1810tz vs Silverlight Movie = stutter :(

Hi,

does anyone know if there's any possibility to change options like DXVA and hardware acceleration on microsoft silverlight?

I'm watching the US open on Eurosport online streaming but even though the quality isn't really good there, the picture is always stuttering, every second or so. It really suckz! It's not a CPU problem, utilisation is aroudn 40-50%. Looks to me like there's a problem with DXVA support?!

Even my old computer plays it smoothly ((

 

Silverlight IS a ressource hog.
Go here: Microsoft WorldWide Telescope Web Client and chose one of the "guided tours". On your 1810, you'll get something like 70% CPU load.
On my older desktop (Athlon64 3000+, 2 GB RAM), I get 99% CPU load

wow, that's a really cool website!! thanks!
But I think there still is a problem with video playing because it's pretty much the same as it was with youtube until I discovered disabling the hardware acceleration in flash. Before, the CPU load was very low but it was lagging! After disabling it, it was fluent.
So I think it's pretty much the same with silverlight only I haven't found an option to disable hardware acc.

try this livestream: Demo: IIS Smooth Streaming | Features | Microsoft Silverlight do you have stuttering and block-building (deblocking errors) especially when the movies of the olympic games are shown? ironically the most stutter appeared when they were talking about "avoiding video stutter"

please tell me your results!

 

Yes, I have. But I am not sure if these artifacts are from the source material. Playback looked smooth for me, and CPU load was only at ~30 +/-5%.

The trailers in the "on demand" section seem fine (tried the Robin Hood).

Edit: tried the first video with my Dell Vostro (see signature) which is much more powerful - no difference. I am inclined to think these "blck artifacts" are purpose.

hey, I have an update: I think stuttering has something to do with the HDMI connection to my big LCD. On the integrated display it's okay, with HDMI to the FullHD-LCD, even a low-quality stream from eurosport is stuttering! the microsoft videos as well.
Do you know if there is any solution for that? Maybe you have an extern LCD as well and can try it there...

it's terrible, having a fullHD LCD, an HD stream, enough power on the notebook for that and then HDMI is destroying everything!

 

Maybe it's the HDMI cable. I know next-to-nothing about HDMI, but have read that often getting a higher-rated cable sorts out some problems.

 

I don't think so because:
when I use "clone desktop", so that the picture is shown at the integrated display and in the same resolution on the LCD as well, there is no lagging. But the image is smaller then because the aspect ratio doesn't fit.
I now think that it's a problem of calculating the full screen resolution on the LCD -but the CPU usage isn't really maxed that's the weird thing.

 

Okay. This is something else then. I don't have an external display I can connect to my laptop.

btw: what happens if you connect your laptop via VGA? Same problem?

I almost forgot about this issue because the USopen are over now

But still I'm thinking about this issue as it also affects youtube 1080p movies and some other 1080p movies.

I tried connecting it with VGA but it's the same problem. But what is surprising: the picture quality (desktop, written text...) is the same with it, even though my LCD has FullHD resolution! I didn't expect that.

So to sum up: I think the graphics driver has problems upscaling this high resolution somehow...weirdly only when the input resolution already IS FullHD. I don't get it.

 

Just a note, on my DV2 (HD3410 - a glorified HD3200), there was stuttering playing 1080p BluRay (Hurt Locker, iirc).

I think the decoding ASIC just isn't upto the task, despire that ATi says. My Intel GMA 4500MHD (I have two, one in a 4810TZ Timeline, and one in an Alienware m11x) plays 1080p perfectly (I now use the Timline to play BluRay, since my DV2 isn't upto the task), doesn't exhibit stuttering in that IIS Smooth Streaming page.

EDIT: approx 38% CPU usage across both cores of my stock SU7300 (m11x) watching the IIS Smooth Streaming page. I probably get the same in silver light in the Timeline, which comes with the near identical SU4100).

 

and do you have an extern LCD connected on your timeline?

 

I contacted the acer support who told me that probably the video refresh rate is too low. I checked that and they were right, it was 59Hz instead of 60Hz. A change didn't really bring a big difference in silverlight though :/

 

I'm sorry for the late reply.

I do when I am playing BluRay and Netflix. Sometimes Hulu and Youtube (I think those use flash, though), on a 1080p Mitsubichi DLP TV

I only go to the internal screen if I am playing youtube by myself. Though I gave that laptop to my mother, so I don't know what happens on that, anymore. I still will have my m11x (it also has a GMA 4500MHD), if you wish for me to test out more things
