Signal 17 (SIGCHLD) error, and "404 Not Found" message in browser #21

Closed joystiller closed 3 years ago

joystiller commented 3 years ago

I can now run the program and I feel like I'm getting closer and closer! However, when I start streaming in OBS, the terminal keeps spitting out repeating error messages about signal 17 like this:

Also, I get a 404 Not Found message in my browser when I go to localhost ot listen to the the stream (tried both Safari and Chrome), perhaps this issue is related?

I've added some additional information about troubleshooting to the readme here: https://github.com/EnvelopSound/Earshot/blob/master/README.md#troubleshooting

I'm guessing this might be a git lfs issue. But if that doesn't solve the problem, please paste the ffmpeg logs here

joystiller commented 3 years ago

Woho! This solved it! The git lfs checkout command didn't work, I had to do git lfs fetch first, then it worked!
