MediaToolkit provides a straightforward interface for handling media data, making tasks such as converting, slicing and editing both audio and video completely effortless.
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.
- Resolving metadata
- Generating thumbnails from videos
- Transcode audio & video into other formats using parameters such as:
Bit rateFrame rateResolutionAspect ratioSeek positionDurationSample rateMedia format
- Convert media to physical formats and standards such as:
- Standards include:
FILM,PAL&NTSC - Mediums include:
DVD,DV,DV50,VCD&SVCD
- Standards include:
- Supports custom FFmpeg command line arguments
- Raising progress events
Install MediaToolkit from NuGet using the Package Manager Console with the following command (or search on NuGet MediaToolkit)
PM> Install-Package MediaToolkit
- Retrieve metadata
- Perform basic video conversions
- [Grab thumbnail] (#grab-thumbnail-from-a-video)
- Convert from FLV to DVD
- Convert FLV to MP4 using various transcoding options
- [Cut / split video] (#cut-video-down-to-smaller-length)
- Subscribing to events
