Any altivec experts? (H.264 codec)

@Hans & LiveForIt

Yes I know it's a lot of work. It always is But there is no device in the world today that doesn't use HW decoding for mainly h264. All phones, tablets and laptops do HW decoding. My Surface actually refuse to play any video formats it doesn't have HW for! I can't play plain mpeg2 for example.

Is it really that secret and exotic to make it a reality? We only need h264 and we only need it for Radeon.

But Hans, what do you mean by "there's a lot of software that needs to be ported/written/updated in order to do so"? There is only mplayer that needs this primarily, with support in your Radeon driver probably.

I have a couple of green videos with, what I believe is the latest version. One version from last year that only has the comp driver works without being green in those videos. Otherwise it seems quite bug free, yes

Maybe I missed a new version very recently?

I'm not sure what you're getting at. I've already said that it is possible, but a very large amount of work. I wouldn't call it "secret and exotic" at all (although there is no documentation available; only source-code).

I guess that I should have written "a lot of code that..." Anyway, here's the list (AFAIK):
- MPlayer
- Libavcodec (okay, it's part of MPlayer, but it specifically needs an update, and we'd also like other programs like DvPlayer to have access).
- VDPAU
- Gallium3D
- RadeonHD.chip (needs updating to give access)

Yeah... Guess I'm just desperately dreaming a little here... Too bad everything modern should be so damn complicated and hard to implement and use. And of course, everything has to be secret (no docs).

Doesn't get less frustrating by me having run out of time an enthusiasm for coding a couple of years ago, after nearly 20 years of hobby-coding...

Still searching why I am experiencing some freezes when using MPlayer-altivec
http://www.amigans.net/modules/xforum ... t_id=99453#forumpost99453

Is it normal, when video/MPlayer is paused, that Snoopy events loops on

Thank you

don't mix this things up, libavcodec used in mplayer is part FFMPEG package, so when you take the latest FFMPEG you have the latest libavcodec, everything is statically linked.

On DvPlayer changes was done so it might be sold as a commercial product, the way it was done, was by removing codecs and things that have open source license. so libavcodec was rewritten as an Amiga library.

There is no access to speak of, the latest avcodecs are found here: https://www.ffmpeg.org/, just download it, and rewrite it for DvPlayer, Mplayer does not require a rewrite of libavcodec because it open source and in compliance with the open source software license.

We have version of mplayer with FFMPEG 2-7-1, FFMPEG 2-5, FFMPEG 2-6-3, this makes mplayer just a few months behind the official builds, keeping it up latest build be too much work. and if you also won't rewrite avcodec for AmigaOS for etch version, then that work load multiply.

@zzd10h

yes.. It looks silly but should not be a problem.

IF you like to look for bugs look here.

ok ,thx
