libvlc_new return null on macos 13 with qt 6.4

[liusz_318]

Hi,
I wrote a piece of code to learn playing video with libvlc, the code works well on windows, but doesn't work on my mac book pro(the macos version is 13.2), and I use qt 6.4. I found that libvlc_new returns null on macos. My code is like:

Code: Select all

libvlc_instance_t *_vlcInst = NULL; libvlc_media_t *_vlcMedia = NULL; libvlc_media_player_t *_vlcPlayer = NULL; libvlc_event_manager_t *_eventManager = NULL; const char *tempArg = ""; const char *vlc_args[10] = {"-I", "dummy", "--no-osd", "--no-stats", "--ignore-config", "--verbose=2", "--no-video-on-top", "--no-video-title-show", "--no-snapshot-preview", tempArg}; int argc = sizeof(vlc_args) / sizeof(vlc_args[0]); qDebug() << "argc: " << argc; _vlcInst = libvlc_new(argc, vlc_args); if(!_vlcInst) { qDebug() << "create vlc instance failed: " << libvlc_errmsg(); return; } qDebug() << "create instance ok"; _vlcPlayer = libvlc_media_player_new(_vlcInst); if(!_vlcPlayer) { qDebug() << "create player failed."; return; } qDebug() << "create player ok";

How would I use libvlc_new on macos? Any help will be appreciated.

Most common reasons: invalid arguments given or plugins cannot be found.

Hi Rémi,

Thank you for your reply.

I tried libvlc_new(0, NULL), and copied the "plugins" folder into the app folder, and also copied the folder to myapp.app/Content/MacOS/, but libvlc_new still return NULL. Could you give me more hint?

Have you tried setting the VLC_PLUGIN_PATH environment variable?
