• 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')


  


• Error in Splitting Educational Videos into Segments Using Python (ffmpeg issue) [closed]

  28 décembre 2024, par Yahia Mohamed Hanbal

  I created a Python project to split long educational videos into smaller segments, each focused on a single question. The program uses OCR to detect text on video frames, identifies the word "Question," extracts the number following it, and splits the video whenever the number increases.

  


  here is the video i am tring to split ((video))

  


  Here’s an example of the program’s output :

  


  Video loaded: 14071 frames at 60 FPS, duration: 234.52s  
Frame 480, Time 8.00s, Question: 6  
...  
Frame 12360, Time 206.00s, Question: 7  
Creating segment 1: 8.00s to 206.00s  
Error: module 'ffmpeg' has no attribute 'Error'


  


  I’ve shared the full code in a GitHub repository for reference : Automated Video Scene Cutting.

  


  What the Program Does

  


  

  • Input : A long educational video.

  


  • Processing :

    

    • Detects text in each frame using OCR.

    


    • Searches for the word "Question" followed by a number.

    


    • Monitors when the number increases to identify segment boundaries.

    


    


  


  • Output : Creates video segments corresponding to individual questions.

  


  


  The Problem

  


  The program detects the questions and timestamps correctly, but when it tries to create the segments, I encounter the following error :

  


  Error: module 'ffmpeg' has no attribute 'Error'


  


  What I’ve Tried

  


  

  • Verified the ffmpeg-python library is installed (pip show ffmpeg-python confirms the installation).

  


  • Ensured the ffmpeg binary is accessible from the command line.

  


  • Reviewed the library documentation to ensure the correct usage of ffmpeg.

  


  • Tested with different video files to rule out input-specific issues.

  


  


  Environment Details

  


  

  • OS : Windows 11

  


  • Python Version : 3.9.13

  


  • Key Libraries : ffmpeg-python

  


  


  If anyone has insights into resolving this issue or suggestions for alternative approaches to handle this use case, I’d greatly appreciate your help.

  


  Thank you !

  


• ffmpeg : two videos side-by-side with audio1 lang=ger & audio2 lang=eng

  19 janvier 2023, par miridigital

  I have two videos from two GoPro cameras. Both videos are rendered via ffmpeg side-by-side into a single video (left and right) and the audio is currently combined/mixed into two channels (stereo). I can hear both camera audio channels at the same time.

  


  Two channels stereo :

  


  ffmpeg -i video1.mp4 -i video2.mp4 -filter_complex "[0:v][1:v]hstack=inputs=2[v]; [0:a][1:a]amerge[a]" -map "[v]" -map "[a]" -ac 2 side-by-side.mp4


  


  audio from both videos mixed into a single file with 2 channels - mediainfo

  


  Now I want to switch between the two audio channels (cam1 or cam2) while I'm playing the side-by-side video.

  


  My first try : With four channels (without -ac 2 parameter) :

  


  ffmpeg -i video1.mp4 -i video2.mp4 -filter_complex "[0:v][1:v]hstack=inputs=2[v]; [0:a][1:a]amerge[a]" -map "[v]" -map "[a]" side-by-side.mp4


  


  audio from both videos mixed into a single file with 4 channels - mediainfo

  


  But the most video players can't easily select the channels 1+2 or 3+4 while playing.

  


  So I tried two languages :

  


  ffmpeg -i video1.mp4 -i video2.mp4 -filter_complex "[0:v][1:v]hstack=inputs=2[v]; [0:a][1:a]amerge[a]" -map "[v]" -map "[a]" -metadata:s:a:0 language=ger -metadata:s:a:1 language=eng side-by-side.mp4


  


  audio from both videos mixed into a single file with 4 channels with languages - mediainfo

  


  But that's wrong. I can only see german with 4 channels. How can I put channels 1+2 into german and channels 3+4 into english ? Afterwards I should be able to use the multi language feature from most video players to switch the audio between cameras.

  


  Thank you,
