How to detect the url's availablility automatic?

[jackhuang]

As subject. I have a long url list in a text file, I need verify the availability of the network url automatic. It should verify the network url and return the status of the url's availablility.
Does any solution can be provided?

[Rémi Denis-Courmont]

In general, the only way to check that an URL works is to try to play it...

[jackhuang]

yes, I know the command for VLC to play a url, but not found which cmd can check the playback is ok.
Dose any api can help this?

Depends on the interface you use.

Bingo. I use the Python to finish the function. Python binding the libvlc.dll. I would improve the component and package it executable.
Actually, My initial purpose is automatic check the network channels and get available channels. Because I have a Android TV, it can play the
network channel stream, I get a channel list about 10000 channels url. So I could use the tool to get useful channel import my TV.
Dose anyone how to add it as a VLC extensions?
