Parsed_filter_X could remain and user can override it with custom one.
Example:
ffplay -f lavfi "nullsrc=s=640x360,
sendcmd='1 drawtext@top reinit text=Hello; 2 drawtext@bottom reinit text=World',
drawtext@top=x=16:y=16:fontsize=20:fontcolor=Red:text='',
drawtext@bottom=x=16:y=340:fontsize=16:fontcolor=Blue:text=''"

this allow a filter to be written like this:
aformat =
sample_fmts = fltp|flt:
sample_rates = 44100|44800

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

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.

lavfi: add avfilter_init_str() to replace avfilter_init_filter().
avfilter_graph_create_filter() opaque is still passed to avfilter_init_filter()
which continues to pass it to init_opaque as its still used in the buffer sinks
the sinks should be changed and the opaque passing removed

Since we do not support "standalone" filters not attached to an
AVFilterGraph, we should not have a public function to create such
filters. In addition that function is horribly named, the action it does
cannot be possibly described as "opening" a filter.
