Encoding MJPEG from webcam in UWP development with C#
24 avril 2018, par Federico Parrathis is my first question in StackOverflow.
How can I encode video being captured from webcam as a MJPEG using C# in UWP enviroment (Visual Studio 2017) ?
Perhaps using FFMPEG or DirectShow ? Any particular bindings required to use them in UWP ?I’ve been through these walk-throughs trying to go the official way using MediaCapture :
https://docs.microsoft.com/en-us/windows/uwp/audio-video-camera/basic-photo-video-and-audio-capture-with-mediacapture
https://docs.microsoft.com/en-us/uwp/api/windows.media.capture.mediacaptureAccording to Microsoft though, there is no MJPEG encoder included in MediaEncoder (only decoder) : https://docs.microsoft.com/en-us/windows/uwp/audio-video-camera/supported-codecs
About FFMPEG UWP integration, I found this :
https://github.com/Microsoft/FFmpegInterop
https://blogs.windows.com/buildingapps/2015/06/05/using-ffmpeg-in-windows-applications/#HHYbWAVcM7LhkvYZ.97But it’s geared towards decoding, and I want to encode.
Just in case someone is wondering, I want to use MJPEG for Two reasons :
1) less CPU intensive (much less) because it doesn’t do inter-frame compression, means my Surface Pro (and other similar computers) will keep quiet without fans running like crazy
2) I need all frames (i.e. not one every 30) to be crystal clear because of an algorithm I need to run on each of them afterAny pointers would be greatly appreciated.
Thank you,
Federico
