Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.

Crossdevice encoding static file to stream in browser using FFMPEG (segmented h264 ?)
20 mars 2014, par VprnlI'm building a mediacenter application in NodeJS which is going pretty ok.
(you can check it out on Github : https://github.com/jansmolders86/mediacenterjs )I'm using FFMPEG to transcode local (static) movies to a stream which I then send to the browser.
At first I used h264 with Flash which worked in browsers, but I really need it to work on Android an iOS (so no Flash) and preferably working on a Raspberry Pi.
But getting it to play on all devices is driving me absolutely insane !
I have all these bits of the puzzle I've gathered from countless hours reading articles, tutorials and stack overflow posts, which led me to the conclusion that I need to produce the following :
- Use video codec H264 to transcode to MP4
- Move the moovatom '-movflags' to make a MP4 streamable
- Segment the stream so Apple can play the stream as well.
But getting nowhere with this. Every time I produce a series of FFMPEG settings that either don't work, or work on some devices rather than all.
Some of my failed attempt where :
My flash attempt -> Main problem (not running in IOS) :
'-y','-ss 0','-b 800k','-vcodec libx264','-acodec mp3'\
'-ab 128','-ar 44100','-bufsize 62000', '-maxrate 620k'\
metaDuration,tDuration,'-f flvmy HLS attempt -> Main problem (not running in browser) :

'-b:a 160000','-ac 2','-f hls','-hls_time 10','-hls_list_size 6'\
'-hls_wrap 18','-start_number 1'My MP4 attempt -> Main problem (duration is shortened and the later part of the video is speeding by)

.writeToStream(res, function(retcode, error){
if (!error){
console.log('file has been converted succesfully',retcode .green);
}else{
console.log('file conversion error',error .red);
}
});So to conclude this very long and code heavy question :
I hope this does not come off as a lazy request, but could someone show/explain to me which FFMPEG settings could/should work on all platforms (modern browsers, Android and iOS) producing a stream of a static file which I can send to a HTML5 player.
[EDIT] what I need if a generic option isn't available
And if this is not possible as some posts might suggest, I would love to see a set of FFMPEG settings that get's the job done properly as far as mp4 streaming is concerned. (e.g encoding a streamable mp4).
The streaming mp4 needs the following
- A shifted moovAtom
- It needs to be h264
Thanks very much for your help !

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..

 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..
