Question / Help OBS-FTL from source: still 10 second delay

[keybounce]

First, I want to thank Narcogen for the work and help done getting OBS-FTL to compile.

Second, I want to know why it works for you, and not for me.

I am now able to compile OBS-FTL, and it runs. But I still get a 10 second delay.

I did have to make changes to the OBS build script that was there. Here's my current build script:

build(){
  export FFmpegPath=/opt/local/bin
  export QTDIR=/opt/local/libexec/qt5
  pushd .
  cd ..
  mkdir -p build
  cd build
  cmake -DOBS_VERSION_OVERRIDE='17.0.0-ftl.28' ..
  make
  sudo python2.7 ../build_script/build_app.py
  # sudo chown -R :staff OBS.app
  popd
}

archive(){
  pushd .
  cd ../build
  echo "@@ Archiving build to DMG..."
  hdiutil create -ov -fs HFS+ -type SPARSE -volname 'OBS-FTL Install' OBS-FTL.sparseimage
  hdiutil mount OBS-FTL.sparseimage
  cp -r ./OBS.app "/Volumes/OBS-FTL Install/OBS-FTL.app"
  hdiutil detach "/Volumes/OBS-FTL Install"
  mkdir -p dmg
  hdiutil convert -ov OBS-FTL.sparseimage -format UDBZ -o dmg/OBS_Studio-FTL.17.0.0.ftl.28.dmg
  popd
}

build
archive

For comparison, here's the diff from the original:

  popd
 }

The hdiutil commands needed a significant re-work, the old script would not run twice without manual cleanup, and the old "80 MB image limit" was exceeded during the preparation (hence the sparse image intermediate and the compressed final image).

BUT:

1. During compilation, OBS cannot find VLC. No VLC source
2. Docs say to use

1. Stream Type: Beam FTL Service

But that is not found. Only "beam.pro" is found.
3. Even with zero latency, high profile, very fast (settings from the beam site), it still gives me a 10 second delay.

I am stuck. I cannot quite get this to work.

Help me Narcogen, you are my only hope. Just 14 steps to the light side and we'll be done.

You're looking in the wrong place.

Under settings, you need to change "streaming services" to "Beam FTL Service", then change the desired ingest server.

If you just choose Beam.pro from the list of ingest servers, you're still using RTMP.

Ahh ... Thank you!

Now, to test, to stream, to drip water!

Darn!

Well, it works. For a short period. I was able to stream, and move my browser window, and saw the "infinite zoom" move in real time.

Overflowing a large malloc???

Needless to say, the crash was ... too fast :-)

But I have low latency, now to figure out how to make it work.
