Realtime FW DVcam grab and display on MacMiniG4/MorphOS
« on: October 04, 2010, 08:55:45 AM »
Guillaume "Yomgui" Roguez of the Blender MorphOS Port fame has been busy working on FireWire stack for MorphOS (Helios). It's progressing rather well:

Here I've upgraded my get61883 code with a MUI gui and a vlayer display. I've integrated also FFMPEG DV decoder.

So what your're watching in this video is a realtime decoding and displaying of the firewire DV stream from my DV cam.
And for sure: Helios FW stack powered ;-)

The new version doing video cams isn't out yet I think, but version supporting block devices such as HDDs and Macs in Target Disk Mode is here:

Nice!

It's great to see some end-user functions coming to fruition on Helios.
I read that Yomgui was working on isochronous reads - I see he has got things working nicely.

Webcam functionality on MorphOS machine would certainly be nice to have :-)
Mac Mini G4 (1.5GHz, 64MB VRam, 1GB Ram): MorphOS 3.6
Powerbook 5.8 (15", 1.67GHz, 128MB VRam, 1GB Ram): MorphOS 3.8.

Too bad that the only camera I have around that has FW on it has lower resolution and less camera capabilities than my cellphone :D

Or to put it differently, this would have been nice 5 years ago when FW still was relevant.

Yeah, I wish the MorphOS team and MorphOS developers would stop focusing on dead-end hardware.  Firewire was never a big deal and it fell into even greater obscurity after USB2.0  became widespread.  MorphOS would be better served by having better driver support for video cards and USB2.0.  Or even better, port the OS to an architecture that isn't a dead-end.

Dead-end OS on dead-end hardware - why not? :)

Doesn't Poseidon support USB 2.0 ?

Read it as "better (driver support for video cards and USB2.0)" and not as "(better driver support for video cards) and (USB2.0)"

Btw - USB3 is here now.

Thanks Kolla.  That's exactly what I meant to say.

I appreciate that you have an opinion, but consider the possibility that that's all it is - your opinion.
While I'm sure that there are some that would agree with you, I'm not one of them.
If you want an X86 Amiga like OS, use AROS. The MorphOS development team has repeatedly stated that for the foreseeable future they're staying with PPC systems and not considering a port to X86 architecture.

If PPCs are dead why are Applied Micro and Freescale still developing new processors? Yes PCs have moved on from these processors, but I like having something different.

Right now, the only thing that really differentiates Apple desktops is their OS and I don't care for it.

MorphOS developers may listen to  your opinion, but in the end they're going to continue to advance in the same direction they always have - focused on what they'd like to see in new releases.
You don't have to use or pay for the OS. Don't like it? Don't use it.

FireWire (even FW 400, never mind 800) craps all over USB 2.0 from a great height.  Far from being dead-end, FireWire 3200 does the same to USB 3.0. In addition to being significantly faster, it's also backwards-compatible with the older standard, unlike USB 3.0 you can just plug a new FW 3200 device into an older FW 800 port and get the faster speed.

Sorry, but Firewire is a professional standard used on prosumer and professional level video cameras, such as MiniDV and HDV cameras.

It's also used for pro-level musical recording hardware - i.e. audio interfaces, control interfaces, etc. in both home and high end professional studios.

It's USB that's seen as a lower end interface.  Useful, yes and common, but not as capable as firewire.

Great news, nice to see Helios is progressing nicely. Firewire is a nice professional standard and should be support.

@Iggy

Nowhere in my post did I say ANYTHING about x86 or even hint at a direction that I think the developers should take regarding a new processor for MorphOS.  Nor did I mention AROS or any other operating system.  It isn't opinion that PPC processors and all the Macs now running MorphOS are a dead end.  It is FACT.  They are no longer manufactured.  PPC is dead.  Get over it.  As for not using MOS, I don't use it any longer.  It's overpriced, runs on VERY outdated hardware and doesn't have any productivity software that meets my needs.  My PegII is just an expensive paper weight these days.


@ral-clan

As for Firewire being a professional standard, that was 10 years ago and even Apple is dropping support for it.  Even if this new Firewire stack gets completed, you won't see any audio/video professionals running out to buy an ancient Mac running MorphOS and doing any audio/video editing.  Why?  Because decent audio/video editing software doesn't exist for MOS and even if it did, why would they handicap themselves by using hardware that's several years old and several orders of magnitude slower than anything else on the market?

It seems that Final Cut Studio 3 still loves that Firewire.

Great.  Maybe you and the MOS devs can port it to PPC Macs for MOS?
