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

Anton Khirnov 15546f772c examples/avio_dir_cmd: drop support for move/delete operations
They use non-public functions, which is unacceptable for a public API
example. Rename the example back to avio_list_dir.

This effectively reverts c84d208c27 and
767d780ec0.

Jun Zhao 0519e66a90 examples: Add a VA-API transcode example.
Usage is:
./vaapi_transcode input_stream codec output_stream
For example:
- ./vaapi_transcode input.mp4 h264_vaapi output_h264.mp4
- ./vaapi_transcode input.mp4 vp8_vaapi output_vp8.ivf

Does not handle resolution changes on the input stream.

  build: Split logic for building examples off into a separate Makefile

We already have a Makefile in doc/examples, but it's separate from the build
system and meant to be installed as part of the documentation to help users
compile the installed .c example files.

Clément Bœsch b0352b1997 avcodec: export motion vectors in frame side data on demand
The reasoning behind this addition is that various third party
applications are interested in getting some motion information out of a
video "for free" when it is available.

It was considered to export other information as well (such as the intra
information about the block, or the quantization) but the structure
might have ended up into a half full-generic, half full of codec
specific cruft. If more information is necessary, it should either be
added in the "flags" field of the AVMotionVector structure, or in
another side-data.

This commit also includes an example exporting them in a CSV stream.

Stefano Sabatini e53becc70f examples/Makefile: give priority to pkg-config flags
In case CFLAGS/LDLIBS are already defined and conflicting with the

detect compilation flags.

This should fix for example the case where there are many different
instances of a library, CFLAGS=-I/foo/include and pkg-config cflags say
-I/bar/include.
