[meta-freescale] qt5 qtmultimedia gstreamer1.0 on i.mx6 with Dizzy branch

[Mario Rodriguez]

Hello everyone,

I recently got the dizzy branch and tried to do an image (fs-image-multimedia-full). I added the qt5-meta layer. What I saw was the following error while compiling qtmultimedia:
| /opt/yocto-freescale/mx6sabrelite/tmp/work/cortexa9hf-vfp-neon-poky-linux-gnueabi/qtmultimedia/5.3.2-r0/qtmultimedia-opensource-src-5.3.2/src/gsttools/gstvideoconnector.c:467:32: error: 'GST_PAD_PROBE_DROP' undeclared (first use in this function)

I looks like the qtmultimedia tries to use gstreamer1.0 but it shouldn't
I have on my local.conf file
PACKAGECONFIG_append_pn-qtmultimedia = " gstreamer010 "
What I did in the end was following the instructions on this page:

Adding gstreamer1.0 support break qtmultimedia recipe. If you don't use gstreamer1.0 you must replace your meta-qt5/recipes-qt/qt5/qtmultimedia.inc by this code (and rebuild)



require qt5.inc



DEPENDS += "qtdeclarative alsa-lib"



PACKAGECONFIG ??= ""

PACKAGECONFIG[openal] = ",,openal-soft"

PACKAGECONFIG[gstreamer010] = ",,gstreamer gst-plugins-base"



do_configure_prepend() {

# disable openal test if it isn't enabled by PACKAGECONFIG

sed -i 's/^qtCompileTest(openal)/OE_OPENAL_ENABLED:qtCompileTest(openal)/g' ${S}/qtmultimedia.pro

# disable gstreamer-0.10 test if it isn't enabled by PACKAGECONFIG

sed -i 's/^\( *\)qtCompileTest(gstreamer) {/\1OE_GSTREAMER010_ENABLED:qtCompileTest(gstreamer) {/g' ${S}/qtmultimedia.pro

}



EXTRA_QMAKEVARS_PRE += "${@base_contains('PACKAGECONFIG', 'openal', 'CONFIG+=OE_OPENAL_ENABLED', '', d)}"

EXTRA_QMAKEVARS_PRE += "${@base_contains('PACKAGECONFIG', 'gstreamer010', 'CONFIG+=OE_GSTREAMER010_ENABLED', '', d)}"

Is that "the right" thing to do? Or this will cause me some problems later?
