Bug Report m3u8 format not working


New Member

I'm trying to record in m3u8 format but at 1:17 the recording stops for some reason. Then you can't stop OBS completely by pressing the stop recording button unless I remove it from the task manager. What makes this possible? All at exactly 1:17. There are 1 m3u8 file and 41 .ts extension files and no more will be created.

obs close button, not stop OBS...

process freez...

Restart obs, and upload last logfile

Has any progress been made on this?

I recently had to update OBS from version 21 to 25 in order to use the iPhone's OBS Camera app, but the update DESTROYED my ability to stream over a local network via the record button.

I have it set up to hit "Start Streaming" to send our feed to YouTube & Facebook, and "Start Recording" would record an m3u8 file to my web server within the building, so other TVs on the property could access the feed via VLC. (raspberry pi's running a scripted command "vlc http://hostname/.../stream.m3u8")

My issues are IDENTICAL (aside from the 1:17 timestamp) to what the OP said in his first post on this thread. I've messed with all sorts of settings but can't get this working the way it did before the update. I feel like something in OBS's File I/O got messed up in an update, at least when it comes to the m3u8 format.

I know it's a really unusual use-case (most people just stream to a private RTMP server), but I don't have that option. I just want a once functional feature to work again.
