webp and AV1 support in SeaMonkey

[frg]

Since yesterday 2.53.5b1 pre has webp support enabled.
Bill ported AV1 support to 2.57. It will be enabled in todays alpha build.

Please test both and let us know if it works. AV1 for 2.53.x and webp for 2.57 will be next.

frg,

Works just fine with limited testing here 32 bit using 2.53.5b1 pre:

P.S. Does not work with SeaMonkey 2.57 alpha 1 - 20200902120001, 64 bit.

Thanks to Bill AV1 support is now also in the latest 2.53.5b1 pre build.
2.57 now got webp support too.

Please test.

Having a bear of a time finding good AV1 sample files, but no troubles playing back ".webm" video in the 64-bit Bill build from the 14th.
BTW, not sure if you really only wanted ".webp" images, but they are kinda related... in any case, both of these display/play fine on this latest 64-bit 2.53.5b1pre build.
As soon as 2.57 has a believable email story, I will be all over it - and even willing to switch. If we *really* need some testing on 2.57 before then, can I run 2.57 using my 2.53 profile without harm to said profile? So that even if I can't use email, I at least wouldn't have to worry about trashing my profile will doing limited testing?

can I run 2.57 using my 2.53 profile without harm to said profile?

Don't know, but I would not.

Why not simply make a copy of your Profile, call it Profile_FOR_2.57Test, & create a shortcut to 2.57 that opens that (new) Profile (using the -Profile switch) directly.
Then you can do anything you want to it without it affecting existing Profiles.

I just made one, GO.bat:

Code: Select all

cmd /c   start   C:\SM253.5b1\seamonkey.exe  -profile   "C:\USERS\TEST - WITH sessionrestore"

@therube, thanks for reminding me of the tools at my disposal - I could actually even use the "Profile Manager" that is part of SM!

@frg, I found some AV1 links that weren't dead-ends... so, yes, on the above-mentioned Win 10 Pro 2004 box with 64-bit 2.53.5b1pre, various resolutions of AV1 files play - if it matters, they were all in webm containers (I thought they might be in mp4s?).

But what I found "interesting" was that, with both SM *and* verifying the same files with a current VLC, that my GPU wasn't being touched at all - is this because only software-based decoding and playback are available for AV1, or that this was just the easiest way to get this capability, or is this just because the open source world has not yet produced the infrastructure for AV1 that takes advantage of GPUs (yet)?

Not complaining in any way! I think is amazing that were are only in 2020, and now can handle random multimedia playback directly in open source browsers - no broken / scary / insecure players needed.

I really didn't look at the specifics. A lot of drivers are broken and won't activate hardware decoding. Aslo depends on your card. I also doubt that many cards yet implement decoding av1 in hardware. I don't see cpu spikes here but ymmv.

Here are a few samples:

Not all AV1 and not all of them play yet.

More or less the official test:
