Regarding gst ducati plugins

Carol Suman Pinto

Hi,

I'm using OMAP4460, and trying to use gst ducati plugins for video playback.

My pipeline looks like,

# gst-launch-0.10  filesrc location= /home/waka.mp4 ! qtdemux name=demux demux.a
udio_00 !  decodebin ! alsasink device=plughw:0,8 demux.video_00 ! decodebin2 !
ximagesink

After adding logs at various points in libdce and libdri2,  I was able to get this.

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Have X11
libdce-x11.c:64:        dce_auth_x11    info: attempting to open X11 connection
DRI2QueryExtension: eventBase=73, errorBase=0
DRI2QueryVersion: major=0, minor=0
_rep.driverNameLength = 0, rep.deviceNameLength = 0
libdce.c:448:   init    info: no X11/wayland, fallback to opening DRM device directly
libdce.c:460:   init    error: could not get plugin ioctl base: -22

I'm NOT using Ubuntu.   I'm building all the drivers, libraries and binaries using buildroot and the linux kernel version I'm using is 3.2.14.

I'm explictly running Xserver and I my attached my Xorg.0.log file.

5481.Xorg.0.log

I even followed the steps in the following link.

Does that mean Ducati plugins will only work on Ubuntu ?

I have updated all the packages and using the latest versions of them as of date.

    Hi,

    Can anyone please help me ?

    Or maybe suggest how exactly to proceed with getting these ducati plugins work.

    Do you suggest a different linux kernel version ? Because when I was looking into the scripts from ubuntu-omap4-extras-config, I saw it trying to load a few modules, "omap_rpmsg_resmgr rpmsg_resmgr_common omap_remoteproc omaprpc rpmsg_omx omapdce".

     So it is ducati support kernel specific ?

    Thanks in advance,

    Carol

    Carol,

    In order to use ducati codecs and SGX based video sinks on a non-debian based distribution, you need the following:

    * TI 3.4 kernel (see http://omappedia.org/wiki/Ubuntu_kernel_for_OMAP4 and http://dev.omapzoom.org/?p=integration/kernel-ubuntu.git;a=shortlog;h=refs/heads/ti-ubuntu-3.4-1489).

    * TI Ducati firmware, that can be extracted from ti-firmware-ipu-dce package of TI release PPA (https://launchpad.net/~tiomap-dev/+archive/release).

    * SGX user-space and kernel module, from pvr-* packages of TI release PPA.

    * TI user-space components from https://gitorious.org/gstreamer-omap

    * The startup script from ubuntu-omap4-extras-config, as you already noticed.

    Also, ximagesink is not HW accelerated. For better performance, use dri2videosink.
