Hello. Trying to use a pipeline below:
gst-launch-1.0 \
videotestsrc \
! video/x-raw,framerate=60/1 \
! videoconvert \
! cudaupload \
! cudaconvert qos=true \
! video/x-raw\(memory:CUDAMemory\),format=NV12 \
! nvcudah264enc name=nvenc bitrate=10000 rate-control=cbr gop-size=-1 strict-gop=true aud=false b-adapt=false rc-lookahead=0 b-frames=0 zero-reorder-delay=true cabac=true repeat-sequence-header=true preset=p4 tune=ultra-low-latency multi-pass=two-pass-quarter \
! video/x-h264,stream-format=byte-stream,profile=main \
! queue \
! wrs. \
audiotestsrc \
! queue \
! wrs. \
webrtcsink name=wrs
But it produces:

(last message repeats infinitely)
As per source code from link, h264parse expects sps-pps picture headers to come before any “slices”. Why could this happen and how to solve this issue?
Same happens when using nvh264enc instead of nvcudah264enc in the pipeline.
