• 2023-04-18 18:25:05 INFO discord.player ffmpeg process ##### successfully terminated with return code of 0

  19 avril 2023, par I_am_thing

  I am making a discord music bot with discord.py and ctx, it uses Spotify

  


  I am using FFmpeg for my music feature. This is my !play code

  


  client_id = ''
client_secret = ''
client_credentials_manager = SpotifyClientCredentials(client_id=client_id, client_secret=client_secret)
sp = spotipy.Spotify(client_credentials_manager=client_credentials_manager)

bot.volume = 0.5 # initial volume of the bot (can be changed)

@bot.command()
async def play(ctx, *, track_query):
    # check if the query is a valid Spotify link
    if 'open.spotify.com/track/' in track_query:
        track_id = track_query.split('/')[-1] # extract the track ID from the link
    else:
        # search for tracks with the given name
        track_results = sp.search(q=track_query, type='track', limit=1)
        if len(track_results['tracks']['items']) == 0:
            await ctx.send(f'Sorry, I could not find any track with the name "{track_query}".')
            return
        track_id = track_results['tracks']['items'][0]['id'] # get the track ID for the first search result
    track_info = sp.track(track_id) # get the track information for the given ID
    track_name = track_info['name']
    track_artist = track_info['artists'][0]['name']
    track_duration = time.strftime('%M:%S', time.gmtime(track_info['duration_ms']//1000))
    track_preview_url = track_info['preview_url'] # get the preview URL for the track
    if track_preview_url is None:
        await ctx.send(f'Sorry, the track "{track_name}" by {track_artist} cannot be played.')
        return
    voice_channel = ctx.author.voice.channel
    if voice_channel is None:
        await ctx.send('Please join a voice channel first.')
        return
    voice_client = await voice_channel.connect()
    audio_source = discord.FFmpegPCMAudio(track_preview_url, options="-b:a 128k -bufsize 512k")
    voice_client.play(audio_source, after=lambda e: print('Player error: %s' % e) if e else None)
    voice_client.source = discord.PCMVolumeTransformer(voice_client.source)
    voice_client.source.volume = bot.volume

    # format the embed message
    embed = discord.Embed(title=track_name, description=track_artist, color=0xff8c00)
    embed.add_field(name='Duration', value=track_duration, inline=True)
    embed.set_thumbnail(url=track_info['album']['images'][0]['url'])
    embed.set_footer(text='This music is from https://www.spotify.com/')
    await ctx.send(embed=embed)

    while voice_client.is_playing():
        await asyncio.sleep(1)
    await voice_client.disconnect()


  


  I joined the unofficial ffmpeg discord server no one could find a fix I searched for ages and I couldn't fix it

  


• Assistance required with filter graph construction(fast motion between times)

  6 janvier 2023, par D-MAN

  I am trying to re-create the following video, using ffmpeg.
https://youtu.be/eVQ9ysp0Pj0. "please check 0.19 minute for examples"
I have the following line of code which has most of the elements, except the part where is applies fast motion for 1s at certain outputs([vfr1][vfr2][vfr3])/times. currently it is only setpts=0.5*PTS[vboom] for the entire length of the video.

  


  exe = "-i " + file + " -i " + frame + " -i " + framestart + " -i " + frameEnd + " -i " + audioOverlay + " -filter_complex \"[0:v]pad="+mVideoWidth+":"+mVideoHeight+":576:0[vpad]; [vpad][1]overlay[vframed]; [vframed]split=3[vfr1][vfr2][vfr3]; [vfr1]reverse[vrev]; [vfr2][vrev][vfr3]concat=n=3,setpts=0.5*PTS[vboom]; [vboom][2]overlay=enable='lte(t,2)'[vpreout]; [vpreout][3]overlay=enable='gte(t,"+msec+"*3*0.5-2)' \" -map 4:a -b:v 8000k -shortest -preset ultrafast -crf 23 " + file2.getAbsolutePath();

  


  i have tried the following code snippets in various sections of the filter graph, with no luck !

  


  //[0:v]trim=0:2,setpts=PTS-STARTPTS[v1] ;[0:v]trim=2:5,setpts=2*(PTS-STARTPTS)[v2] ;[0:v]trim=5,setpts=PTS-STARTPTS[v3] ;
//[0:v]trim=0:10,setpts=PTS-STARTPTS[vfr1] ;[0:v]trim=10:30,setpts=PTS-STARTPTS[vfr2] ;[0:v]trim=start=30,setpts=PTS-STARTPTS[vfr3] ;
//[0:v]trim=2:3,setpts=0.75*(PTS-STARTPTS) ; [0:v]trim=4:5,setpts=0.75*(PTS-STARTPTS) ; [0:v]trim=7:8,setpts=0.75*(PTS-STARTPTS) ;
//[0:v]select='between(t,1,4)+between(t,4,6)',setpts=0.87*PTS ;
