• How to stop ffmpeg after it has finished python

  24 août 2017, par Joey B

  I have a function that finds an mp4 video in a temp folder, converts it to an mp3 in a seperate folder, called music, and then deletes the mp4 from the temp folder. It looks like such :

  import imageio
  
  imageio.plugins.ffmpeg.download()
  
  import moviepy.editor as mp
  
  
  
  def convert_mp4_to_mp3():
  
      video_file = os.listdir(os.getcwd() + '//temp')[0]
  
      audio_file = video_file.replace('mp4','mp3')
  
      clip = mp.VideoFileClip(os.getcwd() + '//temp//' + video_file)
  
      clip.audio.write_audiofile(os.getcwd() + '//music//' + audio_file)
  
      os.system("taskkill /f /im ffmpeg.win32.exe*32")
  
      os.remove(os.getcwd() + '//temp//' + video_file)

  The function successfully completes the conversion of mp4 to mp3 but when I try and delete the file, I get the following error :

  PermissionError: [WinError 32] The process cannot access the file because it 
  
  is being used by another process

  Upon trying to manually delete the file, I discovered it was because "ffmpeg.win32.exe" is still running with the file open. I could not manually delete it until I killed that process.

  I tried implementing the second to last line (os.system("taskkill /f /im ffmpeg.win32.exe*32") to kill the process but I still come up with the same error.

  So my question is, is there a simple way to kill ffmpeg once I know I am done with it or is there a workaround to somehow kill it via another process ? I am working in python3.6 on a windows 7 pc. Thanks in advance for the help !

• Discord.py, ffmpeg and pytube to play audio, but it keeps stopping early. Why ? [closed]

  15 septembre 2023, par LowEloTV

  I tried to program a discord,py bot to play audio, but the audio kept cutting out in the middle.

  


  @bot.command()
async def play(ctx, url: str):
    global ffmpeg_executable
    if discord.utils.get(ctx.guild.roles, name='music'):
        role = discord.utils.get(ctx.guild.roles, name='music')
        if role in ctx.author.roles:
            voice_client = ctx.voice_client


            if voice_client is None:
                channel = ctx.author.voice.channel
                voice_client = await channel.connect()
                print("Bot joined voice channel successfully.")


            try:
                # Fetch the audio stream URL using pytube
                yt = YouTube(url)
                audio_stream = yt.streams.filter(only_audio=True).first()


                # Play the audio stream using the VoiceProtocol
                if voice_client.is_playing():
                    voice_client.stop()
                voice_client.play(discord.FFmpegPCMAudio(audio_stream.url, executable=ffmpeg_executable))
            except Exception as e:
                await ctx.reply(f"An error occurred: {str(e)}")
        else:
            await ctx.reply('You don\'t have the permission for this command!')
    else:
        await ctx.reply('This Feature is not available on this guild, ask an Admin to add it!')

• Inserting clips into mp4 via ffmpeg

  15 septembre 2024, par lfgan

  I am looking to create mp4 files by combining multiple static mp4s and mp3s.
I have a script already to convert mp3 to mp4 and using the album art as a static background image, and inserting the intro.
What I am having problems with is that it cannot concatenate the videos reliably, or at all for that matter.

  


  This is the code that I currently have, it is ChatGPT, however I gave up as it seemed like it was just running in circles.

  


  setlocal

:: Set variables
set "mp3file=myfile.mp3"
set "coverart=extracted_cover.jpg"
set "outputfile=music.mp4"
set "introfile=intro.mp4"
set "outputendfile=Outro.mp4"
set "wowfile=Wow!.mp4"

:: Step 1: Extract cover art from MP3
ffmpeg -i "%mp3file%" -an -vcodec copy "%coverart%"
if %errorlevel% neq 0 (
    echo Error: Failed to extract cover art from MP3 file.
    exit /b 1
)

:: Step 2: Convert MP3 to MP4 using the extracted cover art
ffmpeg -loop 1 -i "%coverart%" -i "%mp3file%" -c:v libx264 -tune stillimage -c:a aac -b:a 192k -shortest "%outputfile%"
if %errorlevel% neq 0 (
    echo Error: Conversion from MP3 to MP4 failed.
    exit /b 1
)

:: Step 3: Randomly generate two positions for Wow!.mp4 insertions
:: Random positions will be between 10 and 50 seconds
set /a "pos1=%random% %% 40 + 10"
set /a "pos2=%random% %% 40 + 10"

:: Ensure pos1 and pos2 are different
if %pos1% EQU %pos2% (
    set /a "pos2=%pos1%+10"
)

:: Print positions for debugging
echo Random insertion positions:
echo Position 1: %pos1%
echo Position 2: %pos2%

:: Step 4: Split the music mp4 into parts at the random positions
:: Part 1: From the beginning to pos1
ffmpeg -i "%outputfile%" -c copy -ss 0 -to %pos1% -y "part1.mp4"
if not exist "part1.mp4" (
    echo Error: Failed to create part1.mp4
    exit /b 1
)

:: Part 2: From pos1 to pos2
ffmpeg -i "%outputfile%" -c copy -ss %pos1% -to %pos2% -y "part2.mp4"
if not exist "part2.mp4" (
    echo Error: Failed to create part2.mp4
    exit /b 1
)

:: Part 3: From pos2 to the end
ffmpeg -i "%outputfile%" -c copy -ss %pos2% -y "part3.mp4"
if not exist "part3.mp4" (
    echo Error: Failed to create part3.mp4
    exit /b 1
)

:: Step 5: Concatenate the files in the required order
(
    echo file 'intro.mp4'
    echo file 'part1.mp4'
    echo file 'Wow!.mp4'
    echo file 'part2.mp4'
    echo file 'Wow!.mp4'
    echo file 'part3.mp4'
    echo file 'Outro.mp4'
) > concat_list.txt

ffmpeg -f concat -safe 0 -i concat_list.txt -c copy final_output.mp4
if %errorlevel% neq 0 (
    echo Error: Failed to concatenate the video files.
    exit /b 1
)

:: Cleanup
del part1.mp4 part2.mp4 part3.mp4 concat_list.txt "%coverart%"

echo Done! The final video is saved as final_output.mp4


  


  exactly what it is supposed to do :

  


  

  1. Convert "myfile.mp3" to "music.mp4" with image (works)

  


  2. Add "intro.mp4" to the start of "music.mp4" and "Output.mp4" to the end (works)

  


  3. Split "music.mp4" into 3 parts, randomly, at a minimum 10s after intro.mp4 and 10s before Outro.mp4 (can for some reason only create part 1)

  


  4. Put all clips in order (unknown, probably works but part 2 and 3 wont generate so it cannot get to that step.)

  


  


  Edit :
I forgot to add the error message that I am getting. Here it is :

  


  [out#0 @ 000002e024a6ed00] -to value smaller than -ss; aborting.
Error opening output file part2.mp4.
