xabe.ffmpeg not working in azure app service
28 décembre 2020, par Sripathi RajaI have a .net core application which generates video thumbnails for uploaded videos. I am using xabe.ffmpeg for this . The code runs fine in the local system and Iam able to generate the thumbnails . I have containerized this application and pushed it to azure app service . But when the code is deployed on azure app service its throws an error . I have placed the ffmpeg.exe ,ffprobe.exe , ffplay.exe inside a folder ffmpeg in wwwroot folder .
the app service logs give this error


the first line is the path : /app/wwwroot/ffmpeg

 var thumbnailImageName = fileName.Replace(fileExtension, ".jpg");
 var thumbnailImagePath = Path.Combine(_rootPath, "thumbnails", thumbnailImageName);
 
 using (Stream fileStream = new FileStream(filePath, FileMode.Create)) {
 
 await file.CopyToAsync(fileStream);

ffmpeg exit code 429496724 when opening file with {} in name
16 février, par Holly WilsonI'm trying to write a program that will read the names of files in a directory, and parse them for info which it will then write into that file's metadata (seems pointless, I know, but it's more of a trial run for a larger project. If I can figure this out, then I'll be ready to move on to what I actually want to do).
All of my filenames are formatted :


Title, Article* - Subtitle* Cut* [Year]
*if present


The four test videos I'm using are titled :


Test Video 1 [2000]


Test Video 2, A [2000]


Test Video 3 Test Cut [2000]


Test Video 4 - The Testening [2000]


The code seems to be working fine on videos 1, 2, & 4 ; but video 3 is causing me a lot of headache.

I've tried so many different solutions in the sanitizeFilePath function. Escaping the {} characters (as included below), escaping all non-alphanumeric characters, putting the filepath in quotes, etc. VSCode's CoPilot is just pulling me round in circles, suggesting solutions I've already tried.

How to combine multiple video blobs in js without gap ?
5 septembre 2021, par Pouria MoosaviI have an array of urls. I download them with
fetchand then get blob from each response withawait res.blob(). I need to concat all these blobs together to make a full video out of it, I tried to push each blob into an array and make a filenew File(blobArray, "test")but the result has a gap between each blob.

I've tried to save each blob as a separate file and concat them with
ffmpeg -f concat -safe 0 -i text -c copy out3.mp4and the result was perfect. So I know that my blobs are correct and the problem is how I am combining them together.

This is my full code :
