checkasm : Check register clobbering on arm
30 décembre 2015, par Martin Storsjöcheckasm : Check register clobbering on arm
Use two separate functions, depending on whether VFP/NEON is available.
This is set to require armv5te - it uses blx, which is only available
since armv5t, but we don’t have a separate configure item for that.
(It also uses ldrd, which requires armv5te, but this could be avoided
if necessary.)Signed-off-by : Martin Storsjö <martin@martin.st>

From URL of Video GetThumbnail Using Nreco
8 février 2016, par Muhammad Abid FahadI working on a sharepoint project in which i have to upload the videos in the document library as videoset. after creating a video set i have have to upload the video and fetch the thumbnail from the video and upload it. video is uploaded succesfully using
spfile = item.Folder.Files.Add(fuUpload.FileName, fuUpload.PostedFile.InputStream, true);I am using using Nreco to get thumbnail from the video. However my code works fine on local machine but its giving error "http://mysite/Download/abc/abc.mp4 : Server returned 401 Unauthorized (authorization failed) (exit code : 1)" when i am using my application from other pc browsers.
ffMpeg.GetVideoThumbnail(videoPath, ms, 10) ; the error line.
here is the code i am using
private MemoryStream SaveThumbnail(string videoPath)
{
MemoryStream ms;
try
{
videoPath = "http://mysitehttp/Download/abc/abc.mp4"
ms = new MemoryStream();
SPSecurity.RunWithElevatedPrivileges(delegate() {
var ffMpeg = new NReco.VideoConverter.FFMpegConverter();
ffMpeg.GetVideoThumbnail(videoPath, ms, 10);
});
}
catch(Exception ex)
{
throw ex;
}
return ms;

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..
