Audio/Video Sync

[mvallevand]

Ok, that helps. It looks like a pretty basic svcd file which really shouldn't lose sync. 0xCO for audio will be MP2 Audio. At this bit rate the mux should be full too. So I have a couple of questions

Are you running wired or wireless?

Do you use the mvpmc share to load a command line?

Wired and wireless... They both behave identically.

No I do not have a share for the dongle. I choose emulation mode from the menu manually... I rather like that It keeps the mvp from having an active session on the pvr computer.

Thanks,

Matt

I figured, this doesn't look like it is bandwidth related. Could you telnet to you mvp, log on as root and issue this command after the #

ifconfig

I am interested in seeing if you are getting high number of errors or collisions.

I am assuming you are running full duplex and not 1/2 which the Hauppauge dongle prefers.

So do I, I am actually surprised at the number of people who like to keep the connection open, taking resources on the server since the connection time is so short.

The switch to which it is plugged says fdx

That sample set is probably a little too small... Let me repost after I try playing a movie.

That's a reasonable sample and the six errors wouldn't cause the problem you talk about. Collisions affect performance the most and you don't have any.

Sub, (if you are reading this thread) in the gbpvr dongle, do you remember if you ever issued an av_sync() commands while the video was playing or did you let the demux handle everything like I do?

Martin

[mvallevand]

Matt, the sync that I asked sub about is issued on a pause. Does hitting pause/play resync this file?

My guess would be that the problemis in the transcoding, I've seen a lot of sync problems with dvd>mpg. You might try videoredo, you can use it as a trial, It has a very nice timestamp fixing routine. Then you would know if it's in the transcoding.

[matthrolf]

I am not transcoding. They are MPG2 files.
