MediaPortal uses EVR with 3 input pins-> drops 50% of all frames on interlaced stuff

[krusty2die4]

tested now different refreshrates and have a partially success, although only on 720p@50:


1920x1080px32@60:

progressive x264 23.976fps material 720 and 1080:

----Best results in all players


interlaced h.264 25.0fps material 1080 (the TV-Recordings):

----micro-stutter in ZoomPlayer / EVR reports no droped frames

----50% droped frames in MP as usual



1920x1080px32@50:

progressive x264 23.976fps material 720 and 1080:

----Choppy and stutters in all players


interlaced h.264 25.0fps material 1080 (the TV-Recordings):

----best result in Zoomplayer

----35% droped frames in MP (better, but not watchable)


1920x1080i32@29:

interlaced h.264 25.0fps material 1080 (the TV-Recordings):

----10% droped frames in MP - better than progressive ScreenRes@50, but also not perfect




1280x720px32@50:

progressive x264 23.976fps material 720 and 1080:

----Choppy and stutters in all players


interlaced h.264 25.0fps material 1080 (the TV-Recordings):

----again best result in Zoomplayer

----but also only 0,3-1% droped frames in MP




So as a workaround watching lifeTV not bad. Doesn´t really make sence to me that MP plays a 1080i source best @720p50 while Zplayer has best results @1080p50, but I can live with that for the moment although i´d rather like to watch FullRes than HD ready...
I will stick to the ZoomPlayer as an external player for vids and recordings until bugs are fixed because with that player i have the least issues with DXVA and I can keep FullRes @alternating 50 or 60Hz (depending on Vidstream) for the most time except Live-HDTV.
But i´m definately interested in not using external players at all in the future...

attached screenshots:
snap #1: Recording BattleStar @ ScreenRes 720p50 with 1% droped frames
snap #2: LiveTV Battlestar @ScreenRes 720p50 with 0,3% droped frames
snap #3: LiveTV Battlestar @ScreenRes 1080p50 with 35% droped frames
snap #4: Filtergraph from Zplayer how it connects AvP2 (1920x800p) to EVR
snap #5: Filtergraph from Zplayer how it connnects Battlestar (1920x1080i). Here it´s remarkable that the PowerDVD8 H264/AVC crops the vertical pixel from 1080 to 1088, decreases from 24 to 12 Bit and hands that over to EVR...no idea why...picture looks perfect.

Any chance fixing an eventual bug in MP / EVR allocator in the next SVN? I´d be a dedicated tester

Yes! I'm getting lots of dropped frames with hw. acc. (PowerDVD codec) and EVR in MediaPortal. This seems to happen when playing mkv HD files, but also DVD (files from my harddisk).

When turning EVR off, no dropped frames anymore and everything works perfect ... This is not the case in other players as far as I can see.

Having the same issue, with HDTV (1080i). EVR drops frames constantly, while VMR (all modes) gives good framerates, with the PowerDVD codec. 1080P content (Mkv files) are beiing displayed correctly, on both renderers.

Also having the same issue with DXVA turned on with Powerdvd decoder. Especially with DVDs. But I see some improvement with Catalyst 8.7. Used to have 8.3 earlier.

Regarding Live HDTV (720P h.264) I have no such problem anymore with HDTV, so now I only have the problem with DVD.

DVD´s (well, dvd files from my harddisk, haven't tried a real DVD yet) drop frames here too (Ctrl + 1 in MP), but I have a NVidia card and you apparantly have a ATI card, so it can't be related to a specific card..., it has to be a bug in MP in my opinion.

I'm facing the same problems(with PDVD 8 + ATI 8.5):
- 1080p50 no problem, no jitter or drops
- 720p50 no problem, no jitter or drops
- 1080i50 is horrible, jitter and really bad horizontal pans

Maybe it's 8.5 but I'm unable to get EVR working with 8.8

1080i requires much more GPU power than the 1080p as the deinterlacing is pretty costy operation.

Agree, but:
- I have a HD2600 + PDVD8 (with the subtitle filter turned off)
- A X2 6000+ CPU which should do the job without any issues

This topic is really interesting.

This is what happens during H.264 1080i deinterlacing:
- PowerDVD 8 is using DXVA (confirmed using Graphedit)
- According to CCC the GPU is utililized to only 16%
- CPU utili is approx 20%

What I see in MP in EVR mode is 15-22fps but no dropped frames.

What I've tried:
- Several ATI drivers, no difference
- Different PowerDVD deinterlacing settings
- Different ATI CCC deinterlacing settings
- Tried to use bob on both PDVD and CCC, read that on a forum
- Turned of Avivo HD decoding using a registry setting(DXVA_NOHDDECODE=1) in order to give all GPU HW resources to the deinterlacing
- Tried the "32C" deinterlacing in PDVD aka "Vector Adaptive"

Which led to:
- No difference

The funny things is that CoreAVC 1.8.0 doesn't drop frame and produces a silk clean and smooth picture no matter what I throw at it.

(PowerDVD works brilliantly on 720p and 1080p content)

So what does this mean?

a) My ATI HD2600 Pro 512M is crap
b) PowerDVD can't do 1080i deinterlacing, bug?
c) ATI are full of crap for touting their "Vector Adaptive" deinterlacing of 1080i content

If a is correct, what should I buy? Maybe I should give my 8600GT a second try.
