I am running into a problems with video files with LC-AAC audio. Some of them play smoothly, some of them crash XBMC.
I tested thoroughly on one file and found following regularities:
- if VAAPI is enabled crash happen on same place of file, without VAAPI crash happens elsewhere
- XBMC lasts longer without VAAPI, sometimes it is able to stay alive three times longer than with VAAPI
- If I fastforward to known crash place with VAAPI enabled then crash dont happen, so most likely it is playback time, not exact data which cause crash
- in both cases messages like during playback.
- sometimes dmesg contains segfault log entry, sometimes not. Sample dmesg message is:
crashlogs with debug output:
-no VAAPI: http://pastebin.com/dvgzYKsU
-VAAPI: http://pastebin.com/VM5njvYa
XBMC is latest nightly build from PPA.
