Hi everyone, I'm exploring VLC's codebase and I'm particularly interested in how pitch shifting is implemented. I've been looking through the audio filter modules, but I'm a bit confused about where exactly the pitch shifting logic is handled. Could someone point ...

... of your own setting as you want. (For different speakers and headphones) One of the few players with real speed control (after you hook tempo and pitch in settings), so no choppiness at any speed (i have it on +3 % for dance music (techno)). Some things should improve i.m.h.o., but i'll read and ...

... n; }; // VLC prepares to render a video frame. static void *lock(void *data, void **p_pixels) { struct context *c = (struct context *)data; int pitch; SDL_LockMutex(c->mutex); SDL_LockTexture(c->texture, NULL, p_pixels, &pitch); return NULL; // Picture identifier, not needed here. } // VLC ...

Can you try switching the "audio time stretching" option in settings?

I tried, but it didn’t work.

Can you try switching the "audio time stretching" option in settings?

I felt very strange while watching a music video with the iOS version of VLC, so I created a video with only one constant note, and found that the video would continue to rise in pitch as it played, and the software settings were all defaults.

... sometimes has difficulty buffering the frames properly during fast and chaotic action—like in a football game, where the camera pans across the pitch and the imagery changes rapidly. This leads to skipping during playback. While rewinding the video often resolves the issue, it's a minor inconvenience ...

Hi, I have a video, on the server side, from which I have extracted an object. For each pixel of the object, I have extracted the (x,y) coordinates of the pixel and the (Y,U,V) values for the color. I have placed the object in a JSON file as (x,y) -> (Y,U,V). Now, I want to paste the same object, on...

Disable time stretching and set the playback rate to match the desired pitch shift. You'll have to do the exponentiation manually to convert from tones to ratio.

Hello, Appear to have found a bug... I captured an API trace of vlc. apitrace trace -a egl -o vlc.trace vlc h264_4k_60fps.mp4 From the trace, it can be observed that during normal playback, VLC calls eglDestroyImageKHR to destroy the EGL images created for each frame. 7171 eglMakeCurrent(dpy = 0x7ff...

How can I adjust pitch 0.1 or 0.05 semitones?

Hi folks a newbee here.
Latest opening of the program has a changed feature that renders the program obsolete for my needs.
Is there a way to reinstate the feature of changing the speed but not the pitch?
Thank you

... When someone goes to playback speed they should be presented with a simple checkbox under the slider to keep enabled, or choose to disable the pitch-re-processing timestretch effect. It should not be hidden away in advanced. It would expose the timestretch effect to hundreds of MILLIONS of ...

oh well, after using 4.0 for a few days it seems like this specific issue is no longer present, but 4.0 has so many other issues that i'm going to have to downgrade again (lack of tooltips, scrub bar hitbox is too small, can't navigate playlist by arrow keys, can't set the playlist to full width, pl...

I gave VLC 4.0 a try and I didn't get to the point of figuring out whether this is still a problem because I was too distracted by the playlist view. Is it impossible to get the playlist to take up the whole upper part of the window like it used to in prior versions? None of my audio has cover art a...

VLC 4.0 preversions

Those exist? I'll give them a try, thanks. (Also didn't realize you were a dev.)

I meant that it would take at least a major release, and there hasn't been one since I wrote that.

Feel free to try VLC 4.0 preversions

This is a well known problem, that will take some more years to be fixed. Can confirm it has been years and I'm still experiencing this issue. I've been experiencing it on and off since 2.2.4 on macOS. It's now been happening for the past couple days on 3.0.19 Vetinari on Windows and I seriously ca...

... don’t need to have music stored in 5/6 Pcs in all the classrooms. I only miss the chance to change the music tempo (change just the speed, not the pitch). There is a speed changer, but the range (from 0.25 to 8.00) is not useful. It would be very helpful to have the same function (speed changer) ...

In VLC desktop, you use Tools > Filters > Advanced > Pitch, right? If so, it sadly not available in the Android version.

I'm starting to wonder if the adjust pitch setting offers too little, because of its limitations (you can only select x0.3, x0.5, x0.8, etc.) I have my VLC set-up so whenever I want to, I can switch between normal pitch and PAL pitch easily, ...

... get dark mode with changes to the original UI which are done by every theme. All I want is to have the same old VLC standard interface but with a pitch black playlist and everything else just toned down - and as a standard option built in the regular preferences. I also know this in on the wishlist ...

... around 3:00. I'm mentioning that just in case as I do not know and haven't tested if the lenght of the clip has any effect on this behaviour. The pitch offset from the origin peaks at -25 and 23 cents. https://imageupload.io/ib/1sLsNbu2lsyksWM_1697286096.png
