Hello! I want to send an encoded h264 stream over RTP. There are two h264 encoders in gstreamer I found: ffenc_libx264 and x264enc. Both fails. The stream encoded by x264enc is rejected by the rtph264pay:  gst-launch v4lsrc device=/dev/video0 ! x264enc ! rtph264pay ! fakesink  Setting pipeline to PAUSED ...  Pipeline is live and does not need PREROLL ...  Setting pipeline to PLAYING ...  New clock: GstSystemClock  x264 [warning]: width or height not divisible by 16 (160x120), compression will suffer.  x264 [info]: using SAR=1/1  x264 [info]: using cpu capabilities: MMX2 SSE2 SSE3 Cache64  ERROR: from element /pipeline0/rtph264pay0: The stream is in the wrong format.  Additional debug info:  gstrtph264pay.c(673): gst_rtp_h264_pay_handle_buffer (): /pipeline0/rtph264pay0:  AVC H264 is not supported yet  Execution ended after 182851632 ns.  Setting pipeline to PAUSED ...  Setting pipeline to READY ...  Setting pipeline to NULL ...  x264 [info]: slice I:1     Avg QP:15.62  size:  7192  x264 [info]: mb I  I16..4:  0.0%  0.0% 100.0%  x264 [info]: SSIM Mean Y:0.9969846  x264 [info]: kb/s:1438.4  FREEING pipeline ...
