converting to mpg using convert

dovkruger · 10-06-2005, 04:30 PM

the command:

convert *.png out.gif

works and creates an animgif

the command:

convert *.png out.mpg

does not work because it cannot find the command mpg2encode
is not found. The only reference I can find to that is an obsolete (unsupported) mpeg client at mpeg.org.

I assume there are other ways to get the convert utiltiy to convert a sequence of png to an mpeg, or perhaps a totally different program in Linux?

Why is this in the Programming forum? You're much better off posting in the forum related to what you're asking.

Walk me through why you think that a sequence of png formated images can be make into an animated image. In particularly a video movie image format.

>Why is this in the Programming forum?
The programming forum is a hodge podge of stuff. There does not appear to be any other forum as relevant to this question. I might well ask why various problems in C++, Java, etc unrelated to Unix are here. This is a UNIX-based programming question. I want to write a shell script, or perl, or C++ or Java for that matter, program to convert a sequence of images to an mpg. I am fairly sure this is reasonably easy to do, and have no desire to do it at the library level.

Huh? Did you read my post? How about BECAUSE I'VE DONE IT?

I think my initial post established that I can convert a sequence of png files to an animgif, and that clearly the intention is that convert should be able to convert to an mpeg, since it tries to invoke a program called mpeg2encode, but the encoder is not there on Red Hat EE 3. I'll gladly take any solution. I didn't think it would be difficult.

to give you a hint; i have used this in a scriptfile to generate a avi or also an mpeg file from jpgs or pngs

Code:

mencoder 'mf://*.jpg' -mf type=jpg:fps=7 -ovc copy -oac copy -o movie.avi

Great answer! I didn't know mplayer had an associated encoder, and it's already on my system because I installed mplayer.

I get some errors related to missing files. Any suggestions?
