From 9b664e60d94b3fb43b810ebd87838c2d8ac91e44 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sebastian=20Dr=C3=B6ge?= Date: Tue, 28 Jan 2020 22:07:44 +0200 Subject: videoaggregator: Don't configure NULL chroma-site/colorimetry If there's no known value in the best caps then the functions to convert them to strings will return NULL. Having the fields not in the caps is not a problem, having them with a NULL value however will cause negotiation failures. --- gst-libs/gst/video/gstvideoaggregator.c | 17 ++++++++++++----- 1 file changed, 12 insertions(+), 5 deletions(-) diff --git a/gst-libs/gst/video/gstvideoaggregator.c b/gst-libs/gst/video/gstvideoaggregator.c index 886121b02..0d448a803 100644 --- a/gst-libs/gst/video/gstvideoaggregator.c +++ b/gst-libs/gst/video/gstvideoaggregator.c @@ -898,14 +898,21 @@ gst_video_aggregator_default_update_caps (GstVideoAggregator * vagg, GST_DEBUG_OBJECT (vagg, "The output format will now be : %d with chroma : %s and colorimetry %s", - best_format, gst_video_chroma_to_string (best_info.chroma_site), - color_name); + best_format, + GST_STR_NULL (gst_video_chroma_to_string (best_info.chroma_site)), + GST_STR_NULL (color_name)); best_format_caps = gst_caps_copy (caps); gst_caps_set_simple (best_format_caps, "format", G_TYPE_STRING, - gst_video_format_to_string (best_format), "chroma-site", G_TYPE_STRING, - gst_video_chroma_to_string (best_info.chroma_site), "colorimetry", - G_TYPE_STRING, color_name, NULL); + gst_video_format_to_string (best_format), NULL); + + if (best_info.chroma_site != GST_VIDEO_CHROMA_SITE_UNKNOWN) + gst_caps_set_simple (best_format_caps, "chroma-site", G_TYPE_STRING, + gst_video_chroma_to_string (best_info.chroma_site), NULL); + if (color_name != NULL) + gst_caps_set_simple (best_format_caps, "colorimetry", G_TYPE_STRING, + color_name, NULL); + g_free (color_name); ret = gst_caps_merge (best_format_caps, gst_caps_ref (caps)); -- cgit v1.2.1
