Projects are compiled with VS2019 using .Net Core 9 | 2. ffmpeg.exe is not embedded in library binaries, you should pass a path to ffmpeg.exe explicitly in constructor 10 | 11 | The API changes for 0.2.0 Preview 12 | --- 13 | 14 | Engine class becomes obsolete. 15 | The MediaToolkit now exposes injectable **IMediaToolkitService**. 16 | 17 | Instantiating the service 18 | --- 19 | 20 | Using .Net Core dependency injection: 21 | ```csharp 22 | var ffmpegFilePath = @"C:\ffmpeg\ffmpeg.exe"; 23 | var serviceProvider = new ServiceCollection() 24 | .AddMediaToolkit(ffmpegFilePath) 25 | .BuildServiceProvider(); 26 | ... 27 | var service = serviceProvider.GetService(); 28 | ``` 29 | 30 | Directly: 31 | ```csharp 32 | var ffmpegFilePath = @"C:\ffmpeg\ffmpeg.exe"; 33 | var service = MediaToolkitService.CreateInstance(ffmpegFilePath); 34 | ``` 35 | 36 | Getting the metadata 37 | --- 38 | 39 | This task uses ffprobe to extract the metadata. 40 | ```csharp 41 | var metadataTask = new FfTaskGetMetadata(videoPath); 42 | var metadataResult = await service.ExecuteAsync(metadataTask); 43 | ``` 44 | 45 | Saving the thumbnail in a file 46 | --- 47 | 48 | ```csharp 49 | var saveThumbnailTask = new FfTaskSaveThumbnail( 50 | videoPath, 51 | thumbnailPath, 52 | TimeSpan.FromSeconds(10) 53 | ); 54 | await service.ExecuteAsync(saveThumbnailTask); 55 | ``` 56 | 57 | Getting the thumbnail data 58 | --- 59 | This task returns byte[] with the thumbnail data instead of saving it to a file. 60 | You can pass null to the frame size to let ffmpeg guess the frame dimensions. 61 | 62 | ```csharp 63 | var options = new GetThumbnailOptions 64 | { 65 | SeekSpan = TimeSpan.FromSeconds(10), 66 | OutputFormat = OutputFormat.Gif, 67 | PixelFormat = PixelFormat.Gray 68 | }; 69 | var getThumbnailTask = new FfTaskGetThumbnail( 70 | videoPath, 71 | options 72 | ); 73 | await service.ExecuteAsync(getThumbnailTask); 74 | ``` 75 | 76 | 77 | ...From MediaToolkit (original) 78 | --- 79 | 80 | MediaToolkit provides a straightforward interface for handling media data, making tasks such as converting, slicing and editing both audio and video completely effortless. 81 | 82 | Under the hood, MediaToolkit is a .NET wrapper for FFmpeg; a free (LGPLv2.1) multimedia framework containing multiple audio and video codecs, supporting muxing, demuxing and transcoding tasks on many media formats. 83 | 84 | Contents 85 | --------- 86 | 87 | 1.
