• GNU Radio + leandvb demodulation of DVB-S signals

  25 juillet 2016, par ShatteredPheonix

  I am new to signal processing and RF, however I am trying to receive Ham TV signals from the ISS in gnu radio and then demodulate them using leandvb so that I can playback the video through a standard player like VLC.

  So please excuse my incorrect terminology where used :

  I have the following GNU Radio Setup :
  

  A few things about the file I am using is that it was recorded at 1msps with a symbol rate of 1 which was done via USRP.

  After playing the flow graph this seem to be the result :
  

  The above image, to me looks like a fairly clean signal - in addition to this I can’t seem to clear it up anymore.

  However, when I put it through a DVB-S demodulater called leandvb it can’t seem to get any TS packets out.

  instead it reports :

  rawiq            : 1647M/549M   2048 writable  ,   2048 unread ( 0 
  
  2048 2048 )
  
  autonotched      : 2197M/549M   3072 writable !,   1024 unread ( 0 0 1024 0 )
  
  PSK symbols      : 955M/477M   4057 writable  ,   4870 unread ( 373 4870 )
  
  freq             :   0M/  0M      2 writable  ,      0 unread ( 0 )
  
  bytes            :   0M/  0M   9792 writable  ,      0 unread ( 0 )
  
  RS-enc packets   :   0M/  0M      4 writable  ,      0 unread ( 0 )
  
  rand TS packets  :   0M/  0M      4 writable  ,      0 unread ( 0 )
  
  TS packets       :   0M/  0M      4 writable  ,      0 unread ( 0 0 )
  
  SS               :   0M/  0M      1 writable  ,      1 unread ( 1 )
  
  packet counter   :   0M/  0M    400 writable  ,      0 unread ( 0 )
  
  Total buffer memory: 422 KiB

  it seems to have problems reading some symbols and raw data but I don’t know why and I have tried almost everything I can think of to get it work.

  and when I try to play the resulting ts file through mplayer / ffmpeg / ffplay / vlc I get various errors :

  • File does not contain Stream
  • Invalid data while preprocessing
  • Cannot prefill buffer

  Can anyone help me and tell me where I am going wrong ? As I am completely clueless and have been trying to solve this problem for about 2 weeks now ?

• Discord bot cannot play youtube video for more than 60sec

  18 octobre 2020, par Antoine Weber

  A few weeks back I started a discord bot as a side project for fun.
Since yesterday i've been trying to allow my bot to search youtube videos and play them in voice channels (mostly for songs).

  


  The bot correctly searches youtube with the query and finds the youtube video, starts playing it, but for some reason, after 60 sec (no matter of the video, always the same time), the bot suddenly provides no more audio, and then gets stuck somewhere (not a single error message, but the bots just stops responding).

  


  Here are the code snippets :

  


  # first two words are activation keywords for the bot, then its the youtube query
query = ' '.join(message.message.content.split()[2:])
youtube = build("youtube", "v3", developerKey=yt_token)
search_response = youtube.search().list(q=query, part="id,snippet", maxResults=5).execute()
video_id = search_response['items'][0]['id']['videoId']
video_url = "https://www.youtube.com/watch?v=" + video_id

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
     ydl.download([video_url])
await play_audio(message, 'song.mp3')


  


  (I delete the song.mp3 after playing)

  


  my ydl options are

  


  ydl_opts = {
    "postprocessors":[{
        "key": "FFmpegExtractAudio", # download audio only
        "preferredcodec": "mp3", # other acceptable types "wav" etc.
        "preferredquality": "192" # 192kbps audio
    }],
    "format": "bestaudio/best",
    "outtmpl": "song.mp3"
}


  


  and also my play_audio function is

  


  async def play_audio(message, audio_name):
        channel = message.message.author.voice.channel
        vc = await channel.connect()
        time.sleep(0.5)
        vc.play(discord.FFmpegPCMAudio(audio_name))
        while vc.is_playing():
            time.sleep(1)
        vc.stop()
        await vc.disconnect()


  


  I know the time.sleep() call is blocking but I don't really core for now.

  


  Any one had this issue ? For short videos (less than 60sec), everything works fine. Maybe an ffmpeg option ?
