• FFMPEG image + music = video

  24 septembre 2017, par Nikita Slastikhin

  Just trying todo video for youtube from image (1080p .png) + music (320Kb mp3).

      ffmpeg -loop 1 -i image.png -i music.mp3 -c:a copy -c:v libx264 -crf 0 -preset veryslow -shortest output.mp4
  

  But converting is to slowly.
  Any ideas, how it make optimize ?

  E:_TEST>ffmpeg -loop 1 -i image0.png -i music0.mp3 -c:a aac -c:v libx264 -crf 0 -preset veryfast -shortest video0.mp4

• Discord.py Music Bot problem with FFmpeg on heroku

  16 mai 2020, par Phantom_7331

  I'm coding my first music bot for discord and successfully tested it on the localhost. After that, I moved it on Heroku and installed FFmpeg buildpack for it. But for some reason, it doesn't work.
Here is proof that I installed FFmpeg buildpack on Heroku : Screen

  



  Here is my code (that works well on localhost) :

  



  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'
}

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')

@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))

    if 'entries' in data:
        data = data['entries'][0]

    filename = data['url'] if stream else ytdl.prepare_filename(data)
    return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)

@client.command()
async def join(ctx):
channel = ctx.message.author.voice.channel
if ctx.voice_client is not None:
    return await ctx.voice_client.move_to(channel)
await channel.connect()

@client.command()
async def play(ctx, *, URL):
    async with ctx.typing():
        player = await YTDLSource.from_url(url)
        ctx.voice_client.play(player, after=lambda e: print('Player error: %s' % e) if e else None)
    await ctx.send('Now playing: {}'.format(player.title))


  


• Manifest error pops up when trying to download certain videos for discord.py music bot

  30 novembre 2020, par bork

  I'm trying to make a discord music bot. I'm using youtube-dl to retrieve the info and ffmpeg to play the audio out. My bot has no problems downloading videos and everything is working fine. But when I tried downloading certain videos, this error popped up :

  


  [dash @ 0x7fe45a801200] Manifest too large: 65055
https://manifest.googlevideo.com/api/manifest/dash/expire/1606336104/ei/CGq-X4G6Htauz7sPrZuCsA8/ip/14.192.212.39/id/64a943d43b8f53eb/source/youtube/requiressl/yes/playback_host/r5---sn-h5mpn-30ae.googlevideo.com/mh/Go/mm/31%2C29/mn/sn-h5mpn-30ae%2Csn-30a7rn7l/ms/au%2Crdu/mv/m/mvi/5/pl/24/hfr/all/as/fmp4_audio_clear%2Cwebm_audio_clear%2Cwebm2_audio_clear%2Cfmp4_sd_hd_clear%2Cwebm2_sd_hd_clear/initcwndbps/533750/vprv/1/mt/1606314038/fvip/5/keepalive/yes/beids/23927369/itag/0/sparams/expire%2Cei%2Cip%2Cid%2Csource%2Crequiressl%2Chfr%2Cas%2Cvprv%2Citag/sig/AOq0QJ8wRQIhAOn6Br0QsuXc-3unfhYdzXVXcydzVWioIQlKvv2U4i3OAiB6ApoiqFoPvE3YKYGPbRiId_bHQYO8zsawGGPMidYGAA%3D%3D/lsparams/playback_host%2Cmh%2Cmm%2Cmn%2Cms%2Cmv%2Cmvi%2Cpl%2Cinitcwndbps/lsig/AG3C_xAwRQIhANmxfRNBI4wSJo6trsKkq8GinQ-ADMxgHRmelBwM-GEAAiAafey9YRrZz1h1S6PzV3u0S6IsZUKscGrrGP9Pofv2uQ%3D%3D: Invalid data found when processing input


  


  After trying to download other videos, which have no problem at all, I found out that the videos showing these errors have an extra step that downloads MPD manifest. I would try to download videos that are way larger and it would work, but it's just these certain videos, with the duration of about 7-10 minutes, that would have these errors. I'm really lost.

  


  This is my code for playing the videos in the voice channels :

  


  voice = get(client.voice_clients, guild = ctx.guild)
with YoutubeDL(ydl_opts) as ydl:
                info = ydl.extract_info(url[playlist], download = False)

URL = info['formats'][0]['url']
voice.play(FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))
