vaapih264enc crashes with segfault.

Regarding vaapih264enc, as far as I checked with gst-inspect-1.0,

  • width : 1 ~ 2147483647
  • height : 1 ~ 2147483647
  • framerate : 0/1 ~ 2147483647/1

However, even within these ranges, GStreamer may crash with a segfault depending on the combination of resolution, frame rate, and bit rate.

The frequency of crashes has the following trends:

  • The smaller the resolution, the more likely it is to occur.
  • The lower the frame rate, the more likely it is to occur.
  • The higher the bit rate, the more likely it is to occur.

The following is an example of a combination that causes a crash.

  • Resolution : 320 x 320
  • Frame rate : 5 fps
  • Bitrate : 8 Mbps

Regarding the above symptoms, where should I review?
Regarding vaapih264enc, are there any restrictions on input data or setting values?

environment :

  • CPU : Atom-x5 E3930
  • Linux Kernel : 5.10.115-cip7
  • GStreamer : 1.20.5
