Wenbin Chen efe2b63c89 doc/examples: Add qsv_transcode example
Add qsv_transcode example which shows how to use qsv to do hardware
accelerated transcoding, also show how to dynamically set encoding
parameters.

examples:
Normal usage:
qsv_transcode input.mp4 h264_qsv output.mp4 "g 60"

Dynamic setting usage:
qsv_transcode input.mp4 hevc_qsv output.mp4 "g 60 asyne_depth 1"
100 "g 120"
This command initializes codec with gop_size 60 and change it to
120 after 100 frames

FFmpeg examples README
----------------------

Both following use cases rely on pkg-config and make, thus make sure
that you have them installed and working on your system.


Method 1: build the installed examples in a generic read/write user directory

Copy to a read/write user directory and just use "make", it will link
to the libraries on your system, assuming the PKG_CONFIG_PATH is
correctly configured.

Method 2: build the examples in-tree

Assuming you are in the source FFmpeg checkout directory, you need to build
FFmpeg (no need to make install in any prefix). Then just run "make examples".
This will build the examples using the FFmpeg build system. You can clean those
examples using "make examplesclean"

If you want to try the dedicated Makefile examples (to emulate the first
method), go into doc/examples and run a command such as
PKG_CONFIG_PATH=pc-uninstalled make.
