hello nxp：

I use fsl-yocto-L4.9.11_1.0.0 on ubuntu1404

sources/meta-qt5/recipes-qt/qt5/qtmultimedia_git.bb have add  gstreamer

PACKAGECONFIG ??= "${@bb.utils.contains('DISTRO_FEATURES', 'alsa', 'alsa', '', d)} \
-                   ${@bb.utils.contains('DISTRO_FEATURES', 'pulseaudio', 'pulseaudio', '', d)}"
+                   ${@bb.utils.contains('DISTRO_FEATURES', 'pulseaudio', 'pulseaudio', '', d)} \
+       gstreamer"

yocto qt is qt5.8

by bitbake -c populate_sdk meta-toolchain-qt5

bitbake fsl-image-qt5

I get the rootfs and toochain

on the arm:

#:  gst-play-1.0 video_1080p_60fps.mp4

play ok

log:

loop play video is ok

 

but have errer when use qt5.8  qtmultimedia/examples/multimedia/video/qmlvideo

use qmlvideo  play mp4  use fillemode or fullscreen an so on ; play loop 3~5

,play stop by ctrl+c can exit app qmlvideo ;but touch button "back"

qmlvideo app will be break ctrl+c can not exit.

above all test ;the problem still is exist .

I have see the follow patchs

https://community.nxp.com/thread/530284

https://codereview.qt-project.org/c/qt/qtmultimedia/+/273602

I have patch am 273602 on qt5.8 qtmultimedia ;but the patch is invalid ,

on yocto fsl-yocto-L4.9.11_1.0.0  use imx-gst1.0-plugin  can use gpu vpu and so on;

patch 273602 is gstreamer_imxcommon  ;   gstreamer1.0-plugins-imx  have imxcommon libs , but enable  gstreamer1.0-plugins-imx on yocto fsl-yocto-L4.9.11_1.0.0 will diable   imx-gst1.0-plugin can not use imx6q vpu gpu ;

proble will be still exist.

 

 

my debug log:

修改后rm config.cache 重新配置编译

编译后qmlvideo无法使用硬件加速
2、只修改qt源码qtmultimedia后 硬件加速正常，
 
qmlvideo播放还是会出现问题待继续测试 。，不会qt卡死
