memory leak on CentOS for video transcoding sample

Hi,

We found memory leak when using Intel® Media Server Studio 2017 R2 for Linux on Intel(R) Xeon(R) CPU E3-1515M v5 @ 2.80GHz
CentOS Linux release 7.2.1511 (Core)
00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:193d] (rev 09)
vainfo: VA-API version: 0.99 (libva 1.67.0.pre1)
vainfo: Driver version: 16.5.55964-ubit

we use Video Processing (VPP) Sample sample_vpp to transcode 40 streams and there is memory leak ~384k/min.

 

Thanks,

Jason

Hi all,

  Sorry. We need more tests to verify it because after several hours the memory usage increased from 1.51G to 2.71G​ and stop increasing.

We changed the source code. We added a loop.

Thanks,

Jason
