System Info:
Processor: Intel Celeron 3955U @2.00 GHZ
Graphics Driver: Intel HD Graphics 510 (15.40.25.4463)
Operating System: Windows 7 - 64 bit
Intel Media SDK Version: 2016 - R2
Problem: A memory leak has been observed while using encoding (h264) frames with the the latest driver (15.40.25.4463) driver. The current beta driver also has the memory leak (15.40.26.4474)
I tried previously released drivers and can confirm that the 15.40.10.4300 driver does not have the memory leak. The memory leak seems be introduced in 15.40.22.4424 and still exist in newer drivers.
Steps to reproduce:
Encode a relatively input large file (> 30 GB) with the sample_encode.exe utility and observer memory usage in task manager:
sample_encode.exe h264 -i input.yuv -o output.264 -w 1920 -h 1080
Note: A large input file is used to prevent the sample_encode utility from ending quickly.
With 15.40.25.4463, the memory usage steadily increases. On the other hand, with 15.40.10.4300 memory usage is stable.
