Hallo,
there is file gst1-plugins-bad-1.14.4/gst/videoparsers/gsth264parse.c
Inside this file there is a function: gst_h264_parse_negotiate
which calls
caps = gst_pad_get_allowed_caps (GST_BASE_PARSE_SRC_PAD (h264parse));
GST_DEBUG_OBJECT (h264parse, "allowed caps: %" GST_PTR_FORMAT, caps);
In an error condition (which sporadically occurs) I get
h264parse gsth264parse.c:420:gst_h264_parse_negotiate:<RecorderH264Parser> allowed caps: (NULL)
What does it mean?
1) That SRC_PAD of h264parse does not offer CAPS at all?
2) That negotiation process was already execute and was not successful and there are no matched CAPS between H.264 parser and elements connected to src pad
I assume it is case 1)
Where are the CAPS set for h264parse SRC_PAD before the function gst_h264_parse_negotiate is called?
Best regards,
Marie
