Hello Everybody,
My cpu is "Intel® Celeron® Processor J1800".
We use vaapi to do decode and display and set option "tearfree" "true" in xorg.conf, this is work well, but when we try to adjust system time reverse, the x window image freeze, only mouse can be moved. If we disable tearfree option, the system time can be adjust reverse well. It seems have some relation ship in the graphic hw work. How can I resolve this problem? Or have any other tearfree function can be replaced? I also try option "TripleBuffer" and "swapbufferwait" in xorg.conf, but still see the tear effect. Any suggest or response will appreciate.
our vaapi information like below:
