As a reference, here is the actual code I'm using: ZVideoLanThumbnailer::ZVideoLanThumbnailer(const Char *in_path, UInt in_with, Double in_time) : m_Width(in_with), m_ThumbnailsTime(Int64(in_time * 1000)), m_ThumbnailsPath(in_path), m_Media(NULL), m_MediaEventManager(NULL), m_Player(NULL), m_PlayerE...

Hi mfkl, I did but I'm essentially using the same C++ code and the migration (3.0 to 4.0) has several issues. Either the mechanics are broken or fundamental changed so it's hard to tell as there is, to my knowledge, no source code examples that are up to date or that could be compiled on Windows wit...

Marvelous, thank you!

thank you mfkl, to be clear, the thumbnailer code works well with libvlc 3.0 C++ but the same code fails with libvlc 4.0 C++, see log: [00000072dccf5c68] main generic debug: no video converter modules matched [0000020aa7c8f0e0] main filter error: Failed to create video converter [00000072dccf6298] m...

Hi Remi, maybe I did not explain the issue correctly because it seems like a legitimate feature. To make things clear, whenever a video is playing there is a triangle icon that fades in and out. Whenever a video is stopped there is a square icon that fades in and out. I'm simply interested in turnin...

Thank you for your input sherington, I've looked at vlc_thumbnailer_RequestByTime and it seems like something I would use eventually. I dont see a mechanic to output the file so it would be great if there is any example I could chew on. 4.0 seems to be under heavy development so it would be best tha...

Greetings,

Getting the hang of 4.0. I'm wondering how to get rid of the Play/Pause, etc icons overlay whenever the media state changes?

thank you,

Greetings, Using a similar technique as the link below, my thumbnailer works well in 3.0 but fails in 4.0 (~may 2020 build). https://github.com/videolan/vlc/blob/master/doc/libvlc/vlc-thumb.c log: [000001a1287bec20] main filter error: Failed to create video converter [0000003a67af5dc8] main generic ...

I just found about libvlc_MediaPlayerBuffering = 100. I think I'm all set. YouTube works fine while Vimeo does not. Oh, well.

I think I'm getting the hang of it, render to textures always baffles me though. I understand it would be more efficient with 4.0 but last time I checked, webm was not stable so I might give it another try eventually. As previously suggested, here is the new addition: void ZVideoLanMovie::UnlockMute...

Thank you for your support, I've been looking at the repo but I dont see anything particular regarding streaming. The setup is on the spaghetti side so I've extracted the essential. With this config, libvlc_media_new_location is hit but libvlc_video_get_size returns false and libvlc_video_set_format...

hummm, I'm a bit in the blind here. Is there any working example (Windows ideally) I could get my hands on?

Thank you for your input mfkl, I’m not familiar with the C# api, any idea how this parsing operation would translate to C++?

Greetings, Is there any example I could chew on how to stream YouTube videos? v3.0.11 Opening url with libvlc_media_new_location. Setting libvlc_video_set_format_callbacks then play. The event libvlc_video_set_format_callbacks never fires, neither does libvlc_MediaPlayerVout. Looking at the debug, a...

Greetings, I'm in the midst of rendering directly to an OpenGL texture buffer using libvlc_video_set_output_callbacks (VLC 4.0 beta) implementation. The way my API is setup, I use QT for GUI while VLC is implemented in an external dynamic library (dll). Since the main OpenGL context is create by QT ...

All good Remi, no worries.
What sparked the idea is that libvlc_video_setup_cb does return the pitch. It would have been nice to have the same pitch calculation as a convenience.

Thank you for your feedback Remi. Your are right but still, it seems like a common concept. In any case, based on this note from libvlc_video_set_format: For each pixels plane, the scanline pitch must be bigger than or equal to the number of bytes per pixel multiplied by the pixel width. Similarly, ...

Greeting, I'm rendering the media video data to a texture. The problem I'm having while setting libvlc_video_set_format as that the width and height are sometimes padded and we seems to have no function to get the pitch of the video. something that would complement: libvlc_video_get_size like libvlc...

Thank you for your input unidan. I've got my hands on the latest 4.0 nightly build and the libvlc_video_set_output_callbacks signature is different from the example you've mentioned. I'm on Windows 10 and the behavior seems to be awkward as the cleanup, procAdress and setup callbacks are called ever...

Thank you for your suggestion sherington. I got 4.0 and it seems to work well so far. I'll give this function I tried. Is there any example I could chew on?

Should I open a bug report?

Greetings,

Is it possible to open/playback a video file and add an audio track from an external file using libvlc 3.x?

Thank you,
