kernel panic when pause video

[damien7851]

Hi,

If i play a HD video with mpv and pause it kernel panic.

I use libsunxivdpau from sunxi github.

[dan-and]

I need more details:

A) Which Kernel Version - Self made or one of my tar balls from http://dl.danand.de/ ?

B) Which version of Linux-Distribution, Player version, libsunxivdpau version ?

C) Do other videos work ? How to reproduce the error ?

D) Log output, log output, log output ;-)

Hi,

I have compiled from my fork of our kernel form github : Linux cubietruck 3.4.111-ir+ #8 SMP PREEMPT Fri Apr 22 22:52:46 CEST 2016 armv7l armv7l armv7l GNU/Linux

I use armbian trusty.

libvdpausunxi commit : 906c36ed45ceb53fecd5fc72e821c11849eeb1a3 form official

mpv 0.3.4 (C) 2000-2013 mpv/MPlayer/mplayer2 projects built on 2014-02-01T17:13:16 libav library versions: libavutil 52.3.0 libavcodec 54.35.0 libavformat 54.20.3 (runtime 54.20.4) libswscale 2.1.1 libavfilter 3.3.0 libavresample 1.0.1

mpv video conf :

##################

video settings

##################

Specify default video driver (see --vo=help for a list).

vo=vdpau hwdec=vdpau hwdec-codecs=all

Start in fullscreen mode by default.

fs=yes

brightness=10 contrast=0 gamma=1

force starting with centered window

geometry=50%:50%

don't allow a new window to have a size larger than 90% of the screen size

autofit-larger=90%x90%

Disable the On Screen Controller (OSC).

force-rgba-osd-rendering

Keep the player window on top of all other windows.

ontop=yes

all video with h264 fail on pause but play correctly.

for reproduce bug simply play video and put in pause !

It's possible that you need to recompile video drivers if you changed kernel. https://github.com/igorpecovnik/lib/blob/master/desktop.sh#L78

I never experienced crash while playing video with mpv. But my usage was only few test runs to check if building was done properly.

[damien7851]

Hello,

This bug has been present and before I recompile kernel(the 3.4.108 I think). I will nevertheless try to recompile the driver of any way it will be just as beneficial.

After I will try to apply it: http://forum.kodi.tv/showthread.php?tid=254202. I have to patch the kernel and add cma. And I intend to do the test starting from a headless xenial if possible otherwise a jessie.

But the main thing for me is to have a reliable solution playback HD video with sound in 5.1

[igorpecovnik]

This is not my field, don't know much but I think you will need some luck to make this work. Check forum http://forum.armbian.com/ ... there has been some similar attempts.

[damien7851]

Yes it is on, but nothing ventured, nothing gained! Thanks for your help.

[damien7851]

I have tested video playback with last xenial armbian. Pause is ok. But it is not danand kernel...
