Summary: Microsoft Powerpoint 2010: hangs up when seeking mp4
video
Product: Wine
Version: 3.0-rc4
Hardware: x86-64
OS: Linux
Status: UNCONFIRMED

Microsoft Powerpoint 2010 hangs up when seeking playing video.
I have tried to install MS Office 2010 on Wine 3.0-rc4, everything works like a
charm. I was able to embed and play mp4 videos (only mp4) with Powerpoint; but
when seeking, Powerpoint was suspended and could not return.
But when I completely remove the audio channel from the file by "ffmpeg -i
videoAndAudio.mp4 -c copy -an onlyVideo.mp4" command (only keep the video
channel) and insert again, this hangup error has disappearred.
So when I rebuilt from source to reproduce this error, I found that the bug
occurs at dlls/winegstreamer/gst_cbs.c:call_cb function, where wait for
condition pthread_cond_wait(&cbdata->cond, &cbdata->lock); and somewhere in
dlls/winegstreamer/gstdemux.c:dispatch_thread. May be there is a deadlock with
the synchronization of the audio and video channel.
OS: Kubuntu 17.04 zesty
MSOffice 2010 with no service pack
riched20 (natice, builtin)
msxml6 from winetricks (native, builtin)
libgstreamer1.0-0
libgstreamer-pligins-{bad,base,good}1.0-0
Give me feedback if you need more information.
Thanks & best regards
