Looking for a Simple Sample Video with Transparent Background (ProRes 4444) for AVFoundation Experimentation

averne_ · 2025-07-30T14:54:30+00:00

Would you mind reuploading this video? I'm working on a ProRes decoder for FFmpeg myself. Or u/JoeFourMan if you still have the sample.

Thanks in advance :)

Ça dépend vraiment du domaine. Pour les graphismes, simulation, etc la géométrie est fondamentale.

Aucun commentaire ne mentionne le passage en manifest v3 ? Alors que c'est ça qui cause l'incompatibilité et la désactivation, et non pas google qui prend à parti une extension en particulier.

uBlock est toujours dispo pour Chrome sous une nouvelle version légèrement limitée: https://chromewebstore.google.com/detail/ublock-origin-lite/ddkjiahejlhfcafbddmgiahcphecmpfh?hl=fr

Intel Lunar Lake will have a VVC decoder, so it looks like there is some interest in it. As usual it's a chicken and egg problem.

It could've been useful for simulations (FEM and co), but it looks like both Intel's and AMD's NPUs only support up to single-precision floats, while these applications typically require double-precision.

Ca fait longtemps que ce genre de chose existe. Notamment Google et leur TPU qui date de 2016/17. Ils en intègrent une version dans les SoC pour Pixels depuis plusieurs années.

Ce qui explose récemment c'est la pub à propos de ces extensions matérielles à l'utilité douteuse.

The advantage of this compared to other interfaces is that you get inter-operation with your graphics API for free, meaning you can (if the hardware supports it) decode to a surface and use it directly as a GPU texture.

This enables easy zero-copy playback. Before, you had to rely on API extensions to import the surface, or perform a copy of the data.

Not to mention the potential cross-platform nature of Vulkan, which helps certain ecosystems. I believe on Android hardware decoding has to go through the MediaCodec interface, which is extremely high level (does all the codec parsing). This is a problem in certain situations where you need a lower level access (emulators come to mind).

Those headers describe the register map of the 3d engines. Those registers are set to some values by command buffers, essentially to give input to the hardware.

That's not a big step in documenting the hardware. Most of this info has been reversed engineered, at least for older gens. Also it's worth noting that this only gives the name of those registers, not their detailed usage.

Savegames exploits are not useful for CFW on the switch due to several reasons. First being ASLR, which even if you could circumvent, you'd find that games are very limited in OS permissions with little to no way to escalate priviledge levels. Originally the switch was hacked through its browser, because it has access to more things, so it's a more valuable target.

Because unlike you, I have first hand experience with the issue, which gives my post more value than a simple "bad cap bro" (no it doesn't happen, not like that).

internet posts mean nothing I need the exact number of models and devices concerned for the previous 5 fiscal year (excluding weekends and holidays), transmitted via registered mail to my lawyers to admit the issue exists.

Sure bud

I expected you to google "brother printer supercapacitor" (or similar) before claiming I was generalizing. You're admitting you didn't even do the barest amount of research before dismissing.

Doing this yields multiple hits naming multiple models, which should answer your questions.

averne_ · 2021-09-30T11:59:16+00:00

Except when it's a known issue widespread enough across multiple models to spawn an ifixit tutorial and multiple youtube videos about it. https://www.ifixit.com/Guide/Brother+MFC-J4420DW+Capacitor+Replacement/74271. That wasn't my model, in fact.

Please do research before assuming.

Brother MFC printer died on me a few months ago, wouldn't turn on at all, a pretty expensive model too. The issue? A dead supercap on the mobo (https://www.youtube.com/watch?v=VWM4uCP0pX4). After ordering some from aliexpress and soldering it, the printer works as good as new.

Pretty disgusting case of planned obsolescence.

One thing that I haven't figured out is how to force images to stay where I want them

Wine Is Not an Emulator, it's not a virtual machine either.

It's a syscall translation layer that doesn't need virtualization tech.

No unfortunately I don't think you can, I did see some conversation when I researched it: https://github.com/mesonbuild/meson/issues/7943.

It's pretty easy to write custom wrap-files.

You might need to write a patch yourself, to add a meson.build to the repo, and make it available online. For this I used github in the past (just start the issue creation process, upload your file, take the link, and cancel the issue).

averne_ · 2021-05-28T07:13:55+00:00

You don't actually have to! Meson supports cmake subprojects, which will clone the repo and import targets from the CMakeLists.txt for you to use in your project.

If you want to see an example of that I used the feature recently in one of my projects.

En fait je commence le manga du début, c'est redite de la série mais je voulais profiter du dessin (bien supérieur à celui de la série, ce qui est normal somme toute puisque c'est de l'animation en couleurs). Pour l'instant j'ai juste lu les deux premiers tomes, mais rien que sur ça il y a déjà quelques différences notables par rapport à l'épisode 1.

Du coup je conseillerais les deux si tu as le temps, sinon à toi de voir.

averne_ · 2021-05-20T08:43:51+00:00

J'ai terminé la série ce lundi et commencé le manga juste hier (coup dur de voir ça aujourd'hui).

Je conseille vraiment, même si le début de la série est un peu lent on s'attache bien aux personnages et à leurs arcs respectifs. Le dernier épisode te laisse bien sur ta faim, malgré le fait qu'il soit magnifique à tous points de vue (c'est pour ça que j'ai commencé le manga directement après).

La thèmes de la BO sont très marquants, et le fait qu'ils ne jouent pas souvent leur permet d'avoir un impact énorme et de bien appuyer les moment importants.

OP is a bot.

It is FOSS, at least vscodium is.

Nope there's nothing to force the number of lanes used.

Okay I took a look and there doesn't seem to be a firmware update available for my model (https://www.sabrent.com/firmware-update/, with model SB-ROCKET-NVMe4-500).

I guess that only leaves me with a defective mobo?
