[gst-devel] gstreamer ossbuild BETA2 misssing pieces

Fri Apr 9 17:25:44 CEST 2010

I'm lost in the #include spaghetti

the 0.10.5.1 release I have installed on W2K has: 

$ pkg-config --cflags --libs gstreamer-0.10
-mms-bitfields -Ic:/gstreamer/include/gstreamer-0.10 -Ic:/gstreamer/include/glib-2.0 -Ic:/gstreamer/lib/glib-2.0/include -Ic:/gstr
eamer/include/libxml2  -Lc:/gstreamer/lib -lgstreamer-0.10 -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lxml2 -lglib-2.0 -lintl

There is an iconv.h file in C:\gstreamer\include and appears to be identical to the version I found in your link.

It would seem something assumes iconv.h has been previously included when it isn't, or is looking for it in the "wrong" place, hence the breakage.  But the oosbuild site shows 1472 downloads for GStreamerWinBuild-0.10.5.1.exe, so how is it I'm the first to have this issue?
Was it implicitly assumed I'd istalled GStreamerWinBuild-0.10.5-dev.exe first? (only 82 downloads listed)

A "known to work" recipe in a top level README at the download site about how to install on a virgin system would be a big help.  I've tried 0.10.5.1 and the BETA2 on two different "virgin" systems and compiling gstreamer sample code with the msys gcc fails miserably on both :(

Or did everyone else so what I'm tempted to do and just throw up my hands, join MSDN and use Directshow? :)

My image processing is pure C and during the port from the original PowerMac code I made sure it ran on Linux and Win32.   If using gstreamer to capture the data and display the real-time processing output is really viable on Win32, and possibly Mac OS X, it makes a compelling case for the effort to learn and use gstreamer.   But unless I can prove I can capture the input stream on Windows, its too big a leap of faith for me, although I am leaning towards using gstreamer as opposed to using straight v4l2 and Xdisplay code again, like I did in the initial version (done in 2006, on Ubuntu 6.06 and has worked quite well, although there are some limitations I'd like to overcome in version 2).

Linux remains my primary target, Ubuntu 10.04 specifically, and building my gstreamer samples on their BETA is going pretty smoothly although there seems to be an issue with finding their gst/interfaces/tuner.h when I try to compile the code that switches the capture card source input.

I've also looked at using MLT and VLC, but their documentation and sample code situation appears even worse than with gstreamer. :(

I've still got issues trying to get a capture device running on my XP notebook, it'd be nice to be able to build some samples once I get this resolved.

My I suggest instead of fighting the msi installer,  just *.7z the working gstreamer tree like done with the msys_v11.7z which didn't seem to care where I unzipped it, and document any needed environmental variable changes  for different drives or unzip paths.

I'll update it as soon as possible.

It's still a BETA, and we are actually working on the installers to
configure properly .pc files according to the installation path.
For the moment I suggest you to use the 0.10.5 release. As you stated
in a previous mail, iconv.h is missing, but you can grab a copy from
here: http://code.google.com/p/ossbuild/source/browse/trunk#trunk/Shared/Build/Windows/Win32/include

Cheers,
