I have a problem with "eject" -functionality crashing randomly. Sometimes I can load and play videos tens of times. Sometimes loading the second or n'th video crashes without any exceptions. I have two classes: Gui and VideoEngine. Gui is a simple qt widget with a rendering area and button for opening new videos to play.
Vlc instance is created only once in VideoEngine constructor:
Code: Select all
VideoEngine::VideoEngine(QObject * parent) : QObject(parent)
{
const char * const vlc_args[] = {
"-I", "dummy",
"--ignore-config",
"--extraintf=logger",
"--verbose=2",
"--plugin-path=C:\\vlc-1.0.3-win32\\vlc-1.0.3\\plugins"
};
libvlc_exception_init(&_vlcexcep);
_vlcinstance=libvlc_new(sizeof(vlc_args) / sizeof(vlc_args[0]), vlc_args,&_vlcexcep);
raise (&_vlcexcep);
_mp = libvlc_media_player_new (_vlcinstance, &_vlcexcep);
raise (&_vlcexcep);
}Code: Select all
void VideoEngine::initVideo(WId windowId, QString fileName)
{
_m = libvlc_media_new (_vlcinstance, fileName.toAscii(), &_vlcexcep);
raise(&_vlcexcep);
libvlc_media_player_set_media (_mp, _m, &_vlcexcep);
raise(&_vlcexcep);
libvlc_media_release (_m);
#if defined(Q_OS_WIN)
libvlc_media_player_set_drawable(_mp, reinterpret_cast<unsigned int>(windowId), &_vlcexcep );
raise(&_vlcexcep);
libvlc_media_player_play (_mp, &_vlcexcep );
raise(&_vlcexcep);
