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.

Restore the old name, which was more meaningful and consistent with the
names of the other examples.

Show how to perform streamcopy from one container to another.
|

|

|
|

That example shows how the decoding process works, not only the
demuxing.

There is no much point in optimizing example code, and the -O2 flag is
annoying when debugging.
|

|

|

|

This is more useful for testing purposes. Also allow to specify the name
of the output file.

In case CFLAGS/LDLIBS are already defined and conflicting with the
pkg-config flags, give priority to the latter since they are used to
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.
|
| |
|
|
|
|
| |
$(RM) already includes that flag.

This example should be useful to show the basic functionality of the
libswscale API.
More advanced features (scaling options etc., colorspace tweaking) may be
added later.
|

Use $(RM) in place of rm, drop useless "-r" for removing files.

Do not clutter the temporary directory with files, also "/tmp" is not
always available, e.g. in Windows.
Also add the clean-test Makefile rule, which will clean the generated
files.

The filtering_audio.c example needs to be updated for the new
"abuffer" filter args.

It is required for audio filtering.

Mostly based on doc/examples/filtering.c. lavfi API is still limited to
"buffer feeding" instead of "frame feeding" at the moment, so this
example code sticks with it.

The suffix is redundant since the containing directory itself is
called "examples". Simplify.
|

|

Rename:
api-example.c -> encoding-example.c
output-example.c -> muxing-example.c
