#7901 new defect

Green/null frames at beginning of decoding with qsv decoders

Description

Summary of the bug: When using h264_qsv,hevc_qsv or mpeg2_qsv(haven't tested mjpeg_qsv) decoders sometimes when the decoding starts 1-3 green/null(I'm not sure if they are green or null, ffplay shows them as green in the render) frames appear in the beginning (mostly in between 1-10 frames of the beginning file).

I've managed to test almost all the mainstream Intel iGPU's - 3rd gen(i7-3770,HD 4000), 4th gen(i7-4770 & i5-4570,HD 4600), 6th gen(i7-6700k,HD 530), 8th(i7-8700k,UHD 630) and 9th gen(i9-9900k,UHD 630) with latest graphics drivers on Windows.

The frequency at which it appears isn't constant, i.e. in 10 tries 1-5 of them will be affected.

The test file for h264 which I'm using is this one http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_1080p_30fps_normal.mp4

I can attach more test files if required.

But I don't think it has something to do with the specified file.

This particular log is from a machine with a 4th gen graphics and Windows 10. Tested with latest(as of today) Zeranoe git build.
