From a674d9eff2665327fa534c2edbcb2cb8ed71d815 Mon Sep 17 00:00:00 2001 From: Matthieu Bouron Date: Wed, 11 Dec 2013 18:08:26 +0000 Subject: [PATCH] vaapidecode: query downstream caps features like GLTextureUploadMeta. Fix vaapidecode to correctly report caps features downstream, when a custom pipeline is built manually. https://bugzilla.gnome.org/show_bug.cgi?id=719372 Signed-off-by: Gwenole Beauchesne --- gst/vaapi/gstvaapidecode.c | 72 ++++++++++++++++++++++++++++++++------ 1 file changed, 62 insertions(+), 10 deletions(-) diff --git a/gst/vaapi/gstvaapidecode.c b/gst/vaapi/gstvaapidecode.c index b3519a9761..5d45b025a0 100644 --- a/gst/vaapi/gstvaapidecode.c +++ b/gst/vaapi/gstvaapidecode.c @@ -110,10 +110,12 @@ gst_vaapi_decoder_state_changed(GstVaapiDecoder *decoder, const GstVideoCodecState *codec_state, gpointer user_data) { GstVaapiDecode * const decode = GST_VAAPIDECODE(user_data);
