Hello, am using current git version master branch. I observed since quite some while that seeking within movies causes kodi quite often to crash to desktop. This happens for h.264 movies on local harddrive but even more often on mpeg4 clips, common on internet.

i have here the debug log with extra debugging for ffmpeg and some other components and the crash dump.

Hope this helps. If you need something else just ask.

Here is my google drive directory with the crash dump and debug log file. Couldn't upload them to pastebin or similar due to their filesize
logs

try without oibaf ppa.

[a_user]

same. i installed oibafs to see if it fixes this. problem happens on stock ubuntu 13.10, stock ubuntu 14.10 and with oibaf.

this started (i think so) since about a week more or less. and it is very annoying as in around 50% times trying to seek within a movie kodi crashes to desktop.

simply playing them causes no issues.

edit2: it seems to not happen on some flv streams. so i think it is only related to severa codecs.

[fritsch]

Capture it in gdb, please.

[a_user]

do i need any additional libs for debugging?

edit: can't as it says no debugging symbols found. trying to rebuild it with symbols. if you have an hint how to do it the easiest way don't hesitat to tell me.

[a_user]

here you go. it stops here:

Code:

Program received signal SIGSEGV, Segmentation fault.

3043      if(outPic.frame->pkt_pts != AV_NOPTS_VALUE)

---

on a second try at first it didn't crashed when seeking, so i continued seeking forward multiple times and sometimes backward until it crashed.

here the result in gdb:

Code:

seems to have multiple reasons.

and a third one, this time i reverted oibaf ppa. it seems to be the same case as the last one (second try):

[wsnipex]

which libva1 and i965-va-driver do you have?

can you try the trusty one from https://launchpad.net/~wsnipex/+archive/ubuntu/vaapi
you'll probably have to rebuilt them for utopic

[a_user]

i don't understand your question. What exactly do you mean by "which"? version?

---

ok, i installed your ppa, chenged it from utpoic to trusty so it can upgrade to your libs and it crashed as usually again:

[fritsch]

Code:

thread apply all bt

we need and always the corresponding xbmc.log in debug form

[a_user]

i already attached that to the first post.

but i redo a gdb and attach the new log file during that run also here.

---

here link to google drive directory containing the gdb output you desired + the full debug log from kodi itself:

[FernetMenta]

please try my git master branch, it's always a couple of patches ahead of mainline. for example I have not merged this one which may be the cause of this segfaults: https://github.com/FernetMenta/xbmc/comm...7c6a9a5a9d

[a_user]

is this the url to clone?
https://github.com/FernetMenta/xbmc.git

[fritsch]

Yes - master branch.

[a_user]

ok. i am currently cloning. will build and test and report later back.
