Which component impacted?

Decode

Is it regression? Good in old configuration?

No, this issue exist a long time

What happened?

  1. System requirement: Windows FFmpeg version 4.4, which enabled qsv_h264 decoder, use libmfx (version1.25) as frontend.

  2. Reproduce step:
    I use FFmpeg libs in my video conference application. That is running as client app on Windows 10 system. Client APP receive 9 video streams(differenct video resolution) simutanously, which decoded by qsv_h264 decoder.

  3. Errors: MFXVideoDECODE_DecodeFrameAsync always returns MFX_WRN_DEVICE_BUSY, that cause dead loop.
