This tool uses lavfi internal symbols not accessible in shared
libraries. TESTPROGS are linked statically to allow them use of
library internals not normally exported.

Inspired by MPlayer's af_channels filter and SoX's remix effect.
|
|
|
|
| |
It joins multiple input streams into one multi-channel output.
|
| |
|
|
|
|
| |
It will be used for audio too.

avfilter_config_links()
Link properties have to be checked after config_props() is called to
make sure everything is sane, so the default config_props() for output
links was redundant.
Remove now empty defaults.c

Based on current version of the asplit filter in FFmpeg written by
Stefano Sabatini and others.

This is in preparation for adding an audio split filter.

This is easier to follow than having them randomly scattered in
avfilter.c and defaults.c.

The scale filter is used for internal colorspace conversions, so it must
always be present.

This allows simplifying the Makefiles; it is no longer necessary to register
arch subdirectory Makefiles, just putting them in place is enough.

It can be used to directly pass a AVFilterBufferRef to lavfi, avoiding a
memcpy.

|
|
|
| |
It's a part of public API.

Declaring tools associated with each library in their respective
makefiles allows these tools to easily depend on the correct
prerequisites and link against the libs they need.

Calling Make from subdirectories is not supported and config.mak has
multiple inclusion guards anyway, so the top-level include is enough.

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.
