Which type of video? (I mean which format video and audio codec)?
Would it be possible you attach or put it available somewhere?

It will happen with any media file, but i was using the avi file found at ( https://wiki.documentfoundation.org/Media_Support/Test_Media ).

@Qubit: did this happen to you when you were testing on Ubuntu?

On pc Debian x86-64 with master sources updated today, I could reproduce this.

I noticed these console logs:
warn:sd.core:23142:1:sd/source/core/PageListWatcher.cxx:95: ImpPageListWatcher::GetSdPage(PK_STANDARD): page number 1 >= 1
warn:avmedia:23142:1:avmedia/source/viewer/mediawindow_impl.cxx:277: failed to create media player service com.sun.star.comp.avmedia.Manager_VLC

Michael: thought you might be interested in this one since it concerns including video.

In fact, it fails with com.sun.star.comp.avmedia.Manager_VLC but it succeeds with com.sun.star.comp.avmedia.Manager_GStreamer

So I've kept on with gdb + ctrl-C at random and, seeing the bts, I wonder if it could be due to idle/timer last changes.

I believe bug 90077 (simply enabling the media playback toolbar) may also be effected by this issue.

No crashes for me with the test media when I did my initial tests. What's the specific file url?

It crashes with any of the test files in master. Also noticed the wiki link to the owncloud of the test files doesnt work. :D

Weird. I'll grab a master build and try it myself.

Uggh. Yeah, our ownCloud integration keeps on getting broken. I'll poke infra to fix that straightaway.

TESTING on Ubuntu 14.04 with LibreOffice master (daily):

REPRO Steps:
1) Open Impress
2) Insert -> Media -> Audio or Video 
  (dialog opens up)
3) I selected and inserted big_buck_bunny_480p_stereo_avidemux_30sec.avi from the set of test media (https://wiki.documentfoundation.org/Media_Support/Test_Media#Generated_Audio_and_Video)

RESULT: LibreOffice hangs 

----

Testing on the same machine, but with LO 4.2.6.3:
1) Open Impress
2) Insert -> Movie and Sound
  (dialog opens up)
3) I selected and inserted big_buck_bunny_480p_stereo_avidemux_30sec.avi from the set of test media (https://wiki.documentfoundation.org/Media_Support/Test_Media#Generated_Audio_and_Video)

RESULT: No hang/no crash

Keywords -> regression
Whiteboard -> bibisectRequest

This started on the same date as bug 90077, which is to say
  2015-03-07: source-hash-333f8a76341f5b4921e89012d133007503e49612
in the 4.5 dbgutil bibisect tree - and I think that is going to turn out to be the more relevant report. Most likely inserting a video hangs too because that automatically selects the inserted object, which in turn shows the media toolbar

Tobias - potentially linked to the idle/timer work =)

Bisected to the same range as bug 90077 - see bug 90077 comment 3

mp3 crashes LO too.

Its fixed now that bug 90077 has been fixed.
