[Bug 789835] New: Video playback on some applications brings system to a halt

["GStreamer" (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=789835

Bug ID: 789835
Summary: Video playback on some applications brings system to a
halt
Classification: Platform
Product: GStreamer
Version: 1.12.3
OS: Linux
Status: NEW
Severity: critical
Priority: Normal
Component: gstreamer (core)
Assignee: gstreamer-***@lists.freedesktop.org
Reporter: ***@gmail.com
QA Contact: gstreamer-***@lists.freedesktop.org
GNOME version: ---

Previously filed a bug @ https://bugs.kde.org/show_bug.cgi?id=386284

After update to Kubuntu 17.10 video playback is buggy. On most video files
Gwenview brings the whole system to a halt, just leaves some seconds to
interact and kill the application to rescue the system or a warm reboot is
necessary.

This happens elsewhere as well e.g. previewing video in Dolphin. In contrast
VLC plays the videos smoothly and the system functions as usual. I guess some
updated backends are at fault.

Can you share more specific steps to reproduce this issue, such as sample
files, gstreamer version in use, and more critically some way to reproduce your
problem that does not involve an external application? For example, have you
tested playing back one of these files with "gst-launch-1.0 playbin
uri=file:///path/to/file"?

This is the output from playing the attached video sample. I had to ^C to send
signal since the system was in a state of trans: no key press worked, no click
captured, even the pointer froze intermittently for longer moments. If computer
got some time, it was killing and restarting plasmashell in a loop in that
window.

Sample video to show gstreamer computer lock down

This is a cut scene from the original intended sample. That exceeds the set
file size limit.

Thanks! It would still be helpful if you could share the exact version of
gstreamer and its plugins that you are using.

For what it's worth on my end with git master nothing gets decoded and I get a
lot of libav errors, with 1.12.3 it plays just fine, I do not get any sort of
lockups but I also am not using vaapi.

Could you try if you get the same problems with a manually constructed pipeline
such as:

gst-launch-1.0 uridecodebin uri=file:///path/to/media ! video/x-raw !
videoconvert ! xvimagesink

And assuming you have gst-libav installed:

gst-launch-1.0 filesrc location=/path/to/media ! qtdemux ! queue ! avdec_h264 !
videoconvert ! xvimagesink

Do the problems go away if you uninstall the gstreamer-vaapi package (and
install gst-libav/gst-ffmpeg instead?)

Just removed vaapi and all is OK. If required to troubleshoot gstreamer-vaapi,
I can reinstall and check results of Comment 4.

Well these comments were there to check whether vaapi was causing the issue, so
there's no need to now :)

Hm, seems like the same issue here
https://bugzilla.gnome.org/show_bug.cgi?id=775698

Ubunut17.10 + vaapisink will not work if you use default display server (which
is wayland in Ubuntu 17.10). Issue seems to be in "mutter".

This looks like a very different problem, like if the decoding or rendering is
messing with the system.

Could you reinstall gstreamer-vaapi and try:

1\ gst-play-1.0 How\ to\ add\ an\ employee\ in\ Loyverse\ POS\ \[720p\].mp4
--videosink=fakesink

Is the audio played correctly?

2\ gst-play-1.0 How\ to\ add\ an\ employee\ in\ Loyverse\ POS\ \[720p\].mp4
--gst-debug=vaapi*:5 > out.log 2>&1

please upload the generated file out.log

3\ please post the output of the vainfo command

1\ Audio played correctly till the end without video play but there was
glitches and after it reached the end I had to Ctrl-C. It finished naturally
though, perhaps did not catch the signal.

2\ Uploaded attachment 363183.

that log is quite strange. it is like all the frame were blocked until the
audio ends, as if they have a PTS in the future.

1\ Have you tried with a different video sink, such as glimagesink or
xvimagesink?

I don't see any error in the logs, perhaps the issue is somewhere else.

2\ Can I ask you for another log, the same pipeline with vaapisink, but *:5 (it
is going to be huge).

By the way, do you known which is the video sink used by Gwenview??

3\ Regarding driver mess up mentioned in comment 15, I once checked hardware
capabilities (3D rendering etc.) and followed some notes found on the Internet
to upgrade video drivers, but then rolled back the changes as far as I could.
More precisely it was about the OpenGL version supported on the system.

It's a bug which interferes with the system until it is unusable. That's
critical if not fixed. The code can propagate in downstream products and cause
undesirable main and side effects.
