Provide a way to wrap around the segment index so pseudostreaming
live through a web server and html5 browser is simpler.

Also ensure that 0 (disable) is a valid value across the options
providing wrap around.

r_frame_rate should in theory have something to do with input framerate,
but in practice it is often made up from thin air by lavf. So unless we
are targeting a constant output framerate, it's better to just use input
stream timebase.

Brings back dropped frames in nuv and cscd tests introduced in

Useful to return instead of -1 when the cause of the error is unknown,
typically from an external library.

The latter syntax is now invalid.

This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

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.

This will allow parsers to export the duration of the current frame being
output, if known, instead of using AVCodecContext.frame_size.

The channel layout must start with 0x, otherwise it is parsed as a
number of channels.

Keep the old protocol name around for backwards compatibility
until the next bump.

Deprecate the method of implicitly assuming the nested protocol.
For applehttp://server/path, it might have felt logical, but
supporting hls://server/path isn't quite as intuitive. Therefore
only support hls+http://server/path from now on.

Using this protocol at all is discouraged, since the hls demuxer
is more complete and fits into the architecture better. There
have been cases where the protocol implementation worked better
than the demuxer, but this should no longer be the case.

Mostly useful for debugging purposes.

This makes it possible to dintinguish them from PAL8.

Fixes an invalid write in avpicture_layout().

Deprecate avcodec_encode_video().

Most of the documentation is common to both filters, and I'm going to add
more shared docs. Factorize.

Factorize code and provide ratio parsing consistency.

Before, drawtext filter deliberately altered given text coordinates if
text didn't fully fit on the picture. This breaks the use case of
scrolling large text, e.g. movie closing credits.
Add 'fix_bounds', to make it usable in such cases (by setting its value to 0).
Default behavior is not changed, and non-fitting text coords are fixed.

This commit also drops the planar parameter; you now need to use the 'p'
suffix in order to request a planar sample format.
