• FFMPEG concat video throws No Such Filter error

  5 janvier 2021, par Rohan Shah

  I am trying to concat three videos using FFMPEG,

  


  This is my command that I am executing using Java Runtime

  


      String command = "ffmpeg -i url_to_video -i url_to_video -i url_to_video -filter_complex [0:v] [0:a] [1:v] [1:a] [2:v] [2:a] concat=n=3:v=1:a=1 [v] [a] -map [v] -map [a] /home/rohan/output.mp4";

    Process process = Runtime.getRuntime().exec(command.split(" "));


  


  This is throwing me No Such Filter error, whereas if I try to run this via Terminal it works perfectly fine. I tried tweaking the cmd by removing or adding quotes, but any variant of this command that runs on terminal throws error in Java Runtime. While it runs perfectly on the Terminal.

  


  I have tried with Absolute paths and Amazon S3 URLs, while both of them work just fine in terminal, The S3 variant of command throws No Such Filter error and the Absolute path command throws a No Such File Or Directory error during Runtime.

  


  Here is the stack trace of the error

  


  Here is the standard error of the command (if any):

• ffmpeg single output container with 4 audio channel to AWS IVS

  28 juillet 2021, par Yusufu

  Trying to send 1 video and 4 different audios to AWS IVS in single container. Which container or muxer should I use ?
FLV doesn't support multi audio, matroska doesn't support rtmp I guess link.
3GP and mp4 containers doesn't give me error but neither video showing on IVS

  


  For simple try I am using this command.

  


  ffmpeg -re -stream_loop -1 -i sample.mkv -r 30 -c:v libx264 -pix_fmt yuv420p -profile:v main -preset veryfast -x264opts "nal-hrd=cbr:no-scenecut" -minrate 3000 -maxrate 3000 -g 
60 -c:a aac -ac 2 -ar 44100 -vb 400k -maxrate 400k -minrate 400k -bufsize 800k -movflags frag_keyframe+empty_moov -f mp4 rtmps:someurls


  


  the above command doesn't include multi audio output so just trying to send except the flv format

  


• AWS lambda mp4 thumbnail generator using ffmpeg - incorrect format generated

  10 avril 2021, par sam bhandu

  I am trying to create a thumbnail generator for every mp4 file uploaded to the s3 bucket. I have been following this post published by AWS. The code works fine for the transcoding video file. I changed the code to generate a thumbnail. The code does generate a file but it is an invalid image type.

  


  import json
import os
import subprocess
import shlex
import boto3
import uuid

S3_DESTINATION_BUCKET = "example-bucket"
SIGNED_URL_TIMEOUT = 60

def lambda_handler(event, context):

    # s3_source_bucket = event['Records'][0]['s3']['bucket']['name']
    # s3_source_key = event['Records'][0]['s3']['object']['key']
    # s3_source_basename = os.path.splitext(os.path.basename(s3_source_key))[0]
    # s3_destination_filename = s3_source_basename + "_cfr.ts"
    
    hex_c = uuid.uuid4()
    s3_destination_filename = '/{}/{}.{}'.format('tmp',hex_c, 'jpg')
    s3_client = boto3.client('s3')
    s3_media_url = 'https://s3-us-west-2.amazonaws.com/example-bucket/videos/presentations/testing.mp4'
    ffmpeg_cmd = "/opt/bin/ffmpeg -i \"" + s3_media_url + "\" -ss 00:00:02 -vframes 1  \"" + s3_destination_filename + "\""
    # ffmpeg_cmd = "/opt/bin/ffmpeg -i \"" + s3_source_signed_url + "\" -f mpegts -c:v copy -af aresample=async=1:first_pts=0 -"
    
    command1 = shlex.split(ffmpeg_cmd)
    p1 = subprocess.run(command1, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
   
    resp = s3_client.put_object(Body=s3_destination_filename, Bucket=S3_DESTINATION_BUCKET, Key='{}{}'.format(hex_c, '.jpg'))
    return {
        'statusCode': 200,
        'body': json.dumps('Processing complete successfully')
    }


  


  Output is as :

  


  {
  "statusCode": 200,
  "body": "\"Processing complete successfully\""
}
