I'm using the tools to do marvelous things with some video I have. I just wanted to say thanks to someone. Hope that's not too dumb. I love these tools.

[Mjpeg-users] VCD easy (hopefully) question
I'm not having a problem with the tools per se, but a problem with my DVD player. I need to fool it. Question below code. This works: transcode -i $infile -V -y yuv4mpeg,mp2enc -F 1 -Z 384x240 -E 44100 -b 224 -o $outnam || exit 1 So does this: transcode -k -i $infile -V -y yuv4mpeg,mp2enc -F 1 -E 44100 -b 224 -o $outnam || exit 1 ( (mv $outnam $outnam.yuv && cat $outnam.yuv) \ | yuvscaler -n n -O VCD -M RATIO_512_352_384_240 \ | mpeg2enc -f 1 -o $outnam.m1v ) || exit 1 I did the second crazy thing because I was hoping that yuvscaler was going to add black bars at the top and bottom. Turns out it doesn't need to at that ratio... Incidentally, if I use RATIO_512_352_384_210 it adds the bars, but squishes the video top to bottom (obviously). The problem is, my DVD player cuts off 10 or so pixels from each side, and 15 or so from the top and bottom. When I try to play the VCD it renders some of the subtitles off the screen -- not to mention some of the video. I imagine everyone's NTSC equipment does this to a certain extent, but the subtitles are the real problem. The actual question: Is there some trick I can use to fool my DVD player into clipping less of my video; while still preserving the desired aspect ratio? I was shooting for thin black bars the whole way around, but it turns out yuvscaler won't do that. -- If riding in an airplane is flying, then riding in a boat is swimming. 50 jumps, 15.0 minutes of freefall, 31.3 ff vertical miles. --- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.

Re: [Mjpeg-users] VCD easy (hopefully) question
No bites at all... *sigh* Let me ask mor simply then. Is there a way to get yuvscaler or some other tool to add black bars to the sides of stream?

Actually, combining the y4mscaler and yuvscaler seems like a good idea, but it hardly matters unless I learn the way to get transcode to pipe into the scalers. -- If riding in an airplane is flying, then riding in a boat is swimming. 50 jumps, 15.0 minutes of freefall, 31.3 ff vertical miles. --- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.

Please help... I figure I'm missing something stupid because there's nothing on google about this -- and the error message has the rare distinction of having spelling errors in it (making it easier find). This is the first day I've tried mjpegtools, so naturally I ran but didn't walk to the howto: http://sourceforge.net/docman/display_doc.php?docid=11305&group_id=5776#Images I happen to have 50 images I wish to encode. So I tried a quite a few of these (all with different switches and options): jpeg2yuv -f 25 -j image%05d.jpg > r.y cat *.ppm | ppmtoy4m > r.y When I pump the .y's to mpeg2enc though, I get: "Could not get image dimenstion and frame rate from input stream" Worse yet, I don't see a way to specify the image dimensions in the man page. It may be there, but my question is really, why can't it read the image dimension and frame rate from my .y's? -- If riding in an airplane is flying, then riding in a boat is swimming. 50 jumps, 15.0 minutes of freefall, 31.3 ff vertical miles. --- This SF.net email is sponsored by: SF.net Giveback Program.

Appolgies around, it would seem a very ancient install of mjpeg2enc was before the current version in my PATH. It took me nearly four hours and many many package upgrades to figure out. But the version that produces that error is long gone. -- If riding in an airplane is flying, then riding in a boat is swimming. 50 jumps, 15.0 minutes of freefall, 31.3 ff vertical miles. --- This SF.net email is sponsored by: SF.net Giveback Program.

[Mjpeg-users] hello
I've been having a whale of a time making all sorts of movies and things with mjpegtools. I love it. I'd appreciate some help with audio. And I've made 4 coasters trying to sort it out. Oddly enough, my SVCDs play fine on my special xbox (software decoder evox/xbmp), just not on my (sony) DVD player. Well, strictly speaking, they play fine, but the audio skips horribly. Here's how I encoded my movie: SVCD: cat ~/code/povray/outdoorexp/o/o*.ppm | ppmtoy4m -S 420_mpeg2 > ntsc.yuv cat ntsc.yuv | yuvscaler -O SVCD > ntsc_scaled.yuv cat ntsc_scaled.yuv | mpeg2enc -f 4 -o ntsc.mpg mplex -f 4 -o ntsc_mplex.mpg ntsc.mpg audio.mp2 vcdimager ntsc_mplex.mpg cdrdao write --device 0,0,0 videocd.cue SVCD mpg123 --wav - music.mp3 | mp2enc -V -o audio.mp2 -- If riding in an airplane is flying, then riding in a boat is swimming. 50 jumps, 15.0 minutes of freefall, 31.3 ff vertical miles. --- This SF.net email is sponsored by OSDN's Audience Survey.

Re: [Mjpeg-users] hello
> Are you sure that your DVD player handles SVCDs? I would certainly guess so, since it plays... the only problem is the horrible skipping. I suppose that doesn't prove anything, but it's still my guess. I will probably try it in VCD format, though, I wanted to use mpeg2, and I thought VCD was mpeg1. -- If riding in an airplane is flying, then riding in a boat is swimming. 50 jumps, 15.0 minutes of freefall, 31.3 ff vertical miles. --- This SF.net email is sponsored by OSDN's Audience Survey.
