VOB files stuttering

[bryantjopplin]

I have tons of dvd vob files that play just fine when they aren't being transcoded but when they are even on a 866mps wireless ac connection and wired connection they are stuttering. Every other file I have plays fine, it just seems the transcoding for the vob files aren't up to par. Thanks.

Edit: I guess I should have said I have noticed this in like all of 4.0 and 5.0 with 6.0 alpha. I have a i7-4770 and 16gb of ram. Read that it could be the encoder introduced in that updated sb42 or 43 cant remember.

Blind guessing if you don't provide more info, as stated in red above viewtopic.php?f=9&t=556

I don't think it's a bug is why I was asking. Just wondering if I missed a step.

I don't know if this has anything to do with stuttering, but we've gotten a tip that

Code: Select all

container == iso :: -nosync

causes synchronization issues for DVD ISO's.

You could try to change it, or tinker with the transcoder settings by going to "Transcoder Settings" -> MEncoder -> Codec-specific settings. Since you can't "remove" a setting from the default, you have to disable "Use application defaults" and then paste the other lines under "Custom parameters":

Code: Select all

(container == avi || container == matroska) && vcodec == mpeg4 && acodec == mp3 :: -mc 0.1
container == flv :: -mc 0.1
container == mov :: -mc 0.1
container == rm  :: -mc 0.1
container == mp4 && vcodec == h264 :: -mc 0.1

This is a shot in the dark, but it could be worth trying.

Looking at your configuration, I see

Code: Select all

maximum_bitrate =15

Try setting this to zero.

I had it at zero. Just was trying different strings to troubleshoot. I will try the other when I get home.
Thanks

Ok the stuttering isnt as bad but about 5 minutes in it stops playing. here is the log

I'm simply in over my head here, I know very little about this and just remembered someone else saying that this parameter broke DVD ISO playback. The only thing I know is that these lines is thrown constantly during playback:

Code: Select all

DEBUG 2016-01-10 15:22:42.037 [mencoder.exe-14-2] net.pms.io.OutputTextLogger [mpeg2video @ 00ea8940]rc buffer underflow
DEBUG 2016-01-10 15:22:42.037 [mencoder.exe-14-2] net.pms.io.OutputTextLogger [mpeg2video @ 00ea8940]max bitrate possibly too small or try trellis with large lmax or increase qmax

Whatever buffer "rc" is, I'm pretty sure that's the reason it stutters. You'll just have to wait until someone that knows more about this than me comes along.
