Hi. How did you get video out on your Bluefish? Can you post the plugin for that and some info how to use it? /Chr My Bluefish output plugin just passed the proof-of-concept stage, and I had to suspend my VLC project end of may because of other, more urgent needs. Apart from the VLC plugin (which I...

I'm now able to use vlclib in my BlueMotion graphics project to play files on the Bluefish444 card. There are several animation layers running simultaneous in separate threads, vlc is just one of these layers. When I send vlclib's play or stop command however, I see that all running (not vlc related...

contrib-20100428-win32-bin-gcc-4.4.2-runtime-3.17-only.tar.bz2 Should fix both issues. Is there a 'correct procedure' to upgrade contribs? i.o.w. should I delete something before untarring the new contribs? Or is it just a matter of tar xvjf contrib-20100428-win32-bin-gcc-4.4.2-runtime-3.17-only.ta...

Do you have installed the contribs correctly ? I'm using contrib-20100329-win32-bin-gcc-4.4.2-runtime-3.17-only.tar.bz2 This one always served me well with 1.1.0-pre1 Trying with a newer version: contrib-20100424-win32-bin-gcc-4.4.2-runtime-3.17-only.tar.bz2 DISASTER! :evil: It now stops with a lot...

I don't know how to report bugs otherwise, so i'm writing them here. This one in the mozilla project bothers me since 1.2.0 came online. It's an undefined symbol 'NPN_MemAlloc' Looks like this is supposed to be defined in support/npunix.c and support.npwin.c but when compiling natively with msys/min...

Now that vlcplayer happily plays video on my Bluefish card, I'm moving up to the next stage: Using libvlc in my MS Visual C++ 6.0 application. I now rebuilt the 1.2.0-git version from scratch, with the 'bluemotion" video out plugin. To get my project linked with libvlc I needed to do some modif...

Hi, I have this issue with make that pops up every now and then. When compiling vlc, instead of starting to compile, the "make" sometimes starts some kind of automake configuration, which always leads to a failed build if I let it run and forces me to start rebuilding from scratch with boo...

In the current (version <= 1.1) VLC architecture, the video output cannot control the framerate (unless you're willing to discard or duplicate some pictures, that is). If you want to pace decoding, then you need to use the stream output chain, akin to what the smem plugin is doing. Well, i'm very h...

Hi Belbear, I wrote a plugin using this very method but for much smaller external displays, so I'm not so sure how it would perform under the conditions you've outlined above. It's called svmem - Shared Video memory. You may find the plugin here with source and a test app (VLC 1.1 only). Hi Michael...

Is it your aim to use this IPC method in an output plugin to access the video data from an external process? Hi Michael! My aim is that an external process receives video from vlc to display it. This process allocates the memory and determines the maximum buffer size. Buffer size must be possible u...

I'm trying to use the (native) Windows API function OpenFileMapping to map a shared memory block between a clx video output plugin (which will write into the memory) and another Windows process that lalls CreateFileMapping. This works fine with a "vlc-emulator" proggy I compiled to test it...

I'm successfully building vlc now using msys native windows compiling. (up to the 1.2.0-git version) I'm now moving up to what it's all intended for: Writing a video output plugin that outputs video on my own BlueMotion layered graphic software that runs on Bluefish444 HD-SDI video cards. This toolk...

git over HTTP is crap. For a start, it's highly inefficient. Then it requires specific extra setup on the server, which typically fails to work because most people use git and don't test HTTP. Bottom line: use the native git protocol. Is that more helpful? Helpful in the way that anyone behind a co...

Please, you can update the wiki yourself!

Didn't realize I had the privilege. Working on it.

:D SUCCESS! :D Finally, make finished OK and without that damned "make: *** [all] Error 2" And it plays all my favourite movies too! Didn't test all the features yet, but in the end all that matters for me is the file player. What I had to do: -Removed the mingw 4.4.0 setup I had all the t...

Are you by chance using a MinGW build with the DW2 (Dwarf-2) unwinding instead of the SJLJ unwinding? As that's what that error indicates. Note that the proposed build of MinGW GCC 4.5.0 here contains the DW2 unwindings. MinGW DW2 should not be used to compile VLC. I use this MinGW build to compile...

Ok, I got the point , comparing to the working, downloaded vlc binary now. I took it to my home system now. (also Windows-only) Started all over again with installing msys and mingw, but at least here I can use git as it should be. So this one is from the git clone and not the tarball download. It a...

Try 'make package-win32-base'

Done that. Identical result: A dud exe. There must be something missing in this build, but what? Anyone can tell which files can give away what went wrong?

VLC compiles fine if the environment (including MinGw) is otherwise correctly configured.

How can I verify that? I followed the Win32CompileMSYSNew wiki as accurately as possible to set up the environment.
I'm essentially a Windoze programmer, all new to this msys/mingw thing.

Native Windows compilation = world of pain.

Please cross-compile with mingw.

Thought about that, but having to set up a whole linux system first (I don't have one) is a much further departure from my original plans.

Looks like the libtool issue. Check that 'global_symbol_pipe' in libtool (~line 155) is defined as below. global_symbol_pipe="sed -n -e 's/^.*[ ]\\([ABCDGIRSTW][ABCDGIRSTW]*\\)[ ][ ]*_\\([_A-Za-z][_A-Za-z0-9]*\\)\$/\\1 _\\2 \\2/p'" VLC compiles fine if the environment (including MinGw) is...

Use the git protocol. HTTP is loosy.

I would, if it worked. Company firewall is blocking the git port (among all other "not so well known" ports. And there are no exception requests accepted.

Hi, I proceeded with compiling vlc from the vlc 1.0.5 tarball (git doesn't work for me, see other post) I did everything exactly as in the Win32CompileMSYSNew wiki. After finally running the make, it produced a lot of .o files but failed to produce an exe. I did the bootstrap, config and make over a...

Hi, I'm totally new here, hoping this forum is acceptable for my problem I started trying to get vlc built using an MSYS/MinGW setup on Win XP, following the Win32CompileMSYSNew wiki. I also have installed msysgit and tortoisegit to get vlc sources, but it cannot get anything. The git:// protocol is...
