[Libav-user] Memory doesn't decrease after freeing a derived device context of type AV_HWDEVICE_TYPE_QSV

[karim abd]

Thank you for your help
using your patches hwcontext_qsv works without any memory leaks
Best regards

Hi
Thank you for your help
I tried your code but  it doesn’t leak memory
My code leaks memory only when these 2 lines are used
                                err = av_hwdevice_ctx_create_derived(&encoderContext->hw_device_ctx, AV_HWDEVICE_TYPE_QSV, hardwareDeviceContext, 0);
                                err = av_hwframe_ctx_create_derived(&encoderContext->hw_frames_ctx, AV_PIX_FMT_QSV, encoderContext->hw_device_ctx, hardwareFrameContext, 0);
Best regards
