• Python FFMPEG Heroku|Remove audio from video with Byte to Byte. No web processes running Error

  15 mai 2021, par samoel

  I'm trying to get a .mp4 file from an address and remove the sound from it.I also want the data sent to FFMPEG to be bytes and return the result in byte

  


  i tried different command for my code like using -movflags frag_keyframe+empty_moov.
When I run this code in Heroku and receive the log...

  


  def from_bytes_to_byte(input_bytes):
    command = f"ffmpeg -f mp4 -i /dev/stdin -vcodec copy -an -f mp4 -movflags frag_keyframe+empty_moov -"
    convert_cmd = subprocess.Popen(
        shlex.split(command),
        stdin=subprocess.PIPE,
        stdout=subprocess.PIPE,
        shell=False
    )
    b = b''
    convert_cmd.stdin.write(input_bytes)
    convert_cmd.stdin.close()
    while True:
        output = convert_cmd.stdout.read()
        if len(output) > 0:
            b += output
        else:
            error_msg = convert_cmd.poll()
            if error_msg is not None:
                break
    print("----------FINISHED------------")
    return b


result=requests.get("https://file-examples-com.github.io/uploads/2017/04/file_example_MP4_480_1_5MG.mp4") #.MP4 File
byterecieved=from_bytes_to_byte(result.content)

• Process videos on Azure VM

  6 mars 2017, par sebastian.roibu

  I am building an application that will process uploaded video. Each uploaded video will be trimmed into multiple shorter parts and all the cuts will be concatenated to create a highlight of the original file. All the processing is done with ffmpeg.

  I am using Azure File Storage, to upload the videos and be able to access them via Samba layer.
  I also have an Azure VM where I mounted the shared folders.

  What is the best approach on the worker ?

  • Should I build a console app and run it as a windows server inside an azure VM ?

  • Is there another way of doing things ?

  I am looking for a way that can be scaled up in production.

  If there another way of doing everything I described above ?

• Converting MP3/MP4 to WAV in the Frontend Using ffmpegwasm with Next.js Results in Module Not Found Error

  31 mars 2024, par ryuma

  I'm attempting to use ffmpegwasm in a Next.js project to convert MP3 or MP4 files to WAV format directly in the frontend. However, I encounter a "Module not found" error during the process. I have made sure to use the latest version of Next.js. Below is the error message and the code snippet where the issue occurs. I'm seeking assistance to resolve this problem, as it has become quite troubling.
