• Mixing video streams with a fade transition effect myself

  28 mai 2013, par AsTeR

  I would like to make a a software setup that would let the user switch between two webcam feeds (or more but let's consider two). I would like a fade in/out effect while switching. My main problem is that I don't know how to start.

  There seems to be some ffmpeg tool that could do the job (like libavfilter) but I don't get how I could setup it.

  What should I consider to use if I want to access frame image to make the transition myself ? Is there some simpler way ?

  I know that this question looks really poorly written, but I'm as lost as I look.

• voice_client.play doesn't continue loop (Discord) (Solved)

  SOLVED see end

  


  songs = asyncio.Queue(maxsize=0)
currently_playing = False

async def play(ctx, url):
    global songs
    global currently_playing
    if currently_playing:
        with yt_dlp.YoutubeDL({"format": "bestaudio", "outtmpl": "Queue_Download/%(title)s.%(ext)s"}) as ydl:
            info = ydl.extract_info(url, download=True)
            filename = ydl.prepare_filename(info)

    while True:
        if songs.empty():
            currently_playing = False
            await ctx.reply("Queue is now empty")
            await ctx.voice_client.disconnect()  # disconnect from voice channel when queue is empty
            break
        else:    
            song = await songs.get()
            filename = song["file"]
            voice_channel = ctx.author.voice.channel
            if not ctx.voice_client:  # check if bot is not already connected to a voice channel
                await voice_channel.connect()

            await ctx.reply('playing')

    await empty_queue(songs)
    await ctx.reply('Stopped')

async def empty_queue(songs):
    while not songs.empty():
        songs.get_nowait()


  


  I have problems with the "await ctx.voice_client.play(discord.FFmpegPCMAudio(filename))" which doesn't continue after finishing.

  


  I know you can use a after= parameter in voice_client.play() but I didn't manage to get it to work to recursivly call queue()

  


  async def play_next(ctx):
global songs
global currently_playing
if songs.empty():
    currently_playing = False
    await ctx.reply("Queue is now empty")
    await ctx.voice_client.disconnect()  # disconnect from voice channel when queue is empty
else:    
    song = await songs.get()
    filename = song["file"]
    voice_channel = ctx.author.voice.channel
    if not ctx.voice_client:  # check if bot is not already connected to a voice channel
        await voice_channel.connect()

    def after(error):
        if error:
            print(f'Error in after callback: {error}')
        asyncio.create_task(play_next(ctx))

    await ctx.reply('playing')
    ctx.voice_client.play(discord.FFmpegPCMAudio(filename), after=after)


  


  I tried using the after parameter like like but I just get an error in line 116, in after asyncio.create_task(play_next(ctx)) "no running event loop" ... "Calling the after function failed"

  


  EDIT

  


  async def play_next(ctx):
global loop
global songs
global currently_playing
global tasks
loop = asyncio.get_event_loop()
if songs.empty():
    currently_playing = False
    await ctx.reply("Queue is now empty")
    await ctx.voice_client.disconnect()  # disconnect from voice channel when queue is empty
else:
    
    song = await songs.get()
    filename = song["file"]
    voice_channel = ctx.author.voice.channel
    if not ctx.voice_client:  # check if bot is not already connected to a voice channel
        await voice_channel.connect()
    def after(error):
        if error:
            print("er")
        loop.create_task(queue(ctx))

    await ctx.reply('playing')
    ctx.voice_client.play(discord.FFmpegPCMAudio(filename), after=after)


  


  using loop = asyncio.get_event_loop() and loop.create_task(queue(ctx)) made it finally work
