Hi guys (and gals),

I'm hoping someone can help - everso often when watching live TV (single seat) the audio is out of sync with the video. It doesn't happen all the time though

I haven't fully tested/check all channels, but I know it happens on SD channels.

I am running SAF, but with Microsoft Codecs for TV (as PDVD ones had micro stutters for me).

I am running SPDIF passthru, with FFDAudio selected, with a 200ms delay (defined under the delay option) . I am upscaling to surround sound from stereo - Like I said previous everything worked ok (prior to RC2).

When the audio gets out of sync, if I change channel and back again it resyncs again - So I'm not sure if its a codex/ffdshow issue or more a Mepo issue?

Pausing live TV and resuming does not solve the issue.

I have checked in graphstudio when the audio is out, and it states its still using FFDaudio (so I am assuming the delay is still being applied)

I am having to rebuilt the HTPC this weekend (due to another issue), but I want to ensure (well at least have confidence) that this issue wont come back with RC2??

The attached logs have the audio out of sync (audio is ahead), they have the pause and resume, and also the channel change where it fixed the issue.

Thanks,

J.

I have this issue as well, will post my stuff once I figure out how to do it. I use the FFDSHOW codec for video and audio - how do I recorrect it so that audio is not out of sync?

Hi there,

I have switched back to SAF4 - this seems to have fixed it (looks like it was an issue with the ffdshow audio version in SAF5).

I'll test somemore and keep an eye on things.

i have had the same issue since installing SAF 4 and using ffdshow for both audio and video

Hi there,

I can unfortunately confirm that the issue remains with SAF4.

As soon as I change channel, the audio is back in sync.

I will try and capture some logs at the time it happens (difficult when I might not be abaout and the other half is using the TV and she simply changes the channel up and back again)

Time to do more searching - see if anyone else has the problem - need to find out if its a ffdshow issue or a MP issue (my hunch is MP at the mo).

thanks,

J.

Yeah there's an issue with ffdhshow audio. After a few minutes it goes out of sync when using passtthrough

I have the same issue. Fast forwarding or rewinding resync the audio.
Very annoying.

Same behaviour here.
Using metiaportal 1.1 Final Release and SAF 5 (Win 7 x64).

Any workaround?

how long does it take before the out of sync is noticeable? 5 mins? 1 hour ?

Does the de-sync happend if you recor something and play your recording or only on LiveTV?

Just for test, can Win7 users set VMR9 renderer insted of EVR in MePo codec setup and try again?

Acording EVR.LOG there is lot of droped frames - maybe that causing desync?
