Question / Help Streaming don't work

[DevChuckNorris]

Hello,

I have a problem if I want to stream, i don'get any error message but the stream is still offline, and OBS don't send data to the streaming server.

This happen in the console:

info: [rtmp stream: 'default_stream'] Connection to rtmp://live.twitch.tv/app successful
[SWR @ 0x7f8b7800cb80] Failed to set option
error: swr_alloc_set_opts failed
error: audio_input_init: Failed to create resampler

Kind regards

what version of OBS are you using and how did you install it?

I'm seeing this too. Ubuntu 14.10 64-bit, compiled from source using the instructions in INSTALL. Log from running the program: https://gist.github.com/anonymous/a3c6a81ec60559412237

What version of FFmpeg is installed?

 

[JPL]

Compiled from source, as specified in the Debian/Ubuntu compilation instructions.

So FFmpeg is self-built from the FFmpeg repository? It's very unusual to get this sort of FFmpeg error because I've been using FFmpeg for a long time without ever having encountered this sort of problem, but I've always compiled it myself from their repository, so I was asking if perhaps you got FFmpeg from somewhere else in this case.

 

[JPL]

Don't think so? I followed the Ubuntu compilation instructions to the letter... My setup is very standard, I actually reinstalled Ubuntu 14.10 because I was worried I'd done something in a previous version to give me a non standard multimedia stack.

Hmm, when I try to run ffmpeg (the self-built one) I get this error:

ffmpeg: relocation error: /usr/lib/libavfilter.so.5: symbol avpriv_vga16_font, version LIBAVUTIL_54 not defined in file libavutil.so.54 with link time reference

doesn't

One more bit of info: this also happens on my laptop (Samsung ATVI Book 9 Plus) using the compilation instructions given, log here:

you aren't using the correct ffmpeg version. it's having an issue doing the resampling.

 

[JPL]

Like I said, I followed the compilation instructions included with OBS so either there's a bug in the current git head of ffmpeg or the instructions have an error.

It will be months before the Ubuntu ffmpeg situation is rectified in 15.04, those of us using 14.10 need a way to run OBS until then.

 

[ubuntuaddicted]

you downgrade to 14.04.1. one could argue that anyone dependent on the tools available to them for free should be on an LTS release anyway. this is my opinion though..... i wish i could help but i couldn't get it to compile in a 14.10 vm and it wasn't worth my time so i gave up. with ubutech, llc and linux tech and gaming podcast i'm over worked and underpaid. lol

 

[skwerlman]

I also had issues compiling on 14.10; it needed two packages that weren't listed in the instructions. I've made a PR which fixes the issue.

Even so, it still won't stream: https://gist.github.com/skwerlman/ef5d6018e5a753b7043c

Hmm, when I try to run ffmpeg (the self-built one) I get this error:

it's because OBS can't use that ffmpeg that you self-compiled and installed. it's not coded to use those libraries.

Just came across this PPA that provides FFmpeg 2.4 on 14.10:
https://launchpad.net/~kirillshkrogalev/+archive/ubuntu/ffmpeg-next

However when I install that version, I still get the same error when trying to stream in OBS.

 

[ubuntuaddicted]

i strongly suggest you either learn how to make obs compile against custom ffmpeg libraries or you just downgrade back to 14.04 if you really want to use obs. there's other gui based streaming software out there if you look. i won't advertise it though as it's probably frowned upon here.

I was able to stream with OBS from 14.10 using the PPA mentioned in this thread:

Hopefully this will continue to work until 15.04 removes the need for an FFmpeg PPA entirely.
