I am trying to capture camera live stream and make HLS stream from it. I am using Fantech Luminous C30 webcam. I get this error:

This is my code:

from ffmpeg_streaming import Formats,Bitrate, Representation, Size
video = ffmpeg_streaming.input('Fantech Luminous C30', capture = True)
_360p = Representation(Size(640, 360), Bitrate(276 * 1024, 128 * 1024))
_480p = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024))
_720p = Representation(Size(1280, 720), Bitrate(2048 * 1024, 320 * 1024))
hls = video.hls(Formats.h264())
hls.representations(_360p, _480p, _720p)
hls.output('C:\\Users\\ltadic\\Desktop\\camera_stream\\hls.m3u8')
It seems that FFmpeg reported an error while trying to capture the video from your webcam. There may be a problem with the path or name of the webcam given in the error message: "Fantech Luminous C30: No such file or directory". A possible reason for this error could be that FFmpeg is not able to find the webcam. Make sure that the webcam is connected to your computer and that the driver for the webcam is installed. Make sure FFmpeg is using the correct webcam. It could also be that FFmpeg does not have the required codecs or libraries to capture the video from the webcam. Make sure that FFmpeg is configured and compiled correctly and that all the required libraries are present. Did you tried to open your webcam with other applications?
