Menus personnalisés
14 novembre 2010, parMediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.

Le plugin : Gestion de la mutualisation
2 mars 2010, parLe plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.

On installe les fichiers de SPIP sur le serveur.
On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.

React Native (Android) : Download mp3 file
21 février 2024, par Batuhan FındıkI get the youtube video link from the ui. I download the video from this link and convert it to mp3. I download it to my phone as mp3. The song opens on WhatsApp on the phone. but it doesn't open on the mp3 player. The song is not broken because it opens on WhatsApp too. Why do you think the mp3 player doesn't open ? Could it be from the file information ? I tried to enter some file information but it still won't open. For example, there is from information in songs played on an mp3 player. There is no from information in my song file. I tried to add it but it wasn't added.


.net 8 api return :


[HttpPost("ConvertVideoToMp3")]
public async Task<iactionresult> ConvertVideoToMp3(Mp3 data)
{
 try
 {
 string videoId = GetYoutubeVideoId(data.VideoUrl);

 var streamInfoSet = await _youtubeClient.Videos.Streams.GetManifestAsync(videoId);
 var videoStreamInfo = streamInfoSet.GetAudioOnlyStreams().GetWithHighestBitrate();

 if (videoStreamInfo != null)
 {
 var videoStream = await _youtubeClient.Videos.Streams.GetAsync(videoStreamInfo);
 var memoryStream = new MemoryStream();

 await videoStream.CopyToAsync(memoryStream);
 memoryStream.Seek(0, SeekOrigin.Begin);

 var videoFilePath = $"{videoId}.mp4";
 await System.IO.File.WriteAllBytesAsync(videoFilePath, memoryStream.ToArray());

 return NotFound("Video stream not found");
 }

how to download portion of video which was uploaded into AWS s3 bucket, though Nodejs SDKs
22 février 2024, par rama rangeswara reddyI 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 ");
});
