OpenEmbedded/Yocto for UDOO Boards

Hi graugans, i used the first. Otherwise for the gstreamer libs, now with PACKAGECONFIG_append_pn-qtmultimedia = " gstreamer010" i have this in usr/lib/qt5/plugins/mediaservice/

libgstaudiodecoder.so libgstcamerabin.so libgstmediacapture.so libgstmediaplayer.so

I didn't have the time to test it but i think i will can during this week end.

I'm agree with you about the version of gstreamer, but i didn't find an example that use v1.0 !

get an eye on this layer please and let us know : https://github.com/dv1/meta-gstreamer1.0/blob/master/README.md

 

I did this and it's compil. Now i need to compare that's work ! i let you know ...

 

test with gstreamer 0.1

Error: "Your GStreamer installation is missing a plug-in."

 

No problem, i will do it !

 

Graugans, with

PACKAGECONFIG_append_pn-qtmultimedia = " gstreamer"

play video works fine (1080 and 720p .mkv --> on quad, not tested on neo for the moment) I have just a warning about the audio (don't test it for the moment ) :



Warning: "No decoder available for type 'audio/mpeg, mpegversion=(int)4, framed=(boolean)true, stream-format=(string)raw, level=(string)4, base-profile=(string)lc, profile=(string)lc, codec_data=(buffer)11b0, rate=(int)48000, channels=(int)6, channel-mask=(bitmask)0x0000000000000000'."

perhaps need to add pulse audio to packageconfig ?! about audio, do you know if the song is drive to the analog or hdmi output by default ?

If you would to test video with qt, use the exemple qmlvideofx give by qt binaries (on your host pc).

I made another test, the cam. works fine with v4l driver :

gst-launch-1.0 imxv4l2videosrc ! imxipuvideosink

But not working with the qmlvideofx exemple --> i will make another tests this week

Another point, Qt quickcontrol (and extra) works now

 

Hi graugans, my udooqdl image build (folder where is the image) is growing to fast for my disk How i can clean it properly please ?

 

Thanks. i tested my image with pulse audio but no amelioration (same error) ...

PACKAGECONFIG_append_pn-qtbase = " accessibility pulseaudio"

Otherwise, for the touch screen i added this (qt need it) to IMAGE_INSTALL_append :

tslib \
tslib-conf \
tslib-tests \
tslib-calibrate \

not working for the moment (see this link http://www.lindusembedded.com/blog/2013/02/07/adding-touch-support-in-yocto/) result of dmesg :

input: st1232-touchscreen as /devices/soc0/soc.0/2100000.aips-bus/21a8000.i2c/i2c-2/2-0055/input/input0

i think, ineed to disable it in the kernel (in defconfig) , to have usb touch ?

#Touch
CONFIG_TOUCHSCREEN_ST1232=n

Otherwise, i make a test with qt for blue tooth (it didn't work, but work with hcitool). Qt need bluez to enable bluetooth. I saw that on meta freescal they have a module meta-fsl-bluez, can you advise me how to include it to the Qt image please ?

 

If i can choose a prio i prefer audio and bluetooth

 

No problem

 

Hi,

I compile the core-image-full-commandline for Udoo Quad and the compilation go OK.
On my Udoo, I can boot but I have issue with HDMI on linux ( Uboot ok, I can see the Udoo logo ). No video on the screen.
I have a 1920 x 1080 monitor and linux fbv report 1920x1080@30.
How can fix this issue?
I tried the wifi adapter in manage mode and issues with iwconfig.
How can connect to a SSID?

 

Hi did you have some warning during compilations ? I don't use this image (qt5 image) but i didn't have this problems ... Probably Graugans can help you more ...
