While documentation can always be better I don't agree in this case it's "quite lacking". vlcj even provides a simple example in its test sources showing how to use this dialog API.

Your follow-up question has no solution via the LibVLC API AFAIK.

The MediaPlayerFactory has a dialogs API for exactly this purpose.

LibVLC will call you back when it needs to display a dialog, but then it's up to you to display a dialog or whatever.

Yeah sorry, I translate end reached to finished in my own library. Oops.

There is a "finished" event.

I don't know about this specific problem, I just wanted to mention there's a new native thumbnailer API provided with LibVLC 4.x that might be useful to you, look for e.g. libvlc_media_thumbnail_request_by_time. It's much easier IMO than doing set position and waiting for position changed and snapsh...

I see this quite often when using VLC 3.x with my own library that uses LibVLC.

Seeking like that is a LOT better in VLC 4.x, but that's not yet generally available of course.

I don't know about playing RTSP streams specifically, but generally you can specify a start time (and end-time or duration if you want too), e.g. from the command line --start-time=30. Or if you use LibVLC, you pass e.g. ":start-time=30" as a media option when you play the media. The value...

Ah, I remember the mailing list discussion but didn't realise this was added back in.

Thanks for the suggestion.

I'm fine with that, thanks, I can call a native free.

It just seemed like maybe it's something that would be better encapsulated, other native API in LibVLC has destroy counterparts that's what prompted my question.

A libvlc_video_viewpoint_t is created by libvlc_video_new_viewpoint(): LIBVLC_API libvlc_video_viewpoint_t *libvlc_video_new_viewpoint(void); IIRC this used to be able to be freed by libvlc_free, but as libvlc_free has been removed what now is the correct thing to do here? Should there be a correspo...

Do you really need to worry about resizing the buffer? When I do stuff like this, I keep the buffer the same size as that reported for the media, and then simply scale the output to fill my window (or texture), preserving aspect ratio. By scaling the output I mean setting some operation on the graph...

Probably you need to look at subitems.

So given your current libvlc_media_t (for the m3u with one item), use libvlc_media_subitems to get the subitems (each entry in the m3u will be a subitem).

All the streams are playing at the same time? When I did something similar before, not using VLCKit, I wrote a custom layout that let me "focus" one of the streams. The custom layout changed the position and size of the various player panes without doing anything related to the media playe...

VLC/LibVLC 4.x, currently in development, has new callbacks for OpenGL. LIBVLC_API bool libvlc_video_set_output_callbacks( libvlc_media_player_t *mp, libvlc_video_engine_t engine, libvlc_video_setup_cb setup_cb, libvlc_video_cleanup_cb cleanup_cb, libvlc_video_update_output_cb update_output_cb, libv...

Maybe libvlc_media_slaves_add is what you need. It has audio and subtitle types.

I am no expert on this, but I suppose certain buffer formats might require e.g. aligning to 8/16/32 bit boundaries and that could explain the discrepancies you are seeing. So e.g. if the video height is 500, you'd actually need a buffer height of 504 to hold it (504/8 = 63.0 whereas 500/8 = 62.5). I...

From a quick look, the only thing I do different is use RV32 format and a pitches value of width*4.

(I'm not saying RV32 is necessary but it was the only useful format I could get to work with the UI toolkit I was using).

You are definitely allocating enough memory for your *3 buffer size?

What do you want to know? My implementation is deeply integrated in a Java library and I can't just cleanly pull the code out unfortunately.

Did you try and find your device using these other API methods? libvlc_audio_output_list_get libvlc_audio_output_device_enum libvlc_audio_output_device_list_get If you can find your device one of those methods will have the precise device string you need to set when you call libvlc_audio_output_devi...

Honestly, I'm far from being knowledgeable on OpenGL... Anyway, I said before my implementation is deeply integrated into library code so it's a bit difficult to extract a code snippet. The best I can provide here is some pseudo code showing how I initialise the callbacks and link them to the LWJGL ...

A brief foot-note from me, I was simply unable to get VLC 4.x building with Qt from contribs no matter what I tried. What was successful for me ultimately was to download and build the latest Qt source package in some external directory, and set the PKG_CONFIG_PATH to the resulting pkgconfig directo...

@MikOfClassX What code snippet did you want?

Hmm... I had a previous version of Qt installed (for building earlier versions of VLC) and building the newer Qt and QtQuick from the contribs directory worked for me just with just those make commands you used. Anyway hopefully you can get past that, and if so I think the next step to make vlc's bu...

I also needed to do this: I still don't have myself a working build this way, but this might get you one step further.

BTW Any success with LWJGL ? If you're asking me, then "yes"! I use my own build of vlc-git, and I have those new video callbacks working very nicely in an LWJGL application (on Linux). I was actually gob-smacked that it worked so easily, I knew next to nothing about OpenGL when I built t...
