• Ffmpeg throws File Not Found Error in Python but works fine in terminal

  6 avril 2022, par Abhishek Bhadola

  I am trying to concatenate audio and video in my pc through ffmpeg, wrote a code for that

  


  input_video=str("E:\\Downloaded\\temp\\2 Types of knapsack.mp4")
input_audio=str("E:\\Downloaded\\temp\\2 Types of knapsack.mp3")

print(input_video)

subprocess.run([
            "./ffmpeg",
            "-i",
            f"{input_video}",
            "-i",
            f"{input_audio}",
            "-c",
            "copy",
            "E:\\Downloaded\\2 Types of knapsack.mp4"
        ])


  


  now when i try to run the code in python it crashes and throws me an error that the file,path is wrong,but the same ffmpeg command written in terminal works fine

  


  ffmpeg -i "E:\Downloaded\2 Types of knapsack.mp4\2 Types of knapsack.mp4" -i "E:\Downloaded\2 Types of knapsack.mp4\2 Types of knapsack.mp3" -c "E:\Downloaded\2 Types of knapsack.mp4"


  


  any fixes.?

  


• ffmpeg is making my audio and video frozen and I don't know why

  17 avril 2024, par Sdpro

  I'm using bunjs runtime to execute ffmpeg as terminal code but I don't know if my code is typescript code is wrong or ffmpeg is wrong
and I'm using json file to get the clips correctly

  


      let videos = 0;
    let stepsTrim = "";
    let concatInputs = "";

    for (let i = 0; i < 40; i++) {
        if (unwantedWords[i].keepORdelete === true) {
            stepsTrim += `[0:v]trim=0:${
                unwantedWords[i].start
            },setpts=PTS[v${i}];[0:a]atrim=0:${
                unwantedWords[i].start
            },asetpts=PTS-STARTPTS[a${i}];[0:v]trim=${unwantedWords[i].start}:${
                unwantedWords[i].end
            },setpts=PTS[v${unwantedWords.length + i + 1}];[0:a]atrim=${
                unwantedWords[i].start
            }:${unwantedWords[i].end},asetpts=PTS-STARTPTS[a${
                unwantedWords.length + i + 1
            }];`;

            concatInputs += `[v${i}][a${i}][v${unwantedWords.length + i + 1}][a${
                unwantedWords.length + i + 1
            }]`;
            videos += 2; 
        }
    }

    stepsTrim = stepsTrim.slice(0, -1);

    await $`ffmpeg -hide_banner -i ${videoRequirements.output} -filter_complex "${stepsTrim},${concatInputs} concat=n=${videos}:v=1:a=1[outv][outa]" -map "[outv]" -map "[outa]" -c:v libopenh264 -preset slow -c:a mp3 -vsync 1 -y ${removedUnwantedWords}/fastAf.mp4`;


  


  at the end after everything was done :

  


  warning

I can't figure out why ffmpeg is sometimes making the audio + video work and sometimes not

  I have tried commands from many types of ffmpeg commands changing the code and I can't seem to get the audio and video right

  


• Pydub FFMPEG issue [closed]

  14 janvier, par Nikolai van den Hoven

  I am attempting to use FFMPEG with Pydub to create a program that chops .mp3 files into different words, each contained in their own .mp3 file, but when I run the script I am getting the following error :

  


  PS C:\Users\nik> & C:/Users/nik/AppData/Local/Microsoft/WindowsApps/python3.12.exe "d:/Python/Word Splitter.py"

  warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)


  


  This is the code I am using.

AudioSegment.ffmpeg = r"D:\Python\ffmpeg\bin\ffmpeg.exe"

    # Ensure output folder exists
    os.makedirs(output_folder, exist_ok=True)

    # Load MP3 file
    print("Loading audio file...")
    audio = AudioSegment.from_mp3(mp3_file)

    # Split audio into chunks using silence detection
    print("Splitting audio into chunks...")
    chunks = split_on_silence(
        audio,

    recognizer = sr.Recognizer()

        with sr.AudioFile(temp_file) as source:
            audio_data = recognizer.record(source)
            try:
                text = recognizer.recognize_google(audio_data)
                words = text.split()

                word_start = 0
                for j, word in enumerate(words):

                    word_audio = chunk[word_start:word_start + word_duration]
                    word_file = os.path.join(output_folder, f"word_{i}_{j}.mp3")
                    word_audio.export(word_file, format="mp3")
                    word_start += word_duration

            except sr.UnknownValueError:
                print(f"Could not understand chunk {i + 1}.")
            except sr.RequestError as e:

  I have added the Base FFMPEG folder and the bin folder within it to Windows PATH
My PATH variable on Windows 11,
But it does not show up in the variable when I typed PATH into cmd
