RaspberryPI 4/ubuntu 19.10 64bit compiled OBS studio

[Filip Stadler]

Just for a test I tried to compile the OBS studio https://obsproject.com/ on my rp4 with 4gb ram.
I did compile but fine on ubuntu but not possible on Rasbian - but I am sure it does its not really optimized using
the rpi4 GPU but it was running but to slow - I did a rtmp stream capture of the desktop also have not
testet using other more small desktop managers

Example
https://www.youtube.com/watch?v=mFT8s6XgGtk (record capture with obs)

Anyway I can do a rtmp fulld stream using just ffmpeg from my video cam in full hd with a Elgato usb3 capture device
but the rpi4 does get very hot so it needs active cooling.

The goal of making my videocamera wireless portable mobile/phone streamning is working but not using OBS
this is my setup https://www.undergroundnews.dk/index.ph ... ming-setup sorry its in danish
but I can stream to my own rp4 at home and restream to other destinations using rtmp but anybody else playing with
simular projects ?

I have been trying to get my rpi 4 to stream out a rtmp stream to youtube.

Code: Select all

Cannot open connection tcp://a.rtmp.youtube.com:1935
rtmp://a.rtmp.youtube.com/live2/<stream key>

Have you seen this error before? I think it has something to do with the raspbian verson of ffmpeg does not have openssl compiled in. But that is just a guess.

BTW there is a version of Ubuntu that runs on rpi 4. Thought not sure how stable it is yet.

[Filip Stadler]

Yeps there is a Ubuntu 19.10 64 bit version at https://ubuntu.com/download/raspberry-pi but the ffmpeg in Rasbian/Buster is OK.

The lack of openssl in ffmpeg is not a big problem - I used stunnel to make rtmpS for facebook stream.

The ffmpeg with buster is:

The only thing I am missing is the support for SRT

[Golly]

I've been doing some research in SRT, but what would be the "first step" in moving RTMP to SRT?

Well it looks easy - you can do udp to srt like UDP--->SRT====SRT<----UDP they included nice tools to do this at github
sudo git clone https://github.com/Haivision/srt
cd srt

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install tclsh pkg-config cmake libssl-dev build-essential
./configure
make

# We need SRT to be installed in the system also

sudo make install

# To Compile a ffmpeg on Rasberry with OMX enable

git clone https://github.com/FFmpeg/FFmpeg.git
cd FFmpeg

sudo -s

export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"

./configure --arch=armel --target-os=linux --enable-gpl --enable-omx --enable-omx-rpi --enable-nonfree --enable-mmal --enable-libsrt

make

This maybe not the right way but you get SRT in the ffmpeg but I am missing some - and places where you would to udp multi or unicast you can gain from using SRT - you can make udp on 127.0.0.1:4002 where the SRT is do the transmission to another SRT that make it available as UDP on a local port so you can get input to ffmpeg/vlc as it was regular so its not very hard to replace rtmp with SRT but I dont know if a SRT module is available for nginx but if SRT is compiled in the ffmpeg you can possible more easy to stuff where you would use non reliable udp transmission.

I would like to compile the ffmpeg just like the one included in my rasbian/debian with all the h264/h264 but
git clone https://github.com/FFmpeg/FFmpeg.git does not includ all the stuff to make it simular
