[Mp4-tech] Memory Requirement for JM reference code

[Tourapis, Alexis]

Please note that if you are only concerned with 8 bit content you should also try and set #define IMGTYPE to 0. We are also working on several optimizations in the upcoming versions which would change the memory footprint of the software considerably. 
Tools like vtune, valgrind, electric fence can provide some info on how memory is used beyond optimizing/debugging. They may not be at the fine grain level that you want them, but maybe that is a start for you.
Best regards,
Alexis

Instrument all malloc, calloc, and free calls to keep track of the maximum heap allocation. Run Windows Task Manager and enable the “Peak Memory Usage” column. Run the instrumented JM encoder at various image resolutions and graph the results. The amount of memory used depends upon the image size. After you have plotted the results, please post so that future googlers can find them.

Dear all,
I’m working in H.264 decoder.I have downloaded the JM reference code.I would like to find out the memory it takes i.e for 
Global variables
Static variables
Heap and progarm memory that the JM decoder requires in the VC++ version.
I tried googling.But I could not make it out.
I will be very thankful if some one helps me in this regard (as soon as possible)….
Please reply me soon
Thanks in advance
Regards
Gomathi.
