No errors in dmesg. In htop I saw a 99% IOwait on one CPU core. Vlc was killed by "-9" and no side-effects on overall system I can observe. This behaviour is not on all video files. So. It looks like some video file (and youtube stream) has some frames that HW decoder can't understand and it is a fatal for HW decoder. Or decoder generate some error code that libva can't parse? At this stage I can't understand which component is broken.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
