In any case, blindly apply upscaling is just wrong .. You apply it to where it is needed. Not every scene need the same treatment.

The article simply says "Trust me, just don't."

No it doesn't. It says “don't, Unless you're extremely surgical with it and know exactly what you're doing”.

Which is a sensible piece of advice.

Kinda the problem with anecdotes isn't it? :) My own anecdotal experience with VLC was that while every update fixed something, they also broke something in return - and these updates were common. This got annoying enough at some point for me to hop ships, and so I switched to mpc-hc and never looked back. I've since also tried (and keep trying) the to-me still newfangled mpv, but I'm not a fan of the GUI or the keyb…

Out of pure curiosity, what kind of things were you VLC using for, for it to break so often? I'm almost never doing anything with video, so I'm completely clueless in this field.

I don't recall my issues being media file or workload specific [0]. It was specifically just general frontend stuff I believe [1]. Although I should probably also mention that I don't remember much to begin with, other than my decidedly negative conclusion that made me switch players, and the overall personal narrative around that. It's been quite a few years if not a whole decade.

[0] Doesn't mean there weren't any, but then I was not doing anything special. Just watched anime, listened to music, streamed YouTube. Hardly an extraordinary workload for VLC, or indeed any media player in general.

[1] I remember them changing around the volume slider widget back and forth ad nauseam for example, and that becoming in some particular way defective that I cannot recall.

Nearly this entire HN comment section is upset about VLC being mentioned once and not recommended. If you can not understand why this very minor (but loud?) note was made, then you probably do not do any serious video encoding or you would know why it sucks today and is well past its prime. VLC is glorified because it was a video player that used to be amazing back in the day, but hasn't been for several years now. I…

IDK where you have been for the last decade, but Firefox has not been the better option since Chromium was made

Disliking Google Chrome proper is one thing, but Chromium is superior in every way. Rendering, features, speed, memory management

I bought a new dashcam. It generates .mp4 files. I tried to play them back with my new Roku media player, and it says invalid format. (They will play with Windows media player.)

Grump grump grumpity grump. Same experience with every dashcam I've bought over the years.

The person is asking for the better option.

VLC has always caused problems for me when seeking backwards (graphical glitches). mpv has never caused any issues in this regard.

VLC and mpv literally use the same underlying codec library. (As well as ffmpeg.)

Have you tried both? mpv is able to play high resolution HEVC videos backwards at real time by holding the "previous frame" key. VLC can't reliably jump backwards even at second intervals, forget about reverse playback.

Something I've never been able to find satisfactory information on (and unfortunately this article also declares it out of scope), is what is the actual hard on-the-wire and on-disk differences between SDR and HDR? Like yes, I know HDR = high dynamic range = bigger difference between light and dark, but what technical changes were needed to accomplish this? The way I understand it, we've got the YCbCr that is being c…

I found this explanation useful:

I'm always amazed when I see how many people are unfamiliar with VLC hate. It was notorious (to the point of it being a popular meme topic) for video artifacts, slow/buggy seeking, bloated/clumsy UI/menus, having very little format support out of the box, and buggy subtitles. I assume nowadays it's much better, since it seems popular, but its reputation will stick with me forever.

What year was this? I don't know there has ever been a normal format it doesn't support, and I think this has been the case for at least 15 years.

The only current VLC issue I encounter regularly is the subtitles one. I'm a lite video user, so I'm not sure the technical details, but some subtitle formats render black-on-black in VLC, but work fine on Plex/TV.

I've also encountered the odd "this video is corrupted" error that persists even after re-encoding. But I've never thought to troubleshoot to see if it's a VLC, and instead just get a different version.

Please elaborate on ”features”.

Does chromium have non-google sync?
