• FFmpeg to create a custom time stamp with suffix (mins, hrs, days) and user defined time between frames

  14 juillet 2021, par Block Island

  I am looking to use FFmpeg (or something similar) to overlay a time stamp on videos.

  


  I want it to have similar functionality to the timestamper plugin from ImageJ (I can't use ImageJ for this as it does not allow for large video files).

  


  I'd like to be able to enter a starting time, a time between frames and a suffix. My video is made up of an image taken every 10 minutes for 20 days and I want to overlay the day as the video is playing. So for this, I'd like frames 1-144 (144 images per day) have 0 days in the corner of the video, frames 145-289 to have 1 days in the corner, and so on.

  


• 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')


  


• avformat/daudenc : force 2000 sample packet size with a bsf

  3 mars 2024, par Marton Balint

  avformat/daudenc : force 2000 sample packet size with a bsf
  The samples I found all have 2000 sample packets, and by forcing the packet
  
  size with a bsf we could automagically make muxing work for packets containing
  
  more than 3640 samples.
