Hello,
Using mjpeg tools capturing from a matrox g400 and matrox g200 the output avi
files cause a segfault a few frames into encoding. I suspect this has
somethign to do with the sound- I tried seperating the input file into just a
video.avi and sound.wav file. Encoding just the video.avi worked properly
(but without sound unfortunatly), but when adding -audiofile sound.wav the
crash reoccurs.
I have tried encoding from a dvd (mencoder -dvd 1 -ovc divx4 -oac mp3lame -
divx4opts br=1200:q=5 -o dvd.avi) and it worked properly, if that is relevant
Thinking this had something to do with the compiler, I've tried gcc 2.95.3,
2.96.110 and gcc 3.0.4 (all on seperate installations of linux)
My report is as follows:
