[gst-devel] rtp transmit occur "not-negotiated (-4)" error

[guodecn]

Marco Ballesio,
I have follow your two advices, add the codec_data property or set
config-interval=1, the error is still same to before.

I have set the GST_DEBUG=3, and capture the log, both server and client log
are all in the attach file.
I will check my machine evirenment about x264enc, also I will continue to
debug with the new log.
Thank you very much for your fervor.
