Re: [Mjpeg-users] mpeg2enc is feeling better
Hi Andrei, Well, yeah, but code doesn't change all by itself - there are people making the decisions, etc. Basically, it looks like mjpegtools has a too long development cycle. All the good stuff is always in CVS, and it stays there for years. I guess you're probably still a young fellow ... ;-). As ever in SW engineering its not the *deciding* (despite what countless books for non-coding project managers and bosses might lead you to believe) its the *doing*. And *doing* needs oodles of time. When I was young(er) and still working as an Academic I could really motor along on my open-source projects. Seriously, as you get older you not only have less time but also more money to indulge in other distractions. I would *love* to get a solid 8-16 hours a week in on mpeg2enc/mplex like I used to years ago but I now have (in no particular order): a wife, a young son (cute!), a day-job doing equally interesting SW engineering, a house, and enough money to indulge my motorcycle-racing habit. If I'm honest another factor is that technology has moved on and I simply no longer *need* to compress recorded video for myself anymore (all MPEG-2 DTV, soon H.264 HDTV). Longer term the future for 'on-computer' video is clearly with H.264. MPEG-2 lives primarily so folks can burn standard DVDs. Its like (S)VCD. 2-3 years back a hot topic. Now... nil interest. If I could find an interested person wanting to take over as 'owner' I'd gladly invest time in explanation/support to do a proper hand over. So far no interest. Hopefully (I work from home nowadays) I'll have a bit more time this winter and push mpeg2enc forward again! cheers, Andrew -- Dr Andrew Stevens Erdingerstrasse 23 85464 Neufinsing Germany Home: +49 8121 883672 Mobile: +49 173 5397553 - This SF.net email is sponsored by: Splunk Inc.

Ever played with larger values for -r when the source is a fairly good (new) DV camcorder? Worth bumping it up? None (at present). -A 0 currently selects a limited local single-GOP look-ahead two pass encoding rate control. Here basically if simple heuristics used for the first encoding pass produced erratic quantisation with frames varying wildly in quantity or GOP boundaries in bad places a second pass is switched in to use the information from the first pass to do a better job. There will eventually also be a 'pass 1.5' where if lots of action means blockiness is likely the encoder will re-encode with low-pass filtered source material to allow blockiness to be eliminated. -A 1 will (when its done) do statistical look-ahead rate control. This will basically run an entire 1st pass, or 1st pass over a statistical sample of GOPs, to work out the pattern of image complexity in the encoding. A second pass will the encode using that information to accurately hit an average bit-rate / size target trying to trade bits as much as the decoder buffers allow between GOPs to maintain the best perceived image quality. The major changes / bugs in the 1.9 revision of mpeg2enc relate to major internal changes needed to support this internal encoding and re-encoding of images (and provided hooks for improving multi-core scalability). cheers, Andrew -- Dr Andrew Stevens Erdingerstrasse 23 85464 Neufinsing Germany Home: +49 8121 883672 Mobile: +49 173 5397553 - This SF.net email is sponsored by: Splunk Inc.

Re: [Mjpeg-users] hi-res matrix - not the best image quality?
Hi Andrei, Is it possible that the hi-res matrix does not provide the best image quality? It is very possible! The 'hi-res' matrix does not roll of higher coefficients for inter-coded frames at all. As such it only sane if you have LOTS of bits. If you have less bits a matrix that trades a bit of (theoretical) texture detail for (practical) reduction in quantisation will be better. This is the custom matrix (suggested by Steven Schultz a while ago): ... Note that these tables are actually available in the encoder. I tend to use them myself all the time. Select matrix 'tmpgenc'. Should perhaps be made default... cheers, Andrew -- Dr Andrew Stevens Erdingerstrasse 23 85464 Neufinsing Germany Home: +49 8121 883672 Mobile: +49 173 5397553 - This SF.net email is sponsored by: Splunk Inc.

Re: [Mjpeg-users] mpeg2enc is feeling better
Hallo The author/maintainer of mpeg2enc has obtained a modicum of development/free time and has checked in, today, changes to mpeg2enc that restore (or should restore ;)) normal operation and produce non corrupted video. So, do a 'cvs update', rebuild and commence testing. I said this before - you guys should make releases way more often. Very few people are going to track the CVS. If everything goes well, I can create a RC 3 next weekend. And that would be worth testing. 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: Splunk Inc.

Re: [Mjpeg-users] mpeg2enc options
Hi Andrei, So how usable is 2-pass encoding with 1.9.0-rc? Not at all useable - there's still some bits not yet programmed. The -A 0 stuff is all there and up and running already. Is 2-pass already documented somewhere? (for users, not for programmers) There's not much to document it actually be easier to use. Simply tell it how big you want the end-result to be and the maximum data-rate that can be handled and the encoder will worry about the rest itself. Whats missing is sensible auto-setting of noise/content dependent parameters (like -Q -X). This is, of course, much easier in a two-pass or look-ahead setting where you have decent statistics in advanced of needing them... cheers, Andrew -- Dr Andrew Stevens Erdingerstrasse 23 85464 Neufinsing Germany Home: +49 8121 883672 Mobile: +49 173 5397553 - This SF.net email is sponsored by: Splunk Inc.

Currently I set the max bitrate to 8000 to avoid spikes, but I assume 2-pass will be much better and presumably the max bitrate could be set pretty close to the maximum allowed by the DVD standard. Right? This will be a very good feature when it gets released. -- Florin Andrei http://florin.myip.org/ - This SF.net email is sponsored by: Splunk Inc.

Maybe the output of this command could be used to make a decision when lavtools/Makefile is generated? No, it can't. Some systems don't use X11 to do their SDL output. On another system I have the sdl-config --libs gives: -L/usr/local/lib -lSDLmain -lSDL -Wl,-framework,Cocoa -Wl,-framework,OpenGL A better workaround would be to edit the sdl-config script and add Hm, if I do that, I wonder what other things may break. I don't think anything will break. I'll look into the problem some more. There's only 1 place in lavtools/ that might need X11 - so maybe a more specific test can be found.

Did some tests, using a low-light sample and another in broad daylight, with the same cheap digital camera. It's pretty hard to distinguish between the custom matrix and tmpgenc. They pretty much look the same to me. Both are clearly better than the default and the hi-res matrices, which have massive (by comparison) artifacts and blockiness. -- Florin Andrei http://florin.myip.org/ - This SF.net email is sponsored by: Splunk Inc.
