ffmpeg | branch: master | Stefano Sabatini <stefasab at gmail.com> | Fri Jun 1 14:46:54 2012 +0200| [4d6a8a2bdb19c4380cc458759b7bd221942a028f] | committer: Stefano Sabatini
lavfi: add avfilter_default_filter_name()
The function is modelled after av_default_item_name(), and will print the
name of the instance filter if defined, otherwise the name of the filter.
This allows to show the instance name in the log, which is useful when
debugging complex filter graphs.
