Due to the way things are done,
Pids can differ esp. if a standard is not followed.
North of the equator Video and Audio Pids etc normally use 256 257 4096 etc, it all works

I see it appears the default for Pluto FW 0303 in Pluto also follows the Norm.

Is there any way to alter PIDS sent Via the Line used in OBS rtmp://192.168.2.1:7272/etc etc,
Or Is there way within the 0303 interface to add/alter PID assignment.
Some Receivers I have found are ok and will work with any PID, and others it needs to be correct.

Thank You

Hi Rob

I can't see one, but you could always edit the source code and re-compile if you build the toolchain. Why not ask Evariste ? It may be rather complicated if it appears in several different bits of code. Instructions here https://github.com/F5OEO/tezuka_fw/tree/main

Note changing those PIDs would probably break many receivers.

Of course if you are generating your own UDP transport stream and sending that to the Pluto, rather than doing it on the Pluto sending it as RTMP, just set the PIDs to whatever you want. This is what the " -streamid 0:256 -streamid 1:257 " is doing in the batch scripts I use and no doubt similar in applications like DATV Easy. In 0303 you need to set DATV mode and UDP input.

e.g. as highlighted below.

c:\ffmpeg\bin\ffmpeg -f dshow -i video="OBS-Camera" -thread_queue_size 512 -f dshow -i audio="OBS-Audio" -vcodec hevc_nvenc -s 1280x720 -bf 0 -pix_fmt yuv420p -b:v 220k -r 15 -preset slow -profile:v main -rc cbr_hq -rc-lookahead 5 -acodec aac -aac_coder twoloop -ar 48000 -ac 1 -b:a 32k -f mpegts -muxrate 325k -streamid 0:256 -streamid 1:257 -metadata service_provider="VK3IE" -metadata service_name="Rob" -max_delay 2500000 -pcr_period 40 -pat_period 0.4 "udp://192.168.2.1:8282?pkt_size=1316"

Thanks Mike
I will absorb this,

A bit above my Pay Level. and getting in touch with Evariste, not an easy find.

Some receivers dont care about PIDS to much and work 100%
Others if the numbers aint set no Input for you.

Again thanks
Cheers
