From abc33c928fc39ab58ec7f8f3784b72b4266242ae Mon Sep 17 00:00:00 2001 From: Oleksij Rempel Date: Thu, 9 Jul 2015 09:51:26 +0200 Subject: [PATCH] vp8enc: provide support for multiple pass cache files Some files may provide different caps insight of one stream. Since vp8enc support caps reinit, we should support cache reinit too. If more then file cache file will be created, the naming will be: cache cache.1 cache.2 ... https://bugzilla.gnome.org/show_bug.cgi?id=747728 --- ext/vpx/gstvp8enc.c | 51 ++++++++++++++++++++++++++++++++++++--------------- ext/vpx/gstvp8enc.h | 2 ++ 2 files changed, 38 insertions(+), 15 deletions(-) diff --git a/ext/vpx/gstvp8enc.c b/ext/vpx/gstvp8enc.c index 364bfa3..f203cdc 100644 --- a/ext/vpx/gstvp8enc.c +++ b/ext/vpx/gstvp8enc.c @@ -557,7 +557,9 @@ gst_vp8_enc_class_init (GstVP8EncClass * klass) g_object_class_install_property (gobject_class, PROP_MULTIPASS_CACHE_FILE, g_param_spec_string ("multipass-cache-file", "Multipass Cache File", - "Multipass cache file", + "Multipass cache file.
