EDIT: Okay, solved it! 🥳 It turns out that the solution was:
Tools > Preferences > Input > Hardware acceleration to "off", then restart VLC
The graphics card was somehow messing up VLC's playback it seems, so switching it off in VLC made it work.
-----------------------------
Any VLC experts here?
I have VLC on a Linux Mint PC and it won't play WEBM video files properly, there's sound but a blank screen.
The same files on the same PC play totally fine in Celluloid, but not in VLC. Any ideas why VLC is having problems?

#TIL from building a web audio player (for the mixes):
#Safari's #opus support is still quirky. With a #webm container, playback works but AnalyserNodes won't receive anything to compute frequency data with. With #ogg, `getByteFrequencyData()` works, but the audio element calculates the wrong duration, prob. b/c it always assumes CBR. Also if you build the audio pipeline before the first user interaction in Safari, nothing will get routed to the speakers
But still, the #WebAudioAPI is awesome!

@dalias Say you want the public to benefit from a video codec that's usable by free software in countries where MPEG-LA members hold patents. Would there have been a better way to go about this than how Google released WebM using On2's TrueMotion VP8?

When's #Mastodon gonna roll out support for #WebP animations? It should also start handling video formats like #WebM or #MKV, a social for nerds and geeks oughta be one of the first to jump on that, especially since they're open formats with no royalties. #opensource #socialmedia

Well, I did it. I deleted my #Loops account, I am off that #Fediverse platform. There is no #WebBroswer option to use it. Uploading #Webm and #MKV videos is a no-go, and it failed to optimize the #mp4 from my phone.
-
I just made a #WebM video for #loops it is 1.8mb down from the 8.6 mb when it was a #MKV. It has been several minutes at 0% of optimizing the video. Hahaha what!? Wait... It was taking to long so I tried the mkv file and that is stuck. Does loops only do #Mp4 files? That is too bad and kinda dumb. Looks like I will be dropping loops from my #fediverse profile :angery:

Just completed a #Transcode of around 30 minutes of .webm vid+aud into h.265 (aka #HEVC).Took 8 hours.
And the computer's fan did a lot of whirring.
Getting a format that the TV wil play without #Transcoding seems necessary.

If #tumblr had to see it then so do you. But you get an actual webm video, rather than four GIFs and an MP3. Edited/rendered with kdenlive, where I added English subtitles. #tapir #belize #gif #mp3 #webm #australia #WorldTapirDay #kdenlive

Please help, 🙏 How can I compress a video that is basically static slides (instantaneous transitions) with a voice over, so duplicated frames do not occupy any space? I tried using `mpdecimate` on the FFMPEG command but it completely sets audio and video out of sync.
Yes. I really am a compression masochist. I love it when the same information occupies the minimal space possible.

CW: NSFW sissy stuff
jus testing 2 see if i want to upload more here. i used exist on another instance uploading porn i liked and rilly enjoyed it! that said lots of other people didnt. lemme no if u think we need more people uploading random smut.
i like to share what i have. i try to credit when i can and hashtag kinks for filtering. an if its u in a vid and want it down let me know!

#38c3 recordings and indeed pretty much all https://media.ccc.de/ content is just fine at 75% smaller download sizes: #webM & lower resolution. Unless a presentation contains lots of source code ¯\_(ツ)_/¯
Thank you #c3voc for offering that, and for probably having spent many hours improving the conversion settings 🤩

I don't know how people usually pronounce it, but I propose to treat the B in WEBM and WEBP as silent, pronouncing it like "wem" and "wep". The B doesn't add any necessary auditory information but makes it harder to pronounce. #webm #webp #pronunciation

Aww damn, man! @yusef
super awesome to find you!i'm so behind on stuff! damn stupid LAN... finally got that "working". gotta setup the nginx etc. but really excited that i caught someone's attention about that FINALLY!
thank you!
https://statecollegeguitarlessons.com/adb/aeolean.webm@zombiewarrior how come you never mentioned about that? I guess #UiUX not really your bag, baby?

Which one did i try? Aww.. i was trying to do that song, "In the end" by Linkin Park.

Sitting here watching a #Kurzgesagt #video and it has me wondering....
Their videos are basically #vector #graphics and vector drawings, no doubt rendered to an #MP4 video or something similar (#WebM, etc.)
Think about how much bandwidth would be saved if we could actually stream vector #animations!
In other words, we need to create and/ or bring back an open-source version of Adobe (Macromedia) #Flash! -
The last days i wanted to deliver a video (as a static video file) on my webserver to friends. Personally i mostly use #vp9 / #opus codec in #webm container. This worked everywhere but on #iOS. I do not have an Iphone so i could not test it before.
I tried to get vp9 working (and ask friends to test again), but couldn't get it work, though there are many announcements that Safari will supports it (in 2020). Then i tried #h265 / #hvec in mp4 container because Iphones use this for encoding their recorded videos. So i thought this must work. But also that did not work.
Afterwards i found this guide who tells that #Safari only accepts #h264 static video files. Everything else has to be delivered by #HLS. Does anyone knows why? Is there a technical reason why accepting h265 videos in hls but not in static file? https://developer.apple.com/documentation/webkit/delivering_video_content_for_safari
During my research i found many different arguments why iPhones did not support vp9 (due to missing hardware decoders or because it increases code complexity). I can understand that but i can not tell you if this is the real reason (or just because its a standard of Google). But on the otherside i found information that Apple supports VP9 with HLS. but does not say this official.
PS: I know i could just use standard h264 encoding, but i wanted to have small video size and i thought that ios will accecpt at least any format that is newer than h264.

@brion hmm. My video playback is frozen in MacPro Intel for vp9.
Seems it is using native playback, but not actually playing. I guess Apple broke it again :/> $1.canPlayType( 'video/webm; codecs="opus,vp9"' );
< "probably"Decodes first frame, then freezes playback.

Google's Threat Analysis Group has uncovered a high-severity heap buffer overflow vulnerability in the libvpx library, specifically in its VP8 encoding component, registered as CVE-2023-5217. This vulnerability allows arbitrary code execution, posing a significant threat. The exploit is known to exist in the wild and affects various applications and services that use the libvpx library for VP8 and VP9 video encoding and decoding, including WebRTC platforms, streaming services, and multimedia applications relying on FFmpeg. Developers and IT administrators using libvpx should upgrade to a patched version, and general users should keep their software updated as vendors release patches. The vulnerability extends beyond Google Chrome, impacting Mozilla Firefox and other softwares.

Why is a transparent video still so god damned hard? Most painful is Apple's HEVC, because Safari only supports that. Creating one requires either a Mac with Videotoolbox or a Final Cut Pro Compressor. Old venerable FFMPEG can't produce HEVC with transparency.
While Webm is excellent for Android and Google Chrome, it is still not without issues, it sometimes changes colors just a little bit, and some Androids show matte edges (not on all).
