   # make

       #include "version.h"

  I have searched this a lot but couldn’t manage to do it, Amazon support officer asked me to use CENTOS AMI instead of Linux AMI but I have everything hosted there, so I will appreciate if someone can help me with this.

  Thank you,

• how to download portion of video which was uploaded into AWS s3 bucket, though Nodejs SDKs

  22 février 2024, par rama rangeswara reddy

  I have uploaded a 1GB .mp4 file to an AWS S3 bucket. Using the AWS-SDK provided by the npm package, I am able to download the entire video. However, I have a specific requirement to generate a thumbnail at the 6-second mark of the video. Currently, I download the entire 1GB video to my local machine and then generate the thumbnail at the desired duration.

  


  To optimize server resources and reduce disk load, I plan to download only the first 10 seconds of the video, which should be approximately 10MB or less in size. By doing so, I can significantly reduce download time and server load while still fulfilling my requirement of generating the thumbnail at the 6-second mark. Therefore, instead of downloading the entire 1GB video, I aim to download only the 10MB segment corresponding to the first 10 seconds of the video.

  


  I am using nodejs, expressJS, as backed Technologies.

  


  `

  


  `async function downloadS3FileToLocalDirAndReturnPath(videoKey) {
    return new Promise(async (resolve, reject) => {
        try {
            AWS.config.update({
                accessKeyId: config.AWS.KEYS.accessKeyId,
                secretAccessKey: config.AWS.KEYS.secretAccessKey,
                region: config.AWS.KEYS.region,
                httpOptions: config.AWS.KEYS.httpOptions
            });
            const s3 = new AWS.S3();

            // Specify the local file path where you want to save the downloaded video
            const localFilePath = `${os.tmpdir()}/${Date.now()}_sre.mp4`;

            // Configure the parameters for the S3 getObject operation
            const params = {
                Bucket: config.AWS.S3_BUCKET,
                Key: videoKey
            };

            const result = await s3.getObject(params).promise();
            const fileContent = result.Body;
            fs.writeFileSync(localFilePath, fileContent);
            resolve(localFilePath);
        } catch (error) {
            reject(error);
        }
    });
}`


  


  this code was working fine to download the whole video , but i need to download only first 10 seconds duration

  


  S3 : How to do a partial read / seek without downloading the complete file ?

  


  I tried this ,before posting this question with above post, video was downloading , it was not playing , by throwing this error , the file contains no playable streams

  


  async function generateThumbnails(videoKey) {

const s3 = new AWS.S3();

const params = {
    Bucket: KEYS.bucket,
    Key: videoKey, // Specify the key of the video file in S3
    Range: `bytes=0-${1024 * 800}`, // Specify the range of bytes you want to retrieve
};

const file = fs.createWriteStream(`/tmp/${Date.now()}_rama.mp4`);

const s3Stream = s3.getObject(params).createReadStream();

s3Stream.pipe(file);

s3Stream.on("error", (error) => {
    console.log("Error Occured while File downloading!! ");
});

s3Stream.on("finish", () => {
    console.log("File downloaded Successfully ");
});

• ffmpeg upload transcoded video direct to gcs bucket using node child_process.spawn

  27 mai 2021, par Dev

  I'm trying to upload transcoded video directly to GCS, but when I used pipe with FFmpeg for GCS upload it exits with code 1.

  


  const fp = `file_path/${video_name}`;
const bc = admin.storage().bucket("test");
const fu = bc.file(fp);
const ws = fu.createWriteStream({
    metadata: {
        contentType: 'video/mp4',
        metadata: {
            name: video_name,
        },
    },
});
const transcode = new Promise((resolve, reject) => {
    const ffmpeg = spawn('ffmpeg', ['-i', `${url}`, '-codec:v', 'libx264', '-profile:v', 'main', '-vf', `scale=-2:${quality}`, '-threads', '0', '-b:a', '128k', 'pipe:1']);
    ffmpeg.stderr.on('data', (data) => {
    });
    ffmpeg.stdout.pipe(ws);
    ffmpeg.on('close', async (code) => {
        console.log(code)
        resolve();
    });
});
return transcode;
