  I am compiling the ffmpeg library i am facing some issues while compiling this.

  I follow the steps of compilation form here.But i am failed to compile.
  The issues are as below.

• FFMPEG Concatenating videos with same 25fps results in output file with 3.554fps

  5 juin 2024, par Kendra Broom

  I created an AWS Lambda function in node.js 18 that is using a static, ver 7 build of FFmpeg located in a lambda layer. Unfortunately it's just the ffmpeg build and doesn't include ffprobe.

  


  I have an mp4 audio file in one S3 bucket and a wav audio file in a second S3 bucket. I'm uploading the output file to a third S3 bucket.

  


  Specs on the files (please let me know if any more info is needed)

  


  Audio :
wav, 13kbps, aac (LC), 6:28 duration

  


  Video :
mp4, 1280x720 resolution, 25 frame rate, h264 codec, 3:27 duration

  


  Goal :
Create blank video to fill in the duration gaps so the full audio is covered before and after the mp4 video (using timestamps and duration). Strip the mp4 audio and use the wav audio only. Output should be an mp4 video with the wav audio playing over it and blank video for 27 seconds (based on timestamp) until mp4 video plays for 3:27, and then blank video to cover the rest of the audio until 6:28.

  


  Actual Result :
An mp4 file with 3.554 frame rate and 10:06 duration.

        await uploadFileToS3(outputBucket, outputKey, outputPath);
        console.log('File upload complete.');

        return { statusCode: 200, body: JSON.stringify('Video and audio have been merged successfully.') };
    } catch (error) {
        console.error('Error in Lambda function:', error);
        return { statusCode: 500, body: JSON.stringify('Failed to process video and audio.') };
    }
}


  


  Attempts :
I've tried re-encoding the concatenated file but the lambda function times out. I hoped that by creating blank video with a 25fps and all the other specs from the original mp4, I wouldn't have to re-encode the concatenated file. Obviously something is wrong, though. In the commented out code you can see I tried specifying 25 or not, and also tried -vsync and no -vsync. I'm new to FFmpeg so all tips are appreciated !
