lav can't work.

Works just fine here.
Did you enable the "msrle" codec in LAVs format options?

Its disable by default, but i don't remember anymore why. :P

Yes i did.

lav s + lav v, ok (no audio decoder exists)
lav s + lav v + one audio decoder, stops at the beginning

[nevcairiel]

The file has a broken audio stream. However, still plays fine for me, simply doesn't output any audio.

[wanezhiling]

Oh i knew why, lav just need a long playback's preparation time, about 11 seconds.

subtype: MEDIASUBTYPE_PCM is incorrect for Video stream.

[nevcairiel]

Thats the same mediatype that the MS AVI Splitter or the MPC-HC AVI Splitter output, as well as the FourCC thats actually contained in the AVI file, so yes, it is correct.
Nothing wrong with {00000001-0000-0010-8000-00AA00389B71} being both MEDIASUBTYPE_PCM and MEDIASUBTYPE_RLE. The majortype gives it a clear distinction.

I have recently bought an Intel nuc (DC3217IYE).
Intel Core i3-3217U, 2x 1.80GHz, 3MB Cache, Intel HD Graphics 4000 (IGP)

Using Win7 64bit and MediaPortal 1.3.0. Playing h.264 HDTV recordings, BR-Rips, etc.7as it is on my other Systems also using lav.


The Problem I have with the LAV videocodec on that box is that the vidoquality is not as good as it could be.

There are strange artefacts sometimes (Decoding glitches?) as well as the videoplayback looking "not smooth" (no dropped Frames though and CPU load is always below 20%).

I tried using Intel quicksync and dxva. Same issue with both.

On my other HTPC's using nvidia and AMD gfx Cards and the same lav filters, the issue does not exist. Everything Plays just perfectly!

Are there known Problems with lav and the Intel nuc/4000HD ?

I'm running a "normal" i5 3570K with Intel HD4000 and didn't encounter any problems.

Install Intel drivers from their website, not Windows Update. Disable all (except perhaps detect film mode) "image enhancements" in the driver's settings.
Perhaps try a different player? MPC-HC is a free, commonly used one.
Also what comes to mind after reading a few reviews of NUC, maybe your CPU/GPU is overheating? Check the temps with GPU-Z or HWiNFO, best during longer playback (full movie or similar) with the app monitoring temps in background, check max and average temps afterwards. Running OCCT in GPU mode might also be a good idea, remember to enable the "error check" option.

That's it for general ideas, maybe someone has more experience with NUCs.

Ok - i see. But - inernal MPC Avi splitter & system AVI Splitter can connect to the "AVI Decompressor" to playback this file. LAV Splitter/Source - can't.

Another bug or issue - on this avi http://aleksoid.voserver.net/Sample/...TV_split_0.avi
LAV detect/calculate incorrect duration - 00:03:38 instead 00:03:50. This file just a split by dgsplit.

I have set them all to "let the application decide". Will try to disable them.

Yes but MPC-HC does also have (some) codecs inbuilt if I remember correctly. Or can I tell MPC-HC to only use directshow/lav ?

Temps are fine. The Fans slow down a lot when starting the playback.

That's what I should have written - disable the ones that have enable/disable, set others to application, and you're done.

With this settings, I have no problems on my "normal desktop" Intel HD4000, using MPC-HC + madVR + LAVFilters with either software, QuickSync, DXVA-native or DXVA-copyback decoding. Hope this helps.

LAV has no support for Media Foundation, and it will not any time soon.

If yes: how?

Sure, rewrite the decoding path it uses. Have fun with that.

No.

Edit: btw what's wrong with default windows decoder? Sure LAV is much superior, but for watching crappy youtube videos decoder from MS will do just fine.

[nevcairiel]

Its not possible unless you rewrite firefox, so you should get on that instead!

Its simply not possible, you can stop arguing now.
