RetroPie 4.5.1 - control and/or emulators lock when attempting to stream to twitch - also, how do I stream to twitch?

As you can see, no mention of the streaming at all, though the libx264 stuff may be associated. A quick brute-force search of the various log directories doesn't find anything about "twitch.tv" either.

Guide used:
Essentially, none. I've looked at the following:
https://retropie.org.uk/forum/topic/18303/livestreaming-to-twitch-on-retropie-4-4/2
http://www.retroarch.com/index.php?page=recording

Especially the latter seems like it should be applicable, but there's no option to set a recording destination. There is, however, the option to add a streaming location with "Twitch" streaming type. I have entered my Twitch key here in the rtmp://live.

/$YOUR_STREAM_KEY format.

Relevant config lines from retroarch.cfg:

video_stream_config = ""
video_stream_port = "56400"
video_stream_quality = "1"
video_stream_scale_factor = "1"
video_stream_url = "rtmp://live.
/<stream id edited out>"

Emulator: lr-snes9x2010, lr-fceumm

How to replicate the problem: Start up the in-emulator menu, select "Start Streaming" after the above config. SNES loses the controller, NES loses the controller and locks up after about 5 minutes (at least apparently - the music stops. Either way, I need to alt-tab out and Control-C to kill the process.)

Any insight on whether the old instructions work and I need to do some weird config file edits, or if there's a new way to do things and I'm missing a step?

(Edit: Updated the topic to encompass both questions - emulator lockup/control failure is the symptom, but the ultimate problem is that I don't seem to be able to stream to twitch)

For what it's worth, here's a picture of the settings under "Recording..." in RetroArch in case it helps:

You may be hitting a RetroArch bug that was fixed a few months back - https://github.com/libretro/RetroArch/issues/8782.
Can you start with the emulator with verbose logging from Runcommand menu and then post the /dev/shm/runcomman.log to pastebin.com ?

@mitu The system was built from the retropie-setup script as of 2 days ago, so presumably whatever I pulled would have had this bugfix already? Maybe it's not working the way I think it should, but I notice it pulling a bunch of stuff from git.

As for the logfile - hey, look at that, verbose logging. Not sure how I missed that when I was looking for it:

Thanks for taking a look.

Not quite, RetroPie doesn't include the latest & greatest, it's using version 1.7.6 (which doesn't contain the fix). In fact, you can see at the top of the log

[INFO] [recording] twitch streaming key empty

which means that it doesn't correctly get the Twitch settings correctly.

@mitu said in RetroPie 4.5.1 - control and/or emulators lock when attempting to stream to twitch - also, how do I stream to twitch?:

Ah-hah. I obviously can't read logs anymore. I blame it on already spending the entire day doing the same. ;)

Do you have any input on whether I'm likely to brick my setup if I go over to that github and rebuild retroarch from source? It looks like it's just a binary file sitting in /opt/retropie/emulators/retroarch/bin, so I should be able to back that up and drop it in as a replacement... in theory.

Either way, thanks for the second set of eyes - although I'll be back if it still doesn't work. :D

(edit: Okay, maybe not back like that - I do understand that this is a bug in the existing retroarch that's bundled with RetroPie, and it'll probably just be fixed on next release - I was trying to be funny, honest :P)

[mitu]

You can install the snap/flatpak packages for RA - but to get the latest version from RetroPie, you'd just need to modify the install script - https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/emulators/retroarch.sh - and in the sources_retroarch function remove the branch number and the patches applied (they won't apply cleanly). See here.

Then rebuild RA from source from the RetroPie-Setup menu and re-test your setup.

EDIT: Note that if you modify locally the scriptmodule, updating the RetroPie-Setup script will not work. You'll have to reset the modifications with

cd $HOME/RetroPie-Setup
git reset --hard

before updating (it will erase your local modifications).

Huh. Okay, that seems simple enough.

And hey, look at that, it streams! :D

Again, I very much appreciate the help.

Thanks for testing, that clears it up.
