Ubuntu 15.10 64-bit deb package not working #27

Closed Byteschmiede closed 8 years ago

Byteschmiede commented 8 years ago

I tried both installing from deb package and compiling from source. Everytime while starting it said something like segfaulting without stack trace

bill-auger commented 8 years ago

could you give me more information about your OS - like the output of:

uname -a
gst-launch-1.0 --version

the debug build will print much useful information - could you try compiling the debug version like:

  cd Builds/GnuMakefile
  make
  ./build/av-caster-dbg

if you are on LCTV? feel free to come into my channel and i can help you in real-time https://www.livecoding.tv/bill-auger/ - also i have just setup a gitter chat https://gitter.im/bill-auger/av-caster

Linux laptop 4.2.0-16-generic #19-Ubuntu SMP Thu Oct 8 15:35:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

The debug version also not starting .. no stack trace

I just followed you on LCTV :)

ok i was able to reproduce this on a fresh install of ubuntu 15.10 64bit

for me tho when i compiled it manually it ran properly - could you try again building the debug binary after installing all of the packages below

  sudo apt-get install build-essential libfreetype6-dev libgstreamer-plugins-base1.0-dev libx11-dev libxcursor-dev libxinerama-dev freeglut3 gstreamer1.0-plugins-bad gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly libfreetype6 libgl1-mesa-glx libx11-6 libxcomposite1 libxcursor1 libxext6 libxinerama1 libxrender1

  cd Builds/GnuMakefile
  make
  ./build/av-caster-dbg

These packages are already installed on my system ... still getting segfault error after building

@csNewscope

i think the problem may be that the 64bit build needs to be built against gStreamer v1.6 and travis is using a much older version - i may actually need to raise the minimum requirement to gStreamer v1.6 (which for debian is sid and ubuntu is wily) and try to get travis to build against gStreamer v1.6 - so for now i will be deleting the 64bit deb packages

i really do not know why you are having trouble running your locally compiled binary tho - i have installed ubuntu 15.10 amd64 today on two different boxes and the av-caster compiled and ran successfully on both - i have uploaded a binary that i compiled on ubuntu 15.10 amd64 --> https://github.com/bill-auger/av-caster/releases/download/v0.15/av-caster-v0.15-amd64.tar - if this will not run for you there must be something specific to your setup that is preventing it

btw - you are not trying to run this in a VM are you ? av-caster will not run in a VM

Byteschmiede commented 8 years ago

I've tried your compiled version .. still not working.

No i'm not running that in a VM :/

bill-auger commented 8 years ago

the only caveats i can think of that i have not menrtioned are that i think that a sound card and ALSA are a strict requirement also and your xserver must support xv rendering i could compile a debugging version for you to run in gdb - maybe without audio or video preview - other than that i am running out of ideas

bill-auger commented 8 years ago

@csNewscope there is now a working 64bit deb package for ubuntu 15.10 a new repo if you would care to try that :) http://software.opensuse.org/download/package?project=home:bill-auger&package=av-caster

Byteschmiede commented 8 years ago

Hey i downloaded the amd64 deb .. still not working.. Ubuntu showed me the stacktrace and i clicked on "Submit" maybe you get a message or something with informations

Hi Bill. I'm having the same issues. I didnt want to create another issue if it's the same thing. Is it possible to provide some sort of --debug flag while av-caster is under development? I installed it fine from opensuse, but when I run $ av-caster (or any other command trying to start the program), there's a VERY quick window popping up, it closes and command line tells me there was an error code of 255 (?).

@ThomasBS -

there are still some issues with the packaged versions - i should probably update these ASAP seeing as most ppl seem to prefer this install method - most errors now are related to hardware devices - if it is possible for you to compile from the current master branch i have added debugging traces to the release build and some feature switches

once you have av-caster v0.15.202 or later you should see some errors in red when running from the command line which may pinpoint the problem

also you can run av-caster --help to see some options under 'FEATURE SWITCHES' - the --no-media option will almost certainly allow the program to start but in an essentially useless state - try the others to see if you can get a usable configuration

bill-auger commented 8 years ago

the package in the OBS repo has been rebuilt and now corresponds to the current master branch and tag v0.15.203
