DVBViewer on GMA500 Platform

[Kelvin Left]

Hi, I am using DVBViewer Viliv S5. The display chipset is Intel GMA500, which is common in Netbook. I found the DVBViewer failed to work using Overlay mixer. No matter which decoder I used (DXVA or soft decode) the output window is only black screen but I can hear the sound of the TV program. When I switch to use VMR9, the TV program can be decoded to the output window but it can be seriously lag. When the program is in standard resolution, the video is fine when I used software decode (FFDSHOW), but it lag seriously when I use PowerDVD H.264 decoder (DXVA enabled. I am sure about this since the CPU usage is almost zero, compare to over 50% CPU usage using FFDSHOW). When the program is HD (1080i), the video lags with all decoders.

 

I am pretty sure the GMA500 can handle the HD stream since the recorded ts can be played using Media player classic - Homecinema flawlessly.

 

Any comment? Thank a lot!!

Install windows 7 and use EVR mode and everything should work.

Do you mean DVBViewer cannot support GMA500 in WinXP but only Vista and Win7? If so I can only give up the DVBVierwer since I have too many apps cannot run smoothly in Vista and Win7. Also, Win7 need too much disk space. My S5's SSD is a tiny 32GB one...

 

Thanks a lot.

I did the test with windows 7 the result is not beautiful. I hope that render of DVBViewer will provider total support for intel GMA500 . We have this chip in a lot of notebook. I did the test with MPC-hc with hd .ts recorded by DVBViewer and the result is very fine, a real fluent video without any lag.

The processor has only one core ok supports hyperthreading.

But the intel graphics are known for their louzy performance.

Zotac for instance combined the Intel ION 330 with the Nvidia Ion to remove the Intel graphics bottleneck.

the ion performs better.

 

 

No no, playing a recording is not the same as receiving the signal to show the video.

Quality of the DVB device, it's firmware and tuner specifications, how good is the dvb card driver, these are extra thing that can tear down reception.

 

I'm testing the zotac ION but not yet what I want, SD works fine, HD not yet.
