Windows questions.

[Jeff Shanab]

I am just returning to Gstreamer after a few years and a lot has changed.

I am on windows as it is the only machine I can remote into during this covid-19 time

The goal is to get the test-onvif-client working. I am having trouble finding things and am not sure if they are supposed to even be thre or not. I do not see the old separation of good bad and ugly plugins as separate install packages.

1) Are gst-plugins-bad only available on windows if you build from source?

2) Is there a separate package, artifactory, etc for plugin binaries and headers?

3) Are plugins on top of core and can be built in VS, or do we need the entire meson/MSYS2 build

   A) I do not know how to build GStreamer on Windows. Last try went horribly wrong with old instructions. :-(

additional info:

I did a "Complete" install of main and devel package.

If I gst-inspect | grep bad,  I see 25 plugins

If I remove onvifparse from the pipeline and make some other minor changes, I can run the app and get video.

I just started using Gstreamer on Windows also. I'm using the 1.18.2 MSVC
64-bit binaries from the GStreamer download page. I haven't messed with
altering GStreamer plugins themselves, so someone else will have to talk on
ONVIF support.

Doing a complete install of the runtime and dev installers, I have plugins
bad out of the box (I'm using h264parse). However, I don't see anything
onvif-related either, so may be OS-dependent?

The runtime installer only really has binary files (there are some other
misc items). To develop anything using GStreamer, you should also run the
development installer.  Just double-check your environment variables and
PATH to make sure everything is being found (easiest to just install to
C:\gstreamer). FYI, when I did a "Complete" install, the install directory
was something else; I had to change it to C:\gstreamer

To develop anything WITHIN GStreamer, I believe you have to build with
Cerbero and target Visual Studio. I used the build instructions in the
README without issue, it just took a while. Last I heard, Cerbero is how the
binaries are produced for the download page, so I think this is the
recommended build process. Last I tried meson, it sort of worked, but I
didn't mess with it that much.

I always had developer package downloaded.

I was able to get it to work.

The windows installation is missing a lot compared to the linux ones.

Plugins do not need to be built with meson, i was able to create a Visual Studio dll project, copy in the .h and .c files and build.

I only had to add the Defines that normally come from the build system in the plugins.c file where it calls the macro GST_PLUGIN_DEFINE

//@JFS normally from meson
#define VERSION "0.0.0"
#define PACKAGE "rtponvif"
#define GST_PACKAGE_NAME "GStreamer rtp onvif filter"
#define GST_PACKAGE_ORIGIN "http://gstreamer.net/"

Copying this to the folder along side the other plugins (in the gstreamer/lib folder NOT the bin folder pffft) allowed the example(test-onvif-client) to run.

I am now trying to create a single folder with all the dlls and plugins to allow it to be used during testing to exercise a server.

It is proving difficult. Even though all the dlls are there and Dependency walker is happy, it always bails out unable to create rtspsrc element.

probably a hidden dependency that is only at LoadLibrary time.
