Hello,

Hopefully someone can help me with this since I've tried everything. I have a lot of video files that are all between 150 and 160 MB large (.avi). I need to be able to play these files within a GUI that I am building.

I have tried aviread, mmreader, etc. and I continue to get an "out of memory" error. I have used MPEG StreamClip to try and decrease the size of the files. They play fine when opened outside of Matlab but inside matlab the implay/mplay commands result in a video with lines going through it (from interleaving i think).

Is there any way to make this work? As stated I have tried reading in each frame with mmreader per the example in the Matlab help and have tried aviread.

thank you,

Portia

One way would be to use the second input to aviread(file_name,INDEX) to read in smaller chunks at a time. You could then convert data types to ones that use a smaller memory footprint or downsample your movie.
