• How to make an exact (byte for byte) clone of mkv file using ffmpeg ?

  9 juillet 2019, par fat_flying_pigs

  My end goal is to swap two audio channels in an mkv file while changing nothing else. Swapping the audio channels in ffmpeg is quite easy and not part of this question. It was my thought process that being able to make a 1:1 copy of the file would be a good first step.

  Using a very simple example : ffmpeg -i sample.mkv -c copy out.mkv will result in an output file smaller than the original.

  With a drastically more complicated example, such as : ffmpeg -i sample.mkv -y -map 0:0 -map 0:1 -map 0:2 -map 0:3 -map 0:4 -vcodec copy -acodec copy -scodec copy out.mkv, it seems that :

  1. chapters are missing/dropped
  2. metadata is missing
  3. global metadata is added (possibly related to a lack of -map_metadata

• fs.readFile is failed to read thumbnail generated file using ffmpeg in nodejs

  5 avril 2019, par Schüler

  I am using ffmpeg to extract the screenshot from the video it is working as expected but that file is unable to read/buffer using fs.read, later I will have to upload the image to the s3 bucket, So who can I make the file readable ?

  var thumPath =  path.join(global.__base, 'Temp/');
  
      ffmpeg(req.file.path).screenshots({
  
              count: 1,
  
              filename: req.file.filename + 'thumbnail-at-%s-seconds.png',
  
              folder: thumPath,
  
              size: '320x240'
  
          });
  
  
  
         fs.readFile(thumPath + req.file.filename + 'thumbnail-at-%s-seconds.png', function(err, thumb) {
  
            console.log(thumb) 
  
  //s3 bucket feature will come
  
         })

• OSError : [Errno 9] Bad file descriptor discord bot

  11 août 2020, par user10509686

  I am working on a discord bot using the discord.py API. I am trying to make the bot join a voice channel and play an mp3 file that is in the same directory. It joins the voice channel but prints the error in the title before playing anything. I was wondering what was causing this error. Relevant code below :

  


  @client.command()
async def playClip(ctx):
    global voice
    channel=ctx.message.author.voice.channel
    voice= get(client.voice_clients, guild=ctx.guild)

    if voice and voice.is_connected():
        await voice.move_to(channel)
    else:
        voice= await channel.connect()

    voice.play(discord.FFmpegPCMAudio("BravoSix.mp3"))
    print("test")
    await voice.disconnect()
