• Small discord bot with a set of working music commands, about 6 days ago the play function completely stopped functioning (more below)

  24 février 2021, par TheColoradoKid

  It is a small discord python bot for my server with various features, which had included music commands until they stopped out of the blue without showing any error for the problem.
It uses FFMpeg, and youtubeDl along with pytube to gather the song and store it locally to play it, I have pip updated all of these and they are definitely on the current versions as I have made sure of this online.
Any help or insight anyone could provide would be greatly appreciated. I'm sorry if the code is convoluted in the way it's written I'm still pretty new to coding and this is one of my first proper larger projects.

  


  If you need any information I'm happy to give what I can to help.

  


  Here is the code for the play command :

  


  @client.command()
async def play(ctx, *args):
    global queu
    #global autom
    if not args:
        voice = get(client.voice_clients, guild=ctx.guild)
        if not voice.is_playing():
            server = ctx.message.guild
            voice_channel = server.voice_client
            if queu:
                async with ctx.typing():
                    player = await YTDLSource.from_url(queu[0], loop=client.loop)
                    voice_channel.play(player, after=lambda e: print('Player error: %s' % e) if e else None)

                await ctx.send('**Now playing:** {}'.format(player.title))
                del(queu[0])
                # while autom == True:
                #     try:
                #         a = client.get_command('auto')
                #         await ctx.invoke(a)
                #     except:
                #         print('')
            elif not queu:
                await ctx.send("You can't play if there isn't anything in the queue\nIf auto mode was on it has now been disabled, to use it gain please add to the queue and run ``;auto on``")
                autom = False
    if args:
        global gueu
        search_keywords = ""
        print(args)
        for word in args:
            search_keywords += word
            search_keywords += '+'
        link = "https://www.youtube.com/results?search_query="
        link += search_keywords
        #print(link)
        html = urllib.request.urlopen(link)
        video_ids = re.findall(r"watch\?v=(\S{11})", html.read().decode())
        url = ("https://www.youtube.com/watch?v=" + video_ids[0])
        #print(url)
        queu.append(url)
        #print(queu)
        await ctx.send("``{}`` added to queue!\n If the song doesn't start please either let the current song end and run ``;play``/``;next`` again or run ``;next`` to play now".format(url))
        try:
            p = client.get_command('play')
            await ctx.invoke(p)
        except:
            print('failed')


  


• Compressed mp4 video is taking too long time to play in Android(exo player)

  4 mai 2018, par User

  Video(mp4) is recorded from android camera and sent to backend, here I am using ffmpeg wrapper to compress the video[44mb video to 5.76mb]. compression is working well, But when I send the video for play in android(exo player), is taking too long time to start.

  below is my code to compress :

   FFmpegBuilder builder = new FFmpegBuilder()
  
                     .setInput("D:/dummyVideos/myvideo.mp4")     // Filename, or a FFmpegProbeResult
  
                     .overrideOutputFiles(true) // Override the output if it exists
  
                     .addOutput("D:/dummyVideos/myvideo_ffmpeg.mp4")   // Filename for the destination
  
                     .setFormat("mp4")       // Format is inferred from filename, or can be set
  
                     .disableSubtitle()       // No subtiles
  
                     .setAudioChannels(1)         // Mono audio
  
                     .setAudioCodec("aac")       // using the aac codec
  
                     .setAudioSampleRate(48_000) // at 48KHz
  
                     .setAudioBitRate(32768)     // at 32 kbit/s
  
                     .setVideoCodec("libx264")     // Video using x264
  
                     .setVideoFrameRate(24, 1)     // at 24 frames per second 
  
                     .setVideoResolution(1280, 720) // at 640x480 resolution
  
                     .setVideoBitRate(762800)
  
                     .setStrict(FFmpegBuilder.Strict.EXPERIMENTAL) // Allow FFmpeg to use experimental specs
  
                     .done();

  Can anyone tell me why video is taking too long time to play in exo player ? Is anything wrong in the compression ?

• Video created via ffmpeg will not play on iPhone 10 or Huawei Android using Chrome

  17 février 2020, par MHatton

  I have created a video from a image and adding an MP3 file. It plays fine on my Moto G Android phone and on my desktop, but a collegue has said it will not play on his iPhone 10 or Huawei Android phone running Chrome.

  Does the following ffmpeg need an extra command adding to make the created MP4 more compatible across devices ?

  ffmpeg -loop 1 -i 6f4aa5dfefc4dd32186f41315ad9d1e2-0.png -i "download.mp3" -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest aw-slide0.mp4
