• ffmpeg codec for rtmp for Youtube fails for GetDisplayMedia

  19 janvier 2023, par Kubi

  I am trying to encode via a nodejs app and encode and output the incoming stream to RTMP and stream it on YouTube and these arguments below are working fine with getUserMedia API. However, I don't get any data when I try getDisplay media. Should I change any of these parameters ? I am a total beginner in ffmpeg.

  


  const youtubeArgs= [
    '-i', '-', '-v', 'error',
    '-c:v',
    'libx264',
    '-preset',
    'veryfast',
    '-tune',
    'zerolatency',
    '-g:v',
    '60',

    '-c:a',
    'aac',
    '-strict',
    '-2',
    '-ar',
    '44100',
    '-b:a',
    '64k',

    '-y',

    '-use_wallclock_as_timestamps',

• Error : Unable to extract uploader id - Youtube, Discord.py

  22 juillet 2024, par nikita goncharov

  I have a very powerful bot in discord (discord.py, PYTHON) and it can play music in voice channels. It gets the music from youtube (youtube_dl). It worked perfectly before but now it doesn't want to work with any video.
I tried updating youtube_dl but it still doesn't work
I searched everywhere but I still can't find a answer that might help me.

  


  This is the Error : Error: Unable to extract uploader id

  


  After and before the error log there is no more information.
Can anyone help ?

  


  I will leave some of the code that I use for my bot...
The youtube setup settings :

  


  youtube_dl.utils.bug_reports_message = lambda: ''


ytdl_format_options = {
    'format': 'bestaudio/best',
    'outtmpl': '%(extractor)s-%(id)s-%(title)s.%(ext)s',
    'restrictfilenames': True,
    'noplaylist': True,
    'nocheckcertificate': True,
    'ignoreerrors': False,
    'logtostderr': False,
    'quiet': True,
    'no_warnings': True,
    'default_search': 'auto',
    'source_address': '0.0.0.0',  # bind to ipv4 since ipv6 addresses cause issues sometimes
}

ffmpeg_options = {
    'options': '-vn',
}

ytdl = youtube_dl.YoutubeDL(ytdl_format_options)


class YTDLSource(discord.PCMVolumeTransformer):
    def __init__(self, source, *, data, volume=0.5):
        super().__init__(source, volume)

        self.data = data

        self.title = data.get('title')
        self.url = data.get('url')
        self.duration = data.get('duration')
        self.image = data.get("thumbnails")[0]["url"]
    @classmethod
    async def from_url(cls, url, *, loop=None, stream=False):
        loop = loop or asyncio.get_event_loop()
        data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url, download=not stream))
        #print(data)

        if 'entries' in data:
            # take first item from a playlist
            data = data['entries'][0]
        #print(data["thumbnails"][0]["url"])
        #print(data["duration"])
        filename = data['url'] if stream else ytdl.prepare_filename(data)
        return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)



  


  Approximately the command to run the audio (from my bot) :

  


  sessionChanel = message.author.voice.channel
await sessionChannel.connect()
url = matched.group(1)
player = await YTDLSource.from_url(url, loop=client.loop, stream=True)
sessionChannel.guild.voice_client.play(player, after=lambda e: print(
                                       f'Player error: {e}') if e else None)


  


• FFmpeg youtube stream get corrupted until restart

  19 février 2023, par unpwn

  I am streaming images from python to youtube using ffmpeg.
It's working fine with just one problem.
Sometimes the stream get somehow corrupted an the stream looks like this :

  


  Corrupted stream image

  


  Or you can see for yourself in the stream itself : https://www.youtube.com/watch?v=PG6NLtr0jjM (Scroll back to the beginning)

  


  Then I have to restart ffmpeg and its working fine. Sometimes an error occurs regarding the network and I have to automatically restart the stream. Then there is the possibility it is corrupted again.

  


  The parameters for ffmpeg are the following :

  


  cmd_out = ['ffmpeg',
       '-re',
       '-f', 'concat',
       '-i', os.path.join(BASE_DIR, 'music', 'music.txt').replace('\\', '/'),           
       '-r', '1',
       '-f', 'image2pipe',
       '-vcodec', 'png',
       '-r', '1',
       '-i', '-',
       '-c:v', 'libx264',
       '-c:a', 'copy',
       '-g', '4',
       '-f', 'flv',
       'rtmp://a.rtmp.youtube.com/live2/{}'.format(stream_key)]  


  


  I never had that problem testing it on windows. It just appears when I use my linux server.

  


  I am using ffmpeg version 3.2.18-0+deb9u1 and the generated images are fine, when I save them to a normal file.

  


  Does someone know how to fix it ? Or where the problem is comming from ?

  Solution : An old ffmpeg version was available while using docker. I solved the problem by using a static build from https://www.johnvansickle.com/ffmpeg/

  


  I used this to use it in docker :

  


  WORKDIR /app
ADD ./ffmpeg /app
RUN mv ffmpeg /usr/local/ffmpeg
RUN chmod +x /usr/local/ffmpeg


  


  Until now the error seems to be solved.
