VLC remotely control from C#

Question

i\'m trying to control the VLC Media Player from C#. I tried getting a handle on the window with the FindWindow() command from .Net but as i found out the name of the window

Answer 1

Have you looked at libvlc

You might be able to wrap that up in a library and interact with VLC through that.

Answer 2

As Eoin mentioned, libvlc can be used to interact with VLC. As a C# user, you may want to try the .NET bindings offered by the libvlc-sharp project.

Edit: Seems like this project has not been maintained for years. I will leave the link anyway, in case you wish to take a look at it and maybe put some of its source to use.

Answer 3

How use libvlc in C++ http://unick-soft.ru/art/files/libvlcProject.zip I think, use libvlc in C# very similar.

Answer 4

I have some code that is able to control it using sockets on the RC interface. This worked to a degree but has a lot of quirks. go to full screen seems to do nothing for a few seconds after play is invoked. Overall it sort of works.

The other options are:

Write a DirectDraw filter (very hard) but once this is done VLC can be used instead of or in conjunction with FFMPEG. Existing code that drives media player could use vlc.

Write an interop wrapper for libvlc, recently the VLC team split out libvlccore from libvlc so to the best of my knowledge all the interop is out of date. Once you write a wrapper you could embed vlc in a windows app. (if you need to support x64 you need to compile these libs under x64.

Look through the VLC code and find out if there is a way to send these windows messages.

EDIT This appears to have come out this week.

Answer 5

If what you are trying to do is control a previously running executable, check out the Process class to enumerate through all the current processes or do it by name. Check the executable to match vlc.exe. You can then get a handle to the main window and do some P/Invoke to send messages as you are doing with your other executables. This is obviously riddled with potential problems such as if the there are changes to the keyboard shotcuts.

Answer 6

There's also the rc interface and even a telnet one: http://wiki.videolan.org/Console

However, I'd prefer libvlc if possible.
