Bug#977286: crash on H.264 encoding
Package: intel-media-va-driver-non-free
Version: 20.4.2+ds1-1
Severity: important
Tags: patch upstream
Hi,
Whenever I start Nageru on my Kaby Lake laptop, it segfaults in the VA driver.
This was fine in 20.3.0+ds1-1, broke in 20.4.1+ds1-1, and is still the case
in 20.4.2+ds1-1. However, compiling upstream 20.4.3 appears to fix it.
This is the relevant patch according to bisect:

[Media Common] Integrate new gmm API for external surface
Integrate new gmm API to create gmmResInfo for external surface.
Need to update gmm to intel-gmmlib-20.3.3.
This is the backtrace:
Thread 15 "QS_Encode" received signal SIGSEGV, Segmentation fault.

Please upgrade to 20.4.3, and the crash should go away.
