There were changes in mpeg2enc, but the bitrate control shoul be the same as it was in in the release before. Andrew changed the reate controll, before the 1.6.2 release, but that version was causing problems. So he had reverted it back to the version before. 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: Oracle 10g Get certified on the hottest thing ever to hit the market...

[Mjpeg-users] Image stabilizer added
Hi - Another new program has been added to the CVS version of mjpegtools. 'y4mstabilizer' reduces the jerky images produced by camera shake. I didn't write it - but the author is a member of both the -devel and -users mailing lists so reports of bugs can be made to the list. No manpage (yet) but the usage() summary is (in the author's words) "verbose" and has example uses. Enjoy!

[Mjpeg-users] New denoiser in CVS!
For those of you brave enough to try the CVS version of mjpegtools, our new denoiser has been checked in & made a part of the standard build! It's called "y4mdenoise". It comes with a man page to help you figure out how to run it. http://195.70.35.24/~ulatekh/ contains examples of the denoiser in action. Enjoy! And please let me know what you think of the new denoiser!

The picture looks normal when viewing the program on the tv in a normal fashion. I have the lml33 input connected to a vcr and the output connected to a tv so I can view on the tv what I'm recording thru the lml33. If I view the program thru the lml33 while i"m recording it is too bright. > > > Does anyone have a lml33 working on a 2.6 kernel? > > Worked fine for me last time I tested it (which was right before I > submitted the new driver for inclusion in the 2.6 kernel). > > Ronald > --- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...

Worked fine for me last time I tested it (which was right before I submitted the new driver for inclusion in the 2.6 kernel).

Re: [Mjpeg-users] Novice needs help with bright washout
I have the output connected to a tv. It makes no difference connected or not. I run "v4lctl bright 0" and the tv that the output is connected to flickers and returns to normal. If I run "v4lctl show" it returns "bright: 0" but when I record the picture is the same. Too much white. I'll try to dig deeper if someone can suggest where to start. The LinVS package that comes with the lml33 will not compile on 2.6 so I can't even test it. Does anyone have a lml33 working on a 2.6 kernel?
