vdpau worth it for hdtv?

Hi All:

I understand how vdpau reduces cpu usage and that it will allow playing h.264 videos and such.
However, I am wondering if there is any real advantage to "upgrading" if all you do is watch ota hdtv and xvid movies? Will vdpau actually improve the picture quality? Will using a playback profile that utilizes vdpau produce a better picture than the same playback profile that does not use vdpau?

The VDPAU deinterlacers are IMHO much better then the software ones.
So yes, there will be better picture quality on interlaced content.

I would argue that it's worth it for SD as well as HD, the better quality
de-interlacers alone make it worthwhile, especially since VDPAU-capable video
cards are pretty reasonably priced.

Unless, of course, you have an AGP system, no VDPAU cards seem to be available
with that interface. Is it worthwhile to replace an entire system? That I
can't answer, of course. It is for me, but assuredly not for some others.

I have had very good luck with PCI based VDPAU Capable cards in a
couple of systems which originally had AGP cards. I also agree that
the upgrade to hardware based de-interlacing gives a much improved
benefit. I also received the benefit of my combined frontend/backend
being capable of commflagging while simultaneously playing back a
recording which, was previously not an option so I had to run a
version of the pausecommflagging script.

HTH,
Ben

In my experience, yes, massive improvement.

Before VDPAU I wasn't happy to use mythfrontend to watch TV, SD or HD, quality wasn't good enough. When the remaining gremlins are gone (which might be now looking at the update I got yesterday) and I've managed to calibrate my frontend video output I'll be using it.

> Will using a playback profile that utilizes vdpau produce a better picture than the same playback profile that does not use vdpau?

If your card is up to it then most certainly, I'm finding that you need a good bit of headroom in the VDPAU capability to achieve fluid video but when you do it's great. I have a couple of VDPAU capable cards and have tried/ borrowed another 9 or 10 cards to see what's needed to make it all run smoothly, also have a couple of 7000 series Nvidia cards which worked passably for HD with a decent core 2 duo or quad. My HDTV is mostly BBC HD but some HD Suisse, CBS, WGBH and some 35 to 140Mb/s 720p and 1080p for work.

IMHO the ION is not doing VDPAU & MythTV any favours as it's not powerful enough to make MythTV HDTV look as it should, maybe I should duck at this point..... ;-)

Lots of people on here seem to think it's the ultimate in HDTV hardware judging by the posts I've read, I would have bought one if a friend hadn't got one first and wanted me to help him set it up.

My experience of the Ion, in my case a dual Core Acer Revo R3610 has
been good so far;

1. Install Muthbuntu
2. Enable avenard repo
3. Install avenard VDPAU stuff
4. Enable VDPAU Normal as playback profile
5. Watch recordings with the CPU bearly doing anything (GPU was busy
from the warmth from the fan)

Ion, is great, as long as you do not want a heavy weight CPU. Also
great for the electric bill.

A lower end low profile ION system can be had for only $200.

It's hard to see how it could not possibly be worth it.

It's one of those rare occurences where "cheap" and "good" come together
in one device. It's like an AppleTV or Mac Mini without the hassle and or
expense.

...perhaps when everything was a little more raw, things might have been
buggier or more difficult to deal with. These days it is easy peasy and it
seems more than adequate visually. Perhaps more detailed complaints are in
order.

My install experiences with ION boxes have been like Greg's.

Ok to be fair there have been issues with MythBuntu which I put down
to ubuntu 9.10 being slightly unpolished as a release. Bleeding edge
I have no one to blame but me. For example see my email re JAMU exit
code of 1 upsetting cron.

However I am really impressed with the Revo's comindation of
cheap/small/efficient.

The only real negative for this platform (and the Windows HTPC users
seem to agree with this) is the fact that the ubiquitous web video
streaming platform (Flash) doesn't adequately support GPU video playback
acceleration on ANY platform.

I'd say cheap and fairly good, all those posts saying "it's nearly as good as my TV live" could be "it's better than my TV live".
For SD it looks great, I'm seeing glitches here and there even with SD on my friend's ION system but I understand the vdpau code is getting a major re-work for 0.23 and Nvidia seem to make improvements all the time, the odd small disaster but mostly good progress.

It seems spoilt for a ha'peth of tar that it can't do Advanced 2x for 1080i50 or i60 (the most common HDTV standard in the world), advanced 2x seems to be the de-interlacer that's as good as a decent flat screen or video processor.

Of course if the worlds broadcasters would drag themselves into the 21st century and ditch interlacing, things like mythTV would be so much easier and nicer :-)

It's certainly that, especially with minimyth net booting, very neat solution.

I keep hearing that Advanced 2x (which the Ion isn't capable of
handling) is better than Temporal 2x (which the Ion can handle, and
which I use with my 8400GS), but yours is the strongest such statement
so far!

Similar experience here (ASRock ION 330 box)... less fuzzing around than
on my previous myth install on a "larger" machine.

Full 1080p plays with maybe 10% CPU load on one of the cores, and the
picture looks very good to me on a 1920x1080 LCD via HDMI.

Does anyone have a link to a low profile VDPAU card that can output in
component? For reasons unknown to me though my TV has HDMI when I
connect it to a NVIDIA Chipset the video card doesn't even think the TV
is connected to it, so I need the component connection.

Fanless would be a bonus too.

I am not sure I would go as far as declaring live HD any better. Perhaps
if you have a really good OTA signal or a cable provider that doesn't mangle
the original signal much I could see VDPAU not keeping up in extreme cases.

I haven't found the difference to be as large as some people said.
The main benefit is the reduced CPU load. Right now there are downsides
to VDPAU on an underpowered system -- the OSD will cause stutter in the
video if you use any of the advanced deinterlacers even on 480i, at
least as of 3 weeks ago.

It also is less tolerant of errors in your recording which is an issue
with stuff recorded off the air, and even some firewire recordings which
do drop packets from time to time.

Very interesting observation; if others support this I think this is worth a

I only use SD video and I have never seen any stutter with the OSD.

I only use PVR-150 recordings and I haven't had any issues, but I
can't speak for ATSC recordings.

This corresponds to what I have seen as well. If your recordings are
clean you should be fine, but if there are errors, rather then just a
little blockiness you may see if stutter or skip.

I'm running an IONITX-A combined front/backend, which I keep hearing is
"underpowered" but I don't see any stutter with Temporal 2x
deinterlacing of 1080i when the OSD is active. Granted, it took some
tweaking to get things just right, but just about the only thing this
setup isn't doing to my satisfaction is PiP.

I should also have mentioned that I'm using Advanced 2x for 480i and
haven't seen stutter with the OSD in that case either.

If it is true that vdpau is less tolerant to errors, then that is a huge deal for me. All my tv is ota, and I get some errors due to my distance from the stations.
Can anyone else confirm this?

I would be interested in reports on this from others as well. I found that with
vdpau the errors would cause a brief flash of the entire screen to noise while it was
better handled in the regular decoders. However, I presume that this is not a hardware
thing, and that over time the nvidia driver or whatever is controlling the decoding
of the mp2 will get better at errors.

I also have noticed that vdpau is not able to play old videos I transcoded on the
system with the 8400gs over PCI bus. They are super jittery, playing just perhaps
5 frames/second. On my 220GT card on PCI-E, it plays them better, but still not
perfectly. It may be necessary to code up a mode that reverts to non-vdpau
playback for certain codecs. Or indeed, it might make sense to be able to define
a key which changes the playback method from one profile to another, so that if
you are playing a video that has lots of noise in the stream, or a codec that
vdpau is slow at, you can switch back to software encode.
