Yes, and all I'm asking is: how to do it :-)
At first, it seemed to me it should be quite simple, something like convert
foobar.tif foobar.jpg, now I've dig through tons of manuals, installed
megabytes of movie-related software, tried a hundred options, and I'm still
as stupid as I was before.
Take, for example, mencoder -ovc lavc -lavcopts vcodec=mpeg1video foo.avi
This should turn the file into an mpeg layer 1 avi, am I correct? Well,
it doesn't work in either QTP or WMP.
Really, I have been struggling with it for the last week or so. Here is a
small exemplary file: hell.pl/january/mysz/mysz.avi (you will find several
of my attempts to convert it in the same folder(*)). If any of you manage
to convert it to a QTP or WMP playable version and tell me how you did it,
I can send him a postcard from Heidelberg or buy a beer if we meet one fine
day :-). Or help to troubleshoot any problem you might have with
quantitative PCR, sequence database search or LaTeX or whatever I can :-)
(*) Contents of hell.pl/january/mysz :
mysz.avi - the original mjpeg file
mysz*.avi - files created with different lavc codecs.
mysz.mpg - this one is working in QTP and WMP, albeit at 25 fps. I did it
mencoder -ovc lavc -lavcopts vcodec=mpeg4 mysz.avi
transcode -i test.avi -o mysz -V -y mpeg
mysz25fps.mpg - this one has the poor quality, but the right speed. It
was done like this:
mencoder -ovc lavc -ofps 25 -lavcopts vcodec=mpeg4 mysz.avi
transcode -i test.avi -o mysz25fps -V -y mpeg
