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

  19 mars 2023, par Razurio

  SOLVED see end

  


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


@client.command()
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)
            await songs.put({"file": filename, "info": video_info(url)})
            # print("test 1")
    else:
        with yt_dlp.YoutubeDL({"format": "bestaudio", "outtmpl": "Queue_Download/%(title)s.%(ext)s"}) as ydl:

            # print("test 2")
        asyncio.create_task(queue(ctx))



async def queue(ctx):
    global songs
    global currently_playing
    currently_playing = True
    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 ctx.voice_client.play(discord.FFmpegPCMAudio(filename))

@client.command()
async def stop(ctx):
    global songs
    await ctx.voice_client.disconnect()
    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
took inspiration from this post

  


• Wowza : Live stream detected but does not play

  2 septembre 2016, par searcot jabali

  This is the command I use to being the stream on my hardware device
  ffmpeg -i /dev/video0 -f rtsp rtsp ://[user] :[password]@52.66.64.136:1935/test/myStream

  I can see that there is an input coming in from the Incoming Streams section of the Wowza Engine Manager.
  The IP, Stream name & Application name are correct.
  

  However when I try to play the stream using the Test Players, I dont see anything. Just a black screen.
  An error message at the bottom of Adobe HDS says Source stream or file could not be found or access was denied.

  

  When I try to use the RTSP wowza link on VLC I get an error stating that the "Input Cannot Be opened"

  Source security for RTSP has been set to open.

  When I stream through the GoCoder App there are no issues.
  This leads me to believe the server is functioning correctly.

  When I use the same command but change the output to write to file (ffmpeg -i /dev/video0 out.mp4) it works perfectly fine !!
  So even the base command is correct.

  Am I missing some arguments from the FFMPEG command ?
  Do I need to provide the username & password even though RTSP Source Security has been set to open ?

• FFMPEG libx264 mp4 file does not play in firefox Windows

  2 mai 2020, par Behel

  Some of my ffmpeg converted videos in mp4 format, using libx264 encoder, aren't playable with Firefox browser on Windows.

  



  Here is my ffmpeg command : 
ffmpeg -i file_tmp.mp4 -c:v libx264 -profile:v baseline -level 3.0 -crf 15 -preset slow -pix_fmt yuv420p -c:a aac -movflags faststart -strict -2 -vf scale=1024:576 file.mp4

  



  The video can be played with every browsers on Mac, and works well with Webkit based browers on Windows.

  



  The problem not occur with every video converted, only a few, like this one for instance : https://attentionphilippelepara.pet/testcard/m6-29_04_2020-mire.mp4

  



  Here is what I see when i try to play this media, on Firefow Windows then on Chrome Windows.

  



  

  



  I really don't see where is the problem. Can someone could help me ?
