This is an improved version of Movietool version 1.2. Movietool is a display tool for sequences of Sun rasterfiles, providing "video animation" in a SunView window. Movietool may also be used as a multi-rasterfile previewer. Version 1.3 is mainly improved in its handling of colors: Colormaps with less than 256 entries are now better handled. Furthermore, since Sun monitors tend to show colors as rather dark, an interactive facility has been added for brightening colors using "Gamma correction". For video recordings using Movietool, a fade-in/fade-out feature has been added. How to obtain movietool: ------------------------ From titan.rice.edu you get the files movietool-1.3_kit[1-5], movietool.uu.[1-6] (an audio file), and possibly movieras.uu.[1-34] (a sample movie in monochrome). These files are also available by anonymous FTP from oersted.ltf.dth.dk (129.142.66.16) in the ~/pub directory as movietool-1.3.shar.Z, movietool.au.Z and movietool.rasters.tar.Z, respectively. Please use titan.rice.edu from the American side of the Atlantic. If you don't have FTP access to Internet, please send mail to the Rice archive server (mail the word "help" to "archive-server@rice.edu". [[Ed's Note: Here are the relevant files: -bdg]] FTP Hostname : titan.rice.edu (128.42.1.30) Directory: sun-source Filenames: movieras.uu.[1-34] movietool.uu.[1-8] movietool-1.3kit[1-5] Filesizes: movieras: 34 files totalling 670690 bytes movietool.uu: 8 files totalling 140531 bytes movietool kit: 5 files totalling 103515 bytes Archive Server Address: archive-server@rice.edu Archive Server Command: send sun-source (filename-see above) Testing: -------- There is a sample movie in monochrome which may be unpacked from the file indicated above (almost 1 Mbyte in 50 files). To play this movie, say "movietool tp*". To do: ------ The decoding of RT_BYTE_ENCODED images would ideally be performed by a graphics hardware accelerator such as the GX, reducing CPU and bus load. My information is that the GX hardware will never be able to handle run-length decoding. Hopefully, someone with more detailed knowledge (hint: Sun Microsystems) might find a way to do this on the GX or one of the other accelerator boards. In addition, it would be great is someone who knows the SPARC assembler would recode and optimize the module pr_decode.c in order to boost performance. ANYONE VOLUNTEERING ?? I will convert Movietool to XView once we decide to use that window system. However, the trick of setting window Clipping=False to write directly on the framebuffer may be hard to implement with an X-windows server. If anyone knows how a C application can write directly to the framebuffer of an X screen, please tell me ! Author: ------- Ole H.
