Noob here. I would like to suggest a simple change to libavutil\timestamp.h,
that for me makes the difference between silencedetect being very useful, or
not useful at all. If there is a better way to submit this, I'm happy to jump
through proper hoops... this seems like a good place to start t
Keyframes are signaled at the container level on Matroska/Webm files,
so bitstream parsing for that purpose is unnecessary.
Should speed up demuxing a bit.

Add support for GPU copy when QSV decoders works in system memory mode.
However, memory must be sequent and aligned with 128x64 to enable this
feature.(first introduced in FFmpeg 3.3.1)
GPUCopy = MFX_GPUCOPY_ON leads to performance improvement up to x10.
CMD:
ffmpeg -init_hw_device qsv=hw -filter
Copy from video to system memory, so output in sysmem memory mode is needed.

Previously discussed in:

This mode is needed in gpu_copy, is this feature implemented in
current lavc now?

Usage is:

What is it? Is it part of the driver? Is it installed at the same time as the
driver?

Yes, it's part of the installation for the driver of the card. People
