03 Dec 2009	mmwrite write AVI/ASF/WMV/WMA file from movies read by mmread Author: Micah Richert	Thanks Micah, Unfortunately the 64-bit version still seems to have issues with Server 2003 R2 even if I'm sure DirectX is installed. You probably don't have a computer with that OS to try, so if I ever make it work I'll let you know. Otherwise I'll just have to save AVI's with Matlab's function in 64-bit and go into a 32-bit Matlab and convert them.
01 Dec 2009	mmwrite write AVI/ASF/WMV/WMA file from movies read by mmread Author: Micah Richert	Also, I am trying to run the function and keep getting similar error to Caglayan: Invalid MEX-file '...MATLAB Path...\mmwrite\mmwrite.mexw64': The specified module could not be found. For me I get this same error when I run either mmwrite('blah.wmv',mov) or list=mmwrite('ListAviVideoEncoders') I tried installing ffdshow (supposedly 64-bit version of klite) but to no avail. I'm not sure where this depend.exe file can be found, but is it possible I'm missing a file or a codec still? Thanks again!
30 Nov 2009	mmwrite write AVI/ASF/WMV/WMA file from movies read by mmread Author: Micah Richert	Micah, Thanks for your work on writing video files using Matlab. I was wondering if you have any further insights into making mmwrite work with 64-bit windows? I am running 2009a 64-bit Matlab on a Windows Server 2003 R2 64-bit OS. Also, is there any possibility of including MPEG capabilites, or am I out of luck. Thanks so much!
30 Nov 2009	mpgwrite The MPEG converter takes a MATLAB movie matrix and writes the movie to disk as an MPEG file. Author: David Foti	Anyone that wishes to help, I am having trouble compiling (via makedll.m) the source code. I am attempting to do this on a Windows Server 2003 R2 64-bit computer running Matlab 2009a 64-bit and using the Visual Studio 2008 Express and Microsoft Platform SDK R2 as the compiler. Can the source code as written be used to create a 64-bit mex-file version of mpgwrite? If not, are there any mpeg creating functions that can run on 64-bit windows? Hope someone can help me! Thanks so much in advance!

19 Jan 2012	mpgwrite The MPEG converter takes a MATLAB movie matrix and writes the movie to disk as an MPEG file.	Julia	Seems to work so far. Just wanted to say I'm running Windows and was having the same trouble as many people, but Andrea's detailed advice on installing and using Visual Studio as a compiler made all the difference. I'm copy-pasting the key part from the website Andrea linked, even though it's long, since this was the key part for me. http://grantnz.blogspot.com/2010/07/compiling-matlab-mpgwrite-with-vs2010.html Compiling Matlab mpgwrite with VS2010 for 64 bit Windows I was having trouble producing Matlab movies of reasonable quality on my 64 bit Windows 7 laptop until I was able to compile and run mpgwrite (source available from Matlab Central http://www.mathworks.com/matlabcentral/fileexchange/309-mpgwrite). It wasn't obvious how to get this to compile and run so in case someone else would like to do this I've documented what I did: 1. Ensure Visual Studio 2010 installation includes the "X64 Compilers and Tools" (and option under the Visual C++ feature in the Visual Studio 2010 installer). 2. Configure the mex script for VS2010. Matlab R2009b and earlier doesn't directly support Visual Studio 2010 but you can still use it by running mex -setup from Matlab. a. Answer n to the first question (Would you like mex to locate installed compilers [y]/n? ) b. Select "Microsoft Visual C++ 2008 SP1 " (option 5) c. The script will output: The default location for Microsoft Visual C++ 2008 SP1 compilers is C:\Program Files (x86)\Microsoft Visual Studio 9.0, but that directory does not exist on this machine. Use C:\Program Files (x86)\Microsoft Visual Studio 9.0 anyway [y]/n? Answer n d. Locate your Visual Studio 2010 installation folder and enter this in response to the next question. Visual Studio 2010 was probably installed to C:\Program Files (x86)\Microsoft Visual Studio 10.0 e. Finally, you will be asked to confirm the settings and Matlab will create a file mexopts.bat with the configuration information. 3. From Microsoft Visual Studio 2010\Visual Studio Tools open "Visual Studio x64 Win64 Command prompt (2010)". 4. Change to the src folder of the downloaded the mpgwrite source code using the "cd" command. 5. Edit the file makefile and replace $(MCC) $(MCFLAGS) after the call to mex with -v -DWIN32 That is, your makefile should contain: mpgread: mex -v -DWIN32 mpgwrite.c mfwddct.c \ postdct.c huff.c bitio.c mheaders.c iframe.c \ pframe.c bframe.c psearch.c bsearch.c block.c \ mpeg.c subsampl.c jrevdct.c frame.c fsize.c 5. Run nmake -f makefile 6. This should generate the file mpgwrite.mexw64 Copy this file to a folder on the matlab path. You should now be able to generate mpeg movies from matlab.	Comment only
19 Jan 2012	mmwrite write AVI/ASF/WMV/WMA file from movies read by mmread	Howard Schoeberlein	I'm having trouble getting mmwrite to work. I get errors looking for a module in mmwrite.mexw64: "??? Invalid MEX-file 'U:\MATLAB\MovieTest\mmwrite\mmwrite.mexw64': The specified module could not be found." I added the path via addpath. Any ideas? Thanks, Howard	Comment only
05 Jan 2012	mpgwrite The MPEG converter takes a MATLAB movie matrix and writes the movie to disk as an MPEG file.	Amir	To Dan Massie (03 Nov 2011) : the problem you noticed is due to the limitations of getframe command ( see http://www.mathworks.com/help/techdoc/ref/getframe.html ), and has nothing to do with mpgwrite.	5
