◆ input_DecoderHasFormatChanged()

bool input_DecoderHasFormatChanged	(	decoder_t *	p_dec,
		es_format_t *	p_fmt,
		vlc_meta_t **	pp_meta

This function will return true if the ES format or meta data have changed since the last call.

In which case, it will do a copy of the current es_format_t if p_fmt is not NULL and will do a copy of the current description if pp_meta is non NULL. The es_format_t MUST be freed by es_format_Clean and *pp_meta MUST be freed by vlc_meta_Delete. Otherwise it will return false and will not initialize p_fmt and *pp_meta.
