• Extract thumbnail from video in amazon s3 and store it in amazon s3 [closed]

  24 juin 2021, par Kanav Raina

  I want to extract thumbnail from video and store it on s3.

  


  import ffmpeg

url="https://link_to_s3_video.mp4"

(
    ffmpeg
    .input(url, ss='00:00:03')  
    .output("frame.png", pix_fmt='rgb24', frames='1')  
    .overwrite_output()
    .run()
)


  


  I am able to extract image but now how should I pass this image to file_upload function and store it on s3

  


  def file_upload(file, filename):
    link = f"https://{PUBLIC_BUCKET_NAME}.s3.us-east-2.amazonaws.com/images/{filename}"
    try:
        s3.Object(PUBLIC_BUCKET_NAME, f"images/{filename}").load()
    except ClientError as e:
        if e.response['Error']['Code'] == "404":
            try:
                s3_client.upload_fileobj(
                    file,
                    PUBLIC_BUCKET_NAME,
                    f"images/{filename}",
                    ExtraArgs={'ACL': 'public-read'}
                )

                return 200, link
            except ClientError as e:
                logging.error(e)
                return 500, ""
        else:
            return 500, ""
    else:
        return 409, link


  


  Thanks

  


• discord music bot downloads all videos on a webpage instead of just one

  11 janvier 2021, par IdotEXE

  When I try and run this code with any given youtube URL, it will usually say : "Downloading video 1 of 25", and then obviously times out. Downloading the videos as an mp3 file does work, but obviously, I don't need 25 mp3 files whenever I'm only trying to play one video as audio. Anyone got any ideas as to why this happens ?

  


  @bot.command()
async def play(ctx, url : str):
    song_there = os.path.isfile("song.mp3")
    try:
        if not os.path.exists("song.mp3"):
            os.remove("song.mp3")
    except PermissionError:
        await ctx.send("Wait for the current music to end / use stop command")
        return

    voiceChannel = ctx.message.author.voice.channel

    await voiceChannel.connect()
    voice = discord.utils.get(bot.voice_clients, guild=ctx.guild)


    ydl_opts = {
        'format' : 'bestaudio/best',
        'postprocessors': [{
            'key' : 'FFmpegExtractAudio',
            'preferredcodec' : 'mp3',
            'preferredquality' : '192',
        }]
    }

    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        ydl.download([url])
    for file in os.listdir('./'):
        if file.endswith(".mp3"):
            os.rename(file, "song.mp3")
    voice.play(discord.FFmpegAudio("song.mp3"))

@bot.command()
async def leave(ctx):
    voice = discord.utils.get(bot.voice_clients, guild= ctx.guild)
    if voice.is_connected():
        await voice.disconnect()
    else:
        await ctx.send("The bot is not connected to a voice channel")

@bot.command()
async def pause(ctx):
    voice = discord.utils.get(bot.voice_clients, guild= ctx.guild)
    if voice.is_playing():
        voice.pause()
    else:
        await ctx.send("Currently no audio is playing")

@bot.command()
async def resume(ctx):
    voice = discord.utils.get(bot.voice_clients, guild= ctx.guild)
    if voice.is_paused():
        voice.resume()
    else:
        await ctx.send("The audio is not currently paused")

@bot.command()
async def stop(ctx):
    voice = discord.utils.get(bot.voice_clients, guild=ctx.guild)
    voice.stop()
