Yes, I can. > > Why do you want to make a non standart SVCD (-f 5) ? Well, the previous answer was obviously a joke. I removed r,g,G from mpeg2enc and V from mplex. I got a slightly smaller mpg (4668916). Same result: out of sync. Now to this answer: I don't really remember, I think it was something about GOP between 6 and 18, I surely don't remember. > Does it work if you use -f 4 (Standard SVCD) ? No. One very strange thing I forgot to mention: The film starts black, fading in. Sound is also silent, fading in. As soon as I hear the sound it is somehow interrupted (come and go). When fading finishes, sound comes before the video. > > > Script used to generate t.mpg in mplex: > > mplex -f 5 -V -S 900 -o t.mpg t.mpv t.mp2 > > When you use a non standart maximal bitrate you should add the correct > bitrate when you multiplex the stream afterwards.

It's a long story. Turning it very short: I used to author using VCDEasy because I want chapters every 5 minutes. And a GUI. And SVCD. QDVDAuthor only makes DVDs. Tovid needs to encode video. So for the moment I stayed with VCDEasy. VCDEasy actually runs vcdimager under cygwin so the result is the same without the need to type xml by hand. I would be very glad to hear a suggestion. > > auf hoffentlich bald, > auf wiederlesen! <- if it exists > Berni the Chaos of Woodquarter > > Email: [EMAIL PROTECTED] > www: http://www.lysator.liu.se/~gz/bernhard Do you have an english version of your homepage?

HmmmI'm not sure what you mean by 'timecode' here. Is this something coming back from some player software? Also are the differing timecodes from *running* mplex under windows or playing the result. If you have a short sample (a few seconds of video and audio is ideal) that demonstrates the problem I can easily take a look to see what the differences are... cheers, Andrew --- This SF.net email is sponsored by: Splunk Inc.

[Mjpeg-users] mplex problem with hardware DVD player
I am having a problem with mplex for a certain hardware DVD Player (Philips DVD707): I put the SVCD in the player and it starts playing, but video and audio are out of sync. But if I fast forward or "rewind", the video gets instantly in sync! I have another hardware player (Philips DVD615) which always plays correctly. So I need to upgrade the firmware of the problematic player? Not quite. I installed wine and bbmpeg (v1.24 beta18). I multiplexed with bbmpeg under wine and I don't have this problem at all. I think it is something related to the beginning of the mplexed stream because if I jump to a chapter it also gets in sync. Script used to generate t.mpv: smil2yuv t.avi | yuvscaler -v 0 -n n -O SVCD -M BICUBIC | mpeg2enc -H -V 46 -v 0 -n n -I 1 -a 2 -b 1897 -f 5 -q 4 -4 1 -2 1 -r 32 -g 6 -G 18 -S 900 -B 260 -K tmpgenc -o t.mpv Script used to generate t.mp2: smil2wav t.avi | mp2enc -r 44100 -b 192 -e -o t.mp2 Script used to generate t.mpg in mplex: mplex -f 5 -V -S 900 -o t.mpg t.mpv t.mp2 Options used in bbmpeg under wine: Program Stream Settings: VBR: on Write program end code: off Add SVCD scan offsets: off Align sequence headers: on The video in question (only 20s to keep things short) can be found at: http://delio.homelinux.com/mplex/ t.mpv is mpeg2 video only (4M). t.mp2 is mp2 audio only (476K). t.mpg is multiplexed with mplex (4.5M). t_bbmpeg.mpg is multiplexed with bbmpeg under wine (4.5M). t.avi is the DV video (20s) (73M - not necessary to test). t.sh is the shell script l.txt is the output of the shell script Authoring was done with chapters in VCDEasy v.1.1.4 in Win98, SVCD format. Any ideas? Is there any parameter missing in mplex? Many thanks in advance! --- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!

[Mjpeg-users] mplex sync offset blank problem
Greetings, Thanks for all your hard work. Combined with DVDAuthor, this is an amazing tool. Recently, I found I needed to offset my ac3 7310ms (yes, I know, that's big) to sync with my video. Quite a few errors later, mplex finished; reporting buffer underruns. I tried authoring with the file, no luck at all. Later, I used a dvd authoring program (dvdlab) to adjust the ac3 stream sync (it adds blank time to the front of the stream), then using that new ac3 (with 0.7310s added) in Mplex and all worked great! Straight through authoring and playback. Thus, has anyone looked into the way the sync offset is done? Would it be possible to automatically insert the needed "blank" ac3 stream data instead of just delaying it? Seems like a bug. :) Thanks Rob ps. options were -f 8 -O 7310ms -V The file was completely playable in all media players, but would caused a non-working dvd when authored through with dvdauthor. --- This SF.net email is sponsored by: Splunk Inc.

[Mjpeg-users] mplex timecode problem
Hi! i have a problem with mplex and timecode. if i use mplex (2.2.1 from mjpegtools.1.6) under windows (xp sp2), everything worsk correct. if i use mplex (2.2.4 from mjpegtools 1.8) under linux (debian sarge), the timecode of the file is wrong. i have a m2v and a mp2 file, the mp2 file has a timecode of 9:47 minutes, and thats right. with windows, the timecode of the mpg file is 9:47, with linux the timecode is 5:23, why that?? regards, dunsti

But as I encountered something simmilar (but in my case the blocks beeing green :) ), I would like you to: a) verify that these blocks are not introduced by mpeg2enc (which was it in my case) and b) if they are really introduced by the denoiser send me a ca. 50 frames y4mstream (please use bzip2...), as well as the used thresholds, so I can investigate (and possibly remove) that behavior of the denoiser, as it clearly should not add unwanted blocks... cu Stefan -- Gnomemeeting/Netmeeting: callto:ils.seconix.com/[EMAIL PROTECTED] ICQ: 131490319 --- This SF.net email is sponsored by: Splunk Inc.
