Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

What are the pros and cons of creating your own streaming server (FFMPEG and Apache) vs using a streaming service such as Wowza ? [closed]
9 novembre 2023, par Luke LopezI am researching creating my own streaming server (taking rtsp streams and transcoding and broadcasting as m3u8) and I am wondering what the pros and cons of a paid vs a build your own service are.
I have not tried anything as this is not applicable to my question

Video streaming error : Uncaught (in promise) NotSupportedError : Failed to load because no supported source was found
18 septembre 2024, par AizenHere is my problem : I have one video src 1080p (on the frontend). On the frontend, I send this video-route to the backend :


const req = async()=>{try{const res = await axios.get('/catalog/item',{params:{SeriesName:seriesName}});return {data:res.data};}catch(err){console.log(err);return false;}}const fetchedData = await req();-On the backend i return seriesName.Now i can make a full path,what the video is,and where it is,code:


const videoUrl = 'C:/Users/arMori/Desktop/RedditClone/reddit/public/videos';console.log('IT VideoURL',videoUrl);


const selectedFile = `${videoUrl}/${fetchedData.data.VideoSource}/${seriesName}-1080p.mp4`
console.log(`ITS'S SELECTED FILE: ${selectedFile}`);


Ok, I have my src 1080p, now is the time to send it to the backend :


const response = await axios.post('/videoFormat', {videoUrl:selectedFile})console.log('Это консоль лог путей: ',response.data);const videoPaths = response.data;


Backend takes it and FFMpqg makes two types of resolution,720p and 480p,save it to the temp storage on backend, and then returns two routes where these videos stores


async videoUpload(videoUrl:string){try{const tempDir = C:/Users/arMori/Desktop/RedditClone/reddit_back/src/video/temp;const inputFile = videoUrl;console.log('VIDEOURL: ',videoUrl);


const outputFiles = [];
 
 await this.createDirectories(tempDir); 
 outputFiles.push(await this.convertVideo(inputFile, '1280x720', '720p.mp4'));
 outputFiles.push(await this.convertVideo(inputFile, '854x480', '480p.mp4'));
 console.log('OUTUPT FILES SERVICE: ',outputFiles);
 
 return outputFiles;

 }catch(err){
 console.error('VideoFormatterService Error: ',err);
 
 }
}

private convertVideo(inputPath:string,resolution:string,outputFileName:string):Promise<string>{
 const temp = `C:/Users/arMori/Desktop/RedditClone/reddit_back/src/video/temp`;
 return new Promise(async(resolve,reject)=>{
 const height = resolution.split('x')[1];
 console.log('HIEGHT: ',height);
 
 const outputDir = `C:/Users/arMori/Desktop/RedditClone/reddit_back/src/video/temp/${height}p`;
 const outputPath = join(outputDir, outputFileName);
 const isExists = await fs.access(outputPath).then(() => true).catch(() => false);
 if(isExists){ 
 console.log(`File already exists: ${outputPath}`);
 return resolve(outputPath)
 };
 ffmpeg(inputPath)
 .size(`${resolution}`)
 .videoCodec('libx264') // Кодек H.264
 .audioCodec('aac') 
 .output(outputPath)
 .on('end',()=>resolve(outputPath))
 .on('error',(err)=>reject(err))
 .run()
 
 })
}

private async createDirectories(temp:string){
 try{
 const dir720p = `${temp}/720p`;
 const dir480p = `${temp}/480p`;
 const dir720pExists = await fs.access(dir720p).then(() => true).catch(() => false);
 const dir480pExists = await fs.access(dir480p).then(() => true).catch(() => false);
 if(dir720pExists && dir480pExists){
 console.log('FILES ALIVE');
 return;
 }
 if (!dir720pExists) {
 await fs.mkdir(dir720p, { recursive: true });
 console.log('Папка 720p создана');
 }
 
 if (!dir480pExists) {
 await fs.mkdir(dir480p, { recursive: true });
 console.log('Папка 480p создана');
 }
 } catch (err) {
 console.error('Ошибка при создании директорий:', err);
 }
}
</string>

Continue frontentd code :


let videoPath;

if (quality === '720p') {
 videoPath = videoPaths[0];
} else if (quality === '480p') {
 videoPath = videoPaths[1];
}

if (!videoPath) {
 console.error('Video path not found!');
 return;
}

// Получаем видео по его пути
console.log('VIDEOPATH LOG: ',videoPath);
 
const videoRes = await axios.get('/videoFormat/getVideo', { 
 params: { path: videoPath } ,
 headers: { Range: 'bytes=0-' },
 responseType: 'blob'
 });
 console.log('Video fetched: ', videoRes);
 const videoBlob = new Blob([videoRes.data], { type: 'video/mp4' });
 const videoURL = URL.createObjectURL(videoBlob);
 return videoURL;
 /* console.log('Видео успешно загружено:', response.data); */
 } catch (error) {
 console.error('Ошибка при загрузке видео:', error);
 }
}


Here I just choose one of the route and make a new GET request (VideoRes), now in the controller in the backend, I'm trying to do a video streaming :


@Public()
 @Get('/getVideo')
 async getVideo(@Query('path') videoPath:string,@Req() req:Request,@Res() res:Response){
 try {
 console.log('PATH ARGUMENT: ',videoPath);
 console.log('VIDEOPATH IN SERVICE: ',videoPath);
 const videoSize = (await fs.stat(videoPath)).size;
 const CHUNK_SIZE = 10 ** 6;
 const range = req.headers['range'] as string | undefined;
 if (!range) {
 return new ForbiddenException('Range не найденно');
 }
 const start = Number(range.replace(/\D/g,""));
 const end = Math.min(start + CHUNK_SIZE,videoSize - 1);

 const contentLength = end - start + 1;
 const videoStream = fsSync.createReadStream(videoPath, { start, end });
 const headers = {
 'Content-Range':`bytes ${start}-${end}/${videoSize}`,
 'Accept-Ranges':'bytes',
 'Content-Length':contentLength,
 'Content-Type':'video/mp4'
 }
 
 res.writeHead(206,headers);

 // Передаем поток в ответ
 videoStream.pipe(res);
 

 // Если возникнет ошибка при стриминге, логируем ошибку
 videoStream.on('error', (error) => {
 console.error('Ошибка при чтении видео:', error);
 res.status(500).send('Ошибка при чтении видео');
 });
 } catch (error) {
 console.error('Ошибка при обработке запросов:', error);
 return res.status(400).json({ message: 'Ошибка при обработке getVideo запросов' });
 }
 }


Send to the frontend


res.writeHead(206,headers);


In the frontend, I make blob url for video src and return it


const videoBlob = new Blob([videoRes.data], { type: 'video/mp4' });const videoURL = URL.createObjectURL(videoBlob);return videoURL;


And assign src to the video :


useVideo(seriesName,quality).then(src => {
 if (src) {
 console.log('ITS VIDEOLOGISC GOIDA!');
 if(!playRef.current) return;
 
 const oldURL = playRef.current.src;
 if (oldURL && oldURL.startsWith('blob:')) {
 URL.revokeObjectURL(oldURL);
 }
 playRef.current.pause();
 playRef.current.src = '';
 setQuality(quality);
 console.log('SRC: ',src);
 
 playRef.current.src = src;
 playRef.current.load();
 console.log('ITS VIDEOURL GOIDA!');
 togglePlayPause();
 }
 })
 .catch(err => console.error('Failed to fetch video', err));


But the problem is :




Vinland-Saga:1 Uncaught (in promise) NotSupportedError : Failed to load because no supported source was found




And I don't know why...


I tried everything, but I don't understand why src is incorrect..

lavc/vvc : Don't check motion estimation region for IBC
28 novembre 2024, par Frank Plowmanlavc/vvc : Don't check motion estimation region for IBC
The final parameter of check_available determines whether the motion
estimation region constraints imposed in section 8.5.2.3 of H.266 (V3)
on MVP candidates apply to the current candidate or not. In the case of
IBC spatial merge candidates they do not, as their availability is
dependent only on the criteria described in sections 8.6.2.3 and 6.4.4,
which do not include this constraint on the motion estimation region.Signed-off-by : Frank Plowman <post@frankplowman.com>
