The cpia video decoder is intended to be used with the v4l2 demuxer.
There are some small changes to the v4l2 demuxer to support the
variable frame length of the format.
Fixes ticket #1537

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.

This patch accepts 'timeout' option for input mode only. As far as i know, UDP output cannot introduce delays.

$(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.

Extract of the output:

| Individual channels:
| NAME        DESCRIPTION
| FL          front left
| FR          front right
| <snip>
| SDR         surround direct right
|
| Standard channel layouts:
| NAME        DECOMPOSITION
| mono        FC
| stereo      FL+FR
| <snip>
| octagonal   FL+FR+FC+BL+BR+BC+SL+SR
| downmix     DL+DR

Add a switch which controls which operation to perform.  Useful to test
only a single feature. Also the new behavior is more self-consistent.

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.

Since audio and video filters are explained together and share most code,
the multimedia filters section seems more fitting.

Also fill in missing dates and hashes.

Put the relevant code in one chunk, also check for frame allocation
failures.

Also provide a link to the github FFmpeg page containing the examples.

Fix warnings:
muxing.c: In function ‘write_video_frame’:
muxing.c:326:23: warning: passing argument 2 of ‘sws_scale’ from incompatible pointer type [enabled by default]

Fix trac ticket #1665.

This option does not do anything.

Also remove OPT_GRAB, since -isync is the last option using it.

The simplifications are due to the recent option changes.

This is technically a major compatibility break, but seems the most
natural default and what users would expect without reading the docs.

An equivalent framestep filter has been natively integrated.

This filter is inspired upon libmpcodecs/vf_framestep.c, by Daniele
Forghieri.

Only-keyframe output is not supported, since that feature can be achieved
through the more versatile select filter.

Address trac ticket #1642.

Consistent with --enable-doc, and easier to type.

Make it print a list of AVCodecDescriptors.

Add new -decoders and -encoders options that print lists of decoders and
encoders respectively.

Add files created for MP3 optimization that have MIPS copyright
 notice in them to list of files in mips.txt.
