start_frame is no more, samplesref argument is now frame argument.

Signed-off-by: Paul B Mahol <onemda@gmail.com>

Instead of calling the input filter request_frame() method,
ff_request_frame() now marks the link and returns immediately.
buffersink is changed to activate the marked filters until
a frame is obtained.

The status field can carry any error code instead of just EOF.
Also only update it through a wrapper function and provide a timestamp.
Update the few filters that used it directly.

Applications are not supposed to mess with links,
they should close the sinks.
Furthermore, this function does not distinguish what end
of the link caused the close and does not have a timestamp.

This field is used for fast comparison between link ages,
it is in AV_TIME_BASE units, in other words microseconds,
µs =~ us.
Renaming it allows a second field in link time base units.

It requires a loop in filters or the framework,
that makes the scheduling less efficient and more complex.
This is purely an internal change since the loop is now
present in buffersink.
Note that no filter except buffersink did rely on the requirement.

This API hasn't been active since the last bump already.

Define positive return values as non errors and leave further meaning undefined
This allows future extensions to use these values

This function should never modify the filter.

Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Add function avfilter_graph_parse_ptr() and favor it in place of
avfilter_graph_parse(), which will be restored with the old/Libav
signature at the next bump.

If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the
Libav-compatible signature for avfilter_graph_parse().

At the next major bump the current implementation of
avfilter_graph_parse() should be dropped in favor of the Libav/old
implementation.

Should address trac ticket #2672.

Mostly based on libavcodec's

With the introduction of AVFilterContext->is_disabled, we can simplify
the custom passthrough mode in filters.

This commit is technically a small compat break, but the timeline was
introduced very recently.

Flag added in a few simple filters. A bunch of other filters can likely
use the feature as well.

This is mostly automated global search and replace

The deprecated aconvert filter is disabled, if it still has users
it should be updated

Removes an arbitrary hardcoded limit on the number of filters.

The caller needs to know what valid indices can be passed to
avfilter_pad_get_name/type.

This will be useful in avtools in the following commits.
Any other caller might also want to know this information.

Drop the unused opaque parameter from its signature.
