I have followed this to the letter using clean, new Pi lite and desktop
While I have tried apt-getting all the libraries required, I did decide in
the end to just build them all from the instructions given, I never did get
libaom to install so I skipped that, I don't think I needed it.
All I want to do is transmit video, no audio
To install the SRT library I used the following in my .sh file and it does
create the correct files in the ffmpeg_sources folder - the complete .sh
file is attached
There were several other issues like having to install libunistring-dev to
work around errors but in the end I think I got a clean compile and install.
However the ffmpeg -protocols still does not show the SRT protocol and
ffmpeg does not work with a SRT output.
