record the audio if I explicitly create an input.sdp file and use it with the "-i" flag of FFmpeg.

  


  My question is : How to create a string in the code to dynamically change port numbers for recording different streams at the same time ?

  


  I tried doing this :

  


      const sdpInfo = `data:application/sdp;charset=UTF-8,v=0\no=- 0 0 IN IP4 ${ipAddr}\ns=-\nc=IN IP4 ${ipAddr}\nt=0 0\nm=audio ${port} RTP/AVPF 111\na=rtcp:${port+1}\na=rtpmap:111 opus/48000/2\na=fmtp:111 minptime=10;useinbandfec=1`


  


  However, if I give it as input with "-i" flag, I get the following error :

  


  


  data:application/sdp ;charset=UTF-8,v=0 : Invalid data found when processing input

  


  


  Can someone please help ?
