new doom9 codec comparission
by Michael Niedermayer 09 Dec '05

09 Dec '05

Hi doom9 is planning to do a new codec comparission, and they are asking me to provide them with 2pass settings (lavc mpeg4 & lavc snow) for the "qualification round" against xvid 1.03 with the matrix as movie they need a single set of options not a mix of possible good ones from which they would have to select, thats also why they refuse to ask here, they are also askng which binary of mencoder they should use iam not forwarding their mail as it was in german ... so we need a volunteer who has some experience with encoding, can provide them with all that and furthermore could double check that nothing silly goes wrong like using a player with postprocessing disabled for viewing the mencoder encoded video while one with pp enabled is used in the other cases if you want to volunteer just reply to the list ... if you dont do that, then shut up and dont complain about what doom9 will say about libav*/mencoder in the unlikely case that we end up with multiple volunteers who cant agree then ill decide who is the official one they should listen to i belive this should solve the issue doom9 had with asking here PS: also dont forget to ask if the test is just quality wise or speed wise too -- Michael

Audio sync problems
by Karl Mitchell 02 Dec '05

02 Dec '05

I'm a returning user to mencoder (last used in 2003 under Linux), so my apologies if the answer to my question seems obvious. I've been trying to backup a DVD to H.264/AAC on MacOS X 10.4 (Tiger). I managed to compile mplayer/mencoder from CVS last night (2006/11/25) with x264 and faac support, so no problems there. However, I've been having major problems with lip sync, with audio being a significant fraction of a second ahead of video. I suspect that the problem I'm having is due to the input being mixed progressive and telecine NTSC, a format I've never used before, as I used to live in a PAL country. The following is my attempt at a first pass: mencoder dvd://1 -dvd-device /Volumes/Neptune/Movies/DVD/VIDEO_TS \ -alang eng -oac faac -faacopts br=128 \ -vf pullup,softskip -ovc x264 -x264encopts bitrate=1200:turbo=1:pass=1 \ -ofps 24000/1001 -o title1.mp4 I have also tried using -mc (values of 0, 0.1 and 1), with no success. -oac copy seems to produce similarly out of sync results. mplayer dvd://1 -dvd-device /Volumes/Neptune/Movies/DVD/VIDEO_TS works fine. I can't find any clues to solve this in the documentation (which only has -nosound examples for mixed progressive and telecine) or man page, and would greatly appreciate any help. On the plus side, this basic first-pass H.264 encode seems to already be producing extremely good video results at only 1200 kbps. I look forward to seeing the second-pass results. Regards, -Karl P.S. mplayer.hu (as opposed to www.mplayer.hu) appears to be down, and so I had to subscribe to this list in the old-fashioned (unadvertised) way, i.e. by sending a blank e-mail to mencoder-users-join(a)mplayerhq.hu.

anime,pullup,skipped/duplicated frames
by Gábor Farkas 01 Dec '05

01 Dec '05

hi, i am trying to encode something from an anime dvd. first i am trying to find a way to get rid of the telecine, -vf pullup works fine, when i play the video with "mplayer -vf pullup", i can see that every fourth frame is duplicated (so it was like ABCDD ABCDD ABCDD ). i tried something like this: mencoder -oac copy -ovc lavc -lavcopts turbo arusu-intro.vob -ofps 24000/1001 -vf pullup,softskip -o arusu.avi what i get at the end looks ok, but while encoding i'm getting frame_skipped and frame_duplicated messages. for 90seconds of anime, i got 75skips and 22 duplicated frames (full gzipped mencoder log attached). isn't that too much? or is that number ok? why? should i maybe try a different -ofps? thanks, gabor

wmv encoder audio problem again - urgent
by ARTUR SZYMIEC 30 Nov '05

30 Nov '05

When deocding wmv audio 5.1 video to ac3 channels order is not correct. Why the output channels order (L,R,LF,RF,C,LF) is not correct ? Is there any stadart layout for -af channels to correct it ? (I mean both for dvd with ac3 audio and wmv). And the last one - is this a bug that will be corrected in future versions ? Best regards A.

-ffourcc avc1 -of lavf = floating point exception
by Fredrik Eriksson 30 Nov '05

30 Nov '05

mkvmerge wouldn't accept h264 as fourcc in the mp4 file I created with mencoder, so I tried to remux it: mencoder-cvs -ovc copy -nosound -ffourcc avc1 -of lavf -lavfopts format=mp4 CCS.try1.mp4 -o CCS.try2.mp4 This results in a floating point exception directly after WRITTEN HEADER (no matter how many -v I add to the command line) remove -ffourcc avc1 and it works just fine. this is with the latest cvs (updated just a few minutes ago). Known issue? Fredrik

is there a way to join 2 AVIs with mencoder so that the resulting AVI is correctly indexed? suppose both parts have the same parameters (video bitrate, audio type and bitrate). toba

Re: [MEncoder-users] subtitles disappear with mencoder

> It was suggested some time ago that you try -vobsubid, and I don't recal > any messages from you stating that you've tried it. > yes, i tried that right away and wrote about it immediately afterwards. as i said, -vobsubid isn't an option for mencoder. there was another comment that a patch for mencoder could add the -vobsubid option, but it's on an old codebase and might not work with the current cvs, and it's now been said that this isn't an appropriate use of the -vobsubid option anyway. also, -sid has never not worked for me with mencoder before, so i'm not really clear why it would require a different option in this case. thanks, -steve diverdi -sdiverdi(a)cs.ucsb.edu
