#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!

Now that #Dolby has launched a #patent lawsuit over #AV1, unless I'm mistaken we're about to have a repeat of the #Unisys #GIF patent situation where all #browser⁠s must remove support for widely-used image and video formats, namely AV1, #AVIF, #WebP, #WebM, #VP8, and #VP9.

This is really bad. The only other widely supported video codec is #MPEG-4 (which is also patented) and the only other widely supported lossy image format is #JPEG (which is rather inefficient).

What do we do?

Does anyone know how to convert a #webm file to #mp4 using #ffmpeg?

.. .. I know what you're thinking: "that's super easy, just run ffmpeg -i input.webm output.mp4"

And yeah, it's that easy, in roughly 50% of cases. Specifically when your video's height *happens to be* divisible by 2. But if your height *happens to be* an odd number, hooo boy, ffmpeg does not get happy.

Can't it just automatically chop off the last row of pixels???

@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?

Someone NEEDS to tech-splain to me, WHY exactly it is preferable to

👉 #transcode a 198.8 KiB #GIF #animation into a larger not-GIF format
👉 upload a 230KiB #webm #video, and not suffer improper frame-pacing
👉 misrepresent lots of formats, that aren't GIF(Graphics Interchange Format)

As a #Twitter #Refugee, i find the severe LACK of #Truth in the #Mastodon #Code really rather disturbing! 🤬

Things MUST be represented as they ARE! We "elder-millennials", demand proper "truth"! ✊🤬

🧵 3/n It wörks! 🤣

EDIT2: this #webm video should make things more obvious - the previous #GIF didn't blink properly.

edit: this is "lspci -tv", before and after - on a #Manjaro box, Minisforum UM780XTX, Zen4 Ryzen 7840HS

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
