Memory leak when using OpenCL filters on specific environments

[rigaya]

There seems to be memory leak when using any OpenCL filters in specific environments, memory usage of QSVEnc continuously go up as time pass. Strangely, the problem seem to not apply to all systems.

• Tested with QSVEnc 7.46

• Example options QSVEncC64.exe -i input -o output --vpp-pmd apply_count=5

• systems confirmed to have memory leak

  • Win11 i9 12900K (ADL)
  • Win11 Arc A380 (DG2)

• systems confirmed to not have memory leak

  • Ubuntu 22.04 i3 N305 (ADL)
  • Win11 i5 1035G7 (ICL)
  • Win10 i5 7500 (KBL)

I’m currently not being able to find out the cause or ways to avoid this memory leak. It’s weird that the behavior differs between systems, even if I run the same option with same binary.

Does the error message look like this when it happens?

QSVEncC.exe finished with error!`

Because after restarting the encode it works. This happened after I test encoded around 200 files in batch mode.

No, actually there are no error message with the memory leak mentioned, it runs successfully, the only problem is the memory leak (memory usage of QSVEnc continuously goes up).

Seems to have been driver issue, no issue with QSVEnc 7.53 + 4953 driver on DG2.
