P.S. the original video uploaded onto the instagram has sound.

    


    there is a code bellow

    


    import moviepy.editor as mp


INPUT_FILE_PATH = rf'input\video.mp4'
OUTPUT_FILE_PATH = rf'output\video.mp4'

video = mp.VideoFileClip(INPUT_FILE_PATH)


logo = (mp.ImageClip("logo.png")
        .set_duration(video.duration)
        .resize(width=width / 3)
        .margin(right=width // 20, top=5 * height // 8, opacity=0)  # (optional) logo-border padding
        .set_pos(("right", "top")))

final = mp.CompositeVideoClip([video, logo])


final.write_videofile(OUTPUT_FILE_PATH, fps=30, codec="libx264", audio_fps=22050, audio_bitrate="31k")

  • Stream voice from Android's micro to RTMP server using FFMPEG

    5 avril 2020, par user2258282

    I'm trying to mix audios from Android's microphone and a mp3 file in storage and stream to a RTMP server using FFMPEG

    



    Now, I could stream a single mp3 file to RTMP server by the below command

    



    ffmpeg -i  -acodec libmp3lame -ab 128k -ac 2 -ar 44100 -f flv rtmp://


    



    And, I could stream audio from Mac's microphone to RTMP server by the below command

    



    ffmpeg -f avfoundation -i ":0" -f flv rtmp://


    



    But now I haven't found command to mix audios from Android's microphone and a mp3 file in storage and stream to a RTMP server using FFMPEG. Can you help me ?

    



    Thank you so much.

    


  • FileNotFoundError on aws Lambda when concatenating videos with ffmpeg

    2 juillet 2021, par Shibu Menon

    Goal :

    



      

    • Concat 2 videos (both are in an s3 bucket) via aws Lambda using ffmpeg

      • 


    • Upload the resultant output.mp4 to another S3 bucket

      • 


    • Python 3+

      • 


    



    I've already created a layer containing a static ffmpeg

    



    The Error :

    



    {
  "errorMessage": "[Errno 2] No such file or directory: '/tmp/output.mp4'",
  "errorType": "FileNotFoundError",
  "stackTrace": [
    [
      "/var/task/lambda_function.py",
      19,
      "lambda_handler",
      "s3.Object(bucketLowRes, mp4OutputFileName).put(Body=open(new_file_key, 'rb'))"
    ]
  ]
}


    



    My Lambda function :

    



    import json
import os
import subprocess
import boto3

s3 = boto3.resource('s3')
bucketLowRes = s3.Bucket("bucket-conc-lowres")

def lambda_handler(event, context):
    # TODO implement

    mp4OutputFileName = 'output.mp4'

    new_file_key = os.path.abspath(os.path.join(os.sep, 'tmp', mp4OutputFileName))
    subprocess.call( ['/opt/ffmpeg', '-i', 'concat:s3://bucket-word-clips/00th76kqwfs915hbixycb77y9v3riwsj30.mp4|s3://bucket-word-clips/00uoakp6jyafbu13ycvl6w2i9tj42eux30.mp4', new_file_key ] )

    s3.Object(bucketLowRes, mp4OutputFileName).put(Body=open(new_file_key, 'rb'))

    return {
        'statusCode': 200,
        'body': json.dumps('Hello from Lambda!')
    }


    



    Question :

    



      

    • FileNotFoundError : Where is the output mp4 file of my ffmpeg concat being saved ??

      • 


    • And if it is being saved to /tmp/output.mp4 , then why the FileNotFoundError ??

      • 


    



    thanks
