Xvid decoder problem?

[LilY0da]

That is one scary command line!!! I'll try it soon.

EDIT: sorry for being an idiot, posted in here a post for another thread

Anyway, I tried it Humperdinck, and it works fine. It creates good quality files, and keep the filesize low. And the FourCC is set correctly!!

Massive kudos on the work done!

I used the command line and library given by Humperdinck, and the quality was great! .. except, only 43 minutes of the original 2-hr long recording was in the converted xVid file.. any idea why this would happen?

[LilY0da]

out of disk space while it was encoding?
Did you keep the .mpg file?

BTW, if you use XviD, remember to remove the -deinterlace flag, or comskip files won't work

[sgilani]

Yeah, I kept the .mpg .. certainly didn't run out of space (180gb free )
I give GBPVR 4 hours overnight to do transcoding, it's not a time issue is it? (i highly doubt it, but i dont know)

And thanks for the deinterlace tip! a bit off-topic, but when i'm in timeshifting mode, and i pause for a bit and then resume playback from the buffer, is the video still being fed through the same mpeg decoder and renderer; does anything change?

I'm asking because I get a weird judder when watching live tv in preview or timeshift, and using DScaler with 3:2 pulldown smoothing fixes it for me.. except when i rewind or pause/resume while timeshifting, then the horrible judder comes back.

Hi sgilani, dunno what could be causing the timouts for you. I've been encoding left and right here and so far all is fine.

I enabled comskip after reading the other threads in the forum and I must say I'm impressed. I save using the guide and comskip+cuttermaran+my slightly modified comclean2 churns out xvids of movies and tv series.

My guess is that 4 hours wasn't enough to encode your recording.

How big is the encoded file? Why not you try playing the video in VideoLan? There's a size limit for AVI files and not all programs can play the complete video above a certain file size (i can't remember the size already). I have a few videos that appeared cut off when played with GBPVR or Windows MediaPlayer but plays full length with VideoLan.

I think the problem was just time; it seems to work fine now.

But, using that long commandline posted by Humperdinck, I'm getting very large files.. a short 15-min clip was right around 1 GB, and a half-hour show came in right around 2 GB... ? I guess I can just go back to a simple bitrate setting.

but still comskip files dont work.. (i'm not using the -deinterlace option). Anyone else have this problem?

That's strange, my recordings of for instance a Seinfeld episode is around 1.5Gb as mpg and my encoded result is around 500 megs. How big is your recorded original?

Cheers, keep us up to date. I'm absorbing all this info for incorporation into the next release of GB-PVR.

Unfortunately I find it difficult to find time to tinker to this low level myself.

Sub, any chance that a future version could allow us to choose our own encoder? Either specify it in the config or alternatively in the config.xml or even just prompt for a command line in the gui?

I have tried Mencoder and find it much faster than ffmpeg.

Cheers
