When I
rm -rf .cache/gstreamer-1.0/
kill mediascanner-server(mediascanner-server will restart)
the logcat output:

Can you please tell me the workflow about decoding or related ?
Any help will be wellcome :)

No usr.bin.media-hub-server file and media-hub-server on my touch system.
I am using the touch system is released at 4.17, and The same system is normal on my Nexus4.
apparmor is a must have ? It is disable in my kernel.



If apparmor is truly not running on your system, then you're fine. I just want to make sure we are getting all of the media-hub-server output possible in logcat.
 
The attachment is a complete log:system boot and play a video(open a video file by file manager)

Hi all,
I have puted Ubuntu Touch 14.04 port to a Android device，and it already can play audio.
But I have a problem when play video : video only display black but with audio works fine.
The video file can be played normally by use SurfaceFlinger and "codec -p" (codec is a tool in libhybris).
When I play video by use mir and mediaplayer-app, the log is very simple,only the following lines:


V/SurfaceTextureClientHybris( 4230): void* surface_texture_client_create_by_id(unsigned int) 
V/SurfaceTextureClientHybris( 4230): _SurfaceTextureClientHybris::_SurfaceTextureClientHybris() 
D/SurfaceTextureClientHybris( 4230): stch: 0x1f301f0 (void* surface_texture_client_create_by_id(unsigned int))
V/SurfaceTextureClientHybris( 4230): void set_surface(_SurfaceTextureClientHybris*, const android::sp<android::SurfaceTexture>&) 
V/SurfaceTextureClientHybris( 4230): void set_surface(_SurfaceTextureClientHybris*, const android::sp<android::SurfaceTexture>&) 
V/SurfaceTextureClientHybris( 4230): void surface_texture_client_set_hardware_rendering(SurfaceTextureClientHybris, uint8_t) 




Can you try again but this time do the following and reply back with the logcat output attached:


adb shell
sudo apparmor_parser -R /etc/apparmor.d/usr.bin.media-hub-server

restart media-hub-server
/system/bin/logcat
 


I think the android video decoding library not be call. so,I want to know  what is the workflow of touch 14.04 play video(use mir),and how can I debug it ?


This is how we can start to debug it. I really need to see the output of logcat to be able to first start to determine what the issue might be.
 
Any help will be wellcome :)
