here is my relevant .net application code


private async Task<mediametadata> GetVideoThumbnailAsync(IFormFile file,int frameTarget)
 {
 var fileName = file.FileName;
 var filePath = Path.Combine(_rootPath, "videos", fileName);
 var fileExtension = Path.GetExtension(filePath);
 
 // the xabe wrapper works with only mp4 extension to create thumbnail , if the file is any other format first convert it to
 //the mp4 format and then goahead with creating the thumbnail. 
 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);
 }
 Console.WriteLine(Path.Combine(_rootPath,"ffmpeg"));
 FFmpeg.SetExecutablesPath(Path.Combine(_rootPath,"ffmpeg"));
 IMediaInfo mediaInfo = await FFmpeg.GetMediaInfo(filePath);
 var videoDuration = mediaInfo.VideoStreams.First().Duration;
 IConversion conversion = await FFmpeg.Conversions.FromSnippet.Snapshot(filePath, thumbnailImagePath , TimeSpan.FromSeconds(frameTarget));
 IConversionResult result = await conversion.Start();
 MediaMetadata media = new MediaMetadata();
 media.DurationSeconds=Convert.ToInt32(videoDuration.TotalMilliseconds);
 // media.DurationSeconds=10;
 media.ThumbnailImagePath= thumbnailImagePath;
 return media;
 
 }

could you help me out with this ..many thanks

x86 : checkasm : check for or handle missing cleanup after MMX instructions
11 décembre 2015, par Janne Grunaux86 : checkasm : check for or handle missing cleanup after MMX instructions
Not every asm routine is expected clear the MMX state after returning.
It is however a requisite for testing floating point code in checkasm.
Annotate functions requiring cleanup with declare_func_emms() and issue
emms after the call. The remaining functions are checked for having a
cleared MMX state after return.
