So you did something like: convert *.jpg -geometry 180x120 ppm:- | ppmtoy4m >/dev/null If you only have a few frames make a yuv file, and start than mpeg2enc in a second step: convert *.jpg -geometry 180x120 ppm:- | ppmtoy4m >file.yuv cat file.yuv | mpeg2enc -o test.m1v So you should see which programm is failing. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard --- This SF.net email is sponsored by: SF.net Giveback Program.

[Mjpeg-users] Problem with mpeg2enc
I'm trying to create an mpeg movie from a sequence of jpegs shot with my digital camera.

Anyway, Q 10 in the new driver is the same as Q 20 in the old driver, so you might want to try --quality 10 instead of 20.

[Mjpeg-users] Timer expired with latest 2.6 kernels
Hi, Since the latest 2.6 test kernels (test5..test9) I cannot record with lavrec anymore, while it used to work with 2.6.0-test4. The error message I get is: Press enter to start recording> Press enter to pause recording ++ WARN: [lavrec] Closing file(s) and exiting - output file(s) my not be readable due to error **ERROR: [lavrec] Error syncing on a buffer: Timer expired **ERROR: [lavrec] Error writing to output file Test_01.avi: Internal: broken JPEG format ++ WARN: [lavrec] Closing file(s) and exiting - output file(s) my not be readable due to error **ERROR: [lavrec] Error resetting buffer-queue: Invalid argument0.000 Recording time : 0.00.00:00 Lost frames : 000 A/V sync ins/del: 000/000 Audio errors: 000 As you see, it doesn't record anything. I get the same when I don't record sound, so it cannot be the sound driver. The commandline used is: lavrec --format a --input p --decimation 1 --quality 20 --stereo --audio-bitsize 16 --audio-bitrate 48000 --file-flush 10 --wait "$1_%02d.avi" Any suggestions?

Re: [Mjpeg-users] DVD plus or minus?
Hi Florin, > It difficult to tell which way the market will go. > However, the vast majority of the newer DVD players will happily play > both formats, even when they only advertise one of them. Strange, isn't? Not really. Almost all DVD Players now use standard ATAPI drives plus one of a few Chipsets with (usually) nothing more than power-on-logo and menus tweaked from reference Firmware delivered by the Chipset vendor. Whether the or a 'manufacturer' (who really only designs the case, or even just makets) 'supports' a standard is mainly a matter of which industry grouping they're supposedly part of. I'd like to say it is a question of which standards they validate but nowadays that seems to be the customers job. I say: 'hurray for China and Taiwan'. Those guys don't give a flying cuss about the lame politics of the big brands they just care about price (often a bit too much about this) and delivering maximum functionality to put on the side of the Box. Hence region-free DVD's that play anything under the Sun (and then some). Competition, when it really exists, is a wondeful thing... cheers, Andrew --- This SF.net email is sponsored by: SF.net Giveback Program. Does SourceForge.net help you be more productive?
