That is sample use: public IConversion SetSeek(TimeSpan? seek) Return new TimeSpan(0, hours, minutes, seconds, milliseconds) īut honestly, you do not have to know what underneath those methods. Public static TimeSpan ParseFFmpegTime(this string text) OnProgress events allow redirect FFmpeg output to user and inform him about progress.Ĭonversion.OnProgress += (sender, args) => IConversion provides events to handle FFmpeg output. All parameters passed to it are overrided by default values. Method IConversions.Clear() sets IConversion to untouched state.
string outputPath = Path.ChangeExtension(Path.GetTempFileName(), ".mp4") Stream object could be use more than once. IStream audioStream = ()Īlmost all methods in streams return specific stream (IAudioStream, IVideoStream etc.). IMediaInfo mediaInfo = await FFmpeg.GetMediaInfo(Resources.MkvWithAudio)
This could be done also by: string outputPath = Path.ChangeExtension(Path.GetTempFileName(), ".mp4") IConversionResult result = await snippet.Start() Var snippet = (Resources.MkvWithAudio, output) Sample below shows basic conversion video file from mkv to mp4 format: string output = Path.Combine(Path.GetTempPath(), Guid.NewGuid() + ".mp4") 5.2. is the main class to handle FFmpeg conversions. Users can skip – map and let ffmpeg handle stream selection. It also sets the number of output audio streams.įinally, the -map flag in step 5 allows for a custom stream selection in each output file if there are multiple. Similarly, a (default is 0) sets the number of audio streams in each section. Next, we follow with v (default is 1), which sets the number of output video streams. In step 4, the number of files we want to join is in the value of n (default is 2). Map the resulting audio and video streams to the output.Select the actual streams in a specific order: video and audio from the first, second, and third file.Use -filter_complex to select streams from the input files.Here’s a quick rundown of what’s going on in the command:
To explain the contact filter, we’ll use start.mkv, body.mkv, and rear.mkv with a single audio stream: $ ffmpeg -i start.mkv -i body.mkv -i rear.mkv -filter_complex \
