Im receiving the following error continuously from my rtsp client pipeline.
im really not sure why this is occuring and am hoping someone here has some
idea :)

We publish an rtsp stream out from a device and display it real time on
another device.

Server pipeline:

imxv4l2src capture-mode=3 fps-n=15 ! video/x-raw,width=1280,height=800 !
tee name=t ! videocrop name=crop ! queue ! appsink name=raw t. ! fisheye
name=project projection=rectilinear interpolation=midpoint !
video/x-raw,width=1024,height=768 ! appsink name=appproject

This produces 2 streams that are passed to an appsink in order for our
rtsp-server to attach clients on request. So the next half of the server
stream is:

appsrc name=raw is-live=true ! queue max-size-buffers=3 leaky=downstream !
videorate drop-only=true average-period=2000000000 ! videocrop name=crop !
imxipuvideotransform name=transform ! capsfilter name=caps caps=video/x-raw
! imxvpuenc_h264 name=h264 bitrate=4096 ! rtph264pay name=pay0 pt=96

Then on the client system we display the stream with the following pipeline:

rtspsrc name=videosrc buffer-mode=1 protocols=tcp ! queue name=videoqueue !
rtph264depay name=depay ! h264parse ! imxvpudec name=decode !
imxipuvideotransform ! imxipusink name=sink sync=false

First we get this once :
0:00:02.786696666  2811 0x37d02030 WARN       codecparsers_h264
gsth264parser.c:1736:gst_h264_parse_pps: failed to read SE

gsth264parse.c:510:gst_h264_parse_process_nal:<h264parse2> failed to parse

Thereafter we get this from what looks like every frame:

0:00:13.371507669  2793 0x37c02030 WARN       codecparsers_h264
gsth264parser.c:1814:gst_h264_parser_parse_slice_hdr: couldn't find

Thank you in advance,
