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

Fri Jan 30 04:35:21 PST 2015

Thanks for the answer Carlos.

At the end what I did was to remove the
PACKAGECONFIG_append_pn-qtmultimedia = " gstreamer010 "
On my local.conf file.
Qtmultimedia now compiled without problems. (I still have to see if it works)
I think the problem on the original qtmultimedia.inc dizzy recipe is that if I configure to use gstreamer 0.1 then the recipe still patches qtmultimedia with a 1.0 gstreamer patch.

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:

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?

Better don't. The current .inc file looks quite different. You might inadvertently replace new code with old one if you do this.

I'd rather try to copy & paste the do_configure_prepend() block into the existing qtmultimedia.inc (unless that block makes no sense anymore). Also, "gstreamer1.0" should be added to the DEPENDS list unless GStreamer 0.10 is built. So, perhaps the gstreamer010 packageconfig line line should be replaced by this:

DEPENDS += "${@bb.utils.contains('PACKAGECONFIG', 'gstreamer010', 'gstreamer gst-plugins-base', 'gstreamer1.0 gstreamer1.0-plugins-base', d)}

Also, note that I use bb.utils.contains instead of base_contains. The latter is preferred, and keeps Otavio happy ;)
