Introduction + +In the tradition of the Unix computing philosophy, here is +yet another operator that does one simple task, namely the +creation of an AVI MJPEG file given a list of JPEG/JFIF files. + +I had some difficulty in performing this extremely simple task +in Linux, mostly because it is so simple and all of the existing +code to do it lie at the bottom of complicated and more ambitious +projects--e.g. xawtv, avifile, etc. I then had to waste +time reading M$ docs and xawtv source to find out how to do it. + + +II. Installation + +The code is pretty basic, and so it should be pretty easy to +install: "make all" compiles the program, "make install" +installs it. If you want the files to reside in some directory +besides /usr/local/bin and /usr/local/man, edit "Makefile". + + +II. Usage + +There are three basic modes of operation: + +1. jpegtoavi per_usec width height img1 [img2 ... imgN] +2. jpegtoavi -f fps width height img1 [img2 ... imgN] +3. jpegtoavi -fsz img1 [img2 .. imgN] + +The first two print an AVI to STDOUT using the width and height +parameters and the images named in chronological order. (No +checks are made on the validity of the JPEG/JFIFs or their +dimensions.) The first mode specifies the frame rate in +terms of the period in microseconds for each frame, whereas +the second specifies frames per second. + +The third mode was added to give size hints during the transfer +of AVIs without the use of a temporary file. Instead of +generating the AVI it outputs the size in bytes that of the AVI +that could have been generated. + + +III. Contact, Bug Reports, and Suggestions + +Send them to me at dI77IHd@yahoo.com
