Glad to hear it - just test each in isolation of the other and see if one or the other is causing your issues. That way you'll have a better idea of the root cause.

Just a update i asked some pages ago in this thread


Had great success with the mac mini (base 2011 model with intel 3000 hd to bitstream to my pio vsx921)

Now if the stupid ir reciever in the mac mini worked in windows so i could use my haromy all would be great. However that doesnt work, so i have to wait 30 days for my ir reciever to arrive. Oh well. Great work. Switching to windows soon enough.

Btw i tried both enabling and disabling dxva, but i couldnt see any lag/stutter or weird artifacts anywhere. Just remembering someone told me i had to disable dxva to get it work properly

That all depends on what format the video is in that you are watching with a Sandy Bridge GPU. The problem is with H.264 video decoding. You get some serious blocking on the screen during playback with DXVA2 enabled. You can get around this with FFDShow because they added support for Intel QuickSync, but I am not sure if ffmpeg ever did or not. I confirmed that this issue still exists in DDDamian's 4/25 build, testing with Iron Man 2 that was just remuxed into a single M2TS file; it has H.264 video and DTS-HD audio. I get no audio with DTS-HD in that build, but I am sure that will be fixed as it is the first post-Eden build.

@OtisPresley - two devs are working with Intel on that right now Smile

That is great news! It currently works fine with software decoding, but it taxes the CPU way more.

Try the video sample posted by Tman12, you'll see what we meant......brief green pixelation during resume

Hmmm...

Ok, im having issues on one of my htpcs.
I'm using Daniela's build on the front page.
Windows 7
Hdmi (ion)

When I pause movies, on resume they are either out of sync, stuttery or have no audio. I have to rew/ff a few seconds to get it o "jolt" it's self back into joint.

Multi chnl PCM centre Chanel dialog comes through my rear chnl, when my audio config is set to 7.1 in xbmc settings. Changing this to 5.1 in xbmc resolves this, Even though I dont have. 5.1 setup (8.2).

PCM audio (when change resolution and sync to audio clock are enabled) drop out and disconnect after 2 or 3 seconds? This problem cn be resolved by disabling sync to audio clock and the movie plays fine?

Just posting this to get eyes on it, no log as of yet, no sample cut from the movie yet to post for you guys to test.

Anyone experincing similar?

That said,
It's still incredible and other than the odd hiccup I can't really fault this awesome work don't in here Smile

Yes, after pause audio stutters. I just toggle language and then it is ok again...

A quick test on my rig didn't exhibit any audio stutter after long or short duration pauses (tested with DD, DD+, DTHD, DTS-MA). I will try to run more tests when time allows.

Hi,

Same issue here on the audio after a pause. I get bad pops coming through the speakers. If I navigate a few seconds back on the scroll bar it's all fine again.

As a second point...

Is there anyway I can confirm that my amp (Denon AVR 1911) is passing the switching signal to the TV to change it's refresh rate to match the video output i.e 24hz for 23.976 playback?

Bluray rips at 1080 are looking particularly jittery in panning scenes. They are perfect when played via MPC-HC. I could just set up the advanced setting XML again to use the external player when 23.976 content is played but I have got quite used to the internal player controls and the wife thinks they are user friendly as well in comparison to MPC-HC.

Regards,

Simpic
