Hi, I am trying to get a video stream from a device (a webcam with specific format). I can get the stream using VLC but not through libVLC. Command line in VLC is : vlc dshow:// :dshow-vdev="MyDevice" :dshow-adev=none :dshow-size=200x400 :dshow-chroma=YUYV Same options in libVLC fail to ge...

Hi, I try to play VR180 (from Lenovo Mirage Camera) or 360 equirectangular video BUT without taking into account the fact that it is a specific video. I would like raw data without distortion correction (the same as when I play them into WMP, 360 mode disabled). Is there any option in command line t...

Here are the messages when trying to read the file (6K 3D file) freetype error: LayoutParagraph(): Invalid max width freetype error: LayoutParagraph(): Invalid max width freetype error: LayoutParagraph(): Invalid max width freetype error: LayoutParagraph(): Invalid max width freetype error: LayoutPa...

Hi,

I tried to play Insta Pro video samples (https://www.insta360.com/product/insta360-pro) with VLC 3.0.3 and it failed for 8Kand 6k3D, it only plays 4K 3D video. Is there any way to make VLC play this kind of file ?
Best regards,

I had the same concern about reading video in OpenGL texture but without modifying the libVLC sources I think this is not something easy to do. I used as basis the SDL tutorial and resulting performances are pretty good (but I only load a single video and apply it as texture with a simple shader on ...

I think it would be difficult to exploit the OpenGL texture out of its context. If you want the OpenGL texture you need the OpenGL context too (context created by VLC to draw when using OpenGL). This is not something exposed I think. I suppose that you need an OpenGL texture to display video on a 3D...

SpatialAudio module crash : Waiting to find a solution, I would like to clean my development to avoid the end crash. Is there any way to ask VLC not to use ambisonic audio plugin ? reading the 4 channels as mono channels maybe ? More information about the crash: in the Visual 2013 console I can see...

I have posted bug reports for those 2 issues. I checked some elements before posting to better explain the errors. You'll find here my conclusions: - ambisonic sound seems to make something wrong into libVLC mediaplayer since libvlc_media_player_stop generates an error. I did not find a way to make ...

I have another bug I cannot fix : with some videos (those with spatial audio plugin used it seems) while stopping media player a breakpoint is reached (happen in spatialaudio_plugin.dll calls), really a strange issue (crashing while quitting is not really "annoying" for user who won't see ...

Hi, In fact, metadata is already injected the file I use (since I can read it in VLC or Windows video player in 360 directly), but the viewpoint cannot be set up ( libVLC log in console [ main vout display error : Failed to change viewport ] ). I do not know how to use this method but ideally I woul...

Thanks, I will have a look. I found "libvlc_video_update_veiwpoint" (https://www.videolan.org/developers/vlc/doc/doxygen/html/group__libvlc__video.html#gab4ca65a36eb864227287ff6a74c64af0) in libvlc_video_controls should do the work. I tried to use that creating a new viewpoint for each fra...

Hi, I developped an OpenGL 360 video player (to display the video into a head mounted display) but I still need to implement 3D sound management. Does someone know how I could modify in real time the sound perception using pitch/yaw/roll, quaternion or rotation matrix (and HRTF obviously) ? Best reg...

The conversion/scale from video resolution to texture resolution (not the same in my initial code) was the point which made the pixels copy slow. Using the video resolution as texture resolution seems to fix the "pixels copy slowdown" behaviour.

Hi, I am trying to do 360 video OpenGL rendering using libVLC, applying a shader to lookup into the texture and get only the texture area needed regarding the user's gaze & FOV. The only way I found to do that with libVLC was to use "libvlc_video_set_callbacks" to get the pixels data a...
