shaka-packager don't ts stream with scte information for generate dash output.

test-scte.zip

I have use last tsmux from gstreamer framework (1.21.1 tag ) for to obtain my test stream. You can build it as follow

git clone https://gitlab.freedesktop.org/gstreamer/gstreamer.git && cd gstreamer && git checkout 1.21.1 && \ meson build -Dpkg_config_path=$PREFIX/lib/pkgconfig -Dc_thread_count=$(nproc) --prefix=$PREFIX \ -Dpython=enabled && ninja -C build && ninja -C build install

Use this gstreamer pipeline for reproduce it:

gst-launch-1.0 videotestsrc is-live=True ! video/x-raw,framerate=60/1 ! videoscale ! video/x-raw,width=1920,height=1080 ! nvh264enc ! queue ! mpegtsmux name=mux scte-35-pid=123 scte-35-null-interval=450000 ! udpsink host=16.5.0.48 port=3006
