Hi Everyone,
I am trying to pipe my camera but I am keep having issues , here below the code.

#!/usr/bin/env bash
set -euo pipefail

OUTDIR="$HOME/cam_hls"
mkdir -p "$OUTDIR"

libcamera-vid \
--width 1280 \
--height 720 \
--framerate 30 \
--codec h264 \
--profile baseline \
--level 4.0 \
--bitrate 4000 \
--inline 1 \
--intra 1 \
--nopreview \
--timeout 0 \
-o - | ffmpeg -hide_banner -nostdin -y \
-y -loglevel info \
-use_wallclock_as_timestamps 1 \
-fflags +genpts \
-probesize 10M \
-analyzeduration 10M \
-f h264 -i - pipe:0 \
-c:v copy \
-an \
-f hls \
-hls_time 2 \
-hls_list_size 8 \
-hls_flags delete_segments+programme_date_time \
"$OUTDIR/index.m3u8"

when launching it with sudo bash -x /usr/local/bin/cam-loopback.sh, below what happens:
I see code
