Good day,

I would like to stream a video from my capture device with directshow. When using the VLC Player I can go
> Media > Stream... > Capture Device:
Capture mode = DirectShow
Video device name = Datapath VisionSD4+1S 01
> Stream > Play
The player will then display the video feed.

I tried the basic:

Code: Select all

import vlc

i = vlc.Instance()
p = i.media_player_new()
m = i.media_new('dshow://', 'dshow-vdev=Datapath VisionSD4+1S 01', 'dshow-adev=none', 'live-caching=300')
p.set_media(m)
p.play()

p.play() return 0 with an error:

Code: Select all

0005>>> a000000005a9e00] main input error: Your input can't be opened
[00000000005a9e00] main input error: VLC is unable to open the MRL 'dshow://'.

I have tried it in various other ways but receive the same error. Any ideas?

How can I grab the video frames into an array for post processing?

Please assist?

Did you try adding the ":" before dshow-vdev?

Yes I have tried almost all configuration, such as using the add_option or '--' addition. Is there a way that I can check what is going wrong?

missing " " around the device name?

No, same error, I played around with the various combination as well. A note, when I create the instance I receive a

Warning: option --plugin-path no longer exists.

Hello
I am trying to stream http audio,
When I use play() it also plays captured audio from my speakers.
There is an option in windows VLCPlayer aplication, "stream" instead of "play". Is there any at python?

This is my code:

Code: Select all

import vlc

#define VLC instance
instance = vlc.Instance("--sout '#transcode{vcodec=none,acodec=mp3,ab=128,channels=2,samplerate=44100}:std{access=http,mux=mp3,dst=:8080}' :no-sout-all :sout-keep")

#Define VLC media
transcoder = instance.media_player_new()

media=instance.media_new('dshow://','dshow-vdev=None' ,'dshow-adev=', 'live-caching=30')
#Set player media
transcoder.set_media(media)

#Play the media
transcoder.play()
while 1:
    pass
