It > makes no reall sense to me. Berni, it is very easy to understand. I don't copy DVDs, but make own films from my dv-camera. There are two things, which are very important to me: high quality and the possibility to create DVDs from my XSVCDs later *without* reencoding and having other unexpected problems. As long as my standalone-DVD-players accept the XSVCD with DVD parameters I think -f 8 is the securest way to get no problems later, when I make a DVD from the mpg-file of the XSVCD. With a videobitrate of 5000kbps I can make a film with about 23min. That's enough for me. Most of my clips are about 10min. and then I use 6000kbps VBR. A simple command: transcode -i /multimedia_out_nfs/encodesource3/ -V -y mpeg2enc,toolame -F 8 -o test used the following default values: [export_mpeg2enc.so] cmd=mpeg2enc -v 0 -f 8 -b 1800 -F 3 -n p -o "test".m2v and transcode -i /multimedia_out_nfs/encodesource3/ -V -y mpeg2enc,toolame -F 5 -o test created: [export_mpeg2enc.so] cmd=mpeg2enc -v 0 -q 3 -f 5 -4 2 -2 3 -b 1800 -F 3 -n p -V 230 -o "test".m2v So the difference you see, is: -q -4 2 -2 3 I use different -q values with different sources. But does it make sense to use -4 2 -2 3 for encoding DVDs from dv-camera-sources? Al --- This SF.net email is sponsored by:Crypto Challenge is now open!

Not the friendliest interface in the world, but perhaps better than iterative tweaking. Still, I'm not that good at eyeballing color balance.

Since the first patch really only changes the sequence header prog_seq bit the desync bug will probably only show on some decoders.

Re: [Mjpeg-users] changing the hue prior to encoding
Does anyone on this list know how I can change the hue of a video inside of the encoding pipeline? I made a recording with my camcorder and I forgot to do the proper white-balancing prior to the recording. As a consequence, I now have a DV file on my computer that has incorrectly calibrated colors, and I want to correct those colors before I encode the file to mpeg1/mpeg2. I've done that a few times. What you want is yuvcorrect. Here's some examples I've used to correct white balance: # approximate white balance correction for indoor (incandescent light) shot # using outdoor white-balance setting. yuvcorrect -M RGBFIRST \ -R R_1_0_255_0_180 \ -R G_1_0_255_0_215 \ -R B_1_0_215_0_255 \ -Y Y_1_0_190_0_255 # a milder version yuvcorrect -M RGBFIRST \ -R R_1_13_224_0_255 \ -R G_1_12_204_0_255 \ -R B_1_0_176_0_255 # outdoor natural light shot with indoor white-balance yuvcorrect -M RGBFIRST \ -R G_1_0_255_0_185 \ -R B_1_0_255_0_180 \ -R R_1_0_180_0_180 \ -Y Y_1_0_220_0_255 Note that in each case I'm not just adjusting white balance (which would just involve shifting), but also scaling to maximize contrast. These were in some cases ad-hoc tweaked until I liked how it looked, or in some cases I pulled a screenshot into the Gimp and checked out the histogram, etc. You can do some of the same stuff in YCbCr directly, but RGB is just easier to think in. What I'd really like is a tool that will scan the clip (or part of it) and automatically correct white balance and/or maximize contrast. Hand tweaking of yuvcorrect parameters is tedious.

If you look for the string SVCD and DVD in the source code you'll see the exact differences that are set! Basically, SVCD inserts stuff needed for SVCD DVD for DVD and there are some differences in the way system headers are constructed. However, since its all MPEG-2 a *well-written* MPEG-2 decoder should be able to handle both. Software decoders can usually handle almost anything (they mostly ignore the more-or-less redundant header infos anyway). Alas, you typical set-top DVD/SVCD player is rarely a well-written MPEG-2 decoder. Usually slightly flaky and only tested on a limited range of streams and go nuts if they hit optional headers they don't expect or similar.

A hypothetical "yuvcoloradjust --hue -20" or something like that. Of course, I can extract all the frames to separate images and use ImageMagick to do the job, but if there is a simpler way, I'd appreciate to hear about it.

Is anyone successfully using the CVS version of mpeg2enc to encode 23.976 fps progressive material with the 3:2 pulldown flag for playback on a 29.97 fps NTSC tv? If so, can you post your mpeg2enc flags? I'm having fits getting this to work post-1.6.1. I've tried both "mpeg2enc -I 0 -p -F 4" and "mpeg2enc -I 0 -p -F 1", in the latter case mpeg2enc seems to just force -F 4 anyway. I've done this for both "yuvkineco -F 1" video (animation) and a commercial DVD, with the following results: 1.6.1 and before: Works great CVS: Linear increase in loss of sync. Video plays too slow, on mplayer at least. Forcing -fps 40 fixes it, not sure why. Same deal if I multiplex with tcmplex instead. The actual pulldown code is just a few lines, and is identical between the versions. I've tried using bbinfo and bbvinfo to compare the two (not that I lnow what most of the output means). One difference is that 1.6.1 sets progressive_sequence=0, while CVS sets it to 1. Another is that top_field_first is inverted between the two.

Yes, I think a number of folks have mentioned that the yuvmedianfilter tends to over-soften the picture if the luma component is processed. Most of the filters I'm aware of are from the NetPBM suite and really want to work with RGB data instead of YUV. A long time ago I did some experimentation with converting the data to PPM, processing the data and then converting back to YUV. Looked nice but it was quite slow. mpeg2enc does emit information that perhaps could be used in a 2 pass method. One could take the lines of the form: INFO: [mpeg2enc] Frame end 40348 19.19 1487017.09 6.0 243910.37 and construct a processing list for the second pass. On the second encoding run a filter could read the list and only soften/blur the frames that exceed whatever threshold is specified. Perhaps someone could write a blur (Gaussian comes to mind) routines that works on the 4:2:0 data so that conversions to/from PPM/RGB aren't needed. > I really just wanted to make it an optional argument to --reduce-hf, > but I'll be damned if I could get getopt to see the optional argument.

Just encode them one at a time, then burn them all to the DVD together. dvdauthor will just make a single DVD "title", with each MPEG file being a "chapter". Not only will that solve your file appending issues, it also makes it much easier to fast-forward through your DVD when you're done. This is exactly how I do it for my VHS to DVD conversions -- splitting it into several smaller jobs (about 10 minutes each) and burning them all as chapters. Works like a charm, and I never have any file size issues anywhere along the way. -- Robert Kesterson [EMAIL PROTECTED] --- This SF.net email is sponsored by:Crypto Challenge is now open!

[Mjpeg-users] difficulty appending, encoding
Hi. I've been spending some time getting to know mjpegtools and other video resources better so I can create a process for myself to import VHS tapes and encode them to mpeg2 and write them to DVD. As such, I've been pouring over the readme's and howto's and whatnot but I have an issue I can't seem to get past. Here's what I'm doing: I'm using lavrec to import 2 hours of video at a time from my vcr with my G400-TV. This gives me about 15 avi files ranging from 1.5-1.8 gigs each. I open the first with avidemux, append the next fourteen, and run three filters to crop, resize, and detinterlace (this is all NTSC). This gives me one big avi. When I play the avi in either MPlayer or Xine, it runs fine. But since I need to encode this to mpeg2 (going by the mjpeg dvd how-to and other resources) I rip the audio either by using lav2wav or lavtrans, and then I rip encode the video using lav2yuv: lav2wav hercules.avi | mp2enc -o hercules.mp2 lav2yuv hercules.avi | mpeg2enc -n n -M 2 -f 8 -s -r 16 -o hercules.m1v And then for multiplexing them to mpeg2: mplex -f 8 hercules.mp2 video.m1v -o hercules.mpg When I go to play the mpg file it looks great for about 8-10 minutes, and then the video freezes and the sound becomes a screeching blast white noise. I checked the mp2 file, and that seemed to be the problem as screeched also when I played it alone. I then took a different approach of going back to my 15 original avi captures and ripping the audio from the directly, and then appending them together in a wav editor. After re-encoding this gives me a perfect sounding mp2. Using this new mp2 file I re-encode the whole thing to mpeg2 again with lav2yuv. This time when I play the file the video simply freezes at the exact same spot as last time but this time without the white noise screech. At this point I think there must be something wrong with the way avidemux appends or saves the avi file. So I come back to the shell to try without visual aids. Since then I've been trying to use every tool I can find that I think I can substitute for avidemux including using lavtans as described in the mjpeg-howto under the "Unify videos" section. This starts to work until it hits 2-gig file size and then craps out. The how-to warns of this IF "there is the 2GB file-size-limit on 32Bit systems with an older glibc." I'm using RedHat 8.1 beta (phoebe) with glibc-2.3.1-46, so I'm not convinced that is my problem. Mencoder also hits this 2-gig file barrier, but then creates additional 2-gig files until its finished encoding. So as it stands now I'm just trying to get single giant m1v file that doesn't freeze, or identify what's happening to make it freeze. The only way I can seem to get a single avi file is with avidemux, which could be causing my problem, and I can't get a single avi file with lavtrans without encurring the 2-gig file limit. Also, it might be worthy of noting that the freeze point always happens at the exact same frame, and this is not a transitional point between two appended files. I'm also concerned that even I do get past the file size limit that any new mpeg2 encodings will produce the same freezing problem. I'm starting to think that I'm going about this all wrong by appending it all together into huge audio and video files before splitting and encoding. I'm confused to the point that I now seek the wisdom of my betters. *grog* I need to sleep. __ Do you Yahoo!? Yahoo!

Re: [Mjpeg-users] adjustable --reduce-hf mod
Based on the past couple days of encoding the one knob I really really want to tweak is the selecting blurring one - high motion scenes could do with a bit of selective blurring but only the encoder knows when that's needed... Is that something any of the current tools does in any sense (selective or not)? > mpeg2enc.cc to allow the amount by which the quantization for > high-frequency components is increased to be specified on the command > line. I couldn't seem to get optional arguments to work with getopt, > so I resorted to adding --hf-boost|-k, which takes integers from > 0-512, with 384 the default (as in the current code). 0 is the same Hmmm, the option name is confusing - it sounds as if the HF content is being boosted (which would increase the bitrate rather quickly I'd think) rather than the quantization of the HF. I told you it was a quick hack. Yes, it does imply just the opposite of what I meant. (You should see some of the code I've been paid to write!) Might I suggest "--increase-hf-q" instead? Or something that has "q" in it at least? If it makes it into the CVS, then you/Andrew/whoever have my permission to give it any name you want. :) I really just wanted to make it an optional argument to --reduce-hf, but I'll be damned if I could get getopt to see the optional argument. Either I can't read the getopt documentation properly (most likely) or there's something funny going on... If 384 was the default before then perhaps 512 is a bit limiting - you're already most of the way to the limit. What do your tests show - any difference between 384 (the default) and 512 ( the new max)? I wonder what 768 would look like ;) I'm not sure now why I put a limit on at all. That's not like me. The only way I can see any difference along the continuum from 0 to 512 is to use a clean source with lots of detail, take screenshots, and then flip between them on my computer. Very fine detail does slowly disappear, and the noise jumps about a little. I probably couldn't see any of it on a tv. This whole exercise has got me wondering what the "right" way is to design the quantizer matrix - here we are just multiplying some default by a ramp with the given slope, but is a linear ramp the right thing? Should it be quadratic? Logarithmic? With the effect already so subtle I wouldn't even know how to go about evaluating. So I'll probably stick to linear. > This might be useful for those that want some extra bitrate reduction > but find that the current level results in unacceptable artifacts. I I gotta get me a new TV then - I haven't seen artifacts, or rather the ones I do see are the "shades of grey" problem which my feeble attempt made worse in most cases (as it turns out using the yuvmedianfilter on the chroma only is almost as good as y4mblackfix was). Someone earlier said that they got heavy edge ringing. They might try using a value of 128 or 256 and see if the ringing is reduced.

Press enter to start recording>Recording time : 0.00.00:00 Lost frames : 000 A/V sync ins/del: 000/000 Audio errors: 000 Here is a listing of '/dev/v4l': [EMAIL PROTECTED] root]# ls -l /dev/v4l total 0 crw---1 root sys 81, 224 Dec 31 1969 vbi0 crw---1 root sys 81, 0 Dec 31 1969 video0 crw---1 root root 81, 1 Mar 21 00:10 video1 As usual, I am stumped :-( Any other thougths or ideas are greatly appreciated...

Previously, I had had my bttv card module loaded as '/dev/v4l/video0'. Maybe I'll try to do a mknod on '/dev/v4l/video1', and see if that works... > Why not just do "for i in $(seq 0 3); do mknod > /dev/video$i c 81 $i; > done && ln -s /dev/video0 /dev/video"? Forgive me for this likely stupid question... in theabove, what does the '$(seq 0 3)' reference? Thanks!

I'm guessing /dev/v4l/ doesn't exist or so. Why not just do "for i in $(seq 0 3); do mknod /dev/video$i c 81 $i; done && ln -s /dev/video0 /dev/video"?
