Closed zhoub closed 4 years ago

zhoub commented 4 years ago

Hi !

Our program needs to use VAAPI to keep decoding MJPEG file. According the experiment, the VA keeps leaking the small amount of memory until used the all memory and crash.

Tested with latest 2.4.0pre. The detailed info will be appended.

Thank you very much.

Today I formatted the disk and reinstalled a clean Ubuntu 16.04, built libva and intel-vaapi-driver, the strange things was that it doesn't appear anymore. I think it's related to some libraries in the system.
