Using my own bytearray as input ( imem:// libVLC )

[eduard]

Hello,

I want to stream my own manipulated stream of images to another computer. For this i want to use vlc, so my step 1, i started with opening a avi from my system, which i, with succes and very easy, used to steam on the network and could pickup with another instance of vlc.

In my step2, i try to use my own data(the manipulated image stream) and display them in vlc. After some googling and irc i found out that the "new memory input (imem) access and access_demux" would help me with this trick in combination with libVLC.

Can i get some pointers to documentation / sample code (preferable in C# but C++ is also fine), to show me how to display my image-byte-data (and from what i read, using the imem module to send data to vlc and call the (callback)functions).

References which didnt help me anyfurther:
- (C# / imem) viewtopic.php?f=32&t=85451
- IRC channel on 2011-01-19 : i learned here not to use the commandline, but libVLC
- fake:// viewtopic.php?f=14&t=47779
- imem module: http://www.videolan.org/developers/vlc/ ... em_8c.html

Platform:
- Windows 7
- Vlc Mediaplayer 1.1.5

Please let me know

Seems like a bit of a mystery

I would also like to know what the possibilities are, and how to use it.

Nobody wrote an API to imem, that's the problem.

So at this time, it's not possible to use it, I understand.

That still leaves me with the question: what exactly would it do, once there is an API? I mean, does it basically do the same as opening a file (a wrapper + elementary streams), but the data is in memory?

Or is it something that can read 'raw' image data, and pass it on, so it can be encoded and/or streamed. What I mean is, a similar mechanism as decoding video frames to memory (using lock and unlock callbacks), but the other way around? Or maybe what I am describing is something totally different, and in that case, can LibVLC be used to create a video-stream from raw in-memory frames (for instance by calling add_frame() on every new frame that should be appended to the stream)?

I hope I made myself clear...

It depends on how the API is written really. In principle, it could provide a callback for VLC to get data.
