• Concat two .ts files gets audio out of sync

  14 octobre 2023, par Norbert Preining

  I am trying to concat two .ts files using ffmpeg. The files look like

  


  Part 0 :

  


  $ ffprobe -hide_banner part0.ts
Input #0, mpegts, from 'part0.ts':
  Duration: 00:00:25.02, start: 1.408000, bitrate: 76 kb/s
  Program 1 
    Metadata:
      service_name    : Service01
      service_provider: FFmpeg
  Stream #0:0[0x100]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(tv, unknown/bt709/iec61966-2-1, progressive), 1920x1080, 50 fps, 50 tbr, 90k tbn
  Stream #0:1[0x101]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 32000 Hz, stereo, fltp, 3 kb/s


  


  Part 1 :

  


  Input #0, mpegts, from 'part1.ts':
  Duration: 00:33:03.10, start: 1.408000, bitrate: 886 kb/s
  Program 1 
    Metadata:
      service_name    : Service01
      service_provider: FFmpeg
  Stream #0:0[0x100]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(progressive), 1920x1080 [SAR 1:1 DAR 16:9], 50 fps, 50 tbr, 90k tbn
  Stream #0:1[0x101](und): Audio: aac (LC) ([15][0][0][0] / 0x000F), 32000 Hz, stereo, fltp, 129 kb/s


  


  And concatenation is done using :

  


  ffmpeg -y -i "concat:part0.ts|part1.ts" -c copy -bsf:a aac_adtstoasc bla.mp4


  


  But the concatenated file always shows sync issues between audio and video. I have been using these to concatenate in the past without errors, but now it fails.

• AWS Lambda failed to resolve hostname on S3 signed url

  9 février 2024, par warly

  i'm trying to get ffmpeg working in AWS Lambda reading from and writing to S3. I crawled through dozens of aws documentations, stackoverflow questions and blog posts. All do it slightly different, but in the end none of them worked for me. So I hope to find help here :)
I sticked to the tutorial from InPlainEnglish : https://plainenglish.io/community/automated-video-processing-with-aws-lambda-and-ffmpeg-2834b7

  


  The ffprobe command does work, so ffmpeg is callable. But when calling ffmpeg with an S3 signed url i get the error Failed to resolve hostname my-bucket.s3.eu-central-1.amazonaws.com: System error

  


  export const handler = async (event) => {
    const s3 = new S3Client({});
    const bucket = event.Records[0].s3.bucket.name;
    const sourceKey = event.Records[0].s3.object.key;
    const sourceURL = await getSignedUrl(s3, new GetObjectCommand({
        Bucket: bucket,
        Key: sourceKey,
    }), {
        expiresIn: 900,
    });

    const tmpFilePath = 'tmp/video.mp4';
    const { convertOut } = await commander(`/opt/ffmpeg -i "${sourceURL}" -vf scale=1080:-2,format=yuv420p ${tmpFilePath}`);

    return {
        statusCode: 200,
        body: {
            result: JSON.stringify(convertOut),
        },
    };
};


  


  if anyone is able to point me in the right direction i would appreciate it :D
