Hi, i want to report a problem i encounter with mencoder (this time _with_ proper bug report, i hope ;-) encoding to xvid (in divx4/5 compat. mode) When i try to encode a video (tested with several source mpegs) to lavc all works as expected, when using xvid instead, the output avi is way too large and only contains very colourful macro blocks :-/ I like to say here, that this once worked with earlier mplayer/mencoder versions, and even with todays xvid, so its quite xvid independant ! (see below) I use the following commandline to encode to xvid: cat $SRC | /usr/local/bin/mencoder -v -v -o out.avi -oac mp3lame -ovc divx4 -divx4opts br=900:q=5 -pass 1 -- - and after that -pass 2 ! If i use large input files sometimes giant output files are created on the first frame (mencoder report frame=1) and several gigabyte (!) of out.avi are generated ... However this behaviour was introduced in mencoder since beginning of June this year (from early June, everything was okay!) - maybe this helps !? See bugreport.txt containing system information and output.txt for stdout/errout from mencoder calls attached ! However seeing output from mencoder makes me think that only 5 frames are encoded ? I like to mention here that these 5 frames take 3,2 MB as out.avi :-( I did some earlier encodes that created an output file even larger, which could be played back, but had completely crazy colours (flickering and really pop-art !) - so maybe some colorspace conversion bug ? Just an idea :-) I hope my descriptions can help finding this problem ! If you need any output files for analysis or anything else just drop me a note ! Martin.
