I have to record selected webcam to file but i get video from default webcam (no matter which i describe in media option)
When i use VlcPlayer to record any of existing camera i get proper camera, but when try do the same from my application i get video from default webcam. What i do wrong ?
parameters from VlcPlayer: :dshow-vdev=Logitech StreamCam :dshow-adev= :live-caching=100
my app code:
Core.Initialize();
using var libVLC = new LibVLC(enableDebugLogs: true);
using var media = new Media(libVLC, "dshow://",FromType.FromLocation);
using var mediaPlayer = new MediaPlayer(libVLC);
// :dshow-vdev=Logitech StreamCam :dshow-adev= :live-caching=100 - copied from VlcVideoPlayer
media.AddOption(" :dshow-vdev=Logitech StreamCam :dshow-adev= :live-caching=100");
// i also try this format without success
// media.AddOption(" :dshow-vdev=\"Logitech StreamCam\" :dshow-adev=none :live-caching=100");
// media.AddOption(" :dshow-vdev='Logitech StreamCam' :dshow-adev=none :live-caching=100");
// media.AddOption(" :dshow-vdev=Integrated Camera :dshow-adev=none :live-caching=100");
media.AddOption(":sout=#duplicate{dst=display,dst=transcode{vcodec=mp4v,acodec=mpga,vb=800,ab = 128,deinterlace},dst=std{access=file,mux=asf,dst=xyz.mp4}}");
mediaPlayer.Play(media);
System.Threading.Thread.Sleep(10000);
mediaPlayer.Stop();
The second question - recorded file is very large (2 GB per 10 seconds), how to set transcoding to get it compressed but good quality ?
