[vlc-devel] [RFC-PATCH 05/12] core: added EsOutDecodersSetPreroll to es_out.c

[Filip Roséen]

This function is used to propagate the preroll-end-timestamp "down" to
each of the decoders associated with an es-out. This patch includes
introduction of such usage within the block that handles
ES_OUT_SET_NEXT_DISPLAY_TIME.
