From b782c901809a47dddadc33368d66d88d1bd9e9b9 Mon Sep 17 00:00:00 2001 From: wm4 Date: Sun, 10 Dec 2017 05:07:36 +0100 Subject: demux_timeline: disable pointless packet cache for sub-demuxers It seems like there's nothing stopping from sub-demuxers from keeping packets in the cache, even if it's completely pointless. The top-most demuxer (demux_timeline) already takes care of caching, so sub-demuxers only waste space and time with this. Add a function that can disable the packet cache even at runtime and after packets are read. (It's not clear whether it really can happen that packets are read before demux_timeline gets the sub-demuxers, but there's no reason to make it too fragile.) Call it on all sub-demuxers. For this to work, it seems we have to move the code for setting the seekable_cache flag to before demux_timeline is potentially initialized, because otherwise the cache would be reenabled if the demuxer triggering timeline support is a timeline segment itself (e.g. ordered chapters). --- demux/demux.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'demux/demux.h') diff --git a/demux/demux.h b/demux/demux.h index 9224ca3a98..aeabd36e99 100644 --- a/demux/demux.h +++ b/demux/demux.h @@ -298,6 +298,8 @@ int demux_stream_control(demuxer_t *demuxer, int ctrl, void *arg); void demux_changed(demuxer_t *demuxer, int events); void demux_update(demuxer_t *demuxer); +void demux_disable_cache(demuxer_t *demuxer); + struct sh_stream *demuxer_stream_by_demuxer_id(struct demuxer *d, enum stream_type t, int id); -- cgit v1.2.3
