does anyone of you ever used one of these Mencoder compiles? For example there is a special precompiled Mencoder binary - XviD 1.1.0 - x264 svn...

I'm going to test it but not tonight

Build mplayer/mencoder win32

Hello everybody,

Somewhere in the forum I had recently seen a thread with detailed information regarding how to build mplayer/mencoder for win32 with cygwin or mingw. Does anybody know where I can find that specific thread?

I think I found a bug in megui. I stupidly postet in the x264-thread.

been thinking about getting back into programming(i did program assembly language mostly 6502 and 68000 long time ago) - i can follow c# code to a degree - but can anybody recommend any c# books (free ebooks or whatever) - and i will try some debugging and that if i can

Just wanted to say thanks to the developers of meGUI (esp Doom9) and also the developers of the tools it uses (x264, avisynth, etc).

I used it for the first time a few days ago and I was impressed.

Troubles...

I am trying to use MeGUI, but I can't seem to get it to work. I have all the tools setup and pointed to properly, I start the program up and set it up to encode 3 pass x264, but it's not working. Here's a copy/paste of the logfile:

well.. you really should use the more up-to-date threads.. digging up old stuff is bad etiquette and just clutters up the forum.
My guess is your x264 build doesn't support the

There's not much point in doing a 2pass quantizer encode since there's no bitrate target that needs to be met with a quantizer encode, so x264 will get it right the first time. Anyway, if you are very picky about it, then you can do a first pass with a constant quantizer, get the bitrate of the file from the log, and then do a 2pass encode with that new bitrate, but seriously, why?

oh sorry. then i thought 2 pass would increase the quality a bit. i encoded a video at a 32 quantizer and the file size can out reall good. but the issue was the video was 640x480 and when i watched it full screen i saw a lot of blockyness. i thought 2 pass would make that better.

will it?

Yes and no. Doing a second pass after a constant quantizer encode will pretty much not add anything, because it won't have a a proper first pass. However, a 2pass encode to the same filesize will look better, because 2pass is simply a better algorithm. You should never really use constant quant, because constant quality mode is better.

Nevertheless, 32 quantizer is always going to be bad. You should experiment with values between 18 and 26.

i tried 25. but that came out even worse. and when i checked the bitrate (while playing under media player classic) it was 30-40 Kbps.

is that right i thought lower quantizer was better. ?

IIRC at crf 20 filesize can get as big as XviD at q3, IMHO a big waste. I'm always using crf 22 which gets 30-40% smaller than 20.

I think you forgot to switch it back to constant quantizer/quality mode. It sure sounds like bitrate mode was engaged.

OK, I waited exactly five days to post... :P. I wanted the MeGUI x264 compile and source code only. All previous links in other threads appear to be dead and I could not find anything. I did take look at x264 GUI but its in VB.NET and does not really serve the purpose.

Can I have a link to MeGUI x264 build part only with source code. I really want to work on it.

MeGUI-x264 was dropped.
please refer to the sticky thread (on top of this board) for MeGUI (full version) bins and sources.
very latest binaries of megui can be found on http://x264.nl in the GUI section.

hmm, I suspected that. But is there a way I can get an older source and build?

i really dont know. i do not mantain older sources but you can ask the other megui devs if they still have archived the latest megui-x264.

via CVS

btw. Why do not use MeGUI full?
