gsvideo pipeline 2.0b6 64 bit windows

in Contributed Library Questions • 11 months ago

Hi guys,

I'm having some trouble getting gsvideo, specifically the pipeline, to work. Here's my setup:

Windows 7 Professional 64bit

GStreamer (32bit? I think?) from OSSBuild ( http://code.google.com/p/ossbuild/)

Processing 2.0b6 for 64bit windows

GSVideo 1.0

Opening and running the example gsvideo for Pipeline > Raw give an Unsatisfied Link Error:

GSVideo version: 1.0.0
Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError: Could not load library gstreamer-0.10

GStreamer by default installs in the x86 Program Files directory, which is generally where 32 bit apps go, I copied the entire gstreamer folder into the "Program Files" directory folder, and updated my path variables to point to that version. Same results.

Anyone have any insight to this? I've scoured the interwebs for a x64 installer for GStreamer, but it seems that there are only instructions to build from the sdk, which I've tried without success.

Has anyone built the 64bit version of gstreamer that I could get my hands on, or have any advice on how to get this to work in a pure-64 bit setup? or point me in the right direction at least :)

Thanks!

I think the GStreamer libs from OSSBuild are 32 bits, so they won't run from a 64 bits JVM. But the GSVideo package includes a 64 bit build of GStreamer. Can't you use those instead of the OSSBuild one?

Hi Andres,

I saw that in the library folder. How would I get processing to recognize that version?

ok, tried removing all the ossbuild stuff, and now it seems like it is seeing your version in processing. Which GStreamer plugins (good, bad, ugly) are in your version? I'm seeing this error now:

Exception in thread "Animation Thread" org.gstreamer.GstException: no element "wininetsrc"
at org.gstreamer.Pipeline.launch(Pipeline.java:132)

at processing.core.PApplet.run(PApplet.java:2006)
at java.lang.Thread.run(Thread.java:662)

Here's my pipeline string:

pipeline = new GSPipeline(this, "wininetsrc location=http://10.35.3.119:1234 ! oggdemux ! theoradec ! ffmpegcolorspace");

Can I change the 'wininetsrc' to something else? I'm really not familiar with how to form the pipeline string, I got to this one through lots of trial and error and it seems to be one of the only ways I could get everything to work.

Thanks!

Bump!

Im in the process of trying to build the 64 bit windows gstreamer plugins. I'm following the tutorial here: http://gstreamer.freedesktop.org/wiki/BuildGStreamerWithMinGWAndMsys

but I'm hitting a lot of walls as I'm not very familiar with building libs (or windows dev in general).

Has anyone already done this build process and could point me to, or provide the compiled libraries?

Thanks!

The gstreamer libraries included in GSVideo and the new default video library in Processing 2.0 are built from base, good, bad and ugly packages. But some specific plugins were left out either because they had compilation errors or introduced many additional dependencies. Either one, the wininetsrc somehow didn't make into the final binaries.

The compilation process is quite involved, particularly on windows. In fact, for the latest windows binaries in GSVideo I used a cross-compilation approach (built windows libs from linux). But I'd recommend you to try to use the new binary packages from the recently launched GStreamer SDK. The idea is to use their binaries instead of our own for future Processing/GSVideo releases, but haven't had the time to work on it.
