MKV playback with LAV in fullscreen (minimized it's ok)?

[ionutm80]

I left your default settings unchanged - meaning using LAV decoder, and I've only selected Intel QuickSync as hardware decoder. Everything shows fine ...BUT only when the window of mce is not in full screen. If I go in full screen there is no image or sound. If I'm exiting full screen and go to a smaller window of mce I get video and audio perfectly syncronized, with subtitles and I can see that dxva is working (CPU load 7-10%). This is only happening with mkv 1080p, my TV only has max resolution 1366x768. Do you have any idea here?

THIS SOFTWARE (Maxifier) will most likely solve your issue.

1366x768 is a PC resolution, if that becomes active while MC7 is in full screen, then the TV may no longer be recognized as HDMI/HTPC device and HDMI audio/video device shut down. Only with a TV resolutions (eg 576i, 720p, 1080i, 1080p ...) that is guaranteed. Accordingly, they should MC7 TV-Device-Setup set to 16:9 flat panel with HDMI and 720p/60 Hz (1280x720/60 Hz) for NTSC or 50 Hz for PAL!

Hello Shark and thanks for your quick feedback, but on the linked site it says "The Maxifier is a application that assists in running Vista Media Center on two screens." and I want to have mce in fullscreen only on the TV (I don't have another monitor connected). The issue is that with ffdshow I don't have this problem but I do have a/v out of sync. With LAV everything has been solved but something is blocking when I go in full screen (if I reduce the screen I have a/v again, I can even drag the corners of the MCE to fit the entire screen but it's iritating, I wish I have video and audio directly in MCE fullscreen). Is there a setting in LAV that I need to work to?

Hello HD-False,

You've lost me already...if it's working when ffdshow is enabled why not with LAV? I have no problem also in other mediaplayers and yes my MCE setup is with connection to flatpannel/lcd.

it also states,
"A beta version of 1.5 for use with Windows 7 is available here. Please let me know if it works or not for you."
I have read elsewhere that this software solves the exact issue you are dealing with. Wouldnt hurt to try . . .

If you set 1280x720 and this happens only with the LAV decoder and Intel QuickSync, then it's the "buggy" Intel driver.
Do you have the problem even without QuickSync?

Hello hd-false and thanks for your help,
I only have this problem with lav, with ffdshow and intel quicksync for hw acc I have no problem with full screen mce but other problems: if I pause and resume a/v goes out of sync. During wk i have tried all shark versions from 3.3.1 to 3.6.2 and up to 3.4.7 a/v is perfectly syncronized but embedded subtitles in mkvs are not loaded only external ones. Above 3.4.7 embeded subtitles are loaded but av goes out of sync with pause /resume. If i play continuously the whole movie than it stay syncronized.

I have "only" ATI graphics cards and use FFDshow-DXVA decoder under "H264" Tab (MKV with H.264/AVC or VC1) or the FFDshow Video Decoder (AVI, MPEG, Xvid..) for the subtitle display (see for example here). I have no problems with MKVs in HD and SD.
But I do not know if FFDshow DXVA with Intel HD graphics has problems.

You can please upload a 40 MB sample of your problem-mkv with "Settings -> Misc -> DragNdrop", so I can try this with my Shark007 settings?

Hello hd-false,

Pure dxva does not work well with intel sandy bridge gpu indeed. I have several files that have artefacts. Intel quicksync implementation in ffdshow / lav is a sort of a dxva workaround made unofficialy by intel engineer called Egur and is a hw acceleration method specialy tailored to intel sandy bridge gpu. I think the problem lays in fact in the integration of this in ffdshow / lav. Anyway I will try to update a sample but I can bet that on your amd system there won't be any problem.

I recommend an ATI graphics card HD6570 or better, brings a measurably better video picture and has no problems with BD 23.976 Hz!
