Hi Daniel,


When I run osgmovie in testing it's always from the console, testing with and without SDL for audio, so far I haven't had a problem like your describe.  The interaction with the DISPLAY variable is a bit odd, perhaps SDL/Audio subsystem on your system is doing something odd.


FYI, I use Kubuntu for dev work, currently on 15.10.


Robert.

Hello all:
    When I write a program according to osgmovie example using OSG 3.4 and SDL2. It works fine when I run it under GUI windows. But if I run my program in ssh terminal, an exception occurs, and video stops on first frame. And the original osgmovie has no problem. Does anybody know the reason? Below is the output:


ffmpeg::open(/film/rio.mov) size(1920, 816) aspect ratio 1
Attaching FFmpegAudioStream
FFmpegAudioStream::setAudioSink( 0x9d7f80)
Assigning 0x9d7f80
GraphicsWindowX11::realizeImplementation() Already realized
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused


FFmpegDecoderAudio::run : unhandled exception
Finished FFmpegImageStream::run()
FFmpegAudioStream::setAudioSink( 0)
Assigning 0
Calling avformat_close_input(0x8c1fe8)


With best regards
daniel
