Hi Owlsroost

Version 0020 is working well for me for xvid videos without reclock, but I have lot of frame drops on TV with 720p (H.264) or 576i (MPEG2) material at 50Hz. Do you have an idea why?

hirscho

Does this happen with the standard RC4 dll or any of my older dlls ?

Can you attach a screen capture with the render stats on screen please ?

Very interesting finding. I tried the registry fix - it does seem to reduce the problem but not entirely (could also be a placebo).

However - after stopping the playback and restarting - the video runs fluid again. There should be a way to bypass that behaviour in Windows, so the OS should think "Everything is OK - I must not slow down the framerate".

My guess is that a little pause after a refreshrate change should be done before the actual videoplay starts. My TV also needs about 2 seconds to change the refreshrate itself - so a little delay in this process should not "hurt". I am no programmer but I am able to compile Mediaportal. Could anyone give me a hint where I can add this delay in the code after a refreshrate change has been made?

The right place is probably in the Core -> Player source code, but no idea exactly where...

Or to make a more intelligent approach:
As Mediaportal always measures the display cycle it should delay the starting of the entire videoplayback until the measured display cycle matches the video fps.

MP doesn't measure display cycle as standard - it's my version of dshowhelper that does (to get around the problem that Vista doesn't report accurate refresh rates - just integer numbers).

You can try with reclock and its internal scripting system as alternative to Media Portal disabling that one.

Great Work Tony, today i've tried the v19 dll with MP rc3...and it works awesome.
Red line is always totally FLAT, just in 24p BD and 720p, 1080p mkv i get yellow and green lines slightly spiked..... almost no frame loss.
the interesting part is finally the powerdvd10 codec is working perfect, more flat lines in HDTV.
All these results are made with Catalyst 10.6.
As soon as possible i'll do a more long tests and post complete results.
byeeeeeeeee

Hi!

i made more deep testing, the results are genarally good but not good as at the first sight

if you need more information or something else feel free to ask me what you need to improve your dll

All the images are tiny, unusable png files (180 x 54 pixels)....

Also I need the evr.log files for the bad stuttering cases to really see what's happening.

If you remove the .th.png from the link to the file and replace it with just .png you'll get the full size image.

sorry my mistake,

now the links are ok .

asap i'll post evr.logs.

thanks

I think this problems are not related to dshowhelper DLL but to your particular hardware/software configuration.

You have the same ATI 4670 as me and I do not experience any frame loss in HDTV nor SD.

I suggest you to check your system latency with this tool first: DPC Latency Checker

HDTV 1080i 50i:50hz very nice , but sometimes (30,40 sec or more) i get or 1 frame loss or a microstutter (the most of those are not noticeable)

I get that with the M$ codec, if I switch to using MPCVideoDec.ax (latest) this goes away.

roby have you read carefully my post ?

"NOt noticeable" what does it means to you ?

and more don't you think if i have some HW related problem i got the same problem with the original dll ?

on my system the original dll works perfect on TV . And obviously the latency is the first thing i've checked after the complete reinstall of the system.

So i think you have some hw related problem ....... why don't let just tony talk about his dll ??

i start to be p****d off about this kind of unuseful crappy comments about hw related problem...... i think you must know me pretty well to keep for you that s**t.

Stiamo calmi dai che non è il caso. Robyf voleva solo aiutare. Qui sul forum ci possono essere niubbisimi o super esperti e non si può sapere con chi si ha a che fare. Qui non si parla di problemi hw si tratta sempre del fatto che chi sviluppa non può produrre codice compatibile con tutti gli hw disponibili . è un dato di fatto inevitabile.

in english: I'm trying to stop right now some kind of misunderstanding of these italians and going on.
